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.

The Dow Jones Industrial Average (DJINDICES:^DJI) has fallen 0.15% as of 3:25 p.m. EST without much in the way of major data to drive stocks. Regulators did approved the Volcker rule, which is supposed to keep big banks from making risky bets with either customer money or their own money. But the rules have been watered down enough that they won't likely have a huge impact on big banks. Dow components JPMorgan Chase and Goldman Sachs are actually up after the regulations passed.

The big banks will still be huge and with complex global operations, and while they may not be able to take the risks seen in past years there's no doubt there will still be plenty of risk from too big to fail.

Verizon has a not-so sunny day
One stock not keeping up with big banks is Verizon Communications (NYSE:VZ), which has fallen 1%. Yesterday, the company announced the acquisition of EdgeCast, a provider of content delivery networks. As fellow Fool Anders Bylund pointed out, the reported $390 million acquisition price is pretty steep for a company with about $100 million in revenue and little profit. But time will tell if the deal pays off.  

Today, the news is that Verizon Wireless is willing to accept unused airwaves for spectrum it's trying to sell. T-Mobile (NASDAQ:TMUS) is the likely bidder for a 700-megahertz A-block spectrum Verizon Wireless is trying to unload; it could offer other spectrum or cash for the asset. T-Mobile raised $3 billion in financing over the past month and has the flexibility to make a deal happen.  

Verizon Wireless could be helping a competitor by selling spectrum to T-Mobile, but the asset isn't doing a lot for Verizon right now. This could be a good deal in the long term, especially if Verizon Wireless can acquire some spectrum it needs to expand coverage.

A buying opportunity
The EdgeCast acquisition is pretty small compared to Verizon's $140 million market cap and the asset sale may actually help the company's balance sheet or spectrum assets. So while Verizon Communications may be lagging the Dow today I think it's still a good buy for investors. The mobile market isn't going anywhere, and a 4.1% dividend yield is a great payback for investors considering the low interest rate environment.
