Most of us would be thrilled to invest in a stock that doubles our money, but it certainly isn't easy to find these stocks. According to data provider Capital IQ, in the last year only 1.4% of 6,700 stocks trading on the U.S. exchanges were able to double their price.

BusinessWeek started hunting some of these potentially great stocks by asking fund managers to choose those firms expected to provide 100% returns in the next few years. Of course, the resulting list is by no means a sure thing, since major factors such as the ongoing credit crisis and challenging market conditions could affect results in unpredictable ways.

But let's look at some of the strategies used when picking high-potential stocks.

Mary Lisanti, portfolio manager at the Adams Harkness Small Cap Growth Fund, focuses on young companies in the small-cap segment. She points to stocks like Rubicon Technology (NASDAQ: RBCN) and Titan Machinery Inc. (NASDAQ: TITN), saying that investors can have a big advantage when they recognize potential before the market does.

While researching GPS maker Garmin Ltd (NASDAQ: GRMN) -- whose stock has lost two-thirds of its value in the last six months -- I can't help but pity those long-term shareholders who reject trend following and technical analysis in favor of investing for the long term. To them, it seemed like only yesterday that GPS was one of the hottest technologies around and this industry leader could do no wrong.

Well, that's usually the time to sell, just as I posted on Apple Inc (NASDAQ: AAPL) in January this year and on Google Inc (NASDAQ: GOOG) in November last year, both before they each dropped 40% in just a few months. Because the truth is these popular technology stocks are all expectations. We're not talking Berkshire Hathaway (NYSE: BRK.A)-type value investing here.

Sure, GPS is still hot, somewhat, but due to intense competition, margins have been evaporating, forcing analysts to lower their earnings estimates. In their latest quarter, Garmin further strengthened the bear case with spiking inventories and accounts receivable. None of that looks to change anytime soon, and even though it's got a P/E of 10, book value is all the way down near $11 per share!

The model portfolio of Insiders Plus gains 48% last year; here, editor Jack Adamo reviews two of his portfolio holdings -- both bank stocks being accumulated by Warren Buffett's Berkshire Hathaway.

"U.S. Bancorp (NYSE: USB) reported a slight decrease in Q1 earnings of 62¢ per share versus 63¢ last year; the shares rose 2.8% the next day. Compared to the disastrous results of its peers, this small decline in earnings was a home run.

"That's a testament to the company's savvy managers. USB steered clear of the toxic problems that choked most banks. Only 2.7% of its loans are subprime.

"Warren Buffett's Berkshire-Hathaway continues to buy the stock steadily. Recent SEC filings show that in the fourth quarter of 2007 Berkshire increased its share of the Minneapolis-based bank by 3 million shares to a total of 75 million.

"This represents 4.4% of its shares outstanding, and up tremendously from its stake of 23 million shares just a few years ago. The Wizard of Omaha knows what he likes and why he likes it.

"Meanwhile, Wells Fargo & Company (NYSE: WFC) reported Q1 earnings of 60¢ per share down 9% year-over-year, but up 46% from the December quarter. Like USB, Fargo shares continue to be accumulated at Berkshire Hathaway.

"The stock is a solid long-term buy, with good prospects of steadily raising its 4.2% dividend. It has capital appreciation potential to boot, especially after the housing hangover abates."

This month saw great improvement after last month's disaster. Having to conclude my findings on a specific month end day, or any day, depending on the news, sometimes distorts results. For example news on March 31 sent the market down and on April first my picks shot up an unusual amount; hopefully the trend will continue.

My riskiest stock pick Newcastle Investment Corp (NYSE: NCT) was down the most in March but recovered about 35% of the loss in April leaving Valero Energy Corp. (NYSE: VLO) the dubious honor of being my worst performer, down over 30% in the first four months of the year.

April showed improvement as many companies reported positive earnings reports or beat expectations.

The Dow Jones Industrial Average gained some ground in April as did the Standard & Poor's 500 Index, and the technology heavy NASDAQ Composite Index was up with stocks like Apple, Inc (NASDAQ: AAPL) and Google Inc. (NASDAQ: GOOG) improving significantly on very strong reports. Google is up over 25%.

Most of my picks improved. Higher food prices no doubt helped Bunge Limited (NYSE: BG) which recaptured losses moving up 23% from its recent bottom. My two winners Raytheon Co. (NYSE: RTN), the high tech defense contractor, and Reliance Steel & Aluminum (NYSE: RS) were joined by a third, Anglo American plc (ADR) (NASDAQ: AAUK) which had a 10% swing entering positive territory.

Watching one of your largest holdings go up in value is a vision of joy. The same is not true on the way down. Huaneng Power ADS (NYSE: HNP) is indeed way down from its high of $57.50. I recommended the stock last year at $26.50 and looked brilliant until last month when it completed retracing its upward trajectory back to that level.

The company reported an 80% drop in earnings attributed to higher coal costs Tuesday. However, today the value buyers must be back in droves because the stock closed up almost 16% as one of the day's big movers. The stock closed at $30.25, up over $4 per share. The following three-year chart captures the drama.

