It's been a strong year for Banco de Chile ( BCH), another foreign banking stock that's boasting a hefty short interest ratio right now. Shares have rallied more than 13.7% in the last 12 months, returns that look even more impressive when they're compared to the 21.6% decline that the financial sector has posted over that same period. The Latin American banking sector has been heating up for the past several years, and BCH has been a big beneficiary. The firm dramatically increased its top and bottom lines during the recession, an impressive feat given the fact that the financial crisis had a worldwide reach. Comparatively higher rates in the Chilean market mean that BCH is able to collect some impressive margins on its banking business -- more than 31% in the firm's latest quarter. Again, here's a case where a high dividend and currency exposure are fuelling shorts. The firm's 3.79% payout is based on earnings in Chilean pesos, another currency with a checkered past that looks less attractive given the dollar's recent strength. That said, Chile boasts a very different banking industry than ours here at home, and many investors are welcoming the peso exposure. The firm's short ratio of 11.2 makes it a solid short candidate for 2012.
