U.S. stock indexes were wavering between tiny gains and losses in early trading Friday. Losses among technology and consumer-focused companies offset gains by financial and health care stocks. Traders were weighing the potential impact of Hurricane Irma, which slammed into the north Caribbean and was expected to barrel into Florida this weekend.

KEEPING SCORE: The Standard & Poor's 500 index fell 1 point, or 0.1 percent, to 2,463 as of 10:06 a.m. Eastern time. The Dow Jones industrial average gained 26 points, or 0.1 percent, to 21,810. The Nasdaq composite lost 15 points, or 0.2 percent, to 6,382. The Russell 2000 index of smaller-company stocks gave up 3 points, or 0.3 percent, to 1,395.

EYE ON THE STORM: Hurricane Irma, churning with 160 mph winds, left at least 16 people dead and thousands homeless on a devastated string of Caribbean islands and was spinning toward Florida for what could be a catastrophic blow this weekend. Several insurance companies offering coverage for the type of property damage potentially caused by hurricanes continued to slide Friday as traders weighed the prospects of big losses from Irma.

Federated National Holding Co. slid 53 cents, or 5 percent, to $10.03, while HCI Group sank $2.59, or 8.6 percent, to $27.37. Universal Insurance Holdings lost $1.10, or 6.7 percent, to $15.40.

TECH SLUMP: Declines among technology companies were a big drag on the market Friday. Advanced Micro Devices fell 35 cents, or 2.8 percent, to $12.28. Information technology company SAIC declined 18.4 percent after it missed estimates in the second quarter and said its profit margins came under pressure. Its shares slid $13.76 to $60.90.
