How do NQ and QQQ track so closely?

Has any personal trader not with a firm been successful with arbitrage like this? It seems it is to quick for a lone trader to capture anything.
Actually, I know a guy who trades smaller ETFs (less liquid) as well ETFs that involve non-traditional assets or have incomplete holdings. It's a bit more statistical and requires a lot of work, but there is definitely money there.

about 10 years ago I was part of a two person team that surprisingly made some money doing this with a liquid ETF (penny wide quote) and illiquid constituents (sometimes 50 cents wide). I was a bit amazed it worked.

I’ve seen it work even recently, but it’s so capacity constrained that you might as well get a job.

Don't you have to be an authorized participant to create/redeem? Or is this guy warehousing the arb and then waiting for prices to swing in other direction (from NAV discount to premium or vice versa) to unwind?

The latter - essentially waiting for the authorized participants to push the price in their direction.
