In an article for MarketWatch, Mark Hulbert discusses the collapse of the volatility index (VIX) over the last couple of months, and why it could be a harbinger of a sustained stock market rally according to historical data. 

According to Hulbert when the VIX reaches a fresh, 3-year low, it’s likely to remain low for a couple more months which implies further gains for equities. However, this view is contrary to the consensus expectations on Wall Street which see further erosion in the economic outlook, causing the economy to stumble into a recession. This perspective sees the low Vix as a sign of complacency rather than a ‘continuation’ signal.

Hulbert points to history. Since 1990, the best performing months from a risk and return perspective, have come with low VIX readings. Based on this data, investors should increase equity allocations as the volatility index declines and reduce it as it rises.

Another benefit of this strategy is that it dampens the impact of volatility on the portfolio which increases the odds that investors will stick to their investment plan and not let the market’s twists and turns shake them out of their holdings. 

Finsum: Many on Wall Street see the plunge in the volatility index as a contrarian signal, implying complacency. Mark Hulbert disagrees and sees it as the start of a sustained rally.
