* United Airlines gains on upbeat Q2 profit forecast

* Travelers falls after Q1 profit miss

* Indexes down: Dow 0.37%, S&P 0.41%, Nasdaq 0.59%

April 17 (Reuters) -

Wall Street's main indexes fell in choppy trading on Wednesday with chip stocks among the top losers, while downbeat earnings reports from some industry majors, including insurer Travelers, added to the losses.

All three indexes pared initial gains as chip stocks were pressured, with the Philadelphia Semiconductor Index dipping 1.7%. AI giant Nvidia lost 1.7%.

Weighing on the Dow,

The risk sentiment remained fragile after top U.S. central bank officials including Fed Chair Jerome Powell refrained from providing any guidance on when interest rates may be cut. On Tuesday, they said monetary policy needed to be restrictive for longer, dashing investors' hopes for meaningful reductions in borrowing costs this year.

"At this point, the market can handle these (high) rates. It had a little bit of a hiccup and the scare was also combined with the geopolitical problems that we've had in the Middle East," said Joe Saluzzi, partner, co-founder and co-head of equity trading at Themis Trading.

"You put those two together (and you have) a good recipe for a sell-off."

Fed Board Governor Michelle Bowman and Cleveland Fed President Loretta Mester are scheduled to speak later in the day.
