Valuation-Informed Indexing #611: Even Prior to Shiller, There Was No Research Showing That Market Timing Doesn’t Work

I’ve posted Entry #611 to my weekly Valuation-Informed Indexing column at the Value Walk site. It’s called Even Prior to Shiller, There was No Research Showing That Market Timing Doesn’t Work.

Juicy Excerpt: So market timing is required. Those who follow the peer-reviewed research have known this for 41 years (Shiller published his research showing that valuations affect long-term returns in 1981). So why do claims that market timing always works and is always required inspire controversy (trust me – they do)? These are obviously true claims.
