James Montier, senior investment strategist and partner at Boston-based fund manager GMO, says the holding pattern the market has been in for the past two months – not up, not down, mainly sideways – creates a danger that investors might be swallowed by their biases.
If you’re bearish, you’ll find the data that supports your view. If you’re bullish, you’ll do the same. The danger, Montier says, lies in ignoring alternative views – and failing to build a portfolio robust enough to hold up even if your view is wrong.
