Nov 30 (Reuters) - U.S. stock index futures edged higher on Wednesday, with those of the Nasdaq rising the most on gains in Tesla shares, while investors treaded cautiously ahead of comments from Federal Reserve Chair Jerome Powell later in day.
Powell's speech will be closely watched for signs of a slowdown in the pace of interest rate hikes by the central bank as well as to assess the general health of the U.S. economy.
"Fed Chair Powell is speaking, but past comments have done little other than chant 'hike, hike, hike'," said Paul Donovan, chief economist, UBS Global Wealth Management.
"Powell has yet to explain the mechanism by which hiking rates is supposed to reduce inflation (which matters to analyzing when rates might peak) ... today's speech should signal a slowing of rate hikes."
Hopes that the Fed will now hike rates in smaller increments and recent data pointing to a mild cooling in prices have positioned the benchmark S&P 500 index for its second straight month of gains.
The Dow Jones Industrial Average has gained nearly 18% in the last two months, while the Nasdaq index has added about 4%.
Traders see the Fed increasing rates by 50 basis points in December, with the rates peaking in June 2023.
