Traders and investors everywhere are spooked by volatility whenever it rears its head. We hear about it every time stocks take a tumble, even if that doesn't happen so much these days. So the Investopedia definition I'll show you is probably the last thing they're thinking of.
"Volatility: A statistical measure of the dispersion of returns for a given security or market index. Commonly, [emphasis mine] the higher the volatility, the riskier the security."
Now, that doesn't sound so scary, does it?
Volatility is nothing more than a statistical tool that shows how much a stock goes up or down. Yet many see volatility as a bad thing, because they equate it to risk. And risk is bad for us, right?
Well, sometimes risk is bad. But to the smart investor, volatility is a difference maker. Because without it, you might as well just buy a CD. More importantly, you have zero chance of beating the market. And where's the fun in that?
That's right: Without volatility, you don't beat the market.
That's why one of my 10 Trading Commandments is "Volatility is a trader's best friend!"
