If you are familiar with options, that is an easy way to own it at a lower and get paid for it, along the way.  And that way, you don't get caught with a short hurting you, should it continue to rally.   You can sell it naked, say, at 46.  Then the stock will get put to you at that level if it is below there on expiration.  But you will have gotten paid for it, by the put premium.   The broker will hold margin equal to owning the stock, but since your intention is to own it, anyway, that may not be a big deal.  Alternately, if you don't want all that margin held, then sell a put credit spread.  You get a lot less premium for that, but it's a lot less margin.
