The stock is expensive at roughly 23 times forward earnings, but it is the best of the smaller brokerage firms. Instead of trying to compete with Goldman Sachs ( GS) for the big deals, Jefferies focuses on doing business with small and midsized companies, where it can dominate. Do you think Lucent (LU) should be sold into this rally created by the Alcatel (ALA) news? -- Trevor from Iowa Jim Cramer: Yes, I believe that makes sense. Even if a merger with Alcatel does go through, I doubt Lucent shareholders will receive a very big premium. Unfortunately, Lucent has been a serial disappointer, and I think the company's long-term health obligations could be an issue when it comes to pricing a potential deal. Want more Cramer?
