Well good luck. It's just too easy to fool your self in an up market. It would be much more interesting to see your results in a down or sideways market.

A fool would judge their algorithm based on ANY single year's performance--up down or sideways. Moving averages over 5 or 10 years are what matter.

Check out Berkshire Hathaway's performance. There are plenty of years they have UNDER performed. But they are doing OK.

My understanding is berkshire does a lot more than just buy stocks. They buy companies and actively improve/invest/streamline them to be more profitable. This will obviously increase the value of said company and make them money. Most retail investors can't do this, so it's pointless to compare the two.
