What happened at Chimera this year?
What a difference a year makes. Chimera's stock didn't have a three-peat banner year after the 20%-plus gains of 2009 and 2010. But investors don't buy mortgage REITs for stock appreciation -- they're after yields. Chimera's payouts partially compensated for its stock decline, though quarterly payouts have fallen from $0.17 to $0.11 since last December, largely because of big losses on investments.

But on the whole, residential mortgage REITs like Chimera have hit a bonanza over the past few years. As the Federal Reserve lowered overnight interest rates to nearly 0% to support the struggling economy, Chimera's cost of borrowing has held much lower than it otherwise would have, pushing up its interest-rate spread -- the difference between the interest rate it collects and the rate it borrows -- to a whopping 4.9% as of last quarter. The interest-rate tailwind was the key reason I purchased shares of the stock for the real-money publicly facing Dada Portfolio that I co-manage.

However, Chimera follows a slightly different model from most other residential mortgage REITs. By taking more flexibility with the assets it buys, it can achieve even higher interest-rate spreads than its competitors. It compensates for this higher level of risk by using less leverage:

In the hands of a capable management team, such an approach allows a REIT to take advantage of mispricings in the market. In the hands of bumblers, the style can hasten a company's demise.

Chimera barely issued any stock in 2011, a far cry from the $1.3 billion raised in the last quarter of 2010 alone. Its stock has traded for an average of just 0.95 times book value. To not issue stock in today's trigger-happy environment shows unusual restraint.

Steady as she goes
For 2011, Chimera took some light blows and ratcheted down its risk in response to the financial storm blowing through Europe. The Fed reiterated that it's going to hold rates low for some time as the economy slowly recovers. Assuming lenders continue to consider Chimera a solid borrower, the trouble brewing in financial markets might present fresh bargains for this opportunistic REIT.

I think Chimera could see some good places to invest in the new year, but our analysts have selected a different stock that they believe is poised for tremendous growth in 2012.
