President-elect Donald Trump takes center stage with his first postelection news conference Wednesday, and traders are looking for more details around the promises that have helped drive the Dow up 9 percent since Election Day.

Another test for the rally will be the start of fourth-quarter earning seasons, and first up are financials, the leaders of the Trump rally with a near 18 percent gain since Nov. 8. JPMorgan Chase (JPM), Bank of America (BAC), Wells Fargo (WFC), PNC Financial (PNC) and others report Friday.

Earnings for theS&P 500 (^GSPC) are expected to increase by 6.1 percent in the fourth quarter, but the S&P financial sector earnings are expected to have the biggest gains, with earnings up 15.7 percent, according to Thomson Reuters.

The sector has bounced hard on the prospect of higher interest rates and a steeper yield curve, which would help bank profitability. The stocks also are rising on Trump's vow to end excess regulation. Besides banks, names like Goldman Sachs (GS) and Morgan Stanley (MS) are in that financial group and both are trading at near decade highs. Goldman is up 35 percent since the election, and has been leading the Dow.

"I suspect earnings are going to be pretty darn good, but the problem is expectations are going up too," said James Paulsen, chief investment strategist at Wells Capital. "Given the movement in some of these stock prices, you better hope they're outperforming expectations."

President-elect Trump has been credited with being a major catalyst behind the market's rally since election day, though some analysts say the market and economy were already poised for improvement.

"Right now the market has been floating on the illusion of optimism, and does that turn into a false sense of security?" said Scott Redler, partner with T3Live.com.

Redler said Trump sparked the rally when he spoke in the early hours of Nov. 9. That victory speech has been credited with turning collapsing stock futures into a two-month rally. Trump focused on the pro-growth programs, like infrastructure spending and corporate tax breaks, that Wall Street has latched on to. He did not dwell on tariffs or trade proposals that had made Wall Street nervous before the election and are still a concern for some strategists.

"All eyes will be on [President Barack] Obama's farewell speech Tuesday and then President-elect Trump's first press conference on Wednesday," said Redler. "We'll be trying to figure out what his tone is like. It will be a kind of pre-game for the inauguration. Traders would like the tone to be like he had in his election speech when he was claiming victory, versus what we've seen in the last few sessions."
