NEW YORK (TheStreet) -- Glencore (GLCNF) continues to bother Jim Cramer.

He told a viewer via Twitter he's not assuaged by the Swiss company's 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) - Get Report,"' 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.

Another viewer asked what other stocks might impacted by the recent developments at Volkswagen. Cramer, portfolio manager of Action Alerts PLUS, said the charitable trust did trim its position in Honeywell (HON) - Get Report because of its turbo business but he'd like to buy the stock again when the opportunity is right.

Cramer was also asked if Amgen (AMGN) - Get Report is a good buy and he responded that Amgen, Biogen (BIIB) - Get Report, Celgene (CELG) - Get Report, Regeneron (REGN) - Get Report and Gilead (GILD) - Get Report have all come down to levels where they are worth a look. Cramer said buy some now and if the stocks go lower, buy more.

Another viewer asked with Skyworks Solutions (SWKS) - Get Report would benefit from the new iPhone and the Internet of Things. Cramer said he likes Skyworks, which has come down a lot in price. Finally, a viewer asked once Facebook (FB) - Get Report or Google (GOOGL) - Get Report takes over Twitter's (TWTR) - Get Report 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.

At the time of publication, Cramer's Action Alerts PLUS had a position in FB, GOOGL, HON and TWTR.
