Your formula is so impressive
Please use your formula to screen the US mutual funds and give us several candidates for purchase. We'll appreciate your efforts.
But past performances are no gurantee of future returns. I picked several top performing mutual funds in the bubble years using the 1yr,3yr,5yr, and 10yr data. Many of them did very poorly in the bear market following the bubble. I had to dump many of them in the past several years in my 401K accounts.
