U.S. President Donald Trump has taken credit for the stock market's gains during his nearly two years in the White House, and those claims are reasonable given the impact of tax cuts and pro-business policies on investor sentiment.

The S&P 500 has risen 28 percent since Trump's election in November 2016 to the eve of congressional midterm elections on Tuesday. This surpasses the market's performance over the same time frame under any other president in the past 64 years. Under President Dwight Eisenhower, the S&P 500 rose 29 percent from his election in November 1952 through November 1954.

Sweeping corporate tax cuts, an initiative driven by Trump, supercharged U.S. companies' earnings and helped lift the cash-rich technology sector. The Republican party last year passed the biggest overhaul of the U.S. tax code in over 30 years, boosting U.S. corporate earnings.

Still, other sectors that could have been expected to benefit strongly from a Trump presidency have lagged. Indeed, the individual stocks that have gained and lost the most during his reign have little discernable link to Trump's presidency.

How the market shakes out in the final two years of Trump's presidency will probably be influenced by Tuesday's elections. Analysts expect pressure on stocks if Democrats gain control of the House of Representatives and a sharper downward reaction if they sweep the House and Senate.

On the contrary, if Republicans hold their ground, stocks could gain further, with hopes of more tax reform ahead. urn:newsml:reuters.com:*:nL2N1WE1Q2

The following graphics show how the Trump presidency has played out on a macro and micro level:

Trump's strong stock market record has been maintained even after a recent pullback on Wall Street as worries about trade battles, inflation and rising interest rates have increased caution among investors. Starting in 2010 under President Barack Obama as the world recovered from the financial crisis, the S&P 500 has enjoyed its longest bull market in history.

With more than half of Trump's presidency still to come, how the market will perform over his whole term is unknown. Democratic President Bill Clinton saw the S&P 500 triple during his two terms in the White House. 

Average S&P 500 company earnings per share are on track to rise 24 percent this year, the strongest annual gain in eight years, according to IBES data from Refinitiv.

Investor confidence stemming from the tax cuts and Trump's other business-friendly policies so far have more than made up for ongoing worries on Wall Street that his trade conflict with China is hurting the U.S. economy, and that it could become worse.

The tax cuts also led Apple AAPL.O and other multinationals in the technology sector to repatriate billions of dollars in profits held overseas, some of which went toward buying back stock and sending Wall Street higher.

The S&P 500 information technology index .SPLRCT has gained 51 percent since Trump's election. Financials .SPSY , which benefited from Trump's deregulation of the banking industry, have climbed 34 percent since Nov 8, 2016.
