And how's that different than pork chops again?
Pork chops can go on sale as a loss leader to generate other sales or if they are about to go bad and need to be consumed soon. Stocks never go on sale. They are always priced where most people think they are worth at that point in time. People shouldn't buy a stock just because the price is 30% off from last week. What the price used to be has absolutely nothing to do with what it's worth now. Wise shopping at the grocery market is not the same thought process as wise shopping in the stock market. I cringe when people say stocks are on sale, as if they are bargains, a special deal. They are not.
