It’s nearly difficult to ignore previous performance when choosing a mutual fund to purchase. Undoubtedly, past performance is often the very first thing a mutual fund will certainly expose about itself.

‘The expression ‘previous performance isn’t an indicator of future results’ (or some variation thereof) can be found in the small print of many mutual fund literature,’ writes Aye Soe, Director of Global Study and Design for S&P Dow Jones Indices. ‘Yet due to either force of routine or conviction, financiers and advisors think about previous performance and related metrics to be important factors in fund choice.’

Because of the method our brains our wired, we typically think that a shared fund that succeeded in the past should for that reason do well in the future.

But that’s a mistake.

Soe reviewed the performance of 687 actively handled domestic U.S. equity mutual funds.

‘Very few funds can consistently remain at the top,’ writes Soe. ‘Out of the 687 funds that were in the top quartile as of March 2012, only 3.78 % handled to stay there by the end of March 2014. Further, 1.90 % of the large-cap funds, 3.16 % of the mid-cap funds and 4.11 % of the small-cap funds remain in the top quartile.’

In other words, previous performance wasn’t a sign of future outcomes 96.22 % of the time.

Less than a quarter of the leading performing funds were still at the top in the next year.
