TD Ameritrade Investor Movement Index: IMX Rises in September

IMX moves up 3% in September despite month’s market volatility

The Investor Movement Index® (IMXSM) moved higher to 8.66 in September, up from 8.38 in August. The IMX is TD Ameritrade’s proprietary, behavior-based index, aggregating Main Street investor positions and activity to measure what investors actually were doing and how they were positioned in the markets.

The reading for the five-week period ending September 24, 2021 ranks “High” compared to historic averages.

“After seeing record highs across all indices recently, we saw a September slump hit the markets at the end of the month,” said JJ Kinahan, chief market strategist, TD Ameritrade. “While market volatility was elevated compared to recent levels, TD Ameritrade clients used this volatility to help make their investment decisions. As we hit new highs to start September, clients saw this as an opportunity to sell equities and the ensuing pullback as a buying opportunity.”

Equity markets were highly volatile over the September period, driven by global economic concerns and continued supply chain issues. Investor concerns had been slowly building up leading into September and finally led to strong selling across the three major indices. All major sectors moved lower over the month except the energy sector, which benefited from a rise in the price of crude oil amid supply concerns. After selling off initially, the S&P 500 attempted to rally back only to make another gap lower. This drop snapped a seven-month streak of positive gains, leaving the potential to finish positive for the 3rd quarter.

TD Ameritrade clients were net buyers of products overall during the September IMX period, increasing their holdings of equities and fixed income assets. Some of the popular equity names bought during the period were:

  • Apple Inc. (AAPL)
  • Alibaba Group Holding Ltd. (BABA)
  • Ford Motor Co. (F)
  • Nvidia Corp. (NVDA)
  • SoFi Technologies Inc. (SOFI)

TD Ameritrade clients took advantage of rising prices to sell some equities during the period, including:

  • Tesla Inc. (TSLA)
  • Netflix Inc. (NFLX)
  • Amazon.com, Inc. (AMZN)
  • American Airlines Group Inc. (AAL)
  • Delta Air Lines, Inc. (DAL)
  • Bank of America Corporation (BAC)

About the IMX

The IMX value is calculated based on a complex proprietary formula. Each month, TD Ameritrade pulls a sample from its client base of funded accounts, which includes all accounts that completed a trade in the past month. The holdings and positions of this statistically significant sample are evaluated to calculate individual scores, and the median of those scores represents the monthly IMX.
