It has been up over 15% in the last month. Look at its chart and check out the bollinger band. It is poised to drop below 27 soon and even go below 25. Don't be fooled by its short time strength. Tech stocks surprise you by their sudden drop. The same thing that is happening to ADI will happen to TXN.
When I posted this TXN was at 27.38. It should crack hard soon and go below 26.60 today. Those who pushed it higher today will sell at close. Front run them.
