if everything always happens the same way in the future as it did in the past we would all be rich because you would not have to guess you would know. The fact is just because a stock goes up, or down in the past has little to know influence on what it will do in the future. Otherwise you could endlessly drop down to the bid everytime and never buy more shares eventually you would be wrong and it would not go that low. I hope that time has already come.
