RKLB and ASTS Priced In Huge Earnings Swings. Here's What Actually Happened

Two Space Stocks, One Earnings Night, One Options Lesson

Rocket Lab (RKLB) and AST SpaceMobile (ASTS) both reported second-quarter 2026 results after the closing bell on August 10. In the sessions beforehand, options traders in both names were paying elevated premiums — a sign the market expected a big move but had no real conviction about which direction. What happened next is a clean, real-world case study in how "implied move" works, and why it isn't a forecast.

What "Implied Move" Actually Means

When traders talk about an "implied move," they're describing what the options market has priced into a stock for a specific event, usually derived from the cost of an at-the-money straddle — buying both a call and a put at the same strike (typically the stock's current price) and expiration. Add the price of the call to the price of the put, divide by the stock price, and you get a rough percentage the market expects the stock to move by expiration, in either direction. It isn't a prediction of up or down — it's a bet on size.

Implied volatility (IV) is the ingredient that drives that straddle price higher or lower. Heading into an earnings report, IV typically climbs as uncertainty builds, then collapses immediately once the news is out — a pattern known as IV crush. That collapse happens whether the stock jumps, drops, or barely moves, because the uncertainty that inflated the premium in the first place has just been resolved.

Rocket Lab: A Beat, a Plunge, and a Round Trip

Rocket Lab's stock had run from roughly $57 in late July to the low $80s heading into its report, helped along by a $266 million U.S. Space Force launch contract and a separate $397 million satellite award. Options pricing reflected that anticipation, with implied volatility running well above the stock's own historical average in the days before the print, according to options-flow data reported by Benzinga.

The actual numbers were solid on the surface: revenue of $234 million, up 62% year-over-year and ahead of the roughly $231.6 million analysts expected, plus a record backlog (signed contracts not yet booked as revenue) north of $2.3 billion. But the per-share loss came in slightly wider than forecast, and CEO Peter Beck told investors the maiden launch window for the company's next-generation Neutron rocket was "narrowing," with slippage toward late 2026 or into 2027 a real possibility (Beck also said the company was still pushing to launch within 2026).

Shares dropped sharply in early trading the next session — down as much as roughly 9% at the premarket low — before clawing almost all of it back to close essentially flat, down less than a tenth of a percent from the prior session.

The lesson: a headline revenue beat, paired with a cautious comment about a single program's timeline, was enough to spark a real intraday plunge — and then the market changed its mind by the closing bell. The options market was pricing in a big move; the stock delivered one, twice, in opposite directions, and still landed close to where it started.

AST SpaceMobile: A Bigger Miss, a Dip, and a Reversal

AST SpaceMobile's report was rougher on paper. Revenue of $31.5 million missed the roughly $34.4 million consensus, and the company posted a GAAP (standard-accounting) loss of $0.77 per share against expectations for a loss closer to $0.29 — a miss driven partly by a one-time $125.9 million charge tied to an "involuntary conversion" (accounting shorthand for a forced write-off of an asset, such as one lost or destroyed).

The company reaffirmed full-year revenue guidance of $150–200 million and pointed to a revenue backlog north of $1.3 billion and pro forma liquidity (cash and available funding, adjusted for recent transactions) above $3.7 billion.

Ahead of the print, the market was pricing an implied move in the neighborhood of 12–14%, based on at-the-money straddle pricing reported by TipRanks. Shares dipped in premarket and early trading — reports put the initial decline at roughly 2–3% — but reversed over the course of the session to close up more than 4% versus the prior day.

That's a wide gap between story and stock. A miss that looked, on paper, like exactly the kind of news that should have driven a double-digit decline instead produced a modest net gain by the close. A trader who bought a straddle expecting a double-digit move in either direction still likely lost money: the stock's net move landed well inside the range that premium was pricing in, even though the intraday path was genuinely volatile.

The Lesson: IV Crush Doesn't Care Who Was "Right," or How Wild the Ride Was

Put the two trades side by side. Rocket Lab beat estimates, sold off sharply, then rallied back to roughly unchanged. AST SpaceMobile missed by a wide margin, dipped, then rallied to a net gain. Neither outcome tracked cleanly with "good news, stock up; bad news, stock down" — and neither one delivered the double-digit net move that elevated implied volatility had priced in, even though both stocks moved a lot along the way. Implied volatility was never claiming to know the direction, or promising that the moves in each direction wouldn't cancel each other out — it was only sizing the uncertainty.

Immediately after each report, IV in both names almost certainly compressed sharply as that uncertainty resolved — the classic IV crush. An option buyer holding calls, puts, or a straddle into either report was fighting a two-front battle: needing a big enough net move in the stock, while racing against the collapse in extrinsic value (the time-and-uncertainty premium built into an option's price, on top of its bare intrinsic worth) that begins the moment the news breaks. A stock that round-trips 9% down and back to flat, or dips and reverses to a net gain, can still leave a straddle holder facing a loss, because it's the final move relative to the premium paid — not the drama along the way — that determines the outcome.

The Risk Every Earnings-Week Options Trade Carries

Buying options ahead of an earnings report means paying a volatility premium that's built to shrink the moment the event passes — win or lose on direction. Selling options into that same event — through strategies like covered calls, cash-secured puts, or credit spreads — flips the risk: a trader collects that elevated premium up front but is exposed if the stock outruns the implied move, as CoreWeave's shareholders and options sellers found out in a separate high-profile earnings reaction the same week.

Any strategy involving leverage, short options, or concentrated single-stock exposure around an event like this can produce losses that exceed the initial premium paid or collected. Neither of the two approaches described here is inherently safer than the other — they carry different, not smaller, risks.

The Takeaway

Elevated implied volatility ahead of an earnings report tells you the market expects a big move — not which way, and not what the net result will be by the close. Rocket Lab and AST SpaceMobile's August reports are a reminder that a stock can whipsaw sharply intraday and still land close to unchanged, or dip on bad news and still finish higher — and that the options premium paid or collected around the event is priced for uncertainty itself, not for any particular outcome.
