"Disregarding the big swing and trying to jump in and out was fatal to me. Nobody can catch all the fluctuations. In a bull market your game is to buy and hold until you believe that the bull market is near its end. To do this you must study general conditions and not tips or special factors affecting individual stocks. Then get out of all your stocks; get out for keeps! Wait until you see -- or if you prefer, until you think you see the turn of the market; the beginning of a reversal of general conditions. You have to use your brains and your vision to do this; otherwise my advice would be as idiotic as to tell our to buy cheap and sell dear. One of the most helpful things that anybody can learn is to give up trying to catch the last eighth or the first. These two are the most expensive eighths in the world. They have cost stock traders, in the aggregate, enough millions of dollars to build a concrete highway across the continent."
