“Brent Kochuba Says Stop Selling Options. The Premium Isn’t Worth the Risk Here.” — watch on tastylive.
Brent Kochuba, founder of SpotGamma, joined tastylive for his recurring Gamma Guy show to walk through why short-dated S&P premium has compressed toward its lower bound. Single-stock put selling still cushions the overall index, yet breaking below one level could dramatically shake things up.
Realized volatility in the S&P 500 has drained away through October, running 7.6% over five sessions and 9.7% over the past month while dips get bought and rallies sold near 7,800. Brent Kochuba argues that option premiums have compressed to the point where selling it pays too little for the risk potential ahead.
Short-Dated Premium Has Reached Its Lower Bound
The one-day VIX calculation sits at or near its lowest reading on record, pricing the next session’s S&P options at close to nothing. Roughly 45 minutes after the open, the full-day straddle at 7,800 traded for $15, and implied volatility for the index fell even more than that by mid-morning. Mean reversion behavior around a positive gamma position has crushed realized movement as dealer gamma remains positive, causing them to hedge by buying dips and selling rallies.
Meanwhile, systematic condor and spread sellers continue to feed on little price action in the S&P. After trading costs, the premium collected leaves little room for error.
CPI Is Poorly Priced Into The Volatility Landscape
The S&P term structure carries a small kink at the Wednesday CPI print, worth roughly two volatility points of event premium. One-month at-the-money implied volatility measured 12.4 against a 10th percentile of 12.1, a smidge off the lows. However, the next thirty days hold CPI (October 14), Taiwan Semiconductor’s results (October 15), monthly OPEX (October 16) and the bulk of large-cap tech earnings. With one-month realized volatility near 10, that is thin compensation for the calendar ahead.
Single-Stock Put Selling Still Cushions The Index
Across the top 100 S&P names, dealer gamma reads positive almost everywhere around the current price, heaviest just below spot and largest into December expiration. Persistent put selling is the driver: the biggest day-over-day position change was $14 million of Meta October 740 puts, alongside $5 million of Alphabet December 340 puts and $2.5 million of Microsoft 540 puts. That flow pushes dealers into positive gamma territory: Meta’s peak positive gamma exposure near 735 has acted as a shelf with the stock above 760. Implied volatility in these names has not lifted even as semiconductors sold off, suggesting relatively few traders are paying for near-term downside.
Nvidia Carries The Cheapest One-Month Vol
Nvidia’s one-month IV rank sits at 6, cheaper than most of this year and well under the Nasdaq’s rank of 24. The stock has no earnings inside the next thirty days, so none of the event premium loaded into Alphabet, Amazon or Apple is reflected in the price. Call and put skew are close to balanced after the tech call bid faded with the Nasdaq. Brent walked through owning November and December upside calls on that basis. Capital has rotated into beaten-up corners — equal-weight RSP, financials and utilities bid while semis sold off — which looks more like rotation inside equities than an exit.
7,700 Is The Risk Pivot
Index positive gamma is narrow and clustered at the money, with negative gamma above roughly 7,900 and below roughly 7,600 on the forward TRACE map. A break through 7,825 would be the first evidence that an upside ramp is underway. A trade down through 7,700 — the risk pivot, SpotGamma’s lens on a gamma flip — would strip out that support, and below it hedging turns procyclical as dealers sell futures and equities into weakness. With implied volatility starting from the lows, a quickening move could draw fresh put buying that deepens the negative gamma and feeds on itself. Brent walked through long December SPX puts as the expression if that level gives way.
What Would Change The Read?
We encourage traders to watch two things into the back half of the week: whether CPI gets realized volatility moving, and which of 7,825 and 7,700 the index reaches first. Upside realized movement has outrun downside since the summer, so the topside movement could be the jumpier outcome.
