Abstract

The instabilities of the world economy have greatly affected the Vietnamese stock market. Changes in macroeconomic policies, effects of the tight-money policy, banking bad debts, flows of credits to brokers, and regression in realty market bring concerns rather than expectations to investing community. These issues considerably influenced transactions in the Vietnamese stock market in the first quarter of the year and caused falls in VN-Index. On May 25, 2011 VN-Index was down to a record low of 386.36 points in the first two quarters. This has profoundly influenced the mentality of investors and increased herding behavior on the market transactions.
