Ever been to New York? Wall Street is a meat market, and rightfully so. Investors are looking for the same traits that singles are: Honesty, integrity, a willingness to commit, and smoking hot fundamentals. But to be successful, you've got to know what makes every ticker tick. Use these three pickup lines to help you find the stocks of your dreams.

1. What's a stock like you doing in a place like this?
Sometimes you'll find the hottest stocks in the most boring places. And when you scour those out-of-the-way locales, you're likely to pick up your pretty little undervalued, underfollowed stock on the cheap.

Johnson Controls (NYSE:JCI) may be the only $27 billion company you've never heard of. Founded in Whitewater, Wis., more than 100 years ago, the company heats and cools buildings. Had you started a relationship back in 1990, a $1,000 investment would be worth more than $33,000 dollars today. That's a market-crushing compounded annual growth rate (CAGR) of 26%.

Metrologic Instruments (NASDAQ:MTLG) is a company that appeared on the Motley Fool Hidden Gems Watch List last year. Its line of business: bar code scanners. The stock sank in April 2005 after Metrologic's first-quarter results disappointed many, but this boring company's stock had a meteoric 300% gain in 2003. If the company flies right again, the future remains bright.

2. If I told you that you had a beautiful balance sheet, would you hold it against me?
Sometimes finding great stocks is as easy as looking for cash on the balance sheet. Why? Great companies throw off tons of cash. It's a truism, but that's why truisms are, well, true.

Take Target (NYSE:TGT), for example. Like the other big box retailers, Target is a cash machine. During its high-growth period from 1996 to 2000, Target grew cash flow from operations by 14% a year. Its share price followed suit and then some, surging 35% per year.

But even better than cash flow from operations is a metric known as owner earnings, which at Hidden Gems we calculate as:

net income + depreciation + amortization - capital expenditures

This figure is a good indication of how much cash the company actually banks after regular business maintenance costs, and it can help investors better understand a firm's ability to service and pay down debt. Hidden Gems recommendation Marine Products (NYSE:MPX) nearly tripled its owner earnings from 2002 to 2004. The market rewarded that performance by more than tripling the price of the stock.

3. What's your major?
Every company needs a focus. Some of the greatest stock market success stories are from companies that decided to concentrate operations on high-quality revenues.

Take a glance at Apple's (NASDAQ:AAPL) recent success on the back of the iPod. After hanging around $10 for more than a decade, the stock has been a rocket since early 2004. It currently trades at almost $44, the result of focused promotion of an outstanding product.

For most of its 20-year history, Coldwater Creek (NASDAQ:CWTR) was a catalogue retailer. More recently, the company discovered that it could earn more if it opened stores, so Coldwater has focused on this strategy. The stock has responded, more than doubling in the past year.

Hidden Gems pick Middleby is another example. New management decided to stop selling refrigerators and deli cases and focus on just one product: high-margin ovens for restaurant chains. The move initially led to a decline in sales and earnings, and the stock dropped. But the company soon came to dominate its niche, and the stock's been on a tear ever since. Since 2000, Middleby investors have turned $1,000 into $7,500 -- a CAGR of almost 50%.
