Billionaire investor Mario Gabelli has been richly rewarded for his faith in Warren Buffett’s Berkshire Hathaway.

The Gamco Investors CEO snapped up more than 200 of Berkshire’s “A” shares for two of his funds in the late 1980s, he told CNBC this week. Gabelli paid an average of $US6,000 ($7,697) for the shares, which now change┬áhands at north of $US370,000 ($474,631) each.

Overall, Gabelli paid about $US1.3 ($2) million for Berkshire stock worth $US83 ($106) million as of Tuesday’s close – an astounding 6,200% gain.

The Gabelli Asset Fund and Gabelli Equity Trust owned a total of 218 Berkshire “A” shares worth $US76 ($97) million as of December 31, SEC filings show. Berkshire’s stock price has climbed about 9% to record levels since then, boosting the value of Gabelli’s stake to fresh highs.

Gabelli’s outsized gain required not only the foresight to back Buffett’s conglomerate more than 30 years ago, but the discipline not to cash out his stake.

Those traits aren’t too surprising, given Gabelli sums up his investing approach on Twitter as “Graham & Dodd + Buffett = Gabelli.” In other words, he sees himself as a mix of Buffett and two of the Berkshire’s chief’s mentors, Benjamin Graham and David Dodd.
