3i Group is buying opportunity after 40% underperformance, reckons Citi

3i Group PLC (LSE:III), the FTSE 100 investment company whose fortunes are closely tied to European discount retailer Action, has been put on an "upside catalyst watch" by Citi, which argues the recent share price slump has created an attractive entry point for investors. The shares hit an all-time high of almost 4,500p in October and have fallen around 40% since.
