A company may buy back shares or issue shares in any fiscal period. If a company buys back shares, we should observe that the total number of shares decline. If the company issues new shares, the number of shares outstanding increases.
Usually the presence of treasury shares and a history of buyback are good indicators that company has competitive advantage. But studies have shown that companies usually buy back at wrong time. Buying back shares below its intrinsic value increases value for remaining shareholders. Buying back overvalued shares destroys value for existing shareholders.

Warren Buffett looks for consistency and upward long term trend. Because of share repurchase it is possible for net earnings trend to differ from EPS trend. He preferred net income over EPS. The companies with durable competitive advantage companies report higher % net earnings to total revenues.
Important: If a company is showing net earnings history greater than 20% on total revenues, it is probably benefiting from a long term competitive advantage.
If net earnings is less than 10%, likely to be in a highly competitive business.
