Hidden Risk of Investing in High PE Stocks

Modified: 08-Jun-21

Every investor, be it in any stock market across the world, would have come across many stocks, which trade on a sky-high price to earnings (PE) ratio. The PE ratio sometimes crosses all reasonable levels of valuation logic; sometimes even crossing levels of 100!

I have been repeatedly asked by many investors whether they should invest in such high PE stocks and why I always stay away from such companies.

Many investors perceive high PE companies like the ones with assured future growth and very good management. Other investors perceive low PE stocks like the ones with assured problems.

A recent incident, when I received an offer from a broker to buy stocks of an unlisted insurance company of a very reputed financial services group, at a very high PE ratio, made me think about different aspects of investing in high PE stocks. The argument inevitably led to a comparative analysis of investing in high PE and low PE stocks.

The current article is an attempt to put into perspective the odds of success and the hidden risks that investors face while investing in high PE stocks.

Recently, I got an offer from a broker to buy stocks of HDFC Standard Life Insurance Company Limited at ₹195. The company is not listed on stock exchanges, therefore, there are limited opportunities to buy its stocks.

HDFC Standard Life Insurance Ltd Offer Letter

I am always willing to explore stocks; therefore, I thought about doing a preliminary analysis of this opportunity. HDFC Standard Life Insurance Company Limited provides its financials, annual reports, investor’s presentations on its website. Therefore, it was not difficult to do a brief assessment.

I found that the current earning per share of HDFC Standard Life Insurance Company is ₹3.93, which meant that the current price amounted to a price to earnings ratio (PE ratio) of almost 50 (49.62 to be precise).

I am a value investor who likes to buy stocks cheap; in fact, very cheap. The cheaper, the better. The offer of shares of HDFC Standard Life Insurance Company at such a high level (PE ratio of 50) made me think about the proposition, which should be offered to investors to make them buy stocks at such valuation levels.

Promising Sales Pitch of High PE Ratio Investing

A little thought brought about many factors, which might be put forward to the investors to convince them about such valuation levels. Some of these factors are like:

  • The underpenetrated insurance market in India leading to huge market opportunity.
  • HDFC group having an established management track record, which gives confidence that they would take timely decisions to capitalize on the opportunity
  • HDFC being a recognized brand is expected to attract the required talent to grow at a fast pace
  • HDFC group companies (HDFC Limited, HDFC Bank Limited) have been accorded good valuations by markets in terms of both the price to equity ratio (PE ratio) and the price to book value ratio (PB ratio). This gives the confidence that if HDFC Standard Life Insurance Company Limited repeats the performance of its group companies, then the market might be willing to assign the same level of valuation parameters to it as well.
  • and many more reasons, including that HDFC Standard Life Insurance Company Limited, would come with an IPO later where stocks would be sold at an even higher price. We leave such other reasons for discussion for some other day.

I found that this proposition is no different than any other listed stock, which is currently trading at sky-high valuations of PE ratio of >50x. In all these cases, an investor is presented with an established brand, which is mostly a market leader having a huge untapped market potential for continued future growth. There are many examples of such stocks like Page Industries Limited, Eicher Motors Limited, Just Dial Limited (which until recently, used to trade at PE ratio of >75).

Therefore, the current article is equally relevant for stocks both in public and private markets, which are trading at high valuations.

Assumptions for High PE Ratio Investing to work:

As mentioned earlier that I focus on stocks trading at cheap valuations. However, for a change, I started thinking from the perspective of an investor, who decides to invest in stocks that are presented as having “almost” certain high growth in future:

  • I imagined that the investor had already bought HDFC Standard Life Insurance Company Limited at the offer price of ₹195 currently in the year 2016.
  • I imagined that time has shifted by 10 years (the year 2026) and the investor is still holding the shares of HDFC Standard Life Insurance Company Limited that she bought in 2016 at ₹195.
  • I imagined that over the last 10 years (2016-2026) all the above assumptions about the future growth of the insurance sector and the resultant growth of HDFC Standard Life Insurance Company Limited, have come true.
  • I imagined that HDFC Standard Life Insurance Company Limited is now listed on stock exchanges, in the year 2026.
  • I also imagined that HDFC Standard Life Insurance Company Limited is being valued at similar levels at which other established HDFC group companies like HDFC Limited and HDFC Bank Limited, are trading, after showing decades of sustained good business performance.

With all these imaginations in my mind, I thought about the kind of returns the investor would have made as a long term investor in HDFC Standard Life Insurance Company Limited.

