President Biden doesn't publicly talk about stock market performance during his time in office, but he's slightly outpacing his more boastful predecessor.

By the numbers: The S&P 500 increased by 4.6% during the first 50 trading days of the Biden presidency, from market close on Jan. 19 to market close on March 31. Trump's first 5-day bump was 4.4%, whereas President Obama was down 6.1%.

• Biden also outperformed Trump in terms of Dow Jones Industrial Average performance, but Trump topped Biden on NASDAQ Composite performance.

Between the lines: Every president inherits different economic conditions.

• Biden arrived near the end of a devastating pandemic, with business optimism growing.
• Trump took office amidst a years-long bull market.
• Obama was inaugurated with the economy still in freefall from the 2008 financial crisis.