Last year I wrote a very positive Chasing Value article suggesting that USG Corp (NYSE: USG) looked like a value proposition when it was trading around $52 a share. We bought it and to say we were way too early would be very very kind because it dropped with the market in the summer and has only recovered slightly.

Even worse, Alan Greenspan and Ben Bernanke are finally talking about a recession and USG is still laying off more workers, attempting to balance labor and product demand in a weak housing market and soft economy.

Berkshire Hathaway (NYSE: BRK.A) is still the largest shareholder, owning over 17% of the outstanding shares. Most of what I liked last year holds true but the depth of the economic downturn shows little signs of improvement. Housing and most related construction service industries are just trying to survive. They have all cut back production.

There is little consensus when the economy might start to show significant signs of improvement, but there are few people who think it will be soon, and I have spoken with many in the business community who think it will be 18 months at least. However, timing the market is always difficult so I believe that the best you can do is try and buy solid companies on the cheap. The difficulties that USG is weathering now will turn into strengths in the future as it streamlines the enterprise, reduces debt, and plans for the future.

After three months it is time to face the facts: two of the three indices beat my picks handily. I have not made a good showing so far and unlike most investment idea sources, I feel obliged to air my dirty laundry for all to see.

My riskiest stock pick Newcastle Investment Corp (NYSE:NCT) is down almost 37% this year, and the energy stocks did almost as poorly even though fuel prices are near all-time highs. The downers were not offset by this months' repeat winners.

March was a seesaw battle, but in the end there was not much to show for it. However, unlike the last day of January (down 370 points in the Dow) and February's last trading day (down 315 points), March had a final day of plus 46.49, which is not very meaningful.

The Dow Jones Industrial Average gave some ground in March as did the Standard & Poor's 500 Index while the technology heavy NASDAQ Composite Index was marginally up with stocks like Apple Inc (NASDAQ:AAPL) improving notably.

Most of my picks sagged a little more, while two remain in positive territory. Raytheon Co. (NYSE: RTN), the high tech defense contractor is up and Reliance Steel & Aluminum (NYSE: RS) is way up.

We recently acquired shares of Tiffany & Co. (NYSE: TIF) at $36.00 ahead of its earnings report. We have been watching it for about 16 months and I thought there was increasing value as the stock started dropping from its 52 week high of $57.34. I had previously brought it to readers' attention in Serious Money: Pondering Home Depot, Tiffany & Wells Fargo. After we put TIF on our watch list, that seemed like all we could do, just watch as it continued to move up farther away from our perceived value. So we just decided to let this train leave the station without us. Then the train came back and rewarded our patience.

Tiffany is a brand name of historic magnitude, pays a dividend, has a business that is easy to understand and is expanding internationally. Yesterday, the stock closed at $43.56 as the company raised its outlook for the year. The stock price is now just above where it was when we started watching it, but long term there might still be value here. I should note that we will not add to our position at this level, but if it drops again we will.

The following ten year chart indicates a highly erratic stock that can swing wildly, as much as $20 in any given year. From 1999 to 2004, there was no appreciation. Interestingly, I would have thought these 20 point swings might be appealing to one of my colleagues who uses charts and is a trader, but it was not. He hated this chart and sees no upward momentum. I on the other hand see plenty to like.

Apple (NASDAQ: AAPL) announced this week it would not use its $20 billion cash hoard for dividend or share buyback in the open market. Some thought this was a good move, some, a mistake. Let me add my voice to those who agree with Apple's management decision.

Apple has been a rocket ship these past three to four years, rising from $12 to over $200 on the strength of popular consumer products. Recently, the company guided to the low end of the Street expectations for the March 31t quarter, and the stock has sold off almost 35%. So, would a share buyback really help? No, I don't think so and here's why.

Like most superbly run companies, Apple is a victim to a slowing economy. There would have been no gain to Apple had it maintained its March quarterly estimates in tact. No gain from being gallant here in this environment. Apple took the occassion to re-set the already raised bar on its expecations. Apple had beaten expectations five of the last six quarters, and analysts were raising the bar habitually. With the share price having suffered in January from the market's selloff, Apple took the opportunity to re-set its own bar.

My stock alert was triggered for Wells Fargo Corp (NYSE: WFC) at $28 per share, two days ago. I did not buy any shares. I would like to own some stock but I'm still hoping for one more dip before I jump in. Having been burned by financial stocks this past year, like many investors, I'm proceeding with caution. It closed yesterday at $28.98.

I suppose I do own some fractional interest indirectly through Berkshire Hathaway (NYSE: BRK.A) and the Vanguard Group Inc., the largest (8.8%) and fourth largest (3%) shareholders in Wells Fargo respectively. By the way, insiders own less than 1% of the company so although "my pal Warren" prefers companies where managers have some skin in the game, this one contradicts that philosophy. The respected Chairman CEO, Richard M. Kovacevich, has actually been the largest seller of the stock, which he does through a planned process almost every two months.

Wells 52-week high / low range is $37.00 / $24.38. Although I did not buy any shares yet, I do get the feeling that Wells Fargo may look like a steal in 12 months. It is the fifth-largest bank in the United States. Regular readers of the column know I missed another stock Anglo American.

