Will Facebook save the market? Thoughts? -- I would vote no. I think the focus is solely on the European debacle. If Greece leaves the EU and there is going to be a similar move like we saw last year. Facebook's a nice story buy it doesn't have any real weight to carry the market -- True. This ia a fickle market. -- Since this is such a headline driven market and we're near a psychological low, 1300 SPX, maybe Facebook will renew bullish enthusiasm and help reverse the down trend Thoughts? -- Can Facebook's Debut Survive Such a Volatile Market? 12 hrs ago - CNBC.com For Facebook to live up to its larger-than-life public image, it will have to withstand a broader stock market where the overwhelming pressure is heading downward.

So, too, can good, well-run companies in industries that are out of favor with investment pundits generally have surprisingly low multiples. All the more reason why investors would do well to have a range of sources (in addition to their own investigations) for investment ideas.
