Of all the misreads in retail flow analysis, the worst is interpreting every put buy as bearish. A large fraction of put volume is hedging - funds protecting long stock positions, not betting on a decline. The trade structure tells you which is which.
Hedging signature
Long-dated, ATM or slightly OTM puts. Often combined with stock prints in the same name on dark pools. Bought at midprice or slightly below - patient execution. Conservative strikes (90-95% of spot). The trader is paying for insurance, not betting on a crash.
Speculation signature
Short-dated, OTM puts. Often a sweep on the ask. Far strikes (70-85% of spot) implying a real move down. No corresponding stock activity. The trader is making a directional bet that the stock falls hard, fast.
Putting it together
- Days to expiry < 30 + OTM strike + sweep + no underlying flow → speculation. Bearish read.
- Days to expiry > 60 + ATM strike + block + paired stock buying → hedge. No directional read.
- Mixed signals → unclear. Default to no signal rather than over-interpret.
The volatility tell
Hedging activity often coincides with depressed put skew - funds are buying when insurance is cheap. Speculation pushes skew higher quickly. If you see unusual put activity while skew is collapsing, that is hedging. If skew is expanding, that is fear or conviction.
Why this matters
Trading on the wrong read here costs money. Shorting a stock because of 'unusual put buying' that is actually a hedge against a long position is fighting flow that is not directional at all. Always classify before you interpret.
