Trading is a great place for physics PhDs because there is way more upside and the rigor gained during your studies adapts well to studying the markets.

Also depending on what level of magnification you use to observe the markets: they are just random. Maybe there is some consistent process that works today on some subset of the market given a certain forward-looking horizon.

Then, that opportunity disappears at some other time in the future. Its ephemeral and fleeting... and this is probably where the daily challenge comes in.
