As we approach the halfway point for 2012, now's a good time to look back at what's happening with the stocks that interest you. By making sure you know the important things that a company accomplished -- as well as the setbacks it experienced -- you can make a better decision about whether it's a smart investment for your portfolio.

Today, let's take a look at Chimera Investment (NYSE: CIM). The real estate investment trust is in the red-hot mortgage REIT industry, but it takes a slightly different approach from most of its peers, focusing on mortgage-backed securities that aren't backed up by agencies like Fannie Mae and Freddie Mac. Continuing low rates have supported the industry overall, but Chimera hasn't benefited as much as some of its peers. Let's take a quick look at how the stock is doing so far this year.

Why hasn't Chimera climbed higher?
Chimera's 4% gain over the past six months may not seem all that shabby, but it pales in comparison to the larger gains that some of its fellow mortgage REITs have enjoyed. Both Annaly Capital (NYSE: NLY) and American Capital Agency (Nasdaq: AGNC) have generated double-digit percentage gains, with the latter up more than 25% (including dividends).

Much of the disparity comes from Chimera's differing business model. Investing in non-agency debt, Chimera makes up for the relatively higher risk of its securities by taking on less leverage. By contrast, Annaly, American Capital, and ARMOUR Residential (NYSE: ARR) have used far greater leverage but stick to agency-backed mortgage securities. The current interest rate environment favors leverage, explaining some of the outperformance of higher-levered companies.

Moreover, investors appear to be shying away from the stock, perhaps because it has been late in filing two consecutive quarterly reports. Chimera doesn't expect material problems, citing only difficulties in applying generally accepted accounting practice standards to some of its non-agency debt. Still, the delay reinforces the risk of these securities, which can be harder to value than their agency counterparts.

Even though the stock still has a very attractive yield, Chimera's dividend cuts have been problematic. Wall Street analysts are abandoning the stock, with one analyst citing the likelihood of further cuts as the REIT "recognizes losses more aggressively in its subordinated-nonagency investment portfolio."
