This one is a winner with a lesson buried in it, which makes it more useful than a clean win.
On January 15, 2026, with Moderna (MRNA) trading at $39.36, our Unusual Options Activity scanner flagged a $12 million purchase of June-18 40-strike calls at $6.75 a contract. Premium-derived, that's about 17,778 contracts — a large, barely-out-of-the-money position with five months to run.
The thesis was not subtle: somebody thought MRNA was going up, and soon-ish.
They were right. The stock closed at roughly $64 on June 18, and the calls settled at $23.95 — a 255% return, turning $12M into about $42.6M.

A note on that contract count, because it matters more than people expect. The tape reported a larger volume figure than 17,778. We derive contracts from premium ÷ price, not from reported volume, because UOA volume is routinely inflated 1.5–10× by cross-prints and multi-fills. $12M at $6.75 is 17,778 contracts, whatever the volume column says. Every number below follows from that.

The position worked. It worked well. $12M became roughly $42.6M in five months, on a stock that gained about 62% over the same stretch — the leverage did exactly what leverage is supposed to do.
The part that should bother you
MRNA did not stop at $64. It kept climbing, reaching $174.38 before settling back to $142.77 by late August.
Had that same $12M been spent on a January-2027 40-strike call instead of the June contract, the position would have been worth a multiple of the $42.6M it actually returned — the stock more than tripled from the entry, and the calls were 40-strike against a $174 high.
The thesis was right. The expiry was wrong. And this is the failure mode that almost never shows up in flow write-ups, because it doesn't look like a failure — it looks like a 255% win, and nobody scrolls past a 255% win to ask what it cost.
Compare it with the SNDK trade we published: $17M into a January-2027 strike, ten months out. That buyer paid more for time and captured the full move. Same conviction, different structural choice, materially different outcome.
What this trade is actually evidence of
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. MRNA is in the good half, and comfortably so, but it is not evidence that following flow is a strategy. It is evidence that a $12M same-day print on a barely-OTM line is worth knowing about.
What you do next — which strike, which expiry, whether to take the trade at all — is where most of the outcome actually lives. This trade is the proof: the buyer got the hard part right and still left the majority of the move on the table.
