Trump on Tuesday said he wanted to boost the US economy with a "massive" tax relief and make a $1 trillion effort on infrastructure, bets that have helped Wall Street scale new records since the November election.
"Trump came off very Presidential and investors are drawing optimism from the way he delivered the message in his speech," said Andre Bakhos, managing director at Janlyn Capital in Bernardsville, New Jersey.
"Today is just another vote of confidence in Donald Trump being able to do what he says he wants to do."

Banks and industrial stocks, which have benefited the most in the post-election rally, were the biggest gainers on Wednesday. The spike also helped the S&P to break out from the tight trading range the index has been stuck in since Dec. 7.

Gold prices, the CBOE Volatility index and bond proxy sectors of the S&P 500 dropped.
"The specter of higher rates means the economy is doing better," Bakhos said.
