It's a good time to be a little defensive in the stock market, to look at stocks with a history of increasing earnings as well as dividends. While these don't tend to have a catalyst that will vault them into the stratosphere the way a tech or biotech stock can, they give a lot of comfort when there's so much turmoil in the market.

The first thing to think about when you're on defense is the shape of the economy and the kinds of items consumers always buy, no matter what the economy is doing. Consumer spending makes up about 2/3 of the U.S. economy. What the consumer does matters. Right now many consumers are having trouble paying their mortgages. Housing prices are going down in many areas of the country. Large mortgage lenders such as Countrywide Financial Corp. (NYSE: CFC) and IndyMac Bancorp. (NYSE: IMB) k are having problems with their portfolios. Defensive investors won't be looking into the mortgage lending stocks for comfort.

More likely they'll be looking at companies that supply things that people must buy, things like drugs, toothpaste, gasoline, toilet paper (also known as bathroom stationery), soap, food, utilities, etc. These are the basics. They're supplied by many different companies, and many of those companies are improving, even in these difficult times. Here are just a few ideas (not recommendations for investing, but recommendations for more investigating):