It required some simple mathematical calculations, as below:

  • HDFC Standard Life Insurance Company Limited grows its earnings by an excellent rate (CAGR) of 25%. It is seen that growth rates in excess of 25% are unsustainable over long periods of time and growth, even for established brands, inevitably moderates to such reasonable levels of 20-25%. Take the case of Hindustan Unilever Limited, which has grown by 11% over the last 10 years.
    • Earnings per share (EPS) of HDFC Standard Life Insurance Company Limited after 10 years: 3.93*(1.25)^10=₹36.60
  • HDFC Limited and HDFC Bank Limited are currently trading at consolidated PE ratios of 17.75 and 22.74 respectively (data from screener on February 27, 2016). I assumed that HDFC Standard Life Insurance Company Limited would trade at a PE ratio of 23 after 10 years of consistent growth.
    • Therefore, HDFC Standard Life Insurance Company Limited is assumed to be trading at a price of ₹841.80 in 2026 (=36.60*23)
  • I calculated the amount of return the investor would have made in terms of capital gains for holding HDFC Standard Life Insurance Company Limited for 10 years:
    • Unrealised capital gains: (841.80/195)^(1/10) = 15.7%
  • I assumed that HDFC Standard Life Insurance Company Limited would be paying a dividend to reward its shareholders for the association. Its dividend yield is expected to be about 1-2%, in line with other large-cap stocks. HDFC Limited and HDFC Bank Limited have current dividend yields of 1.43% and 0.83% respectively.
    • Assuming 1.3% of dividend yield provided total return (capital gains + dividends) of 17% per annum (15.7% + 1.3%) for holding HDFC Standard Life Insurance Company Limited for 10 years

An annual return of 17% over 10 years, is a respectable rate of return for any investor. I would be very happy to earn a return of 17%, if it’s reasonably certain, over 10 years.

However, in life, especially in business and equity markets, the environment changes very frequently. Even well thought out assumptions fail to materialize and the growth shown in business models remains on excel only.

Things that can go wrong in High PE Ratio Investing

Let’s see what all could happen over upcoming years, which might prevent HDFC Standard Life Insurance Company Limited to achieve a sustained formidable growth of 25% over the next 10 years:

  • Current market leader, Life Insurance Corporation of India Limited (LIC), might reduce prices of products, which are currently the costliest in the market and it prices them at par or below private competitors. (Nothing beats the assurance of sovereign guarantee for an insurance company as a surety against payment default when a claim needs to be paid. I would have chosen LIC over any other company if its premium for term life insurance plan would have been similar to other players).
    • this one step by LIC has the potential of deflating business models of many non-serious players in the life insurance sector and severely denting the growth rates of others.
  • Government’s ongoing drive to liberalize insurance sector in order to allow infusion of capital by foreign players would make even relatively smaller Indian players who could tie-up with strong foreign partners, as formidable competitors to HDFC Standard Life Insurance Company Limited. It would make the achievement of sustained growth by HDFC Standard Life Insurance Company Limited, difficult.
  • HDFC Standard Life Insurance Company Limited might suffer from human errors in leadership, which may delay its growth plans by a few years.
  • Unpredictable regulators might come out with certain regulations over the next 10 years, which might slow down the business growth
  • Judicial activism/public interest litigations/NGOs might change the entire business environment altogether, which might make even doing business, leave apart growth, difficult and put the entire industry behind by a few years. Instances of coal block de-allocation, cancelling of the 2G spectrum are pertinent. Such events are becoming more and more frequent, which even though highly beneficial for the industry in the long run, might push the development back a few years when seen in the perspective of investor’s investment horizon.
  • Sometimes, the challenges come from entirely unexpected events. Investors in the Shale Gas industry would never have seen the oil price slide coming, which has made many of the companies, bankrupt.

Above instances try to highlight the fact that there can be many factors, which may be completely out of control of HDFC Standard Life Insurance Company Limited that might impact its earnings growth rate over next 10 years and consequently, it might grow at a rate lower than 25%.

Similarly, there might be many factors, which might impact the valuation that the market might be willing to give to HDFC Standard Life Insurance Company Limited after 10 years:

  • The world might be falling apart again in 2026 (assuming 8-10 years of the bull-bear cycle)
  • India might be falling apart after nonperformance of intervening government/opposition for the next 10 years
  • We might elect a government, which deprioritizes private investment and promotes public spending as a model of the economy’s growth
  • Foreign investors (FII/FDI) might have found some other destination/country, which offers better potential than India
  • And not to forget, the government might tax long term capital gains from stock markets

There can be many more reasons to believe that the market situations might change and HDFC Standard Life Insurance Company Limited might not be able to command a PE ratio of 23 after 10 years.

