analyzing investmentsWhen it comes to buying stocks, one of the most important pieces of advice is to not overpay.  The price you pay for the companies you buy can make or break your investment.  Even a bad company could turn out to be a great investment if you buy it at a great price while even the greatest of companies may turn out to be an awful investment if you invest when it is priced way too high.

Typically I have new capital ready to invest each month.  When I am ready to decide what company I would like to purchase, I have a 2 step process.  First I review the companies that make up my stock watch list as these are the companies I have decided I would like to own.  I look over my watch list to get a rough idea of which companies might be currently trading at the lowest valuation.  Once I have an idea of a few companies from my list that I believe are currently trading at low or fair values I will do a deeper stock analysis of those companies and calculate out future expected returns of a current investment.  Once I’ve gone through this process I then decide which company or which companies I will currently buy depending on how much current cash I have available for a purchase.

A question that sometimes gets asked is how I determine which stocks I believe to currently be trading at decent values that I will then look further into.  The answer is pretty simple and the exercise of narrowing down my list to a few companies that I believe to be the best current valuation really only takes a few minutes.  It helps to be very familiar with the stocks on your watch list but even if you aren’t, it isn’t that long of a process.

Compare the Current P/E Ratio to Historical Ratios

The P/E ratio, or Price to Earnings Ratio, is one of the quickest ways to get an idea of the current valuation a company is trading at.  There are a couple P/E ratios you can calculate and consider.  The P/E ratio I use is taking the current stock price divided by the last annual reported earnings per share amount.  For example if a stock currently trades at $25/share and its last reported annual EPS was $2.10 then the P/E would be 11.9 (25/2.1 = 11.9).  This number can usually be found on most financial websites that report stock market statistics.

It is important to remember that different companies are going to trade at different P/E’s for a variety of reasons.  Companies that grow their earnings at a higher growth rate will typically demand a higher stock price and thus a higher P/E ratio.  Sometimes a company can demand a higher P/E ratio because of its great reputation for being a great company.  On the same token, companies may trade at a lower P/E because there are questions about its future growth or maybe they had a recent negative event.  For this reason, I believe it is important to compare the current P/E that a company is trading at with its historical average P/E ratios.

I get an idea of the historical P/E ranges from the S&P stock reports that I am able to get through my broker online.  Check if your broker offers some report like this with historical information or if not you can buy the annual book put out by S&P with the stock reports for all the S&P 500 companies at Amazon Standard and Poors 500 Guide 2013.  Another good resource is the Value Line stock sheets which you may find at your local library.

For an example I will look at 3 different stocks and tell you what I think of them currently.

  1. Procter & Gamble (PG) – Looking at the S&P stock sheet for PG, I see the 2012 EPS was $3.54.  PG closed on January 17, 2013 with a stock price of $69.67.  This gives PG a P/E ratio of 19.68 (69.67/3.54).  Looking at the historical P/E’s on the S&P stock sheet over the past 10 years I can see that PG traded with a high P/E of 27 back in 2003 and a low P/E of 11 back in 2010.  Before the recession of 2008, PG’s P/E ratios low end was usually around 19 or 20.  Since 2008 until last year you had opportunities to get PG with a P/E down in the low teens.  Based on this information I would say that PG is probably trading at a fair valuation.  Definitely not undervalued but if the stock is viewed as it was before the recession then getting it at a P/E under 20 might be the best you’re going to do.  If you’re interested in this company you may want to look further into it.
  2. McDonald’s (MCD) – For MCD the 2011 EPS was $5.22.  The 2012 results are not yet announced.  MCD closed on January 17, 2013 with a stock price of $91.76.  This gives a P/E ratio of 17.6 (91.76/5.22).  Looking at historical P/E’s I see that MCD traded with a range of 12 to 20.  Actually back in 2002 the high P/E was 40 but I usually will throw out any outliers.  So with that information I would probably say MCD is towards the higher range.  I don’t necessarily think it is over valued but it is on the high side of being fair valued.
  3. Aflac (AFL) – Aflac had a 2011 EPS of $6.32.  AFL closed on January 17, 2013 with a stock price of $51.44 giving it a current P/E of 8.1 (51.44/6.32).  Looking at historical P/E’s I see that AFL traded with a range of 8 to 20.  Based on this AFL is towards the bottom of its range and I would consider it to be undervalued.  Remember though that there is probably some reason AFL is being valued low and you need to do a complete analysis before jumping into any investment.

So that is how I would get a quick idea of valuation using P/E ratios.  If the above group were the only companies I was interested in then I would choose Aflac to look further into.  I would analyze the company and calculate expected future returns before making an investment.

Besides P/E ratios I also like to look at one other metric to help get an idea of valuation.

Comparing the Earnings Yield to Long Term Treasury Rates

Along with looking over the companies P/E ratios another metric I like to look at is the company’s earnings yield and compare that to the current 30 year US treasury bond interest rate.  The earnings yield is actually the inverse of the P/E ratio.  It is calculated by taking the EPS of the company and dividing by the current market price.  This will give you a percentage.  For example a stock trading at $25 a share with EPS of $2.10 will have an earnings yield of 8.4%.  I compare this to the current treasury rate found on Bloomberg which is currently at 3%.  The idea is that I can buy a treasury bond and safely earn 3% in interest on my investment.  The other option is I can buy the stock and earn a yield of 8.4%.  However, there is more risk in the stock but there is also chance for the amount I’m earning to grow over time which will not happen with the bond.  So I like the earnings yield to be higher than the long term treasury yield and as with every stock I’m interested in I make sure they are growing their EPS over time.  Let’s look at our examples again.

