When asked for the secret of his success, baseball player Wee Willie Keeler replied, "Hit 'em where they ain't." What worked for Willie at the plate applies equally well in investing. 

Seeking stocks that others ignore, shun, or simply forget gives individual investors like you an edge over the professionals. When Wall Street turns a blind eye, you have a chance to get in before these stocks get discovered -- or rediscovered -- and start taking off. 

Below, we'll check out companies with only a handful of analyst coverage, then pair our list with the opinions of the Motley Fool CAPS community. A stock that garners CAPS' top ratings, but hasn't yet caught analysts' attention, could be your next home run investment.

As biodiesel maker Syntroleum's stock has fallen (down by a third year to date), insiders have been picking up blocks of shares on the market. One director in particular has purchased nearly 150,000 shares at prices ranging from $1.60 to $2.00 a share, no doubt expressing confidence in its joint venture with Tyson Foods. While there's some concern about the failure of Congress to reenact a $1.00 per-gallon tax credit for renewable diesel and biodiesel fuels, CAPS member DCMonty25 that government initiatives will ultimately drive the stock higher.

… Government interest. Obama called for greater focus on renewable fuels and "green" technologies, and Syntroleum's process converts animal fats and greases to high-quality diesel and jet fuel. Additionally, the military has shown interest in Syntroleum's jet fuel, given its high-grade and quality. Aside from the fuels, the Dept. of Energy recently awarded Syntroleum a demonstration contract for "phase change" materials, which are used to regulate the temperature of buildings. These materials will also be produced at the Geismar facility, and, if successful, offer a very attractive return.

All charged up
The move toward electric motors in cars has generated a lot of enthusiasm in the auto industry. It's reminiscent of the period in the early part of the last century when there were dozens of carmakers vying for attention.

While Tesla has captured the imagination of many investors, there are several private carmakers including Fisker and Code hoping to gain some market and mind share, and foreign carmakers including Berkshire Hathaway's (NYSE: BRK-A) BYD in China are trying to gain traction as well. Both Nissan (Nasdaq: NSANY) and General Motors expect their own electric cars to hit the market.

Yet CAPS members remain skeptical, with two-thirds of those rating Tesla expecting it to underperform the market. That could be because while the Leaf, Volt, and Coda are all relatively affordable (once you factor in government subsidies), the Tesla remains an expensive luxury car, which A6EIntruder feels will appeal only to the glitterati

the green car revolution cannot ride on the spaceframe of a two-seater that costs more than $80k. It also will not ride on a four-person car that costs $40k.

The Japanese Import Revolution was borne on fuel-efficient and practical cars like the Toyota Tercel and the Honda CVCC. They didn't cost a mint and lasted. Tesla doesn't fit this bill in any way, shape, or form. 

A utility player
While there's lots of skepticism also built into Zion Oil & Gas because of a biblical belief there is oil in Israel, CAPS member 78TAX offers a more practical assumption: "I think they will hit it big. Oil all around them all four sides."

When you think about it like that, it doesn't seem to require such a willing suspension of disbelief that they will be successful. And there have been brief periods of discovery though they've never amounted to much. Total (NYSE: TOT) found oil north of the Sinai Peninsula in the 1980s but the wells subsequently went dry, and Isramco found oil off the coast of Tel Aviv, but never enough to make it profitable. And Noble (NYSE: NE) has found a large gas deposit in the Tamar region.

Interestingly, CAPS members think Zion has a better chance of finding oil in the Middle East than Tesla has of making it as a mainstream car company.