It is evident that the business and market valuation assumptions might not sustain as discussed above in the calculation of the expected total return of 17% per annum, by holding shares of HDFC Standard Life Insurance Company Limited over 10 years.

Therefore, it becomes pertinent that we should do a sensitivity analysis of the total return that an investor would earn over varying situations of earnings growth rate that HDFC Standard Life Insurance Company Limited might achieve over next 10 years and the valuation level that market might be willing to assign its shares after 10 years.

The Probable Outcomes of High PE Ratio Investing:

We get the following table on doing the sensitivity analysis (with a constant dividend yield of 1.3% assumed earlier):

Sensitivity PE 50

The table reflects the precarious situation, which an investor puts herself into, by buying stocks at a high price of 50 times the earnings (PE ratio) in the first place.

  • If the annual sustained business/earnings growth rate achieved by HDFC Standard Life Insurance Company Limited over next 10 years is less than 15% (which in itself if a very good growth rate to achieve), then even if the market values it at a PE ratio of 25, the return of an investor would be 9%.
    • Moreover, if the market decides to value HDFC Standard Life Insurance Company Limited at a more reasonable PE ratio of 15 (assuming PEG ratio of 1), then the return to the investor would be mere 3%, which is less than the returns provided by a savings account (offers 4%, tax-free up to ₹10,000 per year and after that 2.8% assuming the highest tax rate of 30%).
  • Similarly, an investor can see that if the market decides to value HDFC Standard Life Insurance Company Limited at a PE ratio of 15 or lower, then even if it achieves spectacular growth rates of 25% per annum continuously for next 10 years, then its return would be modest (12% or lower)
  • And importantly, despite a healthy profitable growth rate of 10%, the investment might become loss-making for the investor if the market does not value HDFC Standard Life Insurance Company Limited at a PE ratio of about 20.

This scenario analysis clearly depicts that by initially purchasing the stock at a high PE ratio of 50, the investor has put many odds against herself. For her to make a respectable return and beat the return offered by fixed income instruments in India, her selected company must grow its earnings at a rate higher than 20% per annum and the market must value this company at a PE multiple of more than 20. Otherwise, she might be better off investing in a fixed instrument and have peace of mind while sleeping.

Such a situation reminds me of a runner, who has to keep running at the treadmill at a high speed of 20km/hour for 10 years and the selection committee (market) must recognize her efforts (assigning valuation levels), otherwise, it might not be a very happy ending. This becomes a very stressful situation for the runner and increases the chances of injury. The margin of error here is very low.

All this hard work and stress can be avoided if the investor can take care of one simple thing:

“Never overpay for a stock; however attractive the proposition is!”

Let’s assume the investor finds a company, which is hitherto unknown and growing at a good pace with sustained profitability, is conservatively financed and is available at a cheap valuation.

Low PE Ratio = Low Risk in Investing

Now, let us see how the total returns (including a dividend yield of 1.3% discussed earlier) to the investor would look like in different scenarios of earnings growth rate over next 10 years and the valuation levels assigned by the market at the end of 10 years:

Sensitivity PE 10

An investor would notice that if she does not overpay (i.e. buys at a PE ratio of 10 in this case), then even if the company achieves an earnings growth rate of 10% per annum over next 10 years and the market assigns the company a PE ratio of 10, she would make a total return of 11%, which is equal to returns offered by the most attractively priced creditable fixed return instruments in India.

Any scenario of a higher earnings growth rate over the next 10 years and any valuation level higher than PE ratio of 10, would bring positive surprises for the investor.

The earnings growth rate of 20% and PE ratio of 20, which was essential to beat the fixed income instruments earlier (when the initial purchase price was at PE ratio of 50), would now give the investor an annual total return of 30%!!

Examples of companies with High PE that produced low returns despite good business performance

When an investor analyses multiple companies that used to be at the peak of their valuations in the past, then she notices that many of these companies witnessed a decline in PE ratio despite improving business performance over the years.

Let’s look at the example of Just Dial Ltd, an investor notices that at one point of time during FY2015, the company used to trade at a PE ratio of 65. The market was very positive about the future of the company.

