There is no need to buy high valuation tech companies

Unless you are managing upwards of a hundred million dollars there is no need to pick the best priced megacap company. Reason being there is still a decent number of stocks one can buy without creating price action. I invest almost exclusively in penny stocks, and have been making about 40% a year compounding for 8 years so far. My point is, a lot of you are following the crowds to the megacaps, providing liquidity to large fund managers. That's all well for the broader market, but why focus solely on megacap American stocks?
