Thursday's report will benefit from Amazon's recent momentum and also from Prime Day shifting to the second quarter of this year. Amazon's here to provide some balance to Sirius XM. Unlike Sirius XM with its sub-$7 share price, Amazon's trading well into the four figures. Naturally you would have to buy Amazon through a broker that allows fractional shares. Amazon's not cheap by most measuring sticks, but it could be higher after another blowout quarterly performance by the end of the week.
