Ellen asked;
Does it matter whether the value of my stock investments increases because of earnings or increase in value? If so, is there a rough and ready way for me to tell how much of the increase is due to earnings and how much due to price increase?
The simple answers to these two questions are 'No' and 'No'. Let me explain...
First off, you must understand that there is no value without earnings. Any increase in stock value that one might think is unrelated to earnings is a misnomer because it always comes back to earnings and earnings growth. Stock prices will always reflect investor sentiment about the future over the short term. Over the long term a stock's value should come back to reflect the true measure of a company's success, which is earnings per share (EPS). Broken down to it's bare bones, the only thing that really matters to a stock's value is earnings per share, however obviously several other factors will dramatically influence the price. If a food manufacturer just earned a great EPS number for the year but lost two major contracts due to a deadly contaminant in their product, the high EPS will matter very little as the stock is sold off hard.
For example, let's say Gusher Oil & Gas earned $4.00 per share in 2009. You might think the stock should trade for at least $32 per share or so (8x earnings), if the firm was in decent shape and was expected to grow earnings at a moderate pace. In reality Gusher could trade at $16 per share if oil prices are expected to plummet and Gusher had taken on too much high interest debt. On the flip side, Gusher could trade at $80 per share if they just discovered a new oil deposit and oil was expected to rise dramatically in the short term.
A good way to understand why stocks are priced the way they are, and why they move the way they do is to understand the sum of investor's thoughts about the company's future earnings growth potential. This is a complicated mish mash of predictions, anticipated industry trends, past performance, and expectations.
At the end of the day every stock price is a guess at future earnings growth.