Perhaps it was childish not buying WFC on Tuesday, but financial stocks and commodities are two very different things right now...

Two months into the year and investors' true 'metal' was tested, and mine more than most. February showed signs of improvement over January, but the last week ended hopes of any rally. The last day of January saw a 370 point drop in the Dow and February's last trading day closed with similar results, down 315 points.

The soft stock market did display many points worth noting. The Dow Jones Industrial Average was about break even for the month, indicating investors were showing some signs of support for large cap stocks, prompted in part by news of increased profits at Wal-Mart (NYSE: WMT) and share buy-backs at IBM Corp (NYSE: IBM).

I cannot say the same for the other major indices, NASDAQ Composite Index and Standard & Poor's 500 Index, which dropped significantly last month.

Some of my picks also sagged a little more, although not as much, while two turned into positive territory. In January, only Raytheon Co. (NYSE: RTN), the high tech, defense contractor, was up. In February, the weak dollar and inflation concerns boosted Anglo American plc (ADR) and Reliance Steel & Aluminum (NYSE: RS) -- two commodity plays.

The latest issue of Barron's is suggesting that investors may want to look at beaten down, debt-laden companies(subscription required):

Blackstone Group, Apollo Management and the rest of the private-equity crowd may be sidelined by the mess in the credit markets, but investors still can play at their game by purchasing shares of debt-laden companies in the public markets.

Barron's goes on to suggest that, if credit markets stabilize, some companies with heavy debt loads will rebound well. I don't dispute this analysis but I also don't think most investors should go chasing companies with big debt loads. It's always struck me as being somewhat akin to tiptoeing in front of steamrollers to pick up a penny. I've never bought shares of a company with a lot of debt. Sophisticated investors with an ability to really understand the debt, how it's structured, and the risks that go with it may do well with these companies. But if that isn't you, I think your best bet is to stay away.

As Barron's warns, the ultimate danger with investing in heavily leveraged companies is bankruptcy. If you're a disciple of Warren Buffett's first and second rules of investing -- don't lose money and don't forget rule number 1 -- this probably isn't a game you want to be playing.

Many readers have been intrigued by my recent posts (Will Chase (JPM) or Wells Fargo (WFC) buy WaMu (WM)? and Wells chasing Chase for WaMu -- Act II) regarding various strategic scenarios that might make sense for either J. P. Morgan Chase & Co. (NYSE: JPM) or Wells Fargo & Company (NYSE: WFC) to acquire Washington Mutual, Inc. (NYSE: WM).

If something is happening along these lines, it is all happening quietly behind closed doors. More than one reader suggested that no deal is possible because the Washington Mutual CEO, Kerry Kilinger, does not want to give up his throne and has too high an opinion of himself and the value of the company.

From my perspective this is a deal that has to get done, and if the CEO stands in the way of shareholder, employee, and customer interests he has to go. Time to bring in the corporate raiders -- you listening Carl Icahn; can a deal be done Norman Peltz? Hey Eddie, maybe you could make back the money you lost on Citigroup (NYE: C)! If there were ever a great opportunity this seems like it. The raiders do serve a market purpose.

There are potential buyers waiting in the wings so the raiders could move in friendly like, or do it the hard way, buying in at depressed stock prices, forcing Killinger into submission and doing a quick flip. I think even 'my pal Warren' of Berkshire Hathaway (NYSE: BRK.A), a major investor in Wells Fargo, must be doing some heavy duty pondering on the subject.

I'm sure the downtrodden stock market has brought sadness to many people. As someone looking long term I am trying to put the current market into perspective. 'My pal Warren' always says that truly astute investors should actually be happy when the market is down because they are able to buy things on sale. I agree, so what to buy?

Three of the stocks I have been following fall into very different arenas. One is being severely affected by the housing market and familiar to the average consumer. The second might be a familiar name but not a daily haunt by the average consumer. The third falls into the middle ground and is a solid company and favored by Warren Buffett who owns shares through Berkshire Hathaway (NYSE: BRK.A).

It's been a while since I wrote about The Home Depot, Inc. (NYSE: HD). My optimism last year about the company proved misguided as the stock tread water most of the year and then took a dive as earnings reports deteriorated. When I originally commented on HD 14 months ago it was trading at $39.73, finishing the year at $26.27 for a loss of 33.88%. It started with a 2.31% yield .

We now own Newcastle Investment Corp. (NYSE: NCT), a CMBS lender and REIT paying about a 26% yield in several portfolios. It does not own real estate, instead it holds loans on nonresidential properties.

NCT is on record to fully fund its dividend and anticipates one billion dollars in loans to be paid off in the coming year. It is one of my 8 for 2008. See original full story: Chasing Value: Newcastle's 22% yield will reward patience.

The stock has lost two thirds of its value from its 52-week high and closed at $11.08 yesterday down further from my initial buy-in. The stock is down because of investors fears about the real estate values supporting the loans and the resemblance to residential mortgage brokers and lenders that have collapsed or suffered great losses. Neither of these issues are of concern to me. I am active in the commercial real estate markets and we have not seen appreciable reductions in the value of existing commercial and industrial property.
