In expectation that Cray Research Inc will announce its forthcoming multiprocessor supercomputer within the next 40 days, Goldman Sachs & Co analyst Daniel Benton has put the company on his list of highly recommended issues – and the shares obligingly leaped $4.50 to $78 even in Tuesday’s trading. The list embraces the most compelling stocks that the firm recommends to investors. The shares in the supercomputer builder have been depressed since IBM announced that it would be bankrolling the new firm formed by former Cray Research designer Steve Chen.
