The stock-market rally that's jumpstarted 2023 is about to fade as the Fed reasserts its resolve in fighting inflation, Morgan Stanley's top stock strategist says

• Stocks are off to a "surprisingly good start" in 2023, but the upside momentum looks set to fizzle, Morgan Stanley said Monday. 
• This week's FOMC meeting may remind investors of the cardinal rule: "Don't Fight the Fed," said strategist Mike Wilson.  
• The investment bank is now leaning more toward its bear case of per-share earnings of $180 for the S&P 500. 

The surge in stocks at the start of 2023 should run out of steam as investors will soon be reminded that the Federal Reserve is continuing to tighten financial conditions to ease still-high inflation, Morgan Stanley said Monday.
