U.S. stock futures were pointing to a strong rebound Wednesday on Wall Street as moderate Democrat Joe Biden scored major Super Tuesday wins in the race for his party's presidential nomination. The implied gain of over 500 points for the Dow Jones Industrial Average at the open would largely reverse Tuesday's 785 point decline. The Dow was all over the map, with an intraday gain of nearly 400 points and loss of almost 1,000 points after Tuesday morning's emergency 0.5% interest rate cut by the Federal Reserve failed to temper concerns of slower economic growth due to the coronavirus outbreak. The Dow closed in a correction, down over 12% since record highs on Feb. 12. A correction is defined as a decline of at least 10% from recent 52-week highs. ADP's private-sector jobs report showed better-than-expected payroll growth of 183,000 positions in February. On Friday, the government issues its February employment report.

2. 10-year Treasury yield around 1% after Tuesday's historic plunge

Investors are still piling into bonds early Wednesday, but the 10-year Treasury yield went above 1%, a threshold it breached to the downside for the first time ever on Tuesday. Other global central banks, including the European Central Bank and the Bank of England, are expected to follow the Fed and announce stimulus measures in coming days. However, there's a debate in the market over whether monetary policy can really help boost economic growth if people worried about catching the coronavirus won't leave their homes to go out to eat or to travel.

3. Coronavirus mortality rate rises as confirmed cases around the globe continue to climb

The World Health Organization said the mortality rate for coronavirus is 3.4% globally, higher than previous estimates of about 2%. By comparison, the 2002-2003 SARS outbreak killed nearly 1 in 10 infected people. The common flu in the U.S. has a mortality rate of 0.1%. More than 93,000 coronavirus cases have been confirmed worldwide, including 3,198 deaths, though the vast majority of infections and deaths are still in China, where the virus originated in late December. Italy now has the most cases of coronavirus outside Asia, with over 2,500 cases and 79 deaths, South Korea has the most cases outside China, with 5,328 infections and 32.
