If you're reading this right now, you probably didn't win the $429.6 million Powerball.

Thankfully, there are other ways in this world to make a buck. For example, smart investing!

Here are the five things you need to know before the opening bell rings in New York:

1. Saudi surprise: Oil prices are jumping by about 2% to trade above $45 per barrel after Saudi Arabia ousted long-serving oil minister Ali al-Naimi. He was replaced by Khalid al-Falih, the chairman of state-owned oil firm Saudi Aramco.

The top-level job shuffle is seen as a power move by deputy crown prince Mohamed bin Salman, who is working to consolidate his grip on the economy.

Oil makes up 87% of Saudi Arabia's revenues -- but bin Salman is trying to diversify the economy.

2. Earnings: A number of companies are reporting quarterly results Monday morning, including Sotheby's (BID) and Tyson Foods (TSN).

Hertz (HTZ), SolarCity (SCTY) and Liberty Global (LILA) are all reporting after the close.

3. On alert for Panama Papers: The financial world is watching for the 2 p.m. ET release of the Panama Papers search database, which is expected to detail ties between 368,000 people and 300,000 offshore entities.

The publication of the Panama Papers last month sparked global shock waves. News reports based on a stash of documents taken from an international law firm alleged that top officials around the world hid wealth in secret offshore companies. The claims were widely disputed by people named in the documents.

This new database will allow people to see for themselves which politicians, celebrities and business executives allegedly kept secret shell companies that were exposed in the Panama Papers.

4. Global stock market overview: U.S. stock futures are sitting pretty ahead of the open. Stocks are set to open roughly where they left off on Friday.

Many European markets are rising by about 1% in early trading.

Asian markets ended the day with mixed results. Chinese stock markets were particularly weak following the release of worse-than-expected Chinese export data in April.

5. Weekly market recap: Stock markets didn't seem to have have much direction last week and ultimately lost ground over the five trading days.

The Dow Jones industrial average slipped 0.2%, the S&P 500 declined by 0.4% and the Nasdaq dropped by 0.8%.
