Learn the five mini-bull markets that will stampede for years, starting with aerospace and defense, agriculture, oil and oil service, minerals and mining and infrastructure.

Agriculture

Energy independence is a goal of both American political parties. The farm states have tremendous political power. That combination has produced one of the most amazing booms that our nation has ever seen: the agricultural boom, which is still in its infancy.

TST Recommends

You may not be filling up with ethanol yet -- you may not even believe in renewable resources -- but the commitment's been made, and being a farmer in this country is going to be lucrative for years to come. Throw in the fact that the federal government has proven to be completely incapable of reining in farm subsidies and you can see why "farm" replaces "pharma" in this generation's raging bull markets.

Most people on Wall Street are skeptical of this group. They view it as a boom-bust sector, a cyclical sector with good times and bad. They fail to realize that the commitment to domestic fuels that don't destroy the environment (hence no coal) is irreversible and growing.

I like to look at the stocks in the ag bull market as secular growers, immune to the economy's vicissitudes. They should be viewed not as companies that help bring food to market but as companies that are the new oil-service companies, suppliers of energy at less and less cost each year, as the companies improve their products.

The ag bull market is a tight-knit one. There's

Deere

(DE) - Get Report

for farm implements,

Monsanto

(MON)

and

Bunge

(BG) - Get Report

for seeds -- each is amazing at producing strains of vegetables that can generate more and more fuel per stalk of corn or soy -- and

Agrium

(AGU)

and

Mosaic

(MOS) - Get Report

for fertilizer.

It's not a big cohort, but it is one that has become a market leader and has proven to go up no matter how the stock market performs. Deere is the best in show of this group, but Monsanto's the sleeper. The market values it as if it were a stodgy old chemical company, its legacy. In reality, it is a company that produces patents to develop better and better seeds. I consider it a biotech company for fuel, and that's something that will be in demand for years and years to come.
