NEW YORK — Wall Street welcomed a surprisingly forthright statement on interest rates from Federal Reserve Chairman Alan Greenspan today, with investors sending stocks higher in acceptance of his tough stand on energy prices and inflation.

Greenspan said the Fed was prepared to abandon a gradual, measured series of rate hikes in favor of larger increases should higher oil prices trigger a more general rise in inflation.

While the prospect of larger and faster rate hikes unnerved Wall Street in the past — and did so again in the early part of today’s session — many investors were cheered by Greenspan’s uncharacteristically straightforward statement, and noted that rate hikes in response to a strong economy fit past patterns of bull markets.

"I think because this statement was so crystal clear and unambiguous, we aren’t seeing the major selling that we saw in the past," said Hugh Johnson, chief investment officer at First Albany Corp. "He really hit this on the head, and there’s no need to parse or interpret this. That makes it a lot easier for the markets to digest and account for."

According to preliminary calculations, the Dow Jones industrial average gained 41.44, or 0.4 percent, to 10,432.52.

Broader stock indicators edged higher after remaining low for most of the session. The Standard & Poor’s 500 index rose 1.70, or 0.2 percent, to 1,142.12, and the Nasdaq composite index was up 2.91, or 0.1 percent, at 2,023.53.

Speaking in London, Greenspan may have signaled that the Fed might raise rates by a half percentage point at the end of the month, instead of the quarter-point raise Wall Street had been expecting.

Although such a warning would have sent stocks skidding a month ago, Wall Street would now welcome a curb on inflation, given that oil prices are still near record-high levels.

And analysts noted that even with a series of rate hikes through the rest of the year, interest rates would still be low compared with past bull markets.

However, trading volume has been uncharacteristically light since mid-May, which historically has not boded well for bull markets. While some of the uncertainty has left Wall Street, particularly around interest rates, some investors may be refraining from further commitments to stocks because of the possibility of a terror attack or another spike in oil prices.

Absent that, the economy remains strong and the Fed’s rate hikes are, for the most part, already factored into stock prices, analysts said.

"I think you absolutely have to like the way the markets are acting after Greenspan spooked us a little," said Jay Suskind, head trader at Ryan Beck & Co. "The only thing bothering me is the light volume. There’s still not a lot of interest there, but since there’s no real bad news, we can drift like this and even drift to the upside over the summer."
