Carl Icahn, the famous activist investor, resigned from the Yahoo! (NASDAQ: YHOO) board of directors Friday.

This comes just over a year after he scored the position, following the seemingly endless talks the company had with Microsoft (NASDAQ: MSFT) over the possibility of a takeover. Icahn told Yahoo that he was resigning effective immediately because Yahoo! didn't need an activist investor on the board at this time.

Yahoo! (NASDAQ: YHOO), a web portal whose colleagues include Google (NASDAQ: GOOG) and Time Warner's (NYSE: TWX) AOL, reported Q1 numbers after the bell on Tuesday. According to an earnings preview done by colleague Mark Fightmaster, Wall Street was counting on something along the lines of 8 cents per share. Well, on a non-GAAP basis, Yahoo! earned 15 cents per share. Not bad.

Unfortunately, Yahoo! made three pennies more on the same adjusted basis in last year's similar quarter. Furthermore, revenues, adjusted for currency effects, dropped 8%. Oh, and one more thing. Free cash flow decreased over 60%.

With only a day of trading remaining in February, stocks are poised to post another monthly loss. There have been very few stocks going higher in this very persistent bear market.

One exception to the rule has been Yahoo (NASDAQ: YHOO). Can you believe it?

Get rid of that nitwit Jerry Yang, and this stock is finally catching some tailwind.

Shares have gained more than $1 in value in February, as investors unwound short positions tied to the ineptitude of Chief Yahoo. In addition to short covering, shares caught a bid as buyers look to acquire shares at a discount in case a new deal for the company emerges.

Yahoo! (NASDAQ: YHOO), which competes with Google (NASDAQ: GOOG), Microsoft (NASDAQ: MSFT), and Time Warner's (NYSE: TWX) AOL, reported Q4 stats after the bell on Tuesday. They were pretty dismal, but expectations were bea t. Revenues dipped by 1%, and earnings per share on an adjusted basis were $0.17. According to Wall Street's view, Yahoo! was only supposed to earn $0.13. A four-penny beat on the bottom line is a pretty good thing.

Or is it in this case? I would argue it's no big deal. I mean, we are talking about Yahoo! here, and there's a new CEO on the job, Carol Bartz. She replaced the disaster known as Jerry Yang. Considering that there's a new regime, you can't really rely on this beat as a proper indicator for what's to come.

Yahoo! Inc. (NASDAQ: YHOO) is scheduled to discuss fourth-quarter and full-year 2008 results today in a conference call at 5:00 PM Eastern. You can catch the live webcast of the call on the company's website.

For the quarter that saw the departure of CEO Jerry Yang and on-again off-again negotiations with Microsoft Corp. (NASDAQ: MSFT), analysts polled by Thomson Reuters expect Yahoo! to report a profit of $0.13 per share, compared to $0.15 per share in the same period of the previous year. Revenue for the quarter is expected to total $1.4 billion, down 2.3% from a year ago. Yahoo! earnings have topped estimates in four of the past five quarters.

Yahoo! They found someone for the gig. Former Autodesk (NASDAQ: ADSK) CEO Carol Bartz has reportedly accepted the top job at Yahoo! (NASDAQ: YHOO), according to the Wall Street Journal (subscription required.)

Industry watchers have considered Bartz a leading contender for the CEO spot left vacated by co-founder Jerry Yang for a while now. But filling the job proved contentious... and difficult. Seems nobody wanted the task of trying to turn around the troubled company's fortunes. While it enjoys rich content and traffic, this early internet player has also been beset by internal and external troubles for years. Much of its executive and technical talent has left for greener pastures.

Bartz, 60, is a well-regarded tech executive. She presided over Autodesk from 1992 through 2006, during which the company saw robust growth. She served as Chairman, president and CEO of the company, and remains on as its executive chairman.

