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 market kicks off the new trading week with MannKind (MNKD 1.22%) reporting quarterly results after the market close. MannKind's been trying to get Afrezza, its inhaled insulin, on the market. The stock rallied after an FDA advisory committee voted overwhelmingly in favor of the treatment for patients with diabetes. 

MannKind faces more obstacles before gaining ultimate regulatory clearance. Hopefully MannKind will shed some light on its situation when it reports. 

Tuesday
It's been a good month for video-game developers. The country's two largest publishers rallied after posting better-than-expected results this past Tuesday. A week later, Take-Two Interactive (TTWO 1.71%) steps up with fresh financials.

Take-Two had a monster hit last year with Grand Theft Auto V, but it's not a surprise to see a lull at Take-Two between flagship releases. Analysts see a sharp drop in revenue and profitability when it steps up after Tuesday's close. 

Wednesday
Plug Power
 (PLUG 4.82%) has become a darling in the booming fuel-cell space, and it really came into its own after expanding a deal with Wal-Mart for hydrogen fuel cell charging stations. Things haven't been going so well lately, but that also creates an opportunity. 

Selling 22.6 million shares at $5.50 late last month came at a discount to recent highs, but now that the stock has fallen sharply, the offering doesn't seem so dilutive. Plug Power reports on Wednesday morning. 

Thursday
J.C. Penney (JCPN.Q) steps up with its latest quarterly results on Thursday afternoon. The struggling department store is in a funk, and it's probably not a surprise that Wall Street sees another sharp deficit for the period. 

Sales are starting to stabilize, and the pros see J.C. Penney's top line climbing nearly 3% for the quarter. Naturally we can't claim that the retailer has turned around until losses turn into profits, but at least it's showing signs of bottoming out.

Friday
The final trading day of the week is typically quiet, but that won't stop Canadian Solar (CSIQ -0.37%) from reporting its quarterly results on Friday morning. Canadian Solar offered up an encouraging glimpse on Wednesday, letting investors know that revenue and solar module shipments clocked in ahead of its earlier guidance. We'll be able to fill in all of the blanks on Friday, but this has generally been a strong quarter for the solar-energy specialists that have already reported.
