What Does the Volatility Index Tell Us About Market Sentiment?

In the dynamic world of finance, understanding market sentiment is a critical skill for investors. A valuable tool for gauging this sentiment is the Volatility Index (VIX), created and tracked by the Chicago Board of Options Exchange (CBOE). The VIX, often referred to as the "fear gauge," measures the implied volatility of S&P 500 Index options. In this article, we will delve into how the VIX serves as a contrary market indicator, how it reflects institutional sentiment, and why comprehending the VIX can help investors make informed decisions, particularly when it comes to long and short puts.

Measuring Market Movers

For over a century, investors have sought ways to monitor large market players and institutions. Keeping an eye on these institutional moves is a crucial aspect of successful investing. It's not so much about following institutions to buy or sell shares, but rather, it's about understanding their hedging strategies.

Institutional investors are like massive ocean liners; they can't make sudden moves in the market. If they sense a bearish turn, they opt for put option contracts or sell call options to hedge against potential losses. The VIX becomes instrumental in tracking these institutions because it serves as an indicator of supply and demand for options and offers insights into the put/call ratio.

Option contracts comprise intrinsic and extrinsic value. Intrinsic value represents the portion of the option premium contributed by the stock equity, while extrinsic value factors in elements like time value (the premium paid until expiration) and implied volatility (how the option premium fluctuates based on option supply and demand). The VIX, as mentioned earlier, is rooted in the implied volatility of S&P 500 Index options.

Given the high strike prices and relatively steep premiums of these options, retail investors usually favor alternatives, such as options on the SPDR S&P 500 ETF Trust (SPY), which tracks the S&P 500 Index. When institutions anticipate a bearish market, they are more likely to purchase puts as a form of portfolio insurance.

The VIX surges when there is an increased demand for puts. This upward movement is two-fold; it occurs due to the rising demand for put options and the associated increase in implied volatility. Just as with any product in high demand, the price surges when demand significantly outpaces supply.

Mantra Maxims

One of the age-old adages related to the VIX is "When the VIX is high, it's time to buy. When the VIX is low, look out below!" This saying encapsulates a fundamental principle for investors. The chart below illustrates various support and resistance levels that have been observed in the VIX's history since its inception in 1997.

When the VIX reaches resistance levels, it is deemed high, signaling the right time to purchase stocks, particularly those mirroring the S&P 500. Conversely, support bounces in the VIX indicate market tops and raise red flags for potential S&P 500 downturns.

One crucial aspect to glean from the chart is the VIX's elastic nature. It tends to oscillate within a range of approximately 18-35 most of the time, with occasional outliers as low as 10 and as high as 85. Generally, the VIX reverts to the mean over time. Understanding this characteristic can be a valuable tool, as the VIX's contrary nature aids options investors in making well-informed decisions.

Optimizing Options

Building upon the VIX mantra, understanding its implications for options strategies becomes pivotal. "If the VIX is high, it's time to buy" suggests that the market is excessively bearish, and implied volatility is at its peak. In this scenario, the market is likely to turn bullish, and implied volatility will trend back towards the mean. The ideal options strategy here is to be delta positive and vega negative, meaning short puts are the preferred strategy. Delta positivity implies that as stock prices rise, option prices increase, while negative vega benefits from falling implied volatility.

On the other hand, "When the VIX is low, look out below!" warns of an impending market decline and a subsequent rise in implied volatility. In this situation, the optimal bearish options strategy involves being delta negative and vega positive, with long puts as the preferred choice.

Derivatives During Decoupling

In the world of finance, normal relationships can sometimes shift, and the same holds true for the connection between the VIX and the S&P 500. Instances when these two diverge or "decouple" are relatively rare. Such occurrences, depicted in Figure 2, are often triggered by institutional concerns of an overbought market and contrasting actions by retail investors.

This "irrational exuberance" can lead to institutions hedging prematurely or at inopportune times. While they might be incorrect initially, institutions are quick to correct their course. A decoupling of the VIX and S&P 500 should be considered a warning sign that the market trend may be on the verge of reversal.

In conclusion, the Volatility Index is a powerful tool for investors seeking to gauge market sentiment and make informed investment decisions. By understanding its dynamics and implications, investors can optimize their options strategies and stay ahead of market trends, benefiting from the wisdom of the VIX's historical patterns and its role as a mirror into institutional sentiment.
