Whisper it quietly, but SpaceX's (SPCX) days in the doldrums may finally be coming to an end. After a dream debut and a nightmare follow-up, the stock is up 2% over the past month. Yet, its most significant trigger in recent times came yesterday, when SPCX shares ended almost 10% higher following the release of Grok 4.6. Today, it has given up some of those gains, but the last five days of trading still show a 23% increase for SPCX stock.
