BULL/BEAR MARKET


An Interesting Macro Market Risk Indicator

07/03/14 05:09:05 PM

As a number of macro indicators have hit extremes of late, here is another interesting signal to consider.

Security:   SKEW, VIX
Position:   N/A

I came across an interesting indicator lately which I had not seen before. It is the ratio of the CBOE SKEW index divided by the CBOE VIX index. The SKEW is described on the CBOE website as "an index derived from the price of S&P 500 tail risk calculated from the prices of S&P 500 out-of-the-money options." The higher the value of SKEW rising above 100, the greater the risk options traders see of outlier returns. Increases in SKEW correspond to the increase in perceived risk of rising volatility. In other words, it is the risk options traders see for a 'Black Swan event' in markets.

According to the CBOE website, the VIX index "is a key measure of market expectations of near-term volatility conveyed by S&P 500 stock index option prices. Since its introduction in 1993, VIX has been considered by many to be the world's premier barometer of investor sentiment and market volatility." Many call it the 'fear index' because it rises when investors believe the risk of falling prices is on the rise.

What is interesting is that even though you might assume that both would rise about the same time, the opposite appears to be the case near market tops. Unfortunately, SKEW index data goes back just 20 years making a long-term statistically significant comparison of peaks in the SKEW/VIX indicator with market tops impossible.

But as we see in Figure 1 and Figure 2, it has worked reasonably well since its inception — with one glaring exception. The SKEW/VIX first peaked on December 24, 1993 (Figure 2) about six weeks before the SPX peaked, after which stock prices performed poorly over the next 12 months — not a major Black Swan event but the indicator did accurately warn of a medium-term correction.

At the next market peak in 2000, the indicator was well off its previous peak in 1993 so no warning then which means that any trader watching the indicator would probably have missed the significance of the next SKEW/VIX peak on December 16, 2006.

The chart in Figure 3 shows what happened prior to the beginning of the financial crisis in 2007 with the SKEW/VIX indicator peaking 10 months before the SPX.

In looking back at Figure 1, note that the SKEW/VIX hit a new all-time high in the third week of June 2014 surpassing the previous high on December 16, 2006. Given the past history of the indicator, this signal could not be considered statistically significant. However, when taken together with the recent peaks in other indicators including corporate profits to GDP, Warren's favorite valuation measure of US market cap to GDP and NYSE margin debt which peaked in February (see "Warren's Best Valuation Measure And Other Charts Updated"), the recent peak in the SKEW/VIX ratio becomes even more interesting.
