OMAHA, Neb.–(BUSINESS WIRE)–The Investor Movement Index® (IMXSM) increased to 7.55 in February, up 9.26 percent from its January score of 6.91. 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 four-week period ending February 26, 2021 ranks “Moderate High” compared to historic averages.

“The continued rally in February matched our clients’ behavior in taking on more exposure to the markets, particularly the S&P 500,” said JJ Kinahan, chief market strategist, TD Ameritrade. “TD Ameritrade clients favored buys in Information Technology, Healthcare, and Consumer Discretionary stocks in February, with many driven by the cooperative monetary policy still being laid out by the Fed. Our clients did seize some selling opportunities during the period as well, as some vaccine makers and other pandemic mainstays hit all-time-highs.”

The S&P 500, Dow Jones, and the Nasdaq Composite all hit record highs during the period, helped by optimism around new stimulus measures and after Federal Reserve Chairman Jerome Powell reiterated his intention to maintain ultra-low interest rates and continue the bank’s asset-purchase policies. Also helping move markets higher was the possibility of another COVID-19 vaccine option, this time from Johnson & Johnson (JNJ).

In February, TD Ameritrade clients were net buyers of equities and net buyers overall. Some of the popular names bought during the period were:

  • Apple Inc. (AAPL)
  • Palantir Technologies (PLTR)
  • Qualcomm Inc. (QCOM)
  • Tesla Inc. (TSLA)
  • AMC Entertainment Holdings Inc. (AMC)

TD Ameritrade clients did find some names to sell during the period, including:

  • Moderna Inc. (MRNA)
  • BioNTech SE (BNTX)
  • Novavax Inc. (NVAX)
  • Zoom Video Communications Inc. (ZM)
  • Alibaba Group Holdings (BABA)

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.
