Jim Cramer answered viewers’ Twitter(TWTR) questions from the floor of the stock Exchange Tuesday and said he's not assuaged by Glencore's(GLCNF) comments that it is ‘operationally and financially robust.' On Tuesday, Glencore’s stock rebounded somewhat from Monday’s big decline. 'Glencore is the situation I am most worried about other than Volkswagen(VLKAY) and Petrobras,(PBR)' said Cramer. 'They have too much debt, maybe it's $50-billion. And you know what? This could be Long Term Capital, it's one of the reasons I'm worried.' Cramer was referring to Long Term Capital Management, an over leveraged hedge fund that ultimately received a bailout. One viewer asked what other stocks might impacted by the recent developments at Volkswagen. Cramer, who's portfolio manager of Action Alerts PLUS, said the charitable trust did trim its position in Honeywell(HON) because of its turbo business, but he'd like to buy the stock again when the opportunity is right. Cramer was also asked in Amgen(AMGN) is a good buy and he responded that Amgen, Biogen(BIIB), Celgene(CELG), Regeneron(REGN) and Gilead(GILD) have all come down to levels where they are worth taking a look at. Cramer said buy some now and if the stocks go lower, buy more. Another viewer asked with Skyworks Solutions(SWKS)would benefit from the new iPhone and the Internet of Things. Cramer responded that he likes Skyworks, which has come down a lot in price. Finally, a viewer asked once Facebook(FB) or Google(GOOG) takes over Twitter's news feed formula, will Twitter fade out like MySpace? Cramer said Twitter ultimately does have a franchise, and it has a good balance sheet, but the company still has more work to do. Send your Twitter questions to @JimCramer, using #CramerQ.
