Charles Schwab (SCHW) has announced its decision to acquire optionsXpress (OXPS) in a friendly all-stock deal. This deal will help Schwab compete with other firms like E-Trade (ETFC), Ameritrade (AMTD), and Bank of America (BAC), which all have large online brokerage services and are vying to provide investors with the best tools and services.

The deal, which is expected to close by the third quarter of 2011, will cost Schwab $1 billion, and the company will issue 60 million new shares to swap each outstanding share of optionsXpress with 1.02 of its own shares. Our $19.74 price estimate for Charles Schwab is at a premium of almost 12% to its current market value.

Option volume has ramped up today on KeyCorp (KEY), with activity rising well beyond the usual level on both the call and put side of the tape. Taking a closer look at some of the major block trades on this regional banking issue, it appears that a single spread strategist is responsible for a healthy portion of this option volume.

Specifically, the trader purchased a block of 10,000 June 10 calls for $0.50 each, and simultaneously sold 10,000 June 8 puts for $0.25 each. The result was a net debit of $0.25 per pair of contracts -- which means the speculator can begin collecting profits on those purchased calls if KEY rallies beyond $10.25 by June expiration.

"Merger Fund (MERFX) offers a non-traditional way to invest, using merger arbitrage," says fund specialist Leonard Goodall.

The editor of No-Load Fund Portfolios explains, "Managers Green, Shannon and Behren focus on acquisitions. The success of the fund depends upon the skill of the managers to pick the mergers that will go through, along with a good measure of luck.

"They make us of the 'spread' -- buying shares in the target company after the acquisition is announced and selling those shares at a higher price when the deal is completed.

Rumor has it -- again -- that dot.bomb era survivor E*Trade (ETFC) may be acquired by none other than Charles Schwab Corp. (SCHW) for an initial offer of $24 a share. This chatter moved the stock price marginally Friday up 72 cents to $15.27. Although as of Monday morning the rumors are unsubstantiated, trading in stock options has heated up on the call side.

Bantering about the inevitable acquisition of E*Trade has been an annual pastime on and off for the past 10 years, but they resurfaced again in earnest after the financial crisis creamed most companies and institutions. E*Trade is currently capitalized at $3.37 billion. If the rumors bear fruit, the Schwab offer represents approximately a 60% premium to the current price.

The fact that there hasn't been any action in a while doesn't mean there isn't room for more. Richard Anderson, CEO of Delta Airlines (DAL), says that the airline industry could consolidate further -- not exactly a shock in an industry that is known for universal financial suffering. He notes, "If a transaction were to occur, economics should prevail."

The only concern, of course, is whether the Obama administration would sign off on any future deals. Anderson believes, "I think the case can be made ultimately, but it remains to be seen what this administration's take will be."

Two big reinsurers in Bermuda could be getting ready to tie the knot. Aspen Insurance Holdings (AHL) is said to be close to buying Ariel, which would be a multi-billion dollar merger.

According to Reinsurance magazine, the companies are "close to signing a merger agreement." None of the financial details have been disclosed yet, but the result would create the largest combined Bermuda and Lloyd's reinsurance operation on the island.

Up until the credit crisis, private equity firms had it made. They had plenty of leverage to play with and could load up their acquisition targets with it. So, they could realize a fantastic return on equity, mitigate their own risks, and show that they were the studs of the Street.

Then, all that went away. Credit markets dried up, and private equity companies lost their acquisition fuel. The numbers aren't as big as they used to be, but it looks like the private equity market is back in action.

Twitter's much-hyped $100 million round of financing closed Friday, cementing the company's (illiquid) value at $1 billion, though Twitter itself would not confirm the amount. T. Rowe Price and Insight Venture Partners participated in the deal, as expected, which is believed to be a precursor to an eventual liquidity event -- such as an IPO or acquisition.

In a way, it feels like 1999, where you have investors rushing to invest in high-profile companies, despite the absence of revenue models. Yet, Twitter may not be as bad off as the traditional folks think, especially if the goal is an acquisition. The company does say that it's pursuing revenue via corporate accounts. But, it's been saying this for a while, and we haven't seen anything yet. Also, it's leaving open the possibility of running ads on the site, though this wouldn't happen within the next three months.

Some people join wine-of-the-month clubs. There are plenty of other programs out there, too, where your credit card is hit every month, and your purchase is sent to you directly. If only such programs were available for Google (NASDAQ: GOOG). . . .

The company's CEO, Eric Schmidt, said Wednesday that Google plans to pick up a small company a month as a way to get its acquisition head back in the game. With the worst of the recession behind us, Google believes, this is a great way to get moving.
