Apple Mulling STAKE In Twitter and 3 Top Weekend Headlines to Know

Carl Icahn’s investment in the truck-maker Navistar International Corporation (NYSE:NAV) just rose to 14.95 percent, which is just under the 15 percent threshold that would trigger the company’s new anti-takeover measures. However, there are no indications regarding Icahn’s plans for Navistar, and his stake is roughly the same as that of the fellow activist and former adviser Mark Rachesky, who currently holds14.9 percent himself. The majority of Navistar shares are concentrated in only a few holders.

Apple, Inc. (NASDAQ:AAPL) is said to be mulling a stake in Twitter. Recent talks are reported to have involved “an investment in the hundreds of millions” which would value Twitter at $10 billion, well above the $8.4 billion valuation it received in 2011, when peer valuations were higher. Apple and Twitter may well be on friendly terms, as iOS 5 brought with it Twitter integration capabilities, but iOS 6 will also allow Facebook (NASDAQ:FB) integration, and Apple and Facebook have some mutually exclusive plans.

BHP Billiton Ltd. (NYSE:BHP) announces to those outside the company that a decision to go ahead with the proposed A$30 billion (US$31.3 billion) expansion of its Olympic Dam mine will be postponed by two years, according to the Weekend Australian from its website on Saturday, citing documents.

Investors who hope that Prem Watsa will use his 9.9 percent investment in Research In Motion (NASDAQ:RIMM) to insist that the firm be acquired or any other sort of “strategic alternative” are going to be disappointed, as the Canadian value investor is insists that his stake in RIM marks a “long-term investment,” and doesn’t believe the company’s embattled situation requires a buyer or even a partner. He’s states his confidence in Thorsten Heins’ leadership.
