How much of this is just because the market as a whole is going up.

This same kind of mentality happened pre-2008. People thought they were great at being day-traders, and had all kinds of algorithms that were 'beating the market'.

But it was just that the entire market was going up. They weren't doing anything special.

Once the market turned downward, that was when it took talent to stay even.

   Show me these things beating a downward market.
