As oil prices have fallen, many investors with exposure to energy companies have wisely kept an eye on VIX. But there is another volatility benchmark – one more suited to energy equity investments – which investors should also watch carefully: VXXLE.
VXXLE is the ticker for the CBOE Energy Sector ETF Volatility Index. This index has same methodology as VIX. However, instead of tracking S&P 500 options, it is based on options tied to the Energy Select Sector SPDR® Fund, a popular ETF known by its ticker, XLE.
VXXLE measures the 30-day implied volatility of XLE and by extension, the index it follows, the S&P Energy Select Sector Index. Just as VIX is inversely correlated to the S&P 500, VXXLE is inversely correlated to XLE, as the chart below shows (3-year correlation = -0.66).
Even though CBOE does not yet offer derivatives based on VXXLE, this index still has great value as a benchmark, particularly when coupled with other related information. As an example, some analysts compare the changing value of a volatility index with the price-to-earnings ratio of the companies in the underlying index.
Analysts say that when such a ratio is high, the market may be complacent and a prudent investor might want to scale back their exposure. On the other hand, if this ratio moves to a lower range – indicating prices are relatively low and anxiety is high – a “crash” may be under way and there could be an opportunity to take a contrarian position.
In the case of VXXLE, this ratio has moved drastically over the past year. As the chart above shows, this ratio has gone from its 3-year high to a record low. And in line with this, the S&P Energy Select Sector Index has tumbled, at one point losing approximately 25% of its value.
If you want to use VXXLE to inform your investment decisions, you can access more information on Chicago Board Options Exchange’s website. Also, a tutorial on VIX’s methodology, which VXXLE shares, can be found here.
*Author’s note: Due to data limitations, the second chart uses the P/E for the S&P 500 Energy Sector Index instead of the S&P Energy Select Sector Index. These indices share the same constituents but use different weighting schemes.
