Short Selling Stock: How It Works And Why We Desperately Need It

 | Dec 19, 2011 07:30AM ET

I often have a hard time trying to explain how short selling stock works and more importantly, why we need it to keep the market alive. Now I understand completely the biggest hurdle that people have to overcome when we talk about short selling stock and it’s the ability to sell something you don’t own yet.

But all too often short sellers get a bad wrap from the main street investing community when in fact short sellers have a vital role to keeping the markets moving and efficient.

What Is It & How Does It Work?

Let me put this into very simple terms. You’ve heard the adage “buy low and sell high” right? Short selling is the exact opposite of that. You first sell the stock at a high price and later buy back the shares at a low price. The part that gets people confused is that the trader doesn’t own the shares they sell.
