Super Micro Computer's (SMCI) 33% single-day collapse left a trail of destruction across its options chain — but the data tells a more nuanced story than it might first appear.
Super Micro Computer shares closed at $20.53 on Friday, down 33% on the session, after overnight news that individuals linked to the company, including a co-founder, were charged with assisting in the smuggling of at least $2.5B worth of AI technology to China. The options chain for the March 27 expiration lays bare the carnage — but reading it carefully reveals two very distinct groups of traders: those who were positioned before the news broke, and those who scrambled to react once it had.
The bulls who never saw it coming
The most telling evidence of pre-existing bullish positioning sits in the call side's open interest figures. The $31 call carried 21,470 contracts in open interest heading into Friday, while the $33 call had 23,853 — both strikes now sitting so far above the stock price as to be essentially worthless. These were not positions built on Friday. They represent accumulated bullish conviction established over previous sessions, by traders who had no reason to expect what was coming. Friday's session wiped them out almost entirely — the $22 call lost 89% of its value, the $23 call 92%, the $24 call 94%.
The puts that look prescient but probably aren't
At first glance, the put side appears to tell a more concerning story. The $20 put saw 63,531 contracts traded on Friday, with percentage gains running into four figures across multiple strikes — the $22.50 put gained 5,140%, the $23 put 5,900%. Numbers like that can raise uncomfortable questions about who knew what and when.
But a closer look at the data offers a more straightforward explanation. The $20 put shows 63,531 contracts traded against open interest of only 12,340 — a ratio suggesting the overwhelming majority of that volume was opened on Friday itself, after the charges were already public knowledge. This was not prescient positioning. It was a rush to the exits — and to the downside — by traders reacting to news that was already in the market when US exchanges opened.
The extraordinary percentage gains on the puts are similarly explained. When a stock falls 33% in a single session on a breaking news event, even modestly priced puts can deliver spectacular returns on an intraday basis. The gains reflect the severity of the move, not foreknowledge of it.
The shape of the damage
What the options chain ultimately shows is a stock that was ambushed. The pre-existing positioning was heavily bullish — accumulated call open interest at strikes well above the stock's closing price tells the story of a market that had no meaningful downside hedging in place before the news broke. The put activity that followed was reactive, not predictive.
For the traders holding those $31 and $33 calls, Friday was a session with no good outcomes and no warning.