  1. Procter & Gamble (PG) – PG’s current earnings yield is 5.09% (3.54/69.67).  This is higher than the 3% I could earn from a treasury bond.  In the current low yield environment, PG’s stock looks like it would be a decent value.  I would also want to make sure that the company is growing earnings per share over time.
  2. McDonald’s (MCD) – MCD has a current earnings yield of 5.69% (5.22/91.76).  This gives us a very similar result as PG.
  3. Aflac (AFL) – Aflac has a current earnings yield of 12.29%.  Compared to the treasury rate this looks like a great deal.

As you can probably tell, the earnings yield is going to lead us to the same companies of interest as we would get to by looking at P/E ratios.  The reason looking at earnings yield is important is so that you can compare it to current treasury rates.  For example, a company with a P/E of 20 would have an earnings yield of 5%.  This is not a bad deal in today’s interest rate environment as long as I conclude this company’s earnings are fairly consistent and growing over time.  However, if the 30 year treasury rate was higher, say 6%, then I would want to consider buying treasury bonds instead.  They would offer a higher initial rate of return that is safer.

The lesson is that the higher the 30 year treasury rate, the lower we want to pay for stocks.  Generally in higher yielding environments stocks will trade at lower valuations but this doesn’t always seem to be the case.  For example, during the dot com bubble some investors were willing to pay outrageous prices for stocks.  They were buying stocks with earnings yields of 2.5% or lower when the treasury rate was much higher.  These investors would have been much better off purchasing treasury bonds instead at that time or at the least not investing in these overvalued stocks.  These overvalued stocks eventually plummeted in price or saw flat returns over the next decade.


These are the two ways I’ll do a quick valuation of whether I think a stock is fair, under or over valued.  Usually I rely more on the P/E ratios rather than earnings yield but I think both can be valuable to pay attention to.  It is important to remember that this is just the first step in the investing process.  Next it is important to do a complete analysis and estimation of future returns before actually making the investment.  Just because a stock is trading with the lowest P/E or the highest earnings yield does not mean it is the best investment to make.  Check the news on the company.  Look over the financial data.  There may be a reason why the market is valuing that company lower than other companies in the stock market.

8 Responses to 2 Quick Ways to Get an Idea of a Companies Valuation

  1. I need to do a better job of getting a centralized location for my stock analysis and to get a better watch list together. There’s several companies that I know I’d like but I’ve just never compiled them into one list. Chalk this up to laziness right now.

    • Dan Mac says:

      JC, I think a watchlist can be a valuable tool for many investors. Honestly my watchlist isn’t up to date and that is one thing I want to work on coming up soon. There are some stocks on there that I’m no longer interested in and others that I am interested in that need to be added to the list. I think my ultimate goal is to come up with a list of around 30 companies that I can keep better tabs on going forward and eventually have a well diversified portfolio made up mostly of just those companies.

      My ultimate idea would be to have the watch list completed with those 30 or so companies and then like I mention in the article every time I have money ready to invest, do a quick review of the watch list to see which companies I believe are at that time trading at decent valuations and then looking further into those companies.

    Here’s a worksheet I do that whenever I want to know if a stock is worth buying. (I benefit in no way if you use this.) I put this worksheet together after doing exactly what you start this article with – overpaying. Takes about 15 minutes a stock. I do it every year on each stock I own, also. There are links on the worksheet to all needed info that is available free. Hope it’s helpful.

    • Dan Mac says:

      Thanks for the link klbeck. I’ll have to check out your spreadsheets!

  3. Jean-Louis says:

    Thank you Dan for this article; Helps a lot, really. What about looking for a significant pullback (e.g. -5%) in a stock’s price or using the 52-week high and low as complementary information for deciding about buying a dividend stock among the watchlist?


    • Dan Mac says:

      Jean-Louis, I think looking at pullbacks or comparing current price to 52 week high and lows can also be useful information. Quite often I look over the stocks on my watch list and how they performed the past day or week. Many times if I see a significant pullback I look into the possibility of taking advantage of the pullback. It is important to make sure you still do your due diligence though and make sure it still looks like a good investment. Also, I often look at stocks compared to their 52 week lows and highs for a reference. However it is still important to do a complete analysis in all cases as to whether you should be buying at the current time or not.

  4. Great concepts Dan! As you said they can be done very easily and very quickly by a novice investor. I believe the hardest problem with this strategy is having enough confidence and experience to know you are investing for the long term and buy when stocks are at their low points.

    • Dan Mac says:

      Thanks Marvin, I think it can be very challenging sticking to any investment plan when the market fluctuates as much as it does. When buying stocks I think it is important for us to lay down our goals and remember that while we own the stocks there is a strong likelihood that we will see large decreases as much as 25-50% during some markets. Of course those times that scare us the most turn out to be the best buying opportunities and over the long term I fully believe stocks will fare nicely for their owners.
