What is Price to Earning Ratio: Interpreting P/E Ratio of a stock

P/E ratio is a very popular term amongst stock investors. Anybody who is considering investing in stocks does usually find out the P/E ratio of the stocks he is researching. At the same time, strange as it may sound, very few people are able to use the P/E ratio well in their investment decisions. In this post, we will try to understand what P/E Ratio means and how it can help an investor make sound investment decisions.

Calculating PE Ratio:

First things first, let’s understand how we arrive at the P/E ratio of a stock. The formula is

P/E Ratio = Stock Price/ Earning Per Share

Let’s say that a stock has annual Earning per Share of $10, and is trading at $120. In this case, the P/E ratio will be 12. A conservative investor will prefer using earnings from the previous four quarters, while calculating P/E ratio. In fact you can choose to take an average of last 3-5 years of annual earnings, if you really want to act like a true value investor. Averaging helps remove aberrations from the earnings of a stock. However, many analysts consider expected earnings for the next four quarters. A flaw, that too a major one, with this approach is that expected earnings are ‘EXPECTED’ earnings. They can change faster than your mood. And then, everybody has different expectations.

Interpreting PE Ratio:

Simply put, in the example above, assuming that the stock returns the same level of earnings year after year, you should get back your money in 12 years. If you reverse the PE ratio, you will get the Earning Yield of the stock. Earning Yield is a measure of the return from a stock. In this example, you are getting a return of 100/12 or 8.3% per annum on your investment. Remember that all earnings of a company belong to shareholders. Irrespective of what dividend is being paid out to shareholders in the short term, ultimately all the earnings should flow back to the shareholders. Earning yield is a good measure to consider if you are thinking about choosing between other investment options and stocks for investing your money.

P/E ratio gives you an idea of what the market is willing to pay for the company’s earnings. By relating share prices to actual profits, the P/E ratio highlights the connection between the price and recent company performance. If prices get higher and profits too move up, the ratio stays the same. The ratio moves only when price and profits become disconnected.

For this reason, when the P/E ratio is higher or lower than normal we know that recent profit levels are no longer the main factor in pricing. This might be because market is expecting a change – a change in the performance levels of the company in either direction going forward or a change in the market sentiment. You must make a note of these changes.

A higher P/E means that the market is willing to pay more for a stock compared to another stock with a lower P/E. An interpretation of a high P/E could be that the stock is overpriced. On the other hand, this could also mean that the market has high hopes from the stock in future, and it is factoring in the future earnings of the stock in its current price. Similarly, a low P/E may indicate a stock with low expectations from the market or it could mean an undervalued stock that has been overlooked by the market. Value investors hunt this kind of undervalued stock. Note, however, just because a stock is trading at a low P/E does not mean you should buy it. If it is an undervalued stock, it might be a good bargain. However, if it is a stock, which is not expected to do well in future, you may want to do a little research before you buy it.

You should, however, never consider P/E ratio in isolation. It’s a good measure if you use it for comparison between competitors or with the market or with the same company at different points in time. However, if you choose a telecom company over a steel company based on the difference in their P/E ratio, it may not be a very fruitful exercise.

Different types of P/E Ratios:

Many analysts will use different types of P/E ratios resulting in utter confusion. These can be trailing P/E ratio based on earnings of the last four quarters or forward P/E ratio based on expected earnings of the next four quarters. Using past earnings might not be a great indicator of the future earnings of a stock. However, in reality, past earnings have been better indicators of the future earnings of a stock than the earning forecasts made by stock analyst. It’s not easy to manipulate the value of trailing P/E ratio, as there is no guesswork or wishful thinking involved in calculating it, which is why value investors prefer using trailing P/E while making their investment decisions.

I hope the above post is able to give you a basic understanding of the P/E ratio. The next question in your mind could be what the right P/E for a stock is. I will answer this question in my next post. Stay tuned.

Fundamental Analysis for Investing in Stocks

There are many investment styles- technical, fundamental, growth investing, value investing, speculating, etc. Fundamental Analysis, as the term suggests, is about the fundamentals of a stock. It focuses on understanding the prospects of the business underlying the stock by analyzing the financials of a company, qualitative factors like management quality and economic factors affecting an economy and industry. The aim of Fundamental Analysis is to uncover the intrinsic value of a stock.

Technical analysis is another type of investment analysis that focuses on the momentum of a stock and doesn’t bother too much with the underlying business. Price history of a stock, current momentum, liquidity in the market, investor sentiments, etc are the key factors in technical analysis. A long-term investor should never bother with technical analysis, as short-term trends do not matter in the long run.

Many investors depend on a combination of technical analysis and fundamental analysis for making decisions regarding stock investment. If you are a long-term investor, and are willing to put in some effort in order to make a decent amount of profit from investing in stocks, you will do a world of good to yourself by doing some fundamental analysis before you invest any money.

To be a good fundamental analyst, one needs to master the art of interpreting financial statements. Fundamental analysis starts with analysis of financial statements and various ratios. It takes into account operating cash flows, earning per share, Price to earning ratio, capital structure, earning estimates, current ratio, debt to equity ratio, etc. A fundamental analyst tries to derive the value of a business based on various valuation models. Some of these models are discounted cash flow model and dividend discount model. Apart from analyzing the past financial data of a business, most models depend on assumptions regarding the future growth and risk associated with the business. This factor makes even fundamental analysis very subjective, leading to divergent views about the value of stock in the eyes of different analysts. For knowing more on these stock evaluation models, you can google the terms highlighted above.

