This Is Your Brain...On a Bull Market

On some days, when he is depressed, Mr. Market will offer you stocks (fractional ownership units of businesses) at prices that are well below their underlying businessesâ?? economic value. On those days, you should buy from Mr. Market. On other days, when he is manic or euphoric, Mr. Market will bid for stocks at prices that are well above their underlying businessâ??s economic value. On those days, you should sell to him.
