The IMX is TD Ameritrade’s proprietary, behaviour-based index, that aggregates Main Street investor positions and activity to measure what investors were actually doing and how they were positioned in the markets.
Singapore-based investors, at least those who trade with TD Ameritrade, sold more than they bought in June, reflecting their stance on recent market volatility.
The brokerage, citing its Investor Movement Index (IMX), notes a score of 4.88 for its Singapore clients in June, versus 5.74 recorded in the preceding month.
