Virgin Galactic shares tumbles 8% in premarket trading.

Virgin Galactic shares tumbles 8% in premarket trading.

Virgin Galactic was down 17.3% in last trading day.

Wall Street analysts viewed the flight as a positive for the stock, but it didn’t appear to be enough to change the minds of some of Virgin Galactic’s skeptics.

After the flight returned to earth, Virgin Galactic announced that it would hold a sweepstakes for two tickets for upcoming voyages but did not open ticket sales.

Canaccord Genuity’s Ken Herbert, which has a buy rating on the stock, said that was a sour note for the day.

“While Branson did accompany his return to Earth with an extensive press conference and marketing blitz featuring a musical performance by R&B star Khalid and a pinning of astronaut wings by Canadian astronaut Chris Hadfield, his teased ‘major announcement’ was somewhat disappointing,” the note said.
