Cheap NDX Straddles and What They Signal
Short-term straddles on the NASDAQ 100 (NDX) sit near historical lows, with the VIX under 15 and the S&P 500 close to record highs. A straddle is an options bet that profits when the market moves far in either direction; a cheap one means traders expect little movement.
Coming into today, the at-the-money NDX straddle priced a 70 basis point range. The market moved about 1.3%, so a close near this level would fall outside that range. That makes today likely the first day since last Wednesday that the straddle was mispriced. For the days before, straddles were accurate and built in enough cushion. This feeds into measures like the VIX and the VXN (the NASDAQ 100's volatility index).
Is the options market pricing total calm, or are traders getting complacently cheap on downside protection? The data leans toward accurate pricing until today, not blind complacency. One extra point: VXN seasonality over the past decade puts the calendar-year low on August 14th - a time of low realized and implied volatility. Whether that means a near-term move up is unclear.
The information built into option values, especially index options, is highly valuable whether or not you trade options. The speed at which the market repriced risk through 2026 supports paying attention to optionality.
Options Activity Versus the Bullish Narrative
Little in current options activity counteracts the view that investors are increasingly bullish. Markets capitulated in late July, then trended higher. Since then, put skew in index options has come in sharply - fewer traders paying up for downside puts, which fits a bullish stance. Financial conditions sit at arguably multi-decade lows, which supports a risk-on market.
Pockets of concern: interest rates keep pressing periodically. The Jackson Hole Symposium at the end of the month is a risk, because this Fed seems set on giving less forward guidance. That uncertainty can build if upcoming data comes in worse than the recent benign inflation figures.
Index Volatility Versus Single-Stock Volatility (Dispersion)
Options on Apple (AAPL), Amazon (AMZN), Alphabet (GOOGL), and Cisco (CSCO) all flow into the top 25 names of the NASDAQ 100. The average of that single-stock volatility, tracked over time, expands and contracts against index-level volatility. When the market does well, the gap usually expands - seen strongly over the past 6 to 8 weeks.
Both measures have come in recently, but single-stock volatility is falling faster on a relative basis. That makes sense moving through earnings season. The bigger risk to the market is a highly correlated event, where all names move together. In those cases index volatility outperforms single-stock volatility, which is why index hedges can be so powerful for someone using options at home.
The SPY-NDX Options Relationship
The real signal to watch is the relationship between S&P 500 (SPY) and NASDAQ 100 (NDX) options, rather than just SPX or the VIX. One-month, 10% out-of-the-money NDX options, measured in volatility terms against the S&P 500, reached their widest premium since the early 2000s about a month ago.
That matters when choosing where to hedge or sell premium - which index expresses the trade most effectively. The bottom of the picture: NASDAQ 100 price performance divided by S&P 500. When that line trends higher, the NASDAQ 100 is outperforming; when it falls, it is underperforming. There is high correlation between NDX option premiums holding value and the NASDAQ 100 outperforming.
So for hedges now, NDX may hold value in volatility terms better than an S&P 500 hedge. The reason: the semiconductor and technology names leading the market are more concentrated in the NASDAQ 100.
Semiconductor Options as a Leading Indicator
Semiconductor options can act as a leading indicator for the broader market, not just a reflection of it. Since the end of 2022, the market story has centered on semiconductors and whether they behave like or unlike software.
The same measure - the 10% out-of-the-money one-month put - applied to the semiconductor index (SOX, tradeable via SMH) against the NASDAQ 100 shows correlation above 80% over a multi-year window. Lately semiconductor volatility has come in faster and turned earlier than volatility at the index level. Watching how semiconductor volatility behaves is a way to read risk appetite and where the market may head over the coming days or weeks.
