Valuing Stocks - Absolute or Intrinsic Valuation

The two basic method of valuing stocks are;

  • Relative valuation
  • Absolute or Intrinsic valuation
Usually, absolute value is estimated by calculating the present value of the company's future free cash flows (cash flow minus capital spending).

The present value of that future-income stream is the theoretically correct value of the stock.

This method has its own difficulties and is less frequently used, but absolute value deserves a place in every investor's arsenal of valuation tools.

Calculating the absolute value of a stock isn't easy.  It is tough to forecast:
  • how fast a company's free cash flow will grow, 
  • how long they'll grow, and 
  • at what rate they should be discounted back to the present.  

We estimate stocks's absolute values by inputting our estimates of a company's growth rate, profitability, and the efficiency with which it uses its assets into a discounted cash flow model.  The result is an analyst-driven estimate of a stock's fair value in absolute terms.

In an imperfect world, opting for the much easier - if less pure - method of relative valuation often makes sense.  

However, when the companies you are using as your benchmark are themselves mis-priced, relative valuation can lead you astray; without a reliable measurement tool, your measurements will be off.  That last point is crucial.

If the S&P 500, for example, is trading at a P/E ratio that is very high by historical standards, using it as a benchmark can be hazardous.  

A stock can appear much cheaper than the overall market and still be quite expensive in absolute terms.  So what's an investor to do?  

Unfortunately, there aren't any easy answers.  

The best way to approach stock valuation is by using many different methods, the same way you would if you were valuing a used car or a house.

Checking out what similar houses in a neighbourhood have sold for is akin to relative valuation, and walking through a house you're interested in - looking at the construction and quality of materials - is similar to intrinsic valuation.  

A judicious mix of both methods will serve you well.



Common Valuation Ratios

Let's look at the ways in which a stock's price compared with the value of the underlying company can be represented.

Valuations are usually expressed as the ratio of a company's share price to an aspect of its financial performance, such as:

  • price/earnings (P/E), 
  • price/sales (P/S), 
  • price/book value (P/B),
  • price/cash flow (P/CF), or 
  • price/estimated growth rate (P/EG)
We know that a stock's value is a combination of the company's present condition and its future prospects, and it is usually measured by a series of ratios.

But how do we decide if that value is too high, too low, or just right?

This is where things can get tricky, because valuing stocks is sometimes more an art than a science.  

That's why it is not uncommon for two analysts to look at the same company and come up with different conclusions.

Valuing Stocks - What Is a Stock's Value?

The value of most stocks is a combination of the current value of the company and the value of the profits it will make in the future.

In general, the more growth the market expects from a company, the more the company's market value will owe to expected future profits.  

Take online bookseller YY, for example.  By most measures, company YY has little or no current value; it has only minuscule book value and is gushing red ink.  Liquidating company YY would leave its investors with zilch.  But the market thinks the company's future profit potential is so bright that it has pinned a multibillion-dollar worth (the company's market capitalization) on the stock.

Another way to think of a stock's value is that a company's stock price consists of a combination of what you are paying for the company's current level of profitability and what you're paying for its earnings growth.

Since company YY is far from profitable then,  the stock price is based almost entirely on expectations of future growth.  That is one reason company YY's stock is so volatile.

As those expectations rise and fall, so does the price of its stock.

In comparison, the stock price of another stock XX largely reflects the company's current value, not its future growth.  Company XX is quite profitable, but no one expects it to grow terribly fast.

Valuing Stocks

Valuing a stock is a lot like buying a car.

There are lots of great cars out there, but the sticker price may be more than the actual worth of the car.   Some manufacturers command a premium price because their cars have a certain cachet, not because their cars are necessarily more reliable or of better quality than others on the market.

It is the same thing with stocks.

Some stocks are valued much more richly than others because they are hot or popular with investors, not because the companies are more profitable or have better growth prospects,

The ability to decide whether a company's stock price accurately reflects its performance is the heart of stock valuation.
