If you're feeling good about the market, you're not alone. Take my hand as we go over some of this week's more uplifting headlines.

1. That's 35 million listeners to you
We should probably stop limiting our count of the Sirius XM Radio (NASDAQ:SIRI) audience to its 18.5 million subscribers. The satellite-radio provider revealed the results of an Arbitron study, which estimated that there are 35 million Sirius and XM listeners, with 32 million people tuning in at least weekly.

Issuing the release yesterday was a no-brainer move for Sirius XM. It also highlighted the attractiveness of its audience, by pointing out that 24% of its listeners have household incomes greater than $150,000, compared with just a 9% sliver for AM/FM listeners.

Drawing sponsors has been a surprising Sirius XM weakness, given its CEO's terrestrial-radio pedigree. Net advertising revenue at the company through the first nine months of 2009 fell by 31%. Sure, Sirius XM is appreciated primarily for its commercial-free music programming, but it also has plenty of ad-backed talk content as well. If anything, this Arbitron study should open the eyes -- and pocketbooks -- of potential marketers looking to reach audiences with disposable income to spend.

2. Chip off the old Chipotle
Just because Chipotle Mexican Grill (NYSE:CMG) sees flat comps this year, that doesn't mean the burrito chain is no longer a growth story. For starters, there's the eatery's heady expansion to cheer on. It expects to add as many as 130 new locations this year. Margin expansion has been another Chipotle trademark, so investors may very well still be wowed by its bottom-line growth.

However, the company also shared a few growth initiatives during this week's Cowen and Company Consumer Conference. For starters, it's scouting for overseas locations in France and Germany. It's been impressed by its first international opening in Toronto, and it's readying its first London store for an April opening.

Chipotle is also testing a prototype restaurant with a smaller kitchen. Shaving its kitchen size by 25% results in $25,000 in initial development savings and lower energy costs after that. The slightly smaller footprint will allow Chipotle to penetrate more deeply into markets, while still maintaining its envy-of-the-industry cash-on-cash returns of 35% a year on its development costs.

3. And Wii makes three
Netflix (NASDAQ:NFLX) finally went for the trifecta, by making its online streaming service available on all three video-game consoles.

It was only natural to see Netflix go with the Xbox first in the fall of 2008, since Netflix CEO Reed Hastings sits on Microsoft's (NASDAQ:MSFT) board. Offering the Xbox roughly a year of exclusivity made sense, since Xbox Live is far more established than the PS3 and Wii gaming platforms.

Online streaming for Netflix subscribers on Sony's (NYSE:SNE) PS3 consoles went into effect late last year, and this week the DVD-rental giant announced its arrival on the Wii.

It's fair to say that Nintendo's (OTC BB: NTDOY.PK) Wii isn't targeted to celluloid buffs. It's the only gaming console that doesn't play DVDs. However, the Wii has been portrayed as being more friendly across generations, with its family-friendly diversions for young gamers and its workout systems for parents and grandparents. Enhancing the value of the Wii to Netflix subscribers is a big win.

4. Let's have some fund
Stocks and bonds don't go up every week. But mutual funds have a pretty impressive streak going on, in terms of which way the investments and redemptions are flowing. According to the Investment Company Institute, long-term mutual funds have experienced 43 consecutive weeks of net inflows.

A total of $427 billion in inflows has taken place during the streak. Pair that up with asset-boosting returns on most funds last year, and you have a welcome one-two punch for an industry that relies on management fees based on asset bases. If you've ever wanted to own stock in any of the handful of publicly traded mutual-fund families, the climate couldn't get any better if the valuations are fair.

5. Banking on Google bites back
IT-outsourcing specialist Infosys (NASDAQ:INFY) hit a 52-week high this week after posting better-than-expected fourth-quarter results.

Companies top the pros all the time, but Infosys is an India-based call-center operator, primarily for financial-services institutions. Wasn't this sector in the tank? The clincher is that Infosys crushed Wall Street profit targets during each and every 2009 quarter.

I guess outsourcing is in.
