July 10 (Reuters) - The benchmark S&P 500 briefly crossed the 3,000 points mark for the first time on Wednesday after dovish remarks from Federal Reserve Chairman Jerome Powell bolstered the case for an interest rate cut later this month.
The Nasdaq and the Dow Jones Industrials also scaled all-time highs after Powell said the central bank stands ready to "act as appropriate" to support record U.S. economic growth.
Gains of near 1% each in Amazon.com, Microsoft Corp and Apple Inc were among the biggest boosts to the indexes.
Powell also pointed to economic risks, including persistently weak inflation, slowing global growth and a downturn in business investment, in prepared remarks ahead of his two-day testimony before Congress.
"It could be an insurance cut," David Mazza, head of product at Direxion Investments in New York.
"Meaning just in case things do deteriorate worse or the trade war heats up again, let's pull back the hike we did in December and then begin another wait-and-see approach."
Traders raised the bets of a 50 basis point reduction to 23% following the comments, according to the CME Group's FedWatch tool. They had nearly abandoned hopes of an aggressive reduction while still expecting the first U.S. rate cut since the financial crisis at the July 30-31 meeting.
Alluding to the strong jobs data that tempered hopes of a sharp rate cut at the end of the month, Powell said the report did not fundamentally change the central bank's outlook and that there is important economic data before the meeting.
Investors will now wait for minutes from the Fed's June policy, scheduled to be released at 2 p.m. ET, for more clues on the path forward on interest rates.
At 13:01 p.m. ET, the Dow Jones Industrial Average was up 93.64 points, or 0.35%, at 26,877.13, the S&P 500 was up 15.15 points, or 0.51%, at 2,994.78 and the Nasdaq Composite was up 58.63 points, or 0.72%, at 8,200.35.
Ten of the 11 major S&P sectors were higher, with energy , technology and communication services leading the gainers.
Energy stocks benefited from a jump in oil prices jumped at least 3%.
Shares of banks, which tend to benefit in a higher interest rate environment, retreated 0.54% after Powell's comments. The financial sector shed 0.16%.
Generic drugmaker Mylan NV's shares fell 3.1% after rival Amneal Pharmaceuticals Inc cut its 2019 core earnings forecast.

Advancing issues outnumbered decliners by a 2.36-to-1 ratio on the NYSE and by a 1.53-to-1 ratio on the Nasdaq.
The S&P index recorded 67 new 52-week highs and one new low, while the Nasdaq recorded 91 new highs and 36 new lows. (Reporting by Medha Singh, Manas Mishra and Shreyashi Sanyal in Bengaluru; Editing by Sriraj Kalluvila)
