Stock markets shot higher on Monday and the momentum has continued into Tuesday.
Here are the four things you need to know before the opening bell rings in New York:
1. Stock market overview: U.S. stock futures are pushing up, European markets are rising in early trading and most Asian markets ended with gains.
This follows a mini-rally Monday in the U.S. The Dow Jones industrial average and S&P 500 each jumped 1%, while the Nasdaq rose 1.2%.
2. Crude creeps up: Oil futures continue to regain lost ground and are now trading at their highest levels in more than seven months.
Prices fell to just above $26 a barrel in mid-February -- the lowest since 2003 -- before rebounding.
Crude oil is now trading around $48 per barrel.
