> So - if that is true, why not buy the heavily weighted stocks directly and do your own financial analysis on them? For instance, I look at past 5 year sales growth. Then I look at yoy sales growth. Then I look at P/S over the last 5 years (to see if it is out of whack). Then I look at PEG over the last 5 years (to see if it is out of whack). Then I look at gross margins. Then I look at dividend yield. All of this data is available for free.

I'm not really sure how to do all those things, and I'd rather spend that learning how to make database things work.

Also, it sounds like all you're doing is looking at (very recent)past performance (not a predictor of future performance), and putting all your eggs in one basket (big tech).