Value investing is not very different from fundamental analysis. If you go through the lessons on how to select stocks, you would have covered a major part of fundamental analysis.

It is very difficult to cover the topic of fundamental analysis in one post. Suffice to say that fundamental analysis involves understanding the businesses behind stocks and presents an investor with opportunities to invest in undervalued stocks.

Value Investing: How to find a value stock

Whenever somebody talks about ‘Growth Stocks’, he or she also talks about ‘ Value Stocks’ in the same breath as both these types of stocks are considered two primary types of investment worthy stocks. In my last post, I talked about ‘Growth Stocks’. It’s but natural that this post is about Value Stocks and the philosophy behind picking a value stock i.e. Value Investing.

My whole blog is primarily about value investing because this is perhaps the most robust and least risky way of investing in stock marekt. Legendary investment guru Benjamin Graham and his equally legendary disciple Warren Buffett have made ‘Value Investing’ very popular amongst investors. Practising value investing requires some amount of effort and patience from an investor. Which is why though value investing is a much talked about term, it’s not really widely practiced despite its obvious advantages.

The concept of value investing revolves around investing in stocks that are trading at a price levels lower than their ‘intrinsic value’ or their real worth. The fundamental thing to remember in value investing is that when you are buying a stock of a company, you are essentially investing in the business of the company. You should buy a stock only if you believe that the business behind the stock will be able to give you good returns on your investment. Before investing in its stock, you should assess the business fundamentals, earning stability and growth, financial structure, dividend record and the management quality of the company. A value investors pays special attention to the principle of margin of safety before investing in a stock. A company can be running a great business, but if its stock is priced at a higher level than its intrinsic value, it’s not worth investing in it. Similarly, a company might be in under distress and may have lost the confidence of investors for a temporary period; but it could be a great buy if the intrinsic value of the stock is much higher compared to the current stock price after taking into account the risk factors.

For a full understanding of how you should go about selecting a value stock, you can read the series of posts on ‘How to Select a Stock for Investing’ on my blog as given below:

A value investor doesn’t pay attention to trends in the stock market. There are various reasons why a stock price moves in the stock market in the short term. However, in the long run, it is the fundamentals of the company that drive the stock price. If you have done your analysis thoroughly following the value investing philosophy and you are a long-term investor, the chances of your investment going awry are almost zero.

How to select a stock- Part VII- Finding the right price of a stock

In this post, we will learn about how to find the right price for a stock. Many people confuse good companies with a good stock. If they like a company’s business model, they purchase its stock without any consideration of the price it is trading at. What matters more in investment is that you have bought a stock at the right price. If you have bought stocks of a great company at a very high price level, it may not turn out to be a great investment. On the contrary, if you have bought stocks of a good company at a good price level (cheap), you may get good return on your investment. It’s important to buy cheap.

A stock price is supposedly an indicator of net present value of future earnings for the stock on per share basis. This is also called the intrinsic value of a stock. However, the problem with this concept is that one needs to predict the future to be able to arrive at the right stock price. Millions of people have tried predicting future in the past, but rarely have we seen anybody doing so accurately. This very concept leads to a lot of investing mistakes by millions of people. A lot of analysts get into the game of predicting future earnings through various esoteric mathematical formulae. Nobody gets it right!

A good approach for stock selection could be following what legendary Investment Guru Benjamin Graham advised- follow the principles of ‘margin of safety’ and ‘diversification’.

The margin of safety concept says what you are buying should be worth more than what you are paying by a wide margin. Such a simple thing, but it’s really difficult to act on it considering the problem in assessing the value of a stock. Graham says you shouldn’t get into the business of predicting the future; instead, use the past performance to assess the ability of the company to keep producing decent earnings in future. Hence, if the company has a current earning of about 12% of the stock price (i.e. a PE ratio of 8), and meets all our criteria of selection as mentioned in my previous posts, and risk free return (of a 10-year government bond) is 6%, you have a good margin of safety in the stock. There is no general formula for all industries. However, in most of the cases, the PE ratio should not go beyond 15. The higher the PE ratio, the more future growth dependent your return on the stock becomes. Never buy a stock if you believe it is fully priced even if it is of the best performing company.

Diversification is linked with the concept of margin of safety. Let me explain. If you are playing dart, and you are good at it; what are your chances of hitting bulls eye once if you have only once dart? What if you have ten darts? Of course, you will have much better chances of hitting Bull’s Eye at least once if you have ten darts. Do you understand the difference? If you have margin of safety in your favor, your chances of making good returns or at least not incurring loss in a portfolio of diversified stocks becomes pretty high. However, there is a caution here. Diversification will work to your favor if you have diversified in stocks with good margin of safety. It will hurt you badly if you have bought all losers. Diversification in overpriced stocks will ensure that you most likely incur loss on your investment. So, be careful. Don’t buy costly stocks. Always maintain a diversified portfolio of good stocks bought with a margin of safety.

With this, the series on ‘how to select stocks for investing’ ends. I hope I have been able to give you a few basic guidelines on how to go about picking stocks for investment. I must add that these are indicative guidelines and by no means exhaustive. You will do well if you use these guidelines along with your own research and experience backed by some sound reasoning.
