How to determine fair market value of a stock?

April 7, 2006 8:58 AM

Seeking calculation or calculator for easier determination of legitimate share price for companies.

Any one have any ideas or know of even a web based calculator so I can better determine a fair market value of a share? In other words, if a share is over valued or under valued based upon some standard input types.

I recognize there are inherent difficulties in such a simplified system - but I am fairly sure there are ways to determine with some confidence factor given a balance sheet. I am not looking for a sure thing, just a starting point.

I think you need to be disabused of your notions about valuation, but since that wasn't the question you asked and there are hundrends upon hundreds of books available on the subject, I'll restrain myself.

I don't know about any calculators, but I'm not sure why you'd need one. Do you already know which balance sheet items or other metrics you'd like to test and what benchmarks you're aiming for? If it's just a matter of figuring out how to do certain calculations, I could probably answer those questions. Most could be made into simple Excel models.

Also, while again this isn't a direct answer to your question, MSN Money, among others, have stock screens that allow you to find companies that meet certain criteria (P/E multiples, profit margins, growth rates, etc).

Billions have been poured into this question. Literally. Thousands of people everyday are spending their entire working day on these questions. If you can get it off of a balance sheet I'd patent that process immediately.

Best answer: The only way to determine fair market value of a stock is to ask the market what it will give you for it. However, this looks like a good introduction to the principles investors use to value a company based on its financial reports. One guy I know of likes to calculate several measures of value (at least six IIRC), throw out the highest and the lowest, and take the mean of the remaining ones.

My business planning professor has repeatedly emphasized the point that there is no "correct" value for any company. He would, however, approve of kindall's friend's method of determining several values based upon different methods and taking a mean of a few in the middle.

Even relatively simple, traditional metrics like P/E ratio have become hugely skewed and strange.

Examples: PCLN and on the other end of the spectrum GOOG.

To further emphasize kindall's point, take a look at the proxy statement on the Procter & Gamble / Gilette merger. The section called "Opinions of the Financial Advisors" includes three "fairness opinions" given by the advising investment banks, Goldman Sachs, UBS and Merrill Lynch. These analyses should be taken with a grain of salt* and their purpose is not the same as yours, but it provides a good example of various valuation methodologies used and that it is more of an art than a science.


*Fairness opinions should be viewed sceptically, of course. Merrill Lynch, for example, was paid $1.5 million for their fairness opinion (and $30 million more for their advisory work). But, the delivery of the opinion will protect the directors of PG from lawsuits, so it is taken very seriously.
