Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.

What: Shares of data center services specialist Equinix (Nasdaq: EQIX) jumped as much as 14.6% overnight, and even the after-hours action was raucous.

So what: Given recent events in the networking industry, you'd be forgiven for thinking that Equinix got a buyout offer today. But it's actually simpler than that: This was a classic beat-and-raise performance in the first quarter, followed by the announcement of an ambitious expansion plan across Europe and the USA.

Now what: With Terremark and SAVVIS (Nasdaq: SVVS) off the table and folded into much larger telecom and data networks, Equinix is left as the largest network-neutral service provider in its industry. That's actually a pretty comfortable place to be, as vendor-agnostic enterprise software maker TIBCO Systems (Nasdaq: TIBX) will tell you. Equinix is using this quarter's success to invest in future growth, which is a perfectly reasonable thing to do.
