Oct 5 (Reuters) - U.S. stocks were set to open slightly higher on Thursday after data showed the U.S. trade deficit narrowed and the number of Americans filing for unemployment benefits fell more than expected last week.
The Commerce Department said on Thursday the trade gap declined 2.7 percent to $42.4 billion, suggesting that trade could help soften the blow on the economy from hurricanes Harvey and Irma.
Initial claims for state unemployment benefits dropped 12,000 to a seasonally adjusted 260,000 for the week ended Sept. 30, the Labor Department said on Thursday.
The weekly data is a precursor to the more comprehensive monthly jobs report, which is due on Friday.
Markets have been on a rally this week, with the three major indexes touching record-highs for the third straight day on Wednesday.

Third-quarters earnings of S&P 500 companies are expected to rise 5.5 percent from a year earlier, according to Thomson Reuters data. That would be down from double-digit growth in the first two quarters, but many strategists are optimistic results will be better than expected.
