Virgin Galactic’s wild roller coaster ride on Wall Street continued over the past week as Richard Branson’s spaceline marked five months as a publicly traded company and 13 months since the last launch of its SpaceShipTwo suborbital tourism vehicle.

Since debuting on the New York Stock Exchange at $12 last Oct. 28, the stock soared to a high of $42.49 on Feb. 20 before sinking to $10.49 on March 19. Over the past week, the stock has risen again; it reached $14.68 in after-hours trading on Monday.
