I spent some time over the weekend scanning through the Fortune 100 Fastest Growing Companies for 2007 for companies that interest me. I would look at the company’s business, recent sales and earnings, and future earnings projections. No calculator, just an eyeball on growth rates vs. PE. It was interesting, since the list was compiled in mid 2007, how many companies on the list had had recent earnings set backs. While going through the list I noted some personal likes and dislikes of company attributes that cause me to look favorably or unfavorably on a stock.

Some of my dislikes:

* Companies that have business selling to other companies. There is something about a company that is reliant on another company or industry to manufacture good products and sell them profitability that I avoid. Even if the company is the best around and well run, bad economics or management by their customers can seriously affect the suppliers bottom line.

* Faddish retail companies. Clothing lines, beverages and restaurants. These can all lose ground to the next hot item if they do not come up with the next hot item themselves.

* I have a tendency to avoid all health care and pharmaceuticals. Although health care sucks up a huge portion of the U.S. GDP, I just feel the whole thing is propped up by ever increasing costs that will someday collapse. I am probably entirely paranoid here, but I do not invest in this area.

* Fast growing companies with no earnings set off warning bells in my head. It is my belief that it is easier for a company with hot products or in a hot sector to grow revenues than earnings. A hot company has to start bringing significant dollars to the bottom line before I get interested.Some of my preferences:

* I gravitate to companies with market capitalization between $500 million and $2 billion, plus or minus. I believe companies this size are big enough to have established themselves, but too small for most of Wall Street to have found. Often they have between 1 and 4 analysts following them and good information is hard to find. Maybe I can find a nugget of news that shows me the market has miss-valued the stock.

* I like industries with products people and business must have: Energy, transport, gambling, banking., infrastructure. Well run companies in these business can often count on a certain built in customer base and work to maintain or improve margins.

* I get interested in a company that has a business or niche I have not previously heard of. This might be a company that has carved out a profitable niche by offering a unique product or service.

I will read deeper to see if there is more to get interested in.Once I find a company of interest I usually add it to my Watch List. At some point I will come back to it and dig deeper into finances and their story. It may be the next day or weeks down the road. Right now energy companies are hot and anything to do with home construction is not. I have some of both on the Watch List to get back to as market conditions change. When I review deeper I may keep a stock on the list, remove it because I do not find a compelling reason to keep monitoring it, or move it to one of the portfolios I track here. One thing I try to keep in mind is that prospects change for companies, sectors and markets and it is important to keep options open.by Tim Plaehn, published at www.gracecheng.com
