Selling puts in a bear market
What happens to put selling when the market trends down, what our replays found below the 200-day moving average, and why a stand-down is insurance rather than an edge.
Why bear markets are different for put sellers
A short put is a bet that the underlying will not fall far before expiry. In a bull market the drift helps. In a bear market the drift works against every position, implied volatility rises but realized volatility often rises with it, and losses arrive as gaps that no daily check can exit in time.
Rich premiums in a selloff look like an opportunity. In our cash-secured put data, trades entered when implied volatility was richest relative to recent realized volatility had the lowest win rate, about 79% against 86% for the cheapest quartile. High premium was a warning, not a gift.
What the history says
Every short premium cell we tested at every holding window was negative below the 200-day moving average. That held for put credit spreads, cash-secured puts, SPX same-day spreads and short-dated weekly cells, four independent confirmations. A 25-delta QQQ put on the same days was positive above the line and slightly negative below it.
Over a decade the put credit spread on QQQ was still positive in nine of eleven years. The two losing years were 2018 and 2022, about -3.4% and -5.4% on the dollars at risk per trade. A bear year cost the program a fraction of a good year's gain, provided the size was small enough to survive it.
Does timing help?
A stand-down rule, such as no new short puts below the 200-day average, sounds like the obvious fix. Out of sample it did not beat always holding the spread over 2018 to 2026, and it helped in 2022 only in one variant. Every regime classifier we tried, on trend, VIX level, term structure or a volatility premium proxy, failed to beat always on in walk-forward tests.
The honest reading is that a stand-down is insurance with a known cost. It gives up some good trades in exchange for avoiding a regime where the evidence is consistently negative. That can be worth it, but it should be chosen for that reason, not because it was shown to add return.
What does pay below the trend line
The structures that paid in a falling market were directional. A bear put debit spread was clearly positive below the 200-day average on QQQ and negative above it, but the evidence rests mostly on one bear year. A long straddle paid when the VIX curve was inverted, on a small sample. Neither is premium selling.
For a put seller, the defenses that measured are size and diversification. The guide on position sizing covers what share of equity at risk kept a 20% drawdown unlikely, and the guide on selling options on leveraged ETFs covers why the worst trades in a selloff come from the most volatile wrappers.
Historical replays are not a forecast. Options can lose more than the premium collected. This is education, not a recommendation to trade anything.
