So... what' you're saying is that I and others of my ilk (1) "made our money doing something which was later declared illegal", (2) "our gains had nothing to do with TA." (I don't know about the other guys, but I've been a TA'er since way back when... just like I am today.)
WRONG ON BOTH COUNTS!
Sorry Surf, you apparently don't understand "mutual fund timing" either. Fund timing was never made illegal. And it wasn't significantly different than trading ETFs today, other than funds having the negative of "end of day" fills. (If ETFs had come along before mutual funds, there likely would never have been a mutual fund industry at all.)
Mutual fund timing was mostly about "relative strength rotation" and buying the dips, much like everything else today.
What WAS made illegal was some funds "past posting" price executions for certain traders. That wasn't "mutual fund timing", either.... that was just plain cheating.... I wasn't involved in that.
With your "understanding" then, those who "made a fortune" timing mutual funds should be doing even MUCH better today with ETFs. (I suspect you're exaggerating about "knowing guys who made a fortune with fund timing"... perhaps some of the cheaters?)
Then as now, making money had EVERYTHING to do with "proper TA" for guys like me.
