I see two issues there 1) confirmation bias. Many people have blind faith in the market and while trends are semi-reliable. There are plenty of instances that buck all trends and can take out even the most seasoned day traders accounts if the overrely. 2) a lot of times these are pump and dumb schemes, even by large hedge funds on small companies that are generally overvalued by the time the “opportunity” hits those reading the standard info sources. So as someone simply managing my own account. A solid strategy is to avoid day trade and only place buys on something you are good to be long on and have faith in. These are big ones like Microsoft or apple or Costco. I still invest in companies I’m very knowledgeable on but I don’t take risks on nonsense. And worst case I’m long in some stock for a while But I don’t have to monitor it to the minute nor do I have to really coughing up fees for managed funds at a massive scale. Sure I miss plenty of plays, especially intra-day or intra-week but I also don’t lose anything on those.
