In the course of conversations with other traders or customers, there will occasionally be subjects that come up repeatedly. In this article, we’re going to look at three of them – sort of an article of short subjects. The first is probably the most complicated, as it addresses what volatility to use when trying to project the profitability of an option position. Second, we’ll share some practical insights on trading in futures options – particularly in the New York markets. Finally, we’ve had a lot of questions about one particular usage of our oscillator, so we’ll address that topic as well.

If it seems that we preoccupied with volatility, it's because we are. It is the only variable factor in determining the fair value of an option; the others are known with certainty at any point in time — strike price, time remaining until expiration, stock price, dividends, and short-term interest rates. However, it has practical and real application as well. If you buy options when volatility is low, then you stand to gain doubly if volatility increases. Or, even if you're wrong on the direction of the underlying market, your loss will be reduced if volatility increases. Some examples may help to clarify these points.

As it stands today, the “Short Volatility Trade” has been watered down to a great extent.  Perhaps in an effort to get ahead of the regulators, most of the Exchange Traded Products (ETPs) that deal with “short volatility” have made adjustments so that their products are no longer as volatile as they had previously been.

As trading opened on Monday, February 5th, 2018, stocks had already been falling for a few days.  Then on that day there was a major decline – the largest drop in point terms in history.  The Dow was down 1,175 points. The S&P 500 Index ($SPX) was down 113 points.  All other major stock indices suffered similar fates.  Those net changes were effective as of the 4 p.m. (Eastern time) close of the NYSE.

Traders are abuzz with the seemingly absurd fact that $VIX is up strongly today (and up for four days in a row), even though the market has risen strongly over that time – and is blasting explosively higher today.  

Forget why this is happening.  Can this be sustained?  The simple is answer is “yes,” of course.  Anything can happen – and probably will – is an old adage on Wall Street (and in life).  But has this ever happened over a lengthy period of time?  It certainly has.

No matter how you measure it, volatility is decreasing. There are several reasons for this – and we’ll discuss them in this article. In addition to traders’ perceptions about forthcoming actual volatility, there are some strategy-related influences, as well as seasonal influences, that are contributing to this most recent decline in volatility.

Let’s begin by noting that the CBOE’s Volatility Index ($VIX) is at or near its yearly lows and hasn’t been significantly lower since September, 2008, prior to the Lehman bankruptcy. The “old” $VIX – trading under the symbol $VXO since 2003 – has already closed at new yearly lows this week. $VIX is just slightly below 21, but $VXO is already approaching 19. While it is true that these volatility measures are based solely on the S&P 500 Index ($SPX) options that trade on the CBOE, they are and always have been a good measure of the overall mood and volatility of stocks in general.

The CBOE’s Volatility Index ($VIX) has been a stalwart for option traders and technicians since it was introduced in the early 1990's. The $VIX measures the implied volatility of $OEX options. However, in recent months, the trading in $OEX options has slowed dramatically, and many traders have forsaken them for the more active and volatile equity options – especially NASDAQ options. As a result, $VIX is becoming harder to interpret. Therefore, we thought that perhaps another Volatility Index could be constructed as a useful supplement to $VIX. It would be a “supplement” rather than a “replacement” because there may come a day when most speculators return to the $OEX market. If that were to happen, then $VIX would regain its former place as a premier measure of public sentiment.
