Moderna COVID-19 vaccine receives full FDA approval:

Moderna (MRNA  ) shares rose on Monday after the company received full approval for its COVID-19 vaccine, named Spikevax, from the U.S. Food and Drug Administration (FDA).

The mRNA-based vaccine was previously available in the U.S. under Emergency Use Authorization since Dec. 2020. Moderna now joins Pfizer (PFE  )-BioNTech's (BNTX  ) COVID vaccine which received full FDA approval back in August.

Tesla set to "Outperform" according to Credit Suisse upgrade:

Credit Suisse (CS  ) sees Tesla's (TLSA  ) recent slump as the perfect buying opportunity, upgrading the stock to "outperform" and setting a new price target of $1,025.

Analyst Dan Levy wrote in a note on Monday: "Tesla has surprised to the upside on margins, in large part driven by cost reductions; we believe the strong margins are sustainable," and that the firm believes, "legacy OEMs are taking clear steps to transitioning to an EV world, yet we expect Tesla to maintain a lead for the foreseeable future."

"Up until now Tesla margins have largely been a function of auto hardware sales, with some modest benefits of software," Levy added. "However, as Tesla releases more FSD (Full Self-Drive) features and unlocks more deferred revenue (which likely flows through at 100% contribution margin), Tesla should see incremental margin benefit."
