NEW YORK ( TheStreet) -- High-yield dividend stocks are in focus, as income-oriented investors focus on stable paydays to boost their 401(k) funds. But if you think dividends and high-yield stocks mean settling for boring companies that do little in the way of stock appreciation, think again. You can find exciting stocks even in rather ho-hum sectors many investors think unsexy.

Take utility stocks, which offer high yields and stable revenue streams. These picks may seem safe, sleepy bets, but several utility stocks are breaking out right now and offering big share appreciation alongside hefty dividend payouts.

Here are my favorite 15 dividend stock investments now based on share appreciation.
