CBOE Equity Put/Call Ratio Drops to 0.38, Downside Protection Demand Falls to Multi-Year Lows
nashnova research
The CBOE equity put/call ratio fell to 0.38 on September 29, its lowest since 2023 — a sign that options-market demand for downside hedging has retreated to an unusually low level, historically a marker of peak optimism.
What does a reading of 0.38 actually tell us?
The CBOE equity put/call ratio — total equity put volume divided by call volume — printed 0.38 on September 29.
This means → for every 1 call traded, only about 0.38 puts changed hands. Far fewer investors are buying insurance than betting on further gains.
It is the lowest reading since 2023, showing that concern over a possible sell-off has dropped to a multi-year low.
Why have investors stopped buying protection?
Put volume — contracts that profit when stocks fall — has shrunk sharply relative to call volume, which profits when stocks rise.
In plain terms = investors collectively decided they don't need an airbag, because they're convinced the car won't crash.
This reflects a market in a deeply optimistic phase, where most participants see tail risk — the chance of an extreme drop — as not worth hedging.
What does this extreme optimism signal?
Historically, this structure appears when bullish sentiment is near its peak — not a guarantee of an imminent decline, but a sign that almost nobody is positioned for one.
This means → if an unexpected shock hits, unhedged positions may be forced to liquidate simultaneously, amplifying short-term volatility.
In plain terms = when nobody carries an umbrella, a sudden downpour sends everyone scrambling for cover at once — and the price of umbrellas spikes instantly.
