Here are five things you must know for Tuesday, Aug. 28:

1. -- Stocks Rise as U.S. and Mexico Reach Trade Deal

U.S. stock futures rose on Tuesday, Aug. 28, indicating a third consecutive record-setting session for Wall Street, and global stocks edged higher as investors reacted to news of a possible NAFTA overhaul that could lead to the end of trade disputes between the U.S., China and the European Union.

Contracts tied to the Dow Jones Industrial Average I:DJI  rose 45 points on Tuesday, futures for the S&P 500 I:GSPC  were up 4 points, and Nasdaq I:IXIC futures gained 22.50 points. The Dow on Monday, Aug. 27, rose 259 points, or 1.01%, to close at 26,049. The S&P 500 rose 0.77% to 2896.74, its second record high in as many trading days. The Nasdaq gained 0.91% on Monday to end at 8,017.90, also a record.

Donald Trump announced a new agreement on trade Monday with Mexico that will both replace the current NAFTA pact - which covers an annual $1 trillion in trade - and leave Canada, the U.S.'s second-largest trading partner, without a bespoke deal.

The fact that Mexico appeared ready to comply with several White House demands, including wage limits and "country of origin rules" in the auto sector, has investors hoping that Trump can work similar deals with Brussels and Beijing, moves hat would ease the current trade tensions and kick-start economic growth into the final months of the year.

John Schnatter, the ousted founder of Papa John's International Inc. (PZZA) - Get Report , said in a letter to franchisees on Monday that the company's poor performance was caused by "rot at the top" and he singled out CEO Steve Ritchie.
