The price-to-cash flow ratio has been repeatedly promoted in various publications as one of the more important metrics to consider when evaluating a stock to buy. Apparently over long periods of time it is more telling than the often quoted price-to-earnings ratio. I have read that cash flow is a key metric that "my pal Warren" looks at for Berkshire Hathaway (NYSE: BRK.B) investments.

Here are the figures for the Chasing Value: Final list -- 8 stocks for 2008 in order from highest to lowest P/CF. The 12/28/08 starting stock price, yesterday's closing price and the current P/CF for the most recent fiscal year (MRFY) are listed. Only two stocks are up, while six are down.

Reliance Steel & Aluminum (NYSE: RS) made my 2008 short list. It processes and distributes more than 100,000 products made of carbon, alloy, stainless, and specialty steel, as well as aluminum, brass, copper, and titanium. It serves more than 125,000 customers. On December 28, 2007 RS closed at $54.32 per share.

Commodities have been hot the last few years and there has been a lot of activity as the steel market in particular has seen a lot of mergers. The downturn in construction in the latter half of 2007 has affected the stock prices of most companies producing building materials, and most of the steel mills would be included in that category.

Reliance seems to have escaped that pitfall by making value-added products for a very broad range of industries and customers. This specialization is why I picked it over one of my other contenders Nucor Corporation (NYSE: NUE), which is one of the world leaders in the idea of mini-mills. Nucor is a wonderful company that has been very successful; however, in a sputtering economy you have to be able to distinguish yourself from the crowd.

Year-end is almost upon us and I need to get this short list cut down to size with two weeks to go. Because this story is an ongoing process, the heart of the story, the possible stocks, are posted below again, with the latest in bold type as the story builds and I examine things more closely. This week I am adding another energy play in the form of a Canadian Trust. Then I follow with the current edited stock list and the stocks to be cut.

In seeking value stocks that have seen their share prices greatly diminished this past year based on reduced earnings, I came across Precision Drilling Trust ADR (NYSE: PDS), which has a P/E near 5 and a dividend yield over 10%. According to AOL Money & Finance information, the company is Canada's largest drilling contractor, with a fleet of 240 service rigs. Its contract drilling units provide drilling services, equipment supply and repair, and on-site catering and management. PDS has extended its reach into the United States this year and has invested in new technology, replaced older rigs and is preparing for continued expansion. Favorable metrics include a low P/B of 1.57 and high historic profit margins of 40%.

PDS closed yesterday at a price of $15.47 per share, near its 52-week low of $15.35, a low set today during the trading day, and 44% off its high of $27.78. The P/E is a trailing figure and is actually higher but the dividend looks secure. For a few more details see: Chasing Value: Precision Drilling for 10% yield.

Disclosure: I have already bought shares of PDS at $17 in several portfolios.

The following stocks have been put in three groups, considering I want to reduce the number to eight. The first group is highly likely to make the cut based on what I know today. The second group is still under consideration but depends on what the value is in two weeks because of current volatility. The last group is being cut, and I noted why.
