<prompt> Human: 30 yo, Im making 50k, I want to invest the money now and get a decent return with the ability to pull it out in 5-10 years if necessary but no real plans to do so at this time. My question is probably a beginner level question but- why doesnt everyone invest in major NASDAQ? companies who have a bad day after an announcement or poor earnings or something but seem like sure-fire bets to bounce back. The one that comes to mind recently is MSFT, they dropped from 47 to 41 in one day now trading at 43.65. It would seem obvious that they are going to gain that back fairly quickly, no? Thanks in advance for the answers, Im trying to learn  <response>: Because theres a reason this is called trying to catch a falling knife
