U.S. stock indexes ended mixed after Nvidia, Palantir and other superstar stocks pared most of their steep losses from the morning.

Asian shares were mostly higher on Thursday after a mixed finish on Wall Street, where shares in Nvidia, Palantir and other superstar stocks pared their earlier steep losses.

Citron Research published a scathing report on Palantir, saying that even if the defense name traded at $40 — 75 percent below current levels — it would still be “expensive” relative to history.
