What are some schools or philosophies of investing?

Google gives me this :

https://www.investopedia.com/terms/i/investment-philosophy.asp#:~:text=Popular%20investment%20philosophies%20include%20value,a%20return%20in%20interest%20income.

which isn't really my question.

I'm an adherent of the Bogleheads school of investing, which is essentially “since you can't beat the market, buy the market” I'm familiar with Buffett's emphasis on long-term value, as well as the different systems of market valuation.

I was just wondering if there were any other un/official schools of thought about investing in general, like what kind of philosophy a day trader would follow as opposed to someone heavily into technical analysis. I figure all the major figures (Buffett, Soros etc) would have their own “style” that people try to emulate?
