TD Ameritrade Investor Movement Index: IMX Begins 2020 on High Note

The January IMX rose to its highest score since October 2018

OMAHA, Neb.–(BUSINESS WIRE)–$AMTD #TDAmeritrade–The Investor Movement Index® (IMXSM) increased to 5.68 in January, up 2.34 percent from its December score of 5.55. 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.

Though the January IMX score reached its highest point in 15 months, the reading is considered “Middle” range compared to historic averages.

“Equity markets reached all-time highs midmonth and investors responded by increasing exposure to U.S. markets, ending the period as net buyers of equities,” said JJ Kinahan, chief market strategist at TD Ameritrade. “January ended with some uncertainty, so we’ll be watching closely to see how global health concerns over coronavirus impact the markets.”

In January, the S&P 500 crossed 3,300 for the first time, while the Dow Jones Industrial Average breached 29,000. Returns for the three major equity indices were mixed during the period; the S&P 500 and Dow were both down by less than one percent, while the Nasdaq Composite increased 1.6 percent. Gains early in the period were helped by the U.S. and China signing a deal to ease trade tensions and solid economic data. Volatility picked up as the coronavirus outbreak amplified as the World Health Organization declared it a global public health emergency.

Retail investors at TD Ameritrade net bought popular names during the January IMX period, including:

  • Microsoft Inc. (MSFT)
  • Apple Inc. (AAPL)
  • Boeing Co. (BA)
  • Advanced Micro Devices Inc. (AMD)

TD Ameritrade clients also used record highs to net sell some popular names, including:

  • Amazon Inc. (AMZN)
  • Netflix Inc. (NFLX)
  • Twitter Inc. (TWTR)
  • Intel Corp. (INTC)

Millennial Buys & Sells

In January, there were some key differences in the stocks TD Ameritrade’s millennial clients net bought when compared to the total population. Millennials net bought Exxon Mobil Corp. (XOM) and Uber Inc. (UBER).

When it came to net sold stocks, millennials differed from the total client population with Micron Technology Inc. (MU), Fitbit Inc. (FIT) and Tesla Inc. (TSLA).

About the IMX

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.
