Basilea Pharmaceutica  (XSWX:BSLN) Earnings per Share (Diluted) Explanation

Earnings Per Share (EPS) is the single most important variable used by Wall Street in determining the earnings power of a company. But investors need to be aware that Earnings per Share can be easily manipulated by adjusting depreciation and amortization rate or non-recurring items. That's why GuruFocus lists EPS without NRI, which better reflects the company's underlying performance.


Be Aware

Compared with Earnings per share, a company's cash flow is better indicator of the company's earnings power.

If a company's earnings per share is less than cash flow per share over long term, investors need to be cautious and find out why.
