It looks like we are certainly en route to Dow 18,000. May even happen by 2015, or possibly sooner. But, without a pullback? I doubt that. Just because we are breaking records this year, doesn't mean a pullback will not possibly happen at all this year. I still expect a pullback of some amount this month or by late June. If it does not happen, then I go 100% to cash, and start building long positions with a buy on the dip strategy.
Until then, I will continue to marvel over the growth of my retirement accounts. Maybe 401K plans will be the next great bubble!
