There is no set time for inclusion to begin. It just trickles over time. In about 6 months you'd be safe to say most have take a position in COLE. If you look at HTA, which went public a year ago, you'll see huge inclusion positions: http://finance.yahoo.com/q/mh?s=HTA+Major+Holders
It makes sense that COLE will be near $14 when this happens.
