Apple shares were higher in Monday's premarket after jumping Friday to an intraday high and a record close. The stock gained more than 8% last week.

The Trump administration granted emergency authorization of convalescent plasma to treat hospitalized Covid-19 patients. The announcement came on the eve of the Republican National Convention, and some top health officials have said the clinical data is too weak for approval. President Donald Trump said last week the FDA's decision to hold off on the plasma treatment may be politically motivated.

The Gulf Coast, home to nearly half of the nation's refineries, prepared this week for a potentially devastating hit as two dangerous storms, Marco and Laura, swirled off shore. Officials fear a history-making onslaught of life-threatening wind and flooding along the coast, stretching from Texas to Alabama. The prospect of piggyback hurricanes was reviving memories Katrina, which struck the Gulf Coast 15 years ago, causing as many as 1,800 deaths and catastrophic flooding.
