Stop calling the VIX the fear index: veteran options trader

Stock averages are roaring toward another hat-trick of records, with the S&P 500 (^GSPC), Nasdaq Composite (^IXIC) and Russell 2000 (^RUT) set to close at new highs. Looking for a window into market sentiment, and where stocks go from here? You might turn to the VIX, the so-called “fear index” — formally known as the CBOE Volatility Index (^VIX).

But a veteran options trader says you won’t find what you’re looking for.

“It is not now, nor has it ever been, the fear index. It was constructed to be the best estimate that we can come up with for 30-day volatility in the S&P 500,” Steve Sosnick, chief strategist at Interactive Brokers, told Yahoo Finance Live.

That’s illustrated by the current level of the VIX — around 20, historically interpreted as showing a higher level of “fear,” and at odds with that rally in the major averages.

So why is the VIX so high when stocks are so high? Sosnick said it’s a question of market mechanics, and focusing on what the VIX actually measures.

Speculative call buying has heated up. That’s when traders buy options essentially betting that indices or individual stocks will rise.

“Call volume is at records and call open interest is at records,” Sosnick said. “There are tons of people who have discovered that calls can be — in a very speculative environment — a way to supercharge the speculation.”

But there’s always another side to the trade.

“Call sellers tend to be professionals, who are quick to raise prices via higher implied volatilities and will hedge their overall exposure with options on related products. That raises the level of implied volatility throughout the system, which is reflected in higher VIX,” Sosnick wrote in a recent blog post outlining the phenomenon.

All of that said, the VIX can at times act as a sentiment indicator. But that’s “more a matter of convenience and correlation than construction,” Sosnick wrote.

So if not the VIX, then what? That’s where it gets tricky, Sosnick said in a follow-up email.

“The problem with sentiment indicators is that there is no single foolproof measure,” he said. He mentioned the put-call ratio as a contrarian indicator, “but even that has severe limitations.”
