Can Mutual Fund Efficiency be the idea of choosing your Winners and dropping Laggards?
I compiled a chart right here with heatmap. Let’s see if this assertion holds.
Chart of Mutual Fund Efficiency – Final 12 months return each half 12 months foundation

What seems to me is that on this comparative heatmap foundation, if an asset class turns into inexperienced, it’s time to transfer to the opposite facet.
Or, ought to it’s wager on the belongings which have turned pink or a shade of it?
Or, ought to we simply diversify as we don’t know what’s going to work when?

Now, how would your funding portfolio change on the idea of this data?
Do you assume utilizing “reversion to the imply” foundation may very well be used for selecting the asset class / fund? (Winners change into laggards and vice versa)
Wanting ahead to your feedback.
