Even though Ryan did an impeccable job at explaining shorting stocks, I just thought of an even simpler explanation using candy bars instead of stocks. @MattJonesRadio @DrewFranklinKSR @ShannonTheDude @ryanlemond
If you buy a candy bar for $1 and sell it for $1.50 you make $.50 profit. Everyone understands that. You expect that the price of candy bars will go up. But what if you expect the price of candy bars to go down? That is where shorting stocks comes into play.
Shorting a stock is like bumming a candy bar worth $1 from a friend with the promise that you will replace it in a week. You then decide not to eat it, but to sell it to someone else for $1. So you have $1 in your pocket, but you owe a candy bar worth $1 so there is no gain.
But, if the price of candy bars drops to $.50 during the week, you have $1 in your pocket from the original sale but the replacement candy bar only costs you $.50, so you make $.50 profit overall.
Buying stock has unlimited profit potential, but low risk. You can only lose your original cost. Say you buy a $1 candy bar to sell, but your stupid brother eats the candy bar before you could sell it. The most you could lose is the original price of the candy bar or $1.
