Nothing more than irrational reaction by retail traders. Do you really think it is going to save your ass if the hedge funds, banks and brokers (sharks) want to tank the market? All they need to do is drive the bid price so low, you will be crying uncle. How are you going to get out of your losing positions if there are no buyers? Retail traders (sardines) have no say in how the stockmarket moves. Even if you take all the monies of all retail traders (sardines), you are not going to move any stock for that matter. Okay, maybe, you can move some penny stocks but, retail traders (sardines) will be trading against other retail traders (sardines). Best stay in the kiddie pool and day trade with other retail traders (sardines). If you want to play with the hedge funds, banks, brokers (sharks), stay out of their way, feed when they feed. That way, you get the bits of food they chewed on. Scraps maybe, but, that is enough to feed you. Stay in front of them and they will swallow you whole and chew you in tiny, little pieces. Your choice.
