Is it possible to determine the top-performing stocks of the next half-century? Before looking into the future, we need to consider the past. So let's start at the very beginning, as Julie Andrews might say.

Fishing in a well-stocked pond
Those familiar with the work of Wharton professor Jeremy Siegel will know that dividend-paying stocks such as Altria and Coca-Cola have been some of the stock market's best performers since the beginning of the S&P 500 back in 1957.

The key to the amazing returns of these stocks was reinvested dividends. This is a theme we've covered in many articles here at the Fool, but that insight is worth emphasizing. If we are searching for top stocks for a time frame of 50 years, we need to look at dividend-paying stocks.

One place to begin our search might be the Mergent Dividend Achievers Select Index, whose constituents are U.S.-listed companies that have all increased their annual dividend payments for 10 or more consecutive years. Since 1997, the index has returned 9% per year on average, which compares very favorably with the S&P 500's 6% over that time.

The magnificent seven
The index contains 215 dividend-paying companies. I've put together a sample of seven of them below:


Dividend Yield

Allstate (NYSE:ALL)


Ambac Financial (NYSE:ABK)


Clorox (NYSE:CLX)


T. Rowe Price (NASDAQ:TROW)


Nordstrom (NYSE:JWN)


Ecolab (NYSE:ECL)


Holly Corp. (NYSE:HOC)


Data from Yahoo! Finance as of Dec. 28, 2007.

Most of these companies need no introduction. After all, who hasn't heard of Allstate, Nordstrom, or T. Rowe Price? However, some of these names may be new to you.

Ambac has been in the news a lot lately -- and not for good reasons. Fitch has ordered this bond insurer to raise $1 billion in additional capital by the end of January, or Ambac will lose its coveted "AAA" rating. This helps explain why the stock has slid from a high of $96 to today's price around $24 -- a 10-year low. But the bond insurance industry can be very lucrative, and a lot of smart investors -- including one Warren Buffett -- have begun taking notice recently.

You've probably never considered investing in companies that specialize in toilet bowl cleaners and "pest elimination services," but Clorox and Ecolab have both been long-term market beaters. And talk about a stable business -- Ecolab has paid a dividend since 1936, and has boosted its annual payout for 16 straight years.

Last, but certainly not least is Holly Corp, which has been a nine-bagger over the last five years. Despite that impressive surge, this petroleum refiner believes that shares may still be undervalued -- it recently boosted its stock repurchase program by $200 million.

Will any of these be among the top stocks of the next 50 years? It's tough to say for sure, though I do believe one or two will make the list.

Looking ahead
So, to recap: If history is any indication, the top stocks of the next 50 years will be businesses that have stable, growing dividends; reasonable valuations (part of the reason for Altria's outperformance, Siegel says, is that the constant threat of litigation meant it was always undervalued); and good managers.

Even if you find a top stock of the next 50 years, the only way you'll benefit from those potential gains is to hold for the long term and let the power of reinvested dividends work in your favor.
