If they aren't questioning the new all-time highs in the market, bears are busy questioning the sustainability of the earnings expansion that has gone on since 2010, explains David Fish in Direct Investing, which specializes in dividend reinvestment plans.

Of course, the two are linked by the fact that earnings growth is what drives prices higher, not to mention encouraging dividend growth.

And strong brand names and popular products are what keep customers coming back for more, leading to earnings growth.

So, while some people seem to have a hard time understanding the prolonged bull market, others are busy accumulating shares of profitable companies, and the easiest (perhaps safest) way to do that is through dollar-cost averaging, something for which DRIPs are ideal.

Our latest featured DRIP recommendation, Dr. Pepper Snapple Group (DPS), was established in 2008, following the spin-off of Cadbury Schweppes Americas Beverages (CSAB) by Cadbury Schweppes plc.

CSAB had formed in 2003 by bringing together four North American beverage businesses: Dr Pepper/Seven Up, Snapple Beverage Group, Mott's LLP, and Bebidas Mexico.

Its leading brands also include A&W, Canada Dry, Diet Rite, RC, Crush, Welch's, Yoo-hoo, Hawaiian Punch, and Sunkist, making it the third-largest beverage company in North America.

The company has increased its dividend for five straight years and now provides a yield of 2.7%. Consensus estimates call for the company to earn about $3.47 per share this year and $3.68 in 2015, compared with $3.20 in 2013.

The company has distribution agreements with both Coca-Cola and PepsiCo, saving it the expense of building its own global distribution network.
