When valuations on blue chip stocks change, there is rarely a chance to get back in unless the market hiccups. See MCD from 2009, when it went through a valuation adjustment based on over-sea's consumption.
DIS is beginning to get a premium price to earnings valuation based on it's content, which is in high demand. There also may be a bidding war soon, as Apple and Google begin battling for TV content supremacy.
You will see maybe $1.00 corrections here and there, but nothing protracted that will give you a good entry. Look for 70-90 in 18 months with no external market events.
