In general, the investment/trading community equate volatility to risk, at least to first order.
Two questions for you:
1. Do you agree?
2. Over most 3 decades windows, QQQ > SPY. Does it mean the more volatile QQQ is not really higher risk?
Or like some writing naked options.Yes, insurance companies do it

But if you have the time, over a long time QQQ always (almost) beats SPY meaning higher volatility doesn't mean higher risk, using Graham's definition of risk.Different economic sectors offer various rate of returns during different times, last three decades progress and technological advancement concentrated in IT and since QQQ provides higher exposure to those stocks returns are higher. But as Businessman rightly mentioned it was reflected in higher drawdowns, so I don't see any controversy with risk's definition as variability of future outcomes, expressed in current volatility.

Up almost $22k since April 30th. Now where do I get my hands on a million bucks!? lol
