2. Brian Moynihan’s chairman title hangs in the balance.

Bank of America (BAC) shareholders will cast their ballots today to decide whether the company’s board had the right to name Brian Moynihan both the CEO and chairman of the board. Back in 2009, shareholders had voted to split the two positions, but last year the board decided to recombine the roles. If shareholders decide to break up the two titles once again, Moynihan will have to choose only one.

3. General Mills updates investors.

The maker of Cheerios and Betty Crocker dessert mixes will report its first-quarter earnings. General Mills (GIS) has reported better-than-expected earnings report for three consecutive quarters so far–and that’s expected to continue. The company said it will sell its Green Giant frozen food and Le Sueur canned vegetable brands to B&G Foods for about $765 million. Meanwhile, it’s focused on revamping its core products, removing artificial colors and flavors from its cereals and launching new gluten-free options.

Cruisers and investors alike will be listening carefully for any update on when the company plans to launch its service to Cuba, which Carnival plans to make part of its new social impact-focused Fathom brand.

5. A look at housing prices.

The U.S. Federal Housing Finance Agency will release its home price index for July at 9 a.m. ET. Many home owners may be hoping for a slight uptick after month-over-month prices remained mostly flat in June, a sign that the market is holding steady after a rough past few years. Economists expect home prices to be up 0.4% in July, slightly above the 0.2% boost in June.
