"The technical backdrop has taken a distinctly bullish turn," says Michael Ashbaugh in MarketWatch's The Technical Indicator. Here, he looks at the market averages and a trio of stock ideas.

"Perhaps most obviously, the S&P has staged a 10-to-1 rally, and a 28-to-1 spike, from its 200-day moving average. And by any measure, this raises a bullish technical flag.

"With a gravity-defying rally, the S&P extended its gains, clearing resistance at 930 last Thursday. From current levels, significant resistance holds at the 2009 closing high of 946 while initial support rests at 930.

"Meanwhile, the Dow's near-term view is similar. With this week's rally, it's staged a 'V'-shaped reversal, breaking to one-month highs. Looking ahead, significant resistance holds at 8,799 - matching the 2009 closing high - while support rests at 8,580, matching the breakout point.

Foundry Networks, Inc. (NASDAQ: FDRY), which builds networking technologies, went public in 1999. With the Internet surge, the stock price went over $200.

Of course, that was a temporary thing. Since then, Foundry's shareholders have suffered.

However, this week they got some cheery news. Foundry agreed to sell out to Brocade (NASDAQ: BRCD). The deal comes to about $2.91 billion in a combination of cash and stock.

Essentially, the deal blends some key technologies. While Brocade has a strong footprint in fiber channel systems, Foundry is a top player in switches and 10-gigabit Ethernet offerings.

If anything, it's a necessary step to deal with the intensely competitive environment, especially against the mighty Cisco (NASDAQ: CSCO).

No doubt, Brocade has demonstrated success with M&A, such as with its acquisition of McData. However, networking deals can be tricky. After all, Brocade operates primarily on an OEM basis whereas Foundry has a large direct sales force.

There is some financial risk too as Brocade needs to borrow about $1.4 billion.

Foundry Networks (NASDAQ:FDRY) is up over 30% on a buy-out by Brocade (NASAQ:BRCD). Brocade is off nearly 20% on the same news.

Apple (NASDAQ:AAPL) is off 10% on a weak forecast for the next quarter.

Wachovia (NYSE:WB) is off 12% on poor earnings and a dividend cut.

American Express (NYSE:AXP) is down over 10% after reporting a weak quarter.

Texas Instrument (NYSE:TXN) is off over 10% on poor numbers.

Shares may trade differently in the pre-market than they do in the regular session.

Before the bell: Futures mixed ahead of Bernanke (LEH, SPLS, TOL)

With the Apple (NASDAQ: AAPL) conference just around the corner, analysts expect several features from the new iPhone that will likely be announced during the conference. The first is of course the 3G capability, which would boost iPhone sales in Europe and quell complaints about the speed of download through the AT&T (NYSE: T) network. The second is the corporate email capability. A third feature will likely be iTunes downloads through cellular networks and the applications store. Also, some expect Apple to try a different business model including subsidies and multiple carriers.

FedEx Corp. (NYSE: FDX) said it plans to change the FedEx Kinko's name to FedEx Office and take a related charge of nearly $900 million. The company said the name change will better reflect the services that it provides at its retail centers. Perhaps FedEx is right, but Kinko's is a well established brand and I find it hard to believe someone doesn't know what Kinko's is all about. FedEx also said it would raise its quarterly cash dividend by one penny, to 11 cents a share payable July 1 to shareholders of record as of June 13.

Goldman Sachs cut Consolidated Energy (NYSE: CNX) and Peabody Energy (NYSE: BTU) to "neutral," according to MarketWatch. The financial website also reports that UBS upgraded Senior Housing (NYSE: SNH) to "buy."
