PER-SHARE EARNINGS: How Warren tells the winners from the losers

PER-SHARE EARNINGS: How WARREN TELLS THE WINNERS FROM THE LOSERS

Per-share earnings are the net earnings of the company on a per-share basis for the time period in question. This is a big number in the world of investing because, as a rule, the more a company earns per share the higher its stock price is. To determine the company's per-share earnings we take the amount of net income the company earned and divide it by the number of shares it has outstanding. As an example: If a company had net earnings of $10 million for the year, and it has one million shares outstanding, it would have per-share earnings for the year of $10 a share.

While no one yearly per-share figure can be used to identify a company with a durable competitive advantage, a per-share earnings figure for a ten-year period can give us a very clear picture of whether the company has a long-term competitive advantage working in its favor. What Warren looks for is a per-share earning picture over a ten-year period that shows consistency and an upward trend.

 Something that looks like this:


08
$2.95
07
$2.68
06
$2.37
05
$2.17
04
$2.06
03
$1.95
02
$1.65
01
$1.60
00
$1.48
99
$1.30
98
$1.42


This shows Warren that the company has consistent earnings with a long-term upward trend---an excellent sign that the company in question has some kind of long-term competitive advantage working in its favor. Consistent earnings are usually a sign that the company is selling a product or mix of products that don't need to go through the expensive process of change. The upward trend in earnings means that the company's economics are strong enough to allow it either to make the expenditures to increase market share through advertising or expansion, or to use financial engineering like stock buybacks.

The companies that Warren stays away from have an erratic earnings picture that looks like this:
                       

08
$2.50
07
         $(0.45) loss
06
$3.89
05
         $(6.05) loss
04
$6.39
03
$5.03
02
$3.35
01
$1.77
00
$6.68
99
$8.53
98
$5.24


This shows a downward trend, punctuated by losses, which tells Warren that this company is in a fiercely competitive industry prone to booms and busts. The booms show up when demand is greater than supply, but when demand is great, the company increases production to meet demand, which increases costs and eventually leads to an excess of supply in the industry. Excess leads to falling prices, which means that the company loses money until the next boom comes along. There are thousands of companies like this, and the wild price swings in shares, caused by each company's erratic earnings, create the illusion of buying opportunities for traditional value investors. But what they are really buying is a long, slow boat ride to investor nowhere.
