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 wireless service providers MetroPCS
So what: According to Bloomberg, Deutsche Telekom may be prowling the deal circuit again with its T-Mobile USA unit following its ill-fated proposed tie-up with AT&T
Now what: Should Deutsche Telekom come through with an offer for MetroPCS, it would have to provide a premium price to entice investors to sell -- and that is exactly what buyers today are counting on as they excitedly push shares up. But buying on takeover rumors is a tough game that can easily lead to heartbreak if no deal ever materializes. This Fool's view is that speculation like this should be left to gamblers.
