There's never a dull week on Wall Street. Let's go over some of the news that will shape the week to come.

Monday
The first trading day of the week kicks off with GT Advanced Technologies (NASDAQ: GTAT) reporting quarterly results on Monday afternoon. The solar and LED equipment maker is expected to return to profitability after posting back-to-back quarterly losses.

There are plenty of skeptics out there. GT Advanced Technologies' short interest accounts for more than 40% of the shares outstanding. Just imagine the short squeeze we'll see if there's a strong report.

Tuesday
Nuance Communications (NUAN) steps up on Tuesday afternoon with fresh financials. Investors haven't been liking what they've heard out of the speech-recognition specialist, and that's why Nuance is trading near its 52-week low.

Analysts see a profit of $0.32 a share, well short of the $0.45 it rang up a year earlier. It could be worse than that. Nuance has come up short on the bottom line in its two previous quarters.

Wednesday
Tesla Motors (TSLA -1.11%) is revving up for its latest quarterly results. The market darling surprised investors with a quarterly profit last time out, but it's not likely to repeat that feat this time around.

This doesn't mean Tesla's in trouble. Demand for its Model S all-electric sedan has been high, and the leading-edge carmaker is handing off its costly cars as quickly as they roll off the assembly line. The only danger that investors face is heightened expectations. After seeing its shares roughly quadruple so far in 2013, it's going to require a monster report to keep the shares going.

Thursday
Capstone Turbine (CPST) reports on Thursday. The maker of micro-turbines isn't profitable at the moment, but losses have been narrowing and revenue has been growing at a double-digit percentage clip.

Capstone Turbine closed out its most recent quarter with a record $148.9 million in product backlog, suggesting that healthy revenue growth will continue in the near term.

Friday
The market is usually quiet on Fridays, but that won't stop James River Coal (NASDAQ: JRCC) from reporting.

Coal has been out of favor lately, and James River Coal has shed roughly 90% of its value over the past two years. As a leading coal producer in Central Appalachia and the Illinois Basin, James River has had a hard time turning a profit on its metallurgical, bituminous steam, and industrial-grade coal. The inevitable shakeout will help the players still standing, but will James River Coal make the cut?

Analysts see another steep deficit on a brutal 30% drop in revenue.
