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. Chrome wasn't built in a slay
Google (Nasdaq: GOOG) is announcing a Chrome-branded operating system, in a move that might send shivers down Microsoft 's (Nasdaq: MSFT) spine.

Unless you’re Mr. Softy, you have to love Google's timing. This announcement comes just as the pre-order deadline for discounted upgrade copies of Windows 7 draws near. Microsoft's well-received successor to the not-so-well-received Vista will be released in a few months.

Still, Chrome can't unseat Windows right away -- if ever. Google's Chrome browser is a worthy Web-surfer, but it has about as much share in the browser space as Microsoft's Zune has in portable media players.

Microsoft has also been able to keep free open-source operating systems at bay, despite the best intentions of Linux and its various offshoots, such as Ubuntu. The difference here is that Google has something to prove -- and the deep pockets to prove it.

Big G is about to get even bigger.

2. Boning up on Amgen  
The news keeps getting better for denosumab, Amgen 's (Nasdaq: AMGN) promising osteoporosis treatment that's barreling toward FDA approval. A clinical test shows that denosumab is better than an existing drug on the market in treating the bones of breast-cancer patients in cases where the ailment spreads to the bones.

Amgen is no stranger to blockbuster drugs. It's milked its biotech mastery with Epogen, Neupogen, and more. Since billion-dollar drugs eventually go off-patent, it's important to keep the pipeline flowing. With denosumab in the final phase of clinical trials, it appears as if Amgen has another hit on its hands.

3. Et tu, eBay?
The swagger is back at the world's leading -- and occasionally reeling -- auction site. A pair of brokerage reports indicate that eBay 's (Nasdaq: EBAY) troublesome marketplace business is stabilizing.

Since eBay's PayPal and Skype appendages are doing well, the only thing that's been holding the company back over the past few years has been the gradual fade of eBay.com itself.

Neither brokerage-firm analyst expects an immediate turnaround at the company, but the mere fact that eBay's flagship auction business has finally hit bottom is comforting. The pressure is on, especially since eBay plans to unload Skype. Can it be? After alienating power sellers and confusing active buyers, eBay may finally be giving its users what they want.
