For investors focused on lucky numbers, it may be notable that the Dow Jones Industrial Average (INDEX: ^DJI) not only topped 13,000 this week but also convincingly held above it. Of course, that's only part of the bigger story, as market indexes continued to march upward this week, building on their already-hefty gains of 2012. In particular, if you're a significant investor in bank and financial stocks, the week probably treated you well, as results from the Federal Reserve's banking stress tests sent financial stocks soaring.

By the time the dust had settled on Friday, the Dow had tacked on 2.4%, while the broader Russell 3000 climbed 2.3%. But all was not well for all industries and stocks.

The big drop in Clear Channel Outdoor's (NYSE: CCO) stock isn't necessarily bad news for investors. What it primarily reflects is that the company went through with its plans to raise a bunch of debt and pay investors a big special dividend. When a company returns cash to shareholders, it typically leads to a commensurate drop in the stock price, as the return of capital reduces the value of the company. But the story may not end there, because some Clear Channel Outdoor investors don't like the way this debt raise and dividend was carried out, and they've sued the company.

Meanwhile, Internet telephony specialist 8x8 (Nasdaq: EGHT) took it on the chin after an early week downgrade from an analyst at B. Riley. The stock was dropped from a buy to a neutral rating, and its target price was slashed from $5.05 to $4.76.

Also among the week's worst performers were Abraxas Petroleum (Nasdaq: AXAS) and Getty Realty (NYSE: GTY).

Abraxas' stock got whacked after the company reported results for the final quarter of 2011. Revenue for the quarter was $16.5 million, up 19% from the prior year. However, the company's bottom line plunged into the red, finishing with a $0.06-per-share loss. On an adjusted basis, the company's loss was $0.01 per share, but that was still easily short of the $0.05 that Wall Street was looking for. The company said that the quarter's results were hurt by pipeline and gas plant capacity issues.

Getty fell victim to a similarly disappointing fourth-quarter report, but that was really only the beginning of investors' concerns. Getty Petroleum Marketing, which accounted for roughly two-thirds of Getty Realty's 2010 revenue, is bankrupt and creating major uncertainty for Getty's business. One very specific and painful impact of that uncertainty was the company's decision to put off its decision on paying a quarterly dividend.
