They are far better than we blindly do research. The main issue is asset allocation for us.
They buy every day small amount. During my time, they bought TSLA many days , but they also sold TSLA many times which will confuse us. In some cases they will sell to release some money to buy another one. We may not know why they buy and why they sell suddenly?
The best way is to subscribe to them, do a research on those stocks and buy/sell depending on own decision.