Bartz has had stints at many tech firms over the course of her career. She was an executive at Sun Microsystems Inc., (NASDAQ: JAVA), Digital Equipment Corp., and 3M (NYSE: MMM). She also sits on a number of boards, including the board of Cisco Systems Inc. (NASDAQ: CSCO), with predecessor Jerry Yang.

There's no doubt about it -- times are tough. People are struggling to find work and to pay the bills as the value of their homes and savings dwindle. The poor get poorer, and the rich get richer.

Or do they? It's all relative, of course, but world's billionaires have been taking some big hits too. We take a look at Sheldon Adelson, Kirk Kerkorian, and Lakshmi Mittal in their own separate posts, but here are some other billionaires who have lost billions this year (courtesy of Forbes and Business Sheet).

• Brothers Anil and Mukesh Ambani of India's private conglomerate Reliance lost $32.5 billion and $28.2 billion, respectively.
• Warren Buffett, the Sage of Omaha, lost $16.5 billion. Shares of Berkshire Hathaway Inc. (NYSE: BRK.A) are down about 32% since the beginning of the year.
• Microsoft (NYSE: MSFT) founders Bill Gates and Paul Allen lost $12.3 billion and $2.6 billion, respectively, while CEO Steve Balmer lost $6.5 billion. Shares of Microsoft are down 46% since the beginning of the year.
• Larry Page and Sergey Brin, cofounders of Google Inc. (NYSE: GOOG), lost $11.9 billion and $11.7 billion, respectively, and CEO Eric Schmidt lost $3.8 billion. The share price of Google has fallen 55% since the beginning of the year.
• Larry Ellison, CEO of Oracle Corp. (NASDAQ: ORCL), lost $8.2 billion. Shares of Oracle are down 21% since the beginning of the year.
• Media maven Sumner Redstone lost $7.2 billion. Shares of his private investment firm National Amusements fell 70% this year.

In 2008, many big names took big face plants. Since this is a blog about money, I ranked them based on how much they lost and how far they fell. As you can see, the method is not exactly scientific. Here are the five biggest falls from grace:

1. Richard Fuld, Lehman Brothers. The $639 billion bankruptcy is history's largest so far by a factor of at least six. And Fuld personally lost about $1 billion in his personal holdings of Lehman stock. And the repercussions of letting Lehman fail stretched from money market funds to Iceland. Ouch!
2. Jimmy Cayne, Bear Stearns CEO. Cayne lost plenty of his personal wealth when Bear Stearns stock stumbled. But at least shareholders were able to get out with something when JPMorgan Chase (NYSE: JPM) bought it.
3. Eliot Spitzer, New York governor. Spitzer destroyed his once promising political career by spending time with at least one woman other than his wife. He was trying to use his prosecution of Wall Street to boost his political career as Rudy Giuliani did. But his self-destructive urges got the better of him.
4. Sheldon Adelson, CEO, Las Vegas Sands (NYSE: LVS). Adelson, a colorful character who was a consulting client of mine, has lost $30 billion on paper thanks to his excessive debt load and a decline in gambling.
5. Jerry Yang, CEO, Yahoo! (NASDAQ: YHOO). Poor Jerry Yang suffered from delusions about his ability to revive his creation. He lost a chance to boost shareholder returns by selling to Microsoft Corp. (NASDAQ: MSFT) for $31 a share. With the stock at $11.51, he left big bucks on the table, and the board kicked him out of the big chair.

Let us know which one you would chose as the biggest fall of 2008.

In the decades to come, business school students will be faced with a plethora of examples from 2008 in studying how not to do something.

Picking one business decision as the worst is sort of like choosing a favorite child. Each was wretchedly awful in their own unique way. They each deserve their own wing in the hall of shame, but there only can be one winner. In my mind, the company that consistently shot itself in the foot with a heretofore unknown precision was American International Group Inc. (NYSE: AIG).

Of course, AIG is now owned by the U.S. government, largely thanks to two bailouts. The government ripped up the first $85 billion deal after determining that the New York-based company needed an even bigger life preserver of $150 billion. Even then, it managed to post a $24.5 billion loss.

