Investors repeatedly jump ship on a good strategy just because it hasn't worked so well lately, and, almost invariably, abandon it at precisely the wrong time.

We invest in undervalued companies that exhibit strong fundamentals, above-market dividend yields and historic earnings growth, which our analysis indicates will persist. Our strategy is to own strong, fundamentally sound companies and to avoid speculative stocks or potential bankruptcies.

Psychology is probably the most important factor in the market - and one that is least understood.

I paraphrase Lord Rothschild: ‘The time to buy is when there's blood on the streets.'

Patience is a crucial but rare investment commodity.

Favored stocks underperform the market, while out-of-favor companies outperform the market, but the reappraisal often happens slowly, even glacially.

I buy stocks when they are battered. I am strict with my discipline. I always buy stocks with low price-earnings ratios, low price-to-book value ratios and higher-than-average yield. Academic studies have shown that a strategy of buying out-of-favor stocks with low P/E, price-to-book and price-to-cash flow ratios outperforms the market pretty consistently over long periods of time.
