NEW YORK, March 4 (Xinhua) -- U.S. stocks posted solid gains for the first week of March, as investors mainly cheered over President Donald Trump's speech to Congress and remarks from Federal Reserve Chair Janet Yellen.
For the week, all three major indices witnessed sizable gains, with the Dow, the S&P 500 and the Nasdaq moving up 0.9 percent, 0.7 percent and 0.4 percent, respectively.
Investor euphoria was ignited by Trump's economic plans, which he described in his first address to a joint session of Congress.
He outlined plans for a 1-trillion-U.S.-dollar infrastructure investment, health care reform, immigration reform and tax relief for businesses and the middle class.
It is widely thought that Trump's address to the Congress was fairly conventional and delivered a desire to move past the turmoil and partisan division rampant in his first month in the White House.
Some analysts believed that the absence of protectionist comments as well as overall tone that was perceived as "presidential" instilled confidence among investors, sending equity markets higher.
Both the S&P 500 and the Nasdaq has their largest one-day rally on Wednesday since Nov. 7, while the Dow posted its best advance since December.
Yellen on Friday signaled that an interest rate hike in this month's monetary policy will likely be appropriate, if the economy progresses in line with officials' expectation.
"At our meeting later this month, the (Federal Open Market) Committee will evaluate whether employment and inflation are continuing to evolve in line with our expectations, in which case a further adjustment of the federal funds rate would likely be appropriate," said Yellen in a speech at the Executives' Club of Chicago.
The Fed is scheduled to hold its monetary policy meeting on March 14-15.
Concerns about a March rate hike are rising in recent weeks after several Fed officials made some hawkish comments on rate hikes.
Federal Reserve Governor Lael Brainard -- a known dove in the central bank's monetary policy committee -- reportedly said Wednesday evening that the Federal Reserve could raise rates "soon," citing an improved global economy.
Market expectations for a March rate hike were around 80 percent, according to the CME Group's FedWatch tool.
