The whale race

what copying each whale's filings returned, $1 at your chosen start
What a copycat would have made: buying each filed book, bought at every filing deadline, rebalanced quarterly. Price returns, dividends excluded on all lines. Copycat of public filings, not the fund's actual performance. * = under 80% of the book priceable, read loosely.
