Quantum stocks smashed - IONQ down 7%, D-Wave 8%, Rigetti and QUBT drop 10%

[Q]

Quantum computing pure-plays got hit hard this week. IONQ fell roughly 7%, QBTS (D-Wave) dropped 8%, and both RGTI (Rigetti) and QUBT (Quantum Computing Inc) plunged around 10%. The Quantinuum IPO which was supposed to be a sector catalyst opened strong at $68 and slid toward $62, showing early hype was already priced in. The sector-wide selloff follows the broader tech rout and a liquidity rotation into the SpaceX IPO on June 12. Rigetti trades at 592x price-to-sales and D-Wave at 606x, leaving almost no room for any disappointment.

IonQ revenue up 755% year over year and the stock still fell 7%. That is a market telling you the price already included perfection and then some

Quantinuum opening at $68 and sliding to $62 on day one is not a disaster but it is a disappointment. The IPO was supposed to lift the whole sector and instead it drained liquidity from the pure-plays

592x and 606x price-to-sales for Rigetti and D-Wave is indefensible on any traditional valuation framework. These are venture bets dressed up as public equities

QTUM ETF only dipped 0.2% while individual names dropped 7-10%. That spread tells you this is concentrated retail selling in the high-beta names, not institutional de-risking of the sector

D-Wave bookings up 2,000% to $33.4 million is genuinely impressive. That is future revenue being locked in. The stock price today has nothing to do with the business
