Now more than ever, a comfortable retirement depends on secure, stable investments. Unfortunately, the right stocks for retirement won't just fall into your lap. In this series, I look at 10 measures to show what makes a great retirement-oriented stock.

Coca-Cola (NYSE: KO) is the best-known brand in the world, and with Interbrand estimating its brand value at a whopping $72 billion, the company milks every penny it can from it. With its global presence, it's hard to believe that the maker of such a simple product could have achieved such success. But investors can't afford to look backward at a company's success, and some question whether Coke has the growth left in it to keep being a good value for shareholders. Below, we'll revisit how Coca-Cola does on our 10-point scale.

The right stocks for retirees
With decades to go before you need to tap your investments, you can take greater risks, weighing the chance of big losses against the potential for mind-blowing returns. But as retirement approaches, you no longer have the luxury of waiting out a downturn.

Sure, you still want good returns, but you also need to manage your risk and protect yourself against bear markets, which can maul your finances at the worst possible time. The right stocks combine both of these elements in a single investment.

When scrutinizing a stock, retirees should look for:

  • Size. Most retirees would rather not take a flyer on unproven businesses. Bigger companies may lack their smaller counterparts' growth potential, but they do offer greater security.
  • Consistency. While many investors look for fast-growing companies, conservative investors want to see steady, consistent gains in revenue, free cash flow, and other key metrics. Slow growth won't make headlines, but it will help prevent the kind of ugly surprises that suddenly torpedo a stock's share price.
  • Stock stability. Conservative retirement investors prefer investments that move less dramatically than typical stocks, and they particularly want to avoid big losses. These investments will give up some gains during bull markets, but they won't fall as far or as fast during bear markets. Beta measures volatility, but we also want a track record of solid performance as well.
  • Valuation. No one can afford to pay too much for a stock, even if its prospects are good. Using normalized earnings multiples helps smooth out one-time effects, giving you a longer-term context.
  • Dividends. Most of all, retirees look for stocks that can provide income through dividends. Retirees want healthy payouts now and consistent dividend growth over time -- as long as it doesn't jeopardize the company's financial health.

With those factors in mind, let's take a closer look at Coca-Cola.

Since we looked at Coca-Cola last year, the company has kept its seven-point score. The drink giant doesn't quite squeak under our valuation guidelines, but it has a lot of what conservative investors like to see in a stock.

Coca-Cola has come a long way from its humble beginnings. After getting booted out of the Dow Industrials in 1935, it took Coke more than 50 years to earn its way back in. But along the way, it became an iconic product in American culture and took the world by storm. It's easy to conclude that Coke's fastest growth days are long behind it.

But Coke definitely hasn't stopped growing. A few years ago, the company bought the North American bottling operations of Coca-Cola Enterprises (NYSE: CCE), making itself more vertically integrated, and paid Dr Pepper Snapple (NYSE: DPS) $715 million for the rights to distribute some of Dr Pepper's brands. And in its most recent quarter, the company posted 10% earnings growth after adjusting for extraordinary items. The Chinese emerging market was a big growth driver, with volumes up 13% there. Coke is looking to cut as much as $650 million in costs by 2015. And importantly, the company stood up to Monster Beverage (Nasdaq: MNST) and Red Bull with strong growth in its energy-drink segment, showing its ability to expand beyond its core offerings.

Still, Coke doesn't get a free ride. PepsiCo (NYSE: PEP) continues to be a solid threat, as its diversified drink and snack business gives it somewhat more room to be innovative. Moreover, both companies have warned that high sugar prices could slow their profit growth -- although sugar has come off its highs in recent months.

For retirees and other conservative investors, a solid dividend that's likely to hit its golden anniversary by celebrating 50 years of consecutive annual dividend increases this year is the key driver for the stock. Combine this with prospects for further emerging-market growth, and Coke deserves a place in many retirement portfolios, even at its mildly expensive valuation.
