You should always focus on generating steady cash flow through dividends for your portfolio. Minimize risk, even if it seems boring. That’s why I like Black Hills Corp. (NYSE: BKH). The 4.8% dividend yield and 13% gain year-to-date should be enough to entice anyone — but top that off with a history of dividends since 1942, and you have an income investment that’s a lock.BKH may not be very sexy as a utility operator with a market cap of around $1 billion. But leave the sexy semiconductor and biotech trades to aggressive, high-risk traders and bank on some steady appreciation and a big dividend from this great utility stock.
