Here's a link to a PDF copy of an article by Burton Malkiel (author of "A Random Walk Down Wall Street") in which he says that he remains a believer in the efficient market theory. I picked the link up from a poster named "Kathyet" at the NFB site (she said that she picked it up from TMF). I don't agree with Malkiel. But I think that it is helpful for those trying to make sense of the SWR discussions to have access to such a strong statement of the argument in support of the efficient market theory from such a long-time proponent of it.

My take is that index funds are a better choice than individual securities in many (but not all) circumstances. At today's valuations, my inclination is to limit purchases of both individual securites AND broad indexes until valuations have returned to more moderate levels. I don't say that most investors should exclude stocks from their portfolios. I think that the average investor can afford some investment in stocks even at today's price points. But I don't think that it is reasonable to expect to see the same sorts of long-term returns starting from today's valuation levels as one could expect from a starting point at which more moderate valuation levels applied.
