His style are just picking the ones that are cheaper at the time and hope the company makes it. That is basically holding for years.

You probably won't believe me but traditional investing works a bit more complicated way rather than just buying some shit and praying for it to rise in price. There are a lot of multiplicators and other indicators with different difficulty that would help you to see if a company is undervalued or not.
