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 market is closed in observance of the Christmas holiday. Don't bother checking online quotes, unless you're holding some overseas stocks.

A better use of your time may be to discreetly box up that dreadful sweater that your aunt gifted you and see if you can exchange it. You'll have to be patient, though, since there's a long line of folks in front of you waiting to return their own ugly sweaters.

Cal-Maine (Nasdaq: CALM) reports on Tuesday.

The yolk was on the country's largest shell egg producer last time out, as Cal-Maine's earnings slipped 35%. Things should be markedly better this time around. Analysts see profit of $0.89 a share, well ahead of the $0.63 a share that Cal-Maine posted a year earlier.

Back in August, Sirius XM Radio (Nasdaq: SIRI) CEO Mel Karmazin told investors that two different Sirius XM 2.0 receivers would hit the market later this year. Well, listeners hoping to access the roughly two dozen new stations and platform upgrades got only one: October's release of Edge.

As we count down the days to the end of 2011, it looks like the second Sirius XM 2.0 receiver -- the more promising Lynx -- won't come this year, even though regulators did recently sign off on the device. On a slow week like this, it's one of the few things still worth watching.

It gets awfully quiet during the final few days of the shortened trading week.

An opportunist would turn to eBay hoping to find some real gems from folks who weren't able to return the gifts they didn't want. Avoid those ugly sweaters.

Now would also be a good time to review where your portfolio stands heading into next year. If you haven't checked out The Motley Fool's top stock for 2012, the clock's ticking. It's a free report, but only for a limited time, so check it out now.

The final trading day of 2011 will find portfolio managers doing some window-dressing. They don't want investors to know that they owned Netflix during its second-half swoon or rode Bank of America all the way down to $5-ish.

It's a silly practice. Who cares what the year-end portfolio list looks like? Investors judge a mutual fund by its actual performance, and that's something that no amount of window dressing can fix.
