Alibaba (BABA) – Alibaba fell 3.8% in the premarket after a Reuters report said the Biden administration was reviewing the China-based company's cloud unit to see if it poses a risk to US national security. The probe is said to focus on how the e-commerce giant stores the data of US clients.

Citrix Systems (CTXS) – Citrix jumped 2.8% in premarket trading following a Bloomberg report saying Elliott Investment Management and Vista Equity Partners were in advanced talks to buy the software company.

23andMe (ME) – The genetic testing company's shares initially rallied 6% in the premarket after announcing that drug maker GlaxoSmithKline had exercised its option to extend a partnership with 23andMe. The company will receive a one-time $50 million payment as part of that agreement. The stock subsequently lost its gains and fell 1.4%.

Goldman Sachs (GS) – Goldman Sachs fell 2.2% in the premarket after reporting a mixed fourth quarter. Goldman earned $10.81 per share for the quarter, compared with a consensus estimate of $11.76, although revenue beat analyst forecasts.
