I hate when Cramer does this...
You basically have two options:
(1) allocate half of your capital on Monday and wait about three to four weeks to allocate the other half.
(2) wait about three to four weeks for it to retrace most of the short-term gain.
Why? SLM will probably open above $7 and may hit $7.50. There will be some price decay from the day's peak.
I have nothing against Jim Cramer. I bought several stocks in his three risk groupings recommended at the beginning of 2007. "Mad Money" creates a herd reaction. If you miss the episode when he hits the "sell, sell, sell" button, you will be in trouble.
Here is another reason: http://online.barrons.com/article/SB123397107399659271.html
BTW, I sent an e-mail to the show in early 2007 seeking his opinion on Energizer Holdings. The stock was in the low 80's at the time. I have been and will always be a shareholder since Day 1 - a spinoff from Ralston Purina. I am an "enterprising investor" as defined by Ben Graham, one who focuses on (1) relatively unpopular large companies (2) bargain issues; and (3) workouts. I bought RAL because it was divesting (3). I viewed ENR as unpopular (1) and a bargain (1). ENR is a business very much like PG, a business model that Buffett likes to invest in.
I got an e-mail from his producer to call at a specific day and time in May, 2007. Cramer discussed it alright, but the price had already risen to the upper $90's, maybe closer to $100. His target - $120. The shares rose to over $118.
It might be better own a stock he recommends and then you sell, rather than to buy one he recommends and then try to sell higher.
