How afraid should be you amid the coronavirus outbreak, at least as far as the stock market goes? One of the best ways to gauge how much fear is in the market is the CBOE Volatility Index, better known as the VIX. The VIX, sometimes referred to as the fear index, is derived from the price of S&P 500 index options; it provides a more or less objective measure of real-time sentiment and market stress -- and it as it highest since the 2008-09 financial crisis

Here are some thoughts that might put this into perspective:

No. 1. The VIX might serve as a leading buy indicator: The VIX gives us a sense of exactly how much fear is occurring in the market right now. Some of this is a function of what we don't know; some is simply a recognition that corporate revenues and profits are going to be pressured, perhaps a lot. The big question is for how long.

The current VIX spike suggests this is a much quicker run to 60 than in the past. This implies -- though by no means guarantees -- that when the pandemic runs its course the return will likely be just as quick.

No. 2. It feels as if it is minor until it isn't: During a long bull market, buying the dip becomes muscle memory. Every buy gets rewarded and most sells get punished, at least eventually. Lots of economic and market upheaval can create some concern among investors, though the standard response is that stocks tend to climb a wall of worry. “The trend is your friend,” the technicians says, but the older ones always add “Until the bend at the end.”

No. 3. Things can last longer -- often much longer -- than expected: Bear markets often begin when corporate profits begin to reflect a slowing economy. If you doubt this, just consider the bull market, which lasted 11 -- or seven years, depending on how you measure it -- which is much longer than most analysts and commentators expected.
