On structure. The source run records more than one leg on this name that day. Any single-leg return quoted below is that leg's move, not the net result of the whole position — offsetting legs change the outcome.
Almost every flow write-up you will ever read is about somebody buying calls. That is a selection effect, not a fact about the tape — bought calls make loud, fast, screenshot-friendly charts. This trade made nobody a screenshot, and it worked anyway.
On April 29, 2026, with Marvell (MRVL) at $156.57, our Unusual Options Activity scanner flagged a sale of January-2027 135-strike puts at $22.95 — about $6.3 million collected, roughly 2,745 contracts on a premium-derived basis.
Selling a put is a bullish position. The seller gets paid now and takes on the obligation to buy MRVL at $135 if it falls there by January 2027. They keep the whole $6.3M if it doesn't.

One structural detail worth pausing on: at a $156.57 spot, the 135 strike was 14% below the money. The seller wasn't reaching for premium at a strike likely to be tested — they were getting paid $22.95 for a cushion of 14% and eight months of time. That is a position sized to be boring.
What happened next
MRVL went the seller's way, hard.
| Date | MRVL close | 135P close | Position |
|---|---|---|---|
| 2026-04-29 (print) | $156.57 | $22.95 | collected $6.3M |
| peak | $316.43 | — | put deeply out of the money |
| 2026-08-27 | $241.45 | $3.72 | ~84% of premium captured |
The stock roughly doubled at its high and sits 54% above the entry today. The put that was sold for $22.95 is worth $3.72. The seller has captured about $19.23 per contract — roughly 84% of the maximum possible profit — with nearly five months still to run.
Note what did not happen: no 700% chart, no headline multiple. A put sale's best case is that it quietly goes to zero, and this one is most of the way there.
Why this trade is worth more attention than a call buy
The payoff is asymmetric in the boring direction. The seller's maximum gain was $6.3M, fixed on day one. Their downside, if MRVL had collapsed to $100, would have run into the tens of millions. Anyone taking that shape is expressing a high-probability, capped-reward view — which tells you something quite different from a lottery-ticket call buy, and is often the more informed position.
It only reads as bullish if you know which side printed. This is the single most common misreading of options flow: a put is not bearish. A bought put is bearish; a sold put is bullish. Volume alone cannot tell you which. When we publish a daily put/call skew, this is exactly why we never state the ratio without saying so.
Time was the asset, not the direction. The seller needed MRVL to not fall 14% in eight months. That is a far easier bar than the one a call buyer sets, and it is why premium-selling structures show up so often in genuinely institutional flow.
Being straight about the denominator
Across the eligible prints we score — opening trades with a claimable direction, aged past our 60-day publishing embargo — roughly half work. MRVL is in the good half. It is also, unlike most of what gets written up, still open: the January 2027 expiry is months away, and a sharp reversal could still take back part of that 84%.
We publish these once a position has resolved enough to judge, not once it looks good.