What set the standard for corporate hubris, though, were the junkets. There was a fun-in-the-sun getaway to a resort in California, only days after the $85 billion bailout went through. Recently, it was disclosed that another junket was held in Arizona. Though the amount of money involved in the gatherings was piddly, the principle at stake was not. AIG was telling people -- especially members of Congress who approved the bailout -- that nothing had changed when, of course, everything had.

Lately it's been very difficult for investors to get their bearings, but I can tell you that the winners in this game will be companies with little or no debt. Forget what stock values are doing now and focus on the future. You can take it to the bank that stocks gaining in value will have started from a very solid balance sheet foundation.

That said, I want to talk about Yahoo (NASDAQ: YHOO).

Yesterday the company was in the news again with reports that former AOL chief Jon Miller is seeking capital to purchase YHOO outright for a price that is reported to be in the $20 range.

YHOO shares rocketed higher on the news, immediately jumping up by nearly $1 per share, or approximately 10%.

My initial reaction, as you might expect, was skeptical. Jump on this news as a chance to dump shares. Management at YHOO, with or without Chief Yahoo Jerry Yang, has destroyed shareholder value so much that it would be hard to believe that anyone would pay a premium for the stock.

How could it be that a lone ranger from the failed AOL model be considered a serious alternative to YHOO going it alone? It makes no sense until you take a closer look at YHOO fundamentals. There the story starts to get a little more interesting.

We may have broken the ultimate barrier to diversity with the election of the 44th President of the United States Barack Obama, but the ranks of minorities in top positions at Fortune 500 companies remain thin and are steadily declining.

Late Monday, Symantec (NASDAQ: SYMC) CEO John Thompson announced plans to retire from the post in March, but will remain on as chairman. Also planning to move out of the corner office until a replacement is found is the CEO of struggling Web portal Yahoo (NASDAQ: YHOO), Jerry Yang.

Their pending exits continue a string of other high-profile minority CEOs over the past year due to various reasons, ranging from Dick Parsons at Time Warner (NYSE: TWX), to Stan O'Neal at Merrill Lynch (NYSE: MER) to Alwyn Lewis at Sears (NASDAQ: SHLD) and William Perez at Wrigley.

After a short and tumultuous tenure as CEO of the company he co-founded, Jerry Yang and Yahoo!, Inc. (NASDAQ: YHOO) announced this evening that Yang will step down as CEO as soon as a successor is found. Carl Icahn is certainly happy, as are the YHOO investors who saw Yang refuse Microsoft Corp.'s (NASDAQ: MSFT) $33/share buyout offer earlier this year. Yahoo! shares closed today below $11.

It's a forgone conclusion that Yahoo! will immediately begin searching for a new CEO. The internal list probably includes just one person -- Yahoo! President Sue Decker. She has ruled the Yahoo! kingdom alongside Yang for the last 16 months and is easily qualified for the position. She also does not seem to bear the blame for failing to consummate the proposed Microsoft merger almost 10 months ago.

This is a precarious time in Yahoo!'s future -- it needs a CEO that can unwrap Yahoo!'s magic once again and get customers -- and the market -- interested in the company again. Yahoo! still has great products and a great brand, but it has tarnish that needs to be wiped away.

Google, Inc. (NASDAQ: GOOG) has stolen any remaining thunder that Yahoo! may have once had. Now Yahoo is seen as an incredibly popular but stodgy company that just doesn't have the cutting-edge position it used to hold in the internet.

It's hard to see how a new CEO can totally re-invent the company. But anything is better for Yahoo! than where it sits now. Yang can go back to his old position as "chief Yahoo!" and rally the troops -- that is, if any of them are even loyal to him any longer.

For some reason this morning several high profile stories I have been ranting about in recent months have floated to the top of the headline heap again.

