1)      Move to sunnier climates: permanently avoid more risky stocks

The “low volatility effect,” sometimes called the low volatility “anomaly,” refers to the tendency – manifest across a wide range of markets – for stocks with low volatility to outperform their peers, especially in terms of risk-adjusted returns. While academics continue debate the underlying dynamics – a behavioural explanation supposes that speculatively minded investors will gladly overpay for a potentially oversized return** – investors can capture this effect through indices that underweight or remove stocks with higher volatility. The S&P 500 Low Volatility Index removes 80% of the most volatile stocks from the index and weights to the remainder inversely proportional to their historical volatility.

2)      Go back inside when it’s wet: exploit regimes in volatility

Volatility tends to persist: the level of the volatility today can be a guide to volatility tomorrow. If markets are currently choppy, it therefore may make sense to de-risk going forward. Systematic “risk control” indices realize this approach by explicitly targeting a prespecified risk level, dynamically allocating between equity and cash (in more volatile periods) in order to maintain the target. As well as potentially providing better performance, indices with such controls have gained widespread traction because of the reduced costs of protection – significantly cheaper put options in particular.

3)      If everyone else is preparing for a storm, maybe you should too

The so-called “fear index”, VIX, reflects market expectations of future volatility. Surprisingly (perhaps), a high level of actual volatility shows a mild historical bias towards a subsequent positive return for VIX futures. Additionally, the VIX has also historically shown trending behaviour (if people are getting more worried, maybe you should too). Taken together, this suggests that a high and increasing VIX is a potentially useful signal.

Strategies that aim to capture trends or regimes typically show performance somewhat idiosyncratic to the specifics of their individual signal construction, but with nearly four years of live history the S&P VEQTOR Index provides a concrete example of the latter concept, using levels and trends in volatility to allocate between the 500® and short-term VIX futures.
