Broadcom reports quarterly results this week with sales expected to jump more than 80% from a year ago, a big test for a US stock market sitting near record highs.

• Broadcom shares fell as worries grew that Washington could put new tariffs on chips, dragging down other chip stocks too.
• Earnings are due September 2 after the US close, with profit per share expected to roughly double and sales to nearly double on AI demand.
• The stock is priced richly compared with rivals, so a miss could hurt, though Wall Street still rates it a buy with an average target above current levels.
• A US jobs report lands September 4, and with inflation still above target, it will shape what the Fed does at its September meeting.

Outlook: Two events this week — Broadcom's numbers and the jobs report — will decide whether the market's run to record highs keeps going.
