Buffett Criteria (Buffettology)

Buys on the screenable Buffett criteria from Mary Buffett’s “Buffettology”: the company earns at least 15 percent on its equity, carries little debt (at most half of equity), keeps at least 10 percent of revenue as operating profit, has posted positive earnings per share in each of the last six quarters — the two most recent ones each above the same quarter a year earlier, so that seasonality does not decide the outcome — and had free cash left over across the last four quarters. What the numbers cannot show is the moat, the durable competitive advantage; that stays a matter of analysis. Only shares our own deep-dive analysis rates green are bought — yellow or no analysis at all is not enough. New positions are added once a month; a stock is sold as soon as it no longer meets one of these conditions or is no longer rated green.
