A good rule is to never average down (buying more of the stock as the price falls), only add to holdings if price rises. If price is going up your analysis appears to be correct, if its falling you've got something wrong. Basically the big players ie those with inside info or savvy enough to build up big pools of funds move prices not the small punters. If the price is falling the big players generally are selling and if its rising the big players are buying. Many people average down into falling stocks that eventually go into receivership or close to it. This one rule is very important and will keep you out of big capital erasing situations, stick to it.
