Although we don't believe in timing the market or panicking over daily movements, we do like to keep an eye on market changes -- just in case they're material to our investing thesis.

Even with today's rise of 86 points for the Dow Jones Industrials (^DJI -0.65%) as of 12:30 p.m. EST, the well-known market benchmark is still down in early 2014. Yet even as calls for a possible correction get louder, one important gauge of fear in the market remains at historically low levels, suggesting continued complacency among most investors.

The S&P Volatility Index (^VIX 11.09%) ordinarily perks up when the market shows signs of falling. But so far in 2014, the so-called Fear Index has fallen another 12% as of midday today, remaining at levels that rival its lowest readings in seven years. That has led to further losses in the iPath S&P 500 VIX ST Futures ETN (VXX), which is down 4% to date this year, while the inverse ETN has risen by a similar amount.

Anecdotally, it seems volatility has picked up in certain pockets of the market. Perhaps the most obvious lately has been the biotechnology and pharmaceutical area, where huge moves for development-stage companies have become the norm. Intercept Pharmaceuticals (ICPT) became the poster child for volatility in the past week, with the stock soaring from $72 to $446 per share last Thursday and Friday before giving back $200 per share in the past couple of days.

Earnings-related announcements have also led to substantial volatility, especially to the downside. Just yesterday, both lululemon athletica (LULU -0.41%) and SodaStream suffered respective drops of 15% to 25% after giving disappointing early reads on their holiday seasons. Such preannouncements aren't all that unusual, especially with high-growth stocks whose share prices build in high expectations of future results. Yet the magnitude of downward share-price movements in response to these news events seems to be heightened, perhaps because of the outsized gains the market posted in 2013 and previous years.

Still, for now, investors appear unconvinced that the modest pullback that stocks have seen so far this year will amount to anything more than the minor dips that have occasionally punctuated the bull-market run of the past five years. Unfortunately, it seems increasingly unlikely that the Fear Index will give an early warning sign when a more severe correction comes.
