The stock market is overbought going into the seasonally weak summer season. It will decline taking most stocks, including Disney, with it. It is not a good time to load up on any stock trading at its 52 week high. Better entry prices will be forthcoming.
Its easy to buy stocks, selling is the hard part. It might pull back or you might leave a bunch on the table. That's what makes it a challenge. I think DIS is a hot stock right now and I am sticking with it. Not saying I am right but that is what I am doing. FYI, there were people saying it was overdone at 45. those people lost a 40% gain.
While it is true that the market usually seems to have a seasonal pullback during the summer months, for the reasons that robpic5 has listed, I'd be weary about betting against Disney this summer. That's not to say that it won't happen, but I'm personally putting my money in for the long haul. With Disney pushing out more blockbuster hits in the near and distant future, this move has the potential to be a rebound phenomenon making those that don't position themselves to reap the benefits of these moves now cry themselves to sleep at night. As the market and economy in America are clearly looking healthier than a year ago, people will begin to spend more money in the leisure and entertainment categories. I'm personally looking for 10 years highs (if not an even more impressive records) for attendance at Disney World and at the box office this summer.
While it is possible (maybe even likely) that the market takes the usual summer pullback, I'd be weary in waiting for better prices with Disney. I personally see this as a fundamental shift with no reason for a pullback. When/if the summer pullback happens in the market, you may find that this move is overshadowed by new blockbuster and theme park sales. While it may be possible to wait it out and buy in at ~$60 a few months from now, wouldn't you rather lock in now for what MAY send us to $80+? Gotta think about the opportunity cost here. Are the profits you might gain from waiting worth the profits you might lose in waiting?
Food for thought.
