The ultimate successful strategy
The best stock strategy is summed up in four words. BUY LOW, SELL HIGH. You want to buy a stock at a lower price and sell it at a higher price. What is the low price and what is the high price is the hard part - and that's your challenge!
This does not mean you need to find the very bottom of the stock's price. Catching a stock on the rise is still profitable.
This does not mean you should automatically sell a stock the first time it declines. A decline in stock may just be a temporary adjustment, and it may rebound immediately. Of course it is also possible that this is the first step in a steady decline...
