At 3:47 PM Berlin time, something unusual happened: While Amazon shares climbed +1.6% to $270.13 and markets felt complacent, put volume at the $260 strike (expiry May 20, 2026) exploded. This is not random.
What Happened
Amazon (AMZN) closed May 13 at $270.13, up $4.31 or 1.62% — superficially bullish. But the options chain tells a different story: Unusually high put activity at the $260 strike, over 20,000 contracts above average volume. Volume-to-Open-Interest (V/OI) ratio above 1.5 — a clear signal of fresh institutional money.
The question is not if smart money is hedging — it's why. Amazon rallied +8.5% over the last month, driven by strong AWS numbers and positive earnings guidance. Why buy puts now?
The Options Side
The $260 strike is mathematically interesting: 3.7% below current price, but exactly where Amazon traded in early April. Institutions are betting on mean reversion — the probability that Amazon returns to baseline after this rally.
Implied Volatility (IV) for these puts rose to 28.4%, compared to 24.1% for at-the-money calls. Translation: The market is pricing higher downside probability than the stock price rally suggests. Weekly puts with only 6 days to expiry are more expensive than they statistically should be — a classic warning sign.
For context: On May 7, when Amazon traded at $249, put activity was 40% lower. Today's volume is not routine — it's positioning.
What Traders Are Watching
Three concrete levels will decide the next few days:
- $270 Resistance: If Amazon closes two days below $270, short sellers get aggressive.
- $260 Strike Cluster: Highest put open interest sits here. If the stock drops below, it triggers gamma hedging — market makers must sell shares, accelerating the fall.
- $255 Technical Support: The 50-day moving average. A break below triggers technical sell signals.
Earnings are not until June 27 — this put activity is not earnings hedging. It's either a bet on macroeconomic shocks (rates, inflation) or on internal Amazon data only insiders know.
If you're long, ask yourself: Why are professional traders buying insurance against a 3.7% drop when sentiment is bullish? The answer rarely lives in the charts — it lives in what's not yet public.
