Cboe's head of market intelligence said it's seeing near record bets on the VIX fear gauge spiking as traders seek crash protection.

Changes of sentiment don’t cause markets to ebb and flow; but their short-term fluctuations, which are largely random, affect sentiment.

Equity market volatility has been crushed. Does this lack of fear suggest complacency, or historically has this been a good time to invest?

It's not called the "fear gauge" for nothing - and some strategists are keeping their eyes extra peeled.
