Wall Street This Week: Apple Streams, Twitter Searches

From the company behind iTunes trying to regain its relevance in digital music to a change at the top of a social media giant, here are some of the things that will help shape the week that lies ahead on Wall Street.

Monday -- Flunking Out Online

The new trading week kicks off with Web-based campus operator Apollo Group (APOL) reporting its latest quarter's results after the market close. Apollo Group is the company behind the University of Phoenix.

These have been challenging times for post-secondary educators. Enrollments are down -- for the industry in general and Apollo in particular -- as the public questions the effectiveness of Internet curricula. Apollo Group is expected to see revenue and earnings fall sharply during the quarter relative to the same period the year before. That's not going to give it a passing grade.

Tuesday -- Tune In

Apple (AAPL) launches Apple Music on Tuesday. The new premium streaming platform is going to attract attention. Apple's offering three free months as a trial subscription, as long as users agree to be automatically billed $9.99 a month for the service beyond that unless they cancel during the trial.

It reversed its stance after being called out by Taylor Swift, who threatened to pull her latest release from Apple Music if it forced artists to bear the brunt of Apple's customer acquisition costs.

Tech giants have been trying to make a big splash in streaming services for years, but they have largely struggled. Apple Music is the latest arrow in the quiver of tech behemoths, and if it doesn't pan out it could be the last.

Wednesday -- A Resume in 140 Characters or Less

Dick Costolo steps down as CEO of Twitter (TWTR) on Wednesday and co-founder Jack Dorsey will step in as interim CEO until the social media darling finds a new leader. Twitter has struggled after its initial pop following its late 2013 IPO. The stock has surrendered more than half of its value since peaking nearly two years ago, and a change at the helm isn't exactly a surprise given the stock's disappointing performance.

Thursday -- Checkered Flag

International Speedway (ISCA) comes around the corner to post quarterly results Thursday. International Speedway is the motorsports promoter behind several leading car racing tracks, including Daytona and Talladega.

Motorsports doesn't seem to be a struggling niche, but analysts see International Speedway clocking in with lower revenue and earnings than it did during the same quarter a year earlier.

Friday -- No Fireworks on Wall Street

The market exchanges are closed Friday in observance of Saturday's Independence Day. This should be a big weekend at the corner multiplex. "Terminator Genisys" and "Magic Mike XXL" are two of the bigger movies opening Friday, but the more successful recent releases will likely also draw big audiences during the holiday weekend.
