Energy Vault Holdings is trading at $3.06 (+6.3%) in pre-market, buoyed by the appointment of Nitin Dahiya, a BlackRock veteran, as its new Chief Financial Officer, effective today. The stock is partially rebounding from a 10.3% drop to $2.92 on July 24, which followed profit-taking after a sharp rally sparked by a Citigroup upgrade to Buy with a $5.00 price target.
