Investing.com -- Stocks were mixed on Tuesday as Goldman Sachs weighed on the Dow while tech stocks gained. Here are the midday movers for Jan. 17.

• Goldman Sachs Group Inc (NYSE: GS) shares fell 7.9% after it disappointed on revenue and earnings and reported higher costs and a rising provision for credit losses. Rival investment bank Morgan Stanley (NYSE: MS), however, beat expectations on strong results from its wealth management division. Shares rose 7.8%.
• Roblox Corp (NYSE: RBLX) shares rose 13% after the game-building platform said its daily active users rose by 18% in December from the prior year and revenue (which the company calls bookings) rose 17% to 20%.

• The Travelers Companies Inc (NYSE: TRV) stock fell 5% after the property and casualty insurer said it expects higher catastrophe losses because of recent winter storms, reporting preliminary fourth-quarter results that were below analyst expectations.

• Carvana Co (NYSE: CVNA) shares rose 6% after the used car seller best-known for its car vending machines said it was adopting a poison pill allowing it to carry over losses in one year and deduct them from profit in the future, which is a way to deter people from taking on more than 4.9% of its class A shares.

• Silvergate Capital Corp (NYSE: SI) shares rose 6.4% after the crypto bank reported a $1 billion fourth-quarter loss, which was more than expected; but the company had already signaled its quarter after the collapse of exchange FTX last year. It says it's going to focus on expenses, cutting jobs.
