Rising Star Buy: A Jobs-less Apple Is Still a Good Buy
Perhaps you heard something this week about Steve Jobs stepping down as CEO of Apple (Nasdaq: AAPL). Perhaps you wondered how Fools were reacting. Motley Fool Rising Star analyst Jim Mueller -- whose real-money portfolio aims to "take advantage of nonsensical expectations" -- is using the opportunity to make a third purchase of Apple stock.

"The Apple of today is the same company as it was yesterday, the last quarter, and much of the last year," Jim wrote. "Tim Cook, Apple's new CEO, has held that position in all but name since January, when Jobs took a medical leave of absence."

5 Stocks for the Greedy Investor's Watchlist
Recent market volatility has pushed many safety-seeking investors into the open arms of dividend-paying companies and the shiny arms of gold. Fool contributor Brian Stoffel reminds us that success can also result from looking for aggressive growth companies that have been whacked by the market.

Brian starts his new monthly series by showcasing five stocks he's considering buying this month. Each stock has seen its price decrease over the past month or so, ranging from -21.7% for Zipcar (Nasdaq: ZIP) to Travelzoo's (Nasdaq: TZOO) -42.5%.

Zipcar isn't profitable yet, he acknowledges. It "costs a lot of money to buy and lease cars to expand a fleet; but because Zipcar sees an incredible opportunity presenting itself in cities across the country, it is willing to endure some short-term pain for long-term market-share gain."

Can CEOs Save the Economy?
Starbucks (Nasdaq: SBUX) CEO Howard Schultz earned Foolish praise for his suggestion that corporate America stop political donations until Washington makes some real progress.

"If CEOs and businesses cut off their financial support to politicians, maybe politicians would have a little more incentive to get things done," Alyce Lomax wrote. It's since been reported that more than 100 business leaders have joined Schultz's pledge to boycott U.S. political campaign donations.

In the broader picture, Alyce notes that "shareholder advocates have been increasingly pushing for transparency in corporate campaign donations." Sprint Nextel (NYSE: S) and AT&T (NYSE: T) are among the companies that have fielded shareholder proposals regarding political spending.

In Alyce's view, "trying to sway the marketplace through political influence is no competitive advantage and defies free-market principles." Read the article for more on this very Foolish issue.