I just read that Yahoo! (NASDAQ: YHOO) CEO Jerry Yang is ready to return to the bargaining table with Microsoft (NASDAQ: MSFT) stating: "To this day, I believe the best thing for Microsoft to do is to buy Yahoo," Yang said Wednesday evening at the Web 2.0 summit in San Francisco.

ARE YOU KIDDING ME?! This has to be one of the biggest jokes in the investment world -- unless you are a Yahoo! shareholder. It was only last week I posted Yahoo rejects $30 to buy itself for $12?

Microsoft could now offer a 20% premium to today's stock price and still buy Yahoo for half what it offered last January. What do they say -- "good things come to those who wait". This is certainly a screaming example.

I would love to be in the conference room or on the call when Microsoft offers up a few crumbs to bail them out of a sticky situation. I was against MSFT doing the deal for a bloated price before, but it might make sense now. It could buy the company, and with Wall Street titan and M&A guy Carl Icahn on board, slice and dice this thing so that it cost them next to nothing to get the search advertising part of the company they coveted.

Yang looks like a child playing with grown-ups and his biography is taking one hit after another. Good thing he does not need food money and will never have to work again no matter what happens. By contrast, if Yahoo! took the $44 billion it would have been the deal of the year and Yang would look brilliant again. If I was a shareholder I would be really, really steamed!

Sheldon Liber is the CEO of a small private investment company and the principal for design and research at an architecture & planning firm. He writes the columns Chasing Value and Serious Money. Disclosure: I do not own shares of MSFT or YHOO.

I once worked for an ex-Yahoo! employee, and he conducted most of his business in lower-case. That's not, however, how he laid people off. In an email to the whole company today after Yahoo! (NASDAQ: YHOO) reported earnings were down 64%, CEO Jerry Yang announced he would be laying off 10% of the workforce "in the next several weeks." Net income reported was $54 million for the third quarter of 2008, compared to $151 million in the third quarter of 2007, with revenue of $1.325 billion. The company met expectations of nine cents per share.

"we understand that hearing this news now creates uncertainty, but we are moving ahead in a way that balances speed with a clear focus on accomplishing what is necessary to set the organization up for long term success," Yang wrote. At the rate the company has made change over the last few years, I hardly expect brilliant things. Long-term success? Investors would probably settle for "not making pathologically boneheaded mistakes that cost the company 70% of its stock price" at this point.

Yahoo! (NASDAQ: YHOO) will be reporting earnings for the third quarter on Tuesday, October 21. The internet portal hasn't had a great year so far. According to data at Earnings.com, the company hasn't seen too much in the way of bottom-line growth. And the stock is, as of this writing, at the low end of its 52-week range. Of course, just about all stocks are having a rough time this year. Then again, Yahoo! could have avoided all this misery and just allowed itself to become assimilated into the Microsoft (NASDAQ: MSFT) culture. Poor CEO Jerry Yang. What was he thinking?

The call is for Yahoo! to post at least $0.09 per share for the bottom line. It would be nice if management could go beyond those expectations, since the company posted $0.11 per share in the year-ago period. Yahoo! really needs to show the market that it can stay relevant and keep up with the likes of Google (NASDAQ: GOOG) and Time Warner's (NYSE: TWX) AOL. Google recently booked a quarter that went well beyond the thinking of analysts. Yahoo! has a relatively decent history of beating earnings expectations, but it did miss the call last quarter, according to AOL Finance. So there's going to be a lot of pressure on Yang to perform.

Of course, let's be honest. The earnings, in the big picture, don't really matter. Yahoo! is essentially, in the minds of many, still an arbitrage play. In fact, Tobias Buckell recently commented on this subject. There are a lot of investors out there who would like to see Microsoft CEO Steve Ballmer come back to the table to begin a new round of negotiations for a takeover of the portal. I, for one, wouldn't want to see that. Does Microsoft really need the headache of integrating the web company's brand assets with its own? No. However, looking at it from the perspective of a Yahoo! shareholder, I obviously see why a buyout would be attractive. That might be the only way for the stock to command any premium these days.
