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...
