NEW YORK, Sept 20 (Reuters) -Wall Street slid from the previous session's record highs and the dollar steadied on Friday as the market knuckled down to the start of a rate reducing cycle that began with a mid-week jumbo cut by the U.S. Federal Reserve.

With the long-awaited decision made, markets mulled the motivations for the move, which Fed Chair Jerome Powell indicated should be seen as safeguarding a resilient economy, rather than an emergency response to weaker jobs data.

All three major U.S. stock indexes posted early losses but have still set a course to log weekly gains thanks to all-time highs hit on Thursday as buyers piled in to riskier assets.

Fed funds futures have priced in about 72 bps of cuts by the end of this year and 195 bps of cuts by October 2025.

"What Chairman Powell said was that they're carefully watching the labour market, and if it slows too much they're prepared to act," said Marija Veitmane, head of equity research at State Street Global Markets.

"Powell also said that he doesn't see the labour market as inflationary - that's a positive message for risky assets."

The blue-chip Dow Jones Industrial Average .DJI fell 0.15%, to 41,963.50, the S&P 500 .SPX shed 0.34%, to 5,693.95 and the Nasdaq Composite .IXIC fell 0.42%, to 17,938.72.

Some volatility is expected during the day, as options and futures linked to indexes and individual stocks are set to expire simultaneously, in an event called "triple witching" that falls on the third Friday of the last month of the quarter.

The MSCI index of world stocks .MIWD00000PUS drooped 0.32%, after Thursday's 1.6% jump took it to a record high. It was still headed for a weekly rise.

Utilities outperformed, with the .SPLRCU boosted by Constellation Energy CEG.O whose stock soared more than 14% on news of a deal with MicrosoftMSFT.O to reopen part of a mothballed nuclear plant to power artificial intelligence projects.