However, soon thereafter, the company started facing competition from the local search services of Google and other industry-specific vertical players like Zomato, Swiggy, Practo, Urban Company (UrbanClap) etc. As a result, the company’s OPM and the average price per paid listing declined. The market share/customer mindshare of the company also declined and the investing community started to doubt the competitive advantages of Just Dial Ltd.

As a result, during FY2015-FY2020, the PE ratio of the company declined from 66 to 7.

Just Dial Ltd Historical PE Ratio

This was despite an increase in sales of the company from ₹590 cr in FY2015 to ₹953 cr in FY2020 and an increase in net profit after tax from ₹139 cr in FY2015 to ₹272 cr in FY2020.

Just Dial Ltd Sales And Profit Trend FY2011 FY2020

Moreover, during FY2015-FY2020, Just Dial Ltd generated a free cash flow of ₹788 cr and gave dividends of ₹14 cr and four buybacks of ₹688 cr in FY2016, FY2018, FY2019 and FY2021.

This experience of the shareholders of Just Dial Ltd where an investment in the shares of the company at a high PE ratio of 66 did not generate a satisfactory return and the share price declined from ₹1,895 in August 2014 to about ₹380 in Sept 2020.

Just Dial Ltd Share Price History 2013 2020

Over last 6 years (FY2014-2020), Just Dial Ltd has retained earnings of about ₹1,118 cr whereas its market capitalization has declined by about ₹8,537 cr, which indicates a decline in the market value of about ₹7.64 for every ₹1 retained by the company that was not distributed to shareholders.

An investor may read our detailed analysis of Just Dial Ltd in the following article: Analysis: Just Dial Ltd

In other examples, an investor may look at Gillette India Ltd. During FY2014 to FY2018, the company increased its profits by 5x from ₹51 cr to ₹253 cr. Its net profit margin (NPM) increased from 3% in FY2014 to 15% in FY2018.

Gillette India Ltd Financial Performance

However, during this period, the PE ratio of Gillette India Ltd witnessed a decline from 203 to 51.

An investor may see another case of Page Industries Ltd. During FY2017-FY2019, the profits of the company increased by about 50% from ₹266 cr to ₹394 cr. During this period, the sales of the company increased by about 34% from ₹2,129 cr to ₹2,852 cr and the operating profit margin (OPM) of the company increased from 19% in FY2017 to 22% in FY2019.

Page Industries Ltd Financial Performance

However, during the same period, the PE ratio of Page Industries Ltd declined from the levels of 100 in 2017 to about 50 in 2019.

An investor would appreciate that when the stock price of any company runs up too much ahead of its fundamentals, then even the good business performance may not keep the sky-high valuations intact.

The Learning:

From the above analysis, an investor would appreciate that she can turn the odds of the stock market in her favour if she decides never to overpay for her stocks. She should avoid buying stocks at high PE ratio, however attractive the story may seem. Instead, she should spend time in finding out companies that are growing at a decent pace with sustained profitability, are conservatively financed and are yet to be recognized by the markets.

Read: Final Checklist for Buying Stocks

The hard work spent in finding out such hidden opportunities can tilt the odds in her favour. She can remain assured that even the modest sustained growth in the earnings and any recognition of her stock pick by established brokerage houses/institutional investors, would bring very pleasant rewards to her portfolio.

I always advise investors to focus more on the initial stock selection by finding good companies at an attractive price. It’s like a treasure hunt. However, once the investor has invested in such a company, then she can sleep peacefully over many future years. She can keep adding to her such stocks at every decline with the assurance that the game of the markets is now tilted in her favour.

No wonder, in markets, many renowned investors have stressed:

Never overpay for a stock. OR. Well begun, half done.

I would summarize it by saying that

“Buy good stocks cheap and get peaceful sleep”.

An investor might think that if a stock is fundamentally sound, then the market would have already recognized it and it would no longer be available at low PE ratio. The investor would not be wrong with this assumption. However, over time markets have proven that good quality stocks especially, the ones with low market capitalization, can remain hidden from institutional radar for prolonged periods of time. No wonder that entrepreneurial investors have been able to find attractive investment opportunities in the markets at cheap valuations.

On the contrary, the investor might also think that any stock would be available at a low PE ratio only when it has certain problems and it might deserve a low PE ratio. The investor is not entirely wrong in this assumption also as low PE segment is the area which contains almost entire junkyard of stock markets. However, it is this same low PE segment, where hidden opportunities exist, which have the potential of providing good returns to investors.

