description: "$Palantir Tech(PLTR.US) rose over two points, $Arm(ARM.US) rose two points, with these two heavyweight stocks in AI software and chip IP steadily climbing; $Quantinuum(QNT.US) rose 12%, with the newly listed quantum stock experiencing even more intense volatility. Valuations for all three are not cheap, relying on their respective high-growth narratives in AI and quantum to support them. $Palantir Tech(PLTR.US) and $Arm(ARM.US) are growth stocks with real performance delivery, while $Quantinuum(QNT.US) is a newly listed quantum target whose volatility is entirely driven by sentiment and liquidity. Despite also being high-growth with high valuation, its certainty of delivery is far lower, requiring extra caution when chasing new listings."
