In the following video, Motley Fool analyst John Reeves gives us his weekly wrap-up, discussing three companies that cratered this week. He tells us how Herbalife (NYSE:HLF) took a big hit after one analyst came out and called it a pyramid scheme, tells us why Markel (NYSE:MKL) fell after announcing it would be buying Alterra Capital (NASDAQ:ALTE), and discusses Research In Motion (NASDAQ:RIMM), which had been back on the rise, but fell this week after news from its conference call, saying that the company's vital service revenue may come into question next year.
Research In Motion has seen its once mighty market share bleed away, largely thanks to Apple. There's no doubt that Apple is at the center of technology's largest revolution ever and that longtime shareholders have been handsomely rewarded, with more than 1,000% gains. However, there is a debate raging as to whether Apple remains a buy. The Motley Fool's senior technology analyst and managing bureau chief, Eric Bleeker, is prepared to fill you in on both reasons to buy and reasons to sell Apple, and what opportunities are left for the company (and more importantly, your portfolio) going forward.
