Welcome to Seeking Alpha's Wall Street Lunch, our afternoon update on today's market action, news, and analysis.

Good afternoon. Today is Wednesday, December 4th, and I'm your host, Kim Khan. Our top story so far.

United Healthcare CEO, Brian Thompson, was shot and killed this morning outside a Midtown Manhattan

Hotel, where he was scheduled to speak at the company's annual investor conference.

tracker record of indicating what official numbers will be, though. In addition, the November

months that the index signaled growth. Wells Fargo economists say service sector prices are

clouding the outlook for the Fed. The challenge confronting policymakers is how to slow growth in the service sector

without completely extinguishing it and without keeping policy too restricted

for manufacturing and other rate-sensitive parts of the economy, they said.

with implications for prices.