I believe that the common perception of high PE stocks being safe and low PE stocks being risky, is the very reason that entrepreneurial investors are able to find good investment opportunities in different market situations.

Moreover, an investor does not need to find a lot of such opportunities of fundamentally sound companies available at attractive prices. Experiences of notable investors have shown that a handful of such companies over the lifetime of the investor, are sufficient to create significant wealth for her. I believe that if an investor is able to one such stock every one or two years, then it is more than sufficient for getting good returns from stock markets.

To conclude, I believe that an investor should focus on finding fundamentally sound companies available at low PE ratio and avoid buying companies with high PE ratio. If an investor is able to follow this approach and find a handful of stocks over her lifetime, then she could expect to have the odds of the market turned in her favour. In this way, she can expect to generate significant wealth from stock markets without losing her peaceful sleep.

Is a high PE ratio for a company justified only due to its Industry?

Thanks, Dr Vijay for detail analysis. Here are my two cents:

Industry PE does give an idea about the relative position of the company within the industry; however, it can be deceptive at times, particularly when there is an excess optimism surrounds that industry, better known as fads.

Consider the year 2000. Wipro and Infosys were quoting at 100+ PE multiples. Due to high multiples, it became very easy for fly by night operators (companies) to join the bandwagon as it was easy to get a PE of 30 to 40. And even after 40 PE, it was still at a steep discount to the leading player, which attract even more investors to these stocks (they found the bargain!!). There were companies, which had hardly anything to do with IT, changed their names and added Infosys at the end and their share price got the sudden boost.

Consider the case of a company which is getting PE of 30. Traditionally, to get a PE of 30, you need a very strong competitive advantage, for example, ITC today (PE of 25). But, just because the company happens to be in IT, it was fetching higher multiples – considering Industry PE.

I think the company on its own need to stand investing merits. Industry PE can be a guiding factor in the evaluation, but relying too much on it can be hazardous to investment returns.

Thanks again,

Thanks for your feedback and valuable inputs!

You have highlighted very pertinent points with respect to the pitfalls of investment in high P/E ratios at the time of euphoric conditions. Other renowned investors have also cautioned the investors that most of the investment mistakes have happened when investors buy cheap quality at expensive prices during the height of the bull market.

We believe that Industry PE as a parameter is not relevant for investors.

Is Industry P/E Ratio Relevant to Investors?

We believe that investors should look at the fundamental characteristics of each company to determine whether any company deserves a particular PE ratio.

Author’s Response: 

Thanks for writing to me!

Whatever be the growth and profitability numbers, I would never be comfortable investing in a company at the P/E ratio of 69.95

It does not offer any margin of safety. In fact, it has a negative margin of safety.

However, there are investors in the stock market who follow different investing strategies and may invest in such a stock. I would like to delineate a belief that I hold about investing:

“There is no one path to success in stock market investing. Investors have made money in markets by following high P/E growth investing, low P/E value investing, mix of both, arbitrage, technical investing, large cap investing, mid/small cap investing and many other such approaches. Therefore, I believe that there is no single standard path to succeed/make money in markets. The path an investor should follow is the one she is convinced with and feels comfortable with.”

Therefore, I would advise that you do your own due diligence before making any investment decision.

  1. Earnings per share (EPS) of HDFC Standard Life Insurance Company Limited after 10 years: 3.93*(1.25)^10=₹36.60
    Sir, what is this calculation? Please explain. 3.93 is EPS and 10 years is the time. What is 1.25?

  2. Dear Dr sir,
    very thanks for detailed analysis about PE.
    Still, I have a query about price increase vs P/E ratio decline.
    In Gillette case, though the PE ratio declined from 204.4 to 51.8 during FY 2014-2018, the price was increased from Rs1897 to 4171 in the same period.
    Here still we have a good return, right?
    the same trend I have seen in page industry case also.

    • Hi Athinandhan,
      Thanks for writing to us!
      The article highlights the risks about investing in high PE stocks and the probability that if the valuations run very high, then in future the PE ratio may decline and the returns may be impacted.
      As another example, you may read the case of Just Dial Ltd where the PE ratio declined from 90 to 7 and the share price declined from ₹1,895/- to ₹380. Read it here: https://www.drvijaymalik.com/2020/09/analysis-just-dial-ltd.html
      Nevertheless, if an investor is convinced that despite a decline in PE ratio, in the absolute terms, she would make a good return, then she may invest at a high PE ratio. At the end of the day, investing is all about the conviction of the investor.
      All the best for your investing journey!
