UPDATE: Raymond James Upgrades Telephone & Data Systems

In a note released Tuesday, Raymond James analyst Ric Prentiss upgraded shares of Telephone & Data Systems TDS from Outperform to Strong Buy and raised the price target from $37 to $39.

Telephone & Data Systems closed Tuesday at $25.55, up 8.8 percent.
