Warren Buffett Is a Growth Investor

Don't tell Gerald Martin and John Puthenpurackal of American
University and UNLV. In 2008, the two completed a paper that analyzed
both Buffett's superior investment performance and his investing style.
Besides concluding that Buffett's superior investment returns
since 1976 were more than just luck -- big surprise! -- Martin and
Puthenpurackal argued that Warren Buffett is... wait for it... a
large-cap growth investor.

According to the researchers' definition of "growth," stocks with
the highest book value-to-market-value ratios are value stocks, while
those with the lowest such ratios are growth stocks. The paper
concludes that growth stocks accounted for more than 40% of Berkshire's
investments, while true value picks made up less than 20% of Buffett's
buys.

Buffett is still very much a value investor by his own definition:
He only buys stocks at a discount to their companies' intrinsic value.
But if we're looking for Buffett-esque stocks, this study does suggest
that we pursue high-quality companies, rather than rummaging through the dregs of the bargain bin.

To track down some stocks that might fit the bill, I've enlisted the help of our Motley Fool CAPS stock screener. I focused my search on stocks that are returning 10% or more on their equity, trading above book value, and highly rated by the CAPS community. (You can run the same screen, though its results may differ as the market changes.)

While these aren't meant to be formal recommendations, they're a
great place to kick off some more research. Why don't we start with a
closer look at Dynamic Materials?

The anatomy of a growth stock

When corrosive production environments collide with the need for cost savings, Motley Fool Hidden Gems pick Dynamic Materials may be the solution.

Companies like Dow Chemical (NYSE: DOW) and Valero (NYSE: VLO)
create and process chemicals at high temperatures and pressures.
Unfortunately, these conditions will eat up normal metals like John
Madden on a Thanksgiving turkey. One solution is to build processing
components entirely of durable metals like titanium or zirconium -- but
that's expensive, not to mention overkill in most instances.

Dynamic Materials produces "explosion-welded clad metal plate." As
the name (and the company's ticker symbol) suggests, Dynamic uses
explosives to blast together a corrosive-resistant metal with a cheaper
base metal. This creates a corrosion-resistant surface without the
expense of equipment built entirely of that metal.

Dynamic Materials has been wildly successful -- sales grew more than
500% between 2003 and 2008 -- for a number of reasons. First off, the
need for clad metals has been growing, particularly within the oil and
gas industry. At the same time, Dynamic's explosion welding has
significant advantages over other methods of cladding, and the company
has developed expertise in large-scale production of explosion-welded
metals.

CAPS or bust

Today's economic realities
have weighed on Dynamic Materials' business. First-quarter sales and
earnings both fell, as the company's backlog continued to slide
downward. Members of the CAPS community, however, are looking past
current results to examine the company's long-term potential.

Top-performing CAPS member tenmiles became a Dynamic Materials bull earlier this year, pitching:
"Just a deep value play at $13.60; end markets are obviously weak, but
niche player seems to discount most of the troubles at current
valuation for investors with at least 3 year horizon."

More recently, CAPS All-Star kevinottofro also gave the stock a thumbs-up, calling out
the stock's low valuation ratios and its five-star CAPS rating. While I
don't see a near-term turnaround for the external pressures that
Dynamic is facing, I happen to agree with both of these high-ranking
CAPS members and have rated the stock an outperformer in my CAPS portfolio.

But here's the real question: What do you think of Dynamic Materials' prospects? Let the CAPS community know sharing your opinion with the 130,000 investors already participating.
