IBM was at low 180's when slowly but surely they started pushing IBM up. Now that it is headed to high 190's, it is time to take profits and short IBM down to 170. IBM has had 7 consecutive declining revenues. Nothing seems to be working. The deal with IBM is not a savior either. It is probably better for APPL than it is for IBM. With all that said, shorting IBM here is probably a reasonable bet.
Just released 13F-HR (quarterly holdings): Buffett bought another 1.8 million shares of IBM during the last quarter, $12.7 billion value at the end of June. Buffett is that dumb guy that runs Berkshire Hathaway, whose share price went over the $200,000/A share mark today. :-)
