From 6% After Hours to 20% by Mid-Morning
Yahoo Finance data showed CRWV near $58.44 at about 10:25 a.m. ET, up about 19.9% from Tuesday's $48.73 close, after trading between $53.81 and $59.16. Volume had already topped 64 million shares. CNBC reported the stock up as much as 20%, and quoted CEO Michael Intrator: "Demand for the infrastructure is and remains overwhelming."
The numbers behind the move were already out Tuesday: revenue of $3.66 billion, a backlog of about $132.5 billion and a raised full-year revenue outlook. What changed overnight was how the market weighed them. CNBC noted that CoreWeave has faced questions this month over its financing, including credit default swap spreads that had widened past 11%.
The Implied Move Was Roughly 18%. The Stock Did About 20%.
Before the report, the November 13 at-the-money straddle priced a move of roughly 18%, per Cboe data cited in our Tuesday article. A 19.9% gain lands just beyond that range. That's a reminder that an implied move is a price for an expected range, not a ceiling.
Even so, the event premium came out of the options. Cboe delayed quotes at 10:24 a.m. ET showed:
Calls dominated, at about 200,000 contracts against 108,000 puts. The busiest line was the November 13 $60 call, at about 33,400 contracts and $1.87 bid / $1.93 ask, followed by the November 20 $60 call at about 12,600.
Who Gained When the Stock Beat the Straddle
A long straddle bought Tuesday at around 18% of the stock price would have gained, since the move exceeded its cost, though the drop in implied volatility took back part of the value left in the options. A short straddle seller faced the reverse: the stock moved past the upper breakeven, so falling volatility didn't offset the directional loss. Long calls captured most of the move. Short calls without stock or a hedge took the worst of it.
That's the trade-off in earnings volatility selling. Most reports land inside the implied move, but the ones that don't can wipe out several small gains.
The Rally Spread Across Chips
The move didn't stay with CoreWeave. Investopedia reported Broadcom, Intel, Micron and Marvell each up about 6% early, and the Yahoo Finance live blog tied the chip rally to CoreWeave's results. Nvidia was also rebounding after two losing sessions.
By about 10:25 a.m. ET, Yahoo data showed SOXX up about 4.5% near $153.12, SMH up about 3.7%, Micron up about 9.8% near $795.91 and Broadcom up about 5%. Cboe data showed SOXX 30-day implied volatility near 49.4%, down about 3 points, and Micron's near 66.2%, down about 2.7 points, per Cboe's MU quotes. Rallies often come with lower implied volatility, because demand for downside protection eases as prices rise.
