Investors and Pollsters

According to a new (ahem, wildly self-serving) study from market research MORI as cited in today’s FT, reduced customer satisfaction, as reported by market researchers, presages a downbound company stock by as much as twelve months. I have not yet read the original study, so I can’t say much beyond the obvious, that this is sort of thing is fraught with problems, ranging from timing (what if the stock doubles before it collapses?) to causality.
