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

The new trading week kicks off with Capstone Turbine (NASDAQ:CPST) reporting fresh financials. The maker of microturbine energy systems has been posting narrowing losses as it closes in on profitability, and another smaller deficit is exactly what the market expects after Monday's market close.

Ruckus Wireless (NYSE:RKUS) is one of the many companies reporting on Tuesday. The supplier of wireless systems for the mobile Internet infrastructure market went public at $15 three months ago. The stock tumbled 18% on its first day of trading, but the shares have easily beaten the market since then.

MEMC Electronic Materials (OTC:SUNEQ) chips in on Wednesday. The silicon wafer technology pioneer is expected to post a substantially smaller loss than it did during the same quarter a year earlier.

Waste Management
(NYSE:WM) hopes to clean up on Thursday with its latest quarterly report. The trash hauler's slow yet steady growth has attracted conservative investors over the years. Waste Management's healthy 3.9% yield also helps. Picking up garbage may be a dirty business, but it's big money for the companies that know how to do it right.

Friday is usually quiet on the earnings front, but that won't stop IPG Photonics (NASDAQ:IPGP) from reporting. The top dog in fiber lasers -- offering many advantages over conventional lasers -- is expected to post a quarterly profit of $0.72 a share, well ahead of the $0.64 it rang up last year.
