There is a fallacy in this user survey. That 59% of readers believe monetary policy is the cause does not mean they are right. If you read the article by Professor Damadorna's blog Musings on market post from last year, he makes a compelling case that in fact low rates/monetary policy only accounts for up to 10% of the stock valuations and that the other 90% are mostly company-specific related pure valuation metrics. It would be interested to see if the 'wisdom of crowds' is right or wrong on this issue.
