Consider what Jim Cramer himself is telling you. He will not buy or sell a stock within 5 days of mentioning it on the show. Now, inherent in that statement what he's also telling you is that for a long-term portfolio he doesn't need to act any faster than that. In fact, he can gain valuable insight into the stock based on how it performs after it is mentioned on the show. For example, if a stock jumps after he mentions it, and every time it does try to dip back new buyers come in and bring the stock back up, that is an indication that his thesis - possibly long-term - but now more importantly in the shorter term - may very well be "right on the money", and possibly a good time to initiate a position.
If, however, the stock merely jumps and falls right back with little or no new buying interest coming into the stock, that is also just as telling that perhaps this stock is just not ready yet, and now anyone who jumped aboard into the spike will bring the stock lower as they all liquidate their positions at increasingly losing prices. These will likely be the same people who the go on to send Cramer hate-mail. When all of this pressure capitulates into a panic in the stock, THAT is the time to consider your long term stock purchase/investment!Here is an interesting trick that I've just come across regarding credit cards that can be played on you! Apparently, by law, you have only 60 days in order to make a claim dispute on a particular credit card charge that may appear on your statement.
