4. MEMC Electronic Materials (WFR) makes polysilicon and wafers for the solar energy and semiconductor industries.
3. TCF Financial (TCB) is a Midwest bank with retail and wholesale banking businesses. Barclays notes that its seven-day branch operations and outstanding deposit base afford it a "best-in-class net interest margin." It has a strong leasing and equipment finance lease division, which will grow lending in 2011. Regulatory hurdles, including lower service fees stemming from the Dodd-Frank Act, present a potential headwind, which could damage its debit card fees anywhere from 20% to 80%. Still, TCF is an exceptionally well-run bank, with 62 quarters of consecutive profitability and higher-than-average capital ratios. Barclays projects a $22 share price, suggesting 51% of upside in 12 months.
