TD Ameritrade Investor Movement Index: IMX Rises Amidst Mixed Economic Data in August

Clients increased exposure for the first time since November 2021, buying all S&P 500 sectors except Energy and Utilities during the volatile trading period

The Investor Movement Index® (IMXSM) increased to 4.82 in August, up from 4.68 in July. 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 August 26, 2022 ranks “Moderate Low” compared to historic averages.

“In August, clients had a lot to digest, from macroeconomic catalysts to noteworthy earnings and finally to the remarks shared by Chairman Powell at the Jackson Hole symposium,” said Shawn Cruz, head trading strategist, TD Ameritrade. “In the face of mixed signals, optimism waxed and waned. But despite how the period ended, on a whole, TD Ameritrade clients increased exposure in August, leading to the first bump the IMX score has seen since November last year.”

The August IMX period was another period of elevated volatility. However, unlike in July, the volatility was not constrained to a tight range, with the month starting off with a strong move higher--at one point trading up nearly +5%--before turning lower in the latter half of the month. As the rally off June lows carried over from July to August, economic data came in mixed; a strong beat on the Employment Situation report was followed by softer-than-expected Consumer Price Index (CPI) and Producer Price Index (PPI) data. These reports, combined with consumer sentiment data, led some investors to feel optimistic about the Federal Reserve’s progress in bringing down inflation and the possibility of having hit an inflection point in the battle against rising prices.

The falling inflation data did not translate to lower interest rates, though. The 10-year Treasury yield began August at levels not seen since April of this year but climbed higher throughout the month, breaking above 3% at the same time equities turned around and began their move lower. A major change in sentiment came mid-month with the release of Federal Reserve Federal Open Market Committee (FOMC) meeting minutes and various members of the Federal Reserve reiterating their commitment to aggressive Monetary Policy tightening. The final blow came at the end of the month as Federal Reserve Chairman Jerome Powell, speaking at the global central bank economic symposium in Jackson Hole, Wyo., acknowledged the likelihood of negative impacts to the economy in order to achieve lower inflation levels, dashing hopes of a policy reversal from the markets and driving significant risk-off behavior.

The increased exposure reflected in August’s IMX score was accompanied by strong buying from TD Ameritrade clients. Some of the popular equity names bought during the period were:

  • Amazon Inc. (AMZN)
  • Shopify Inc. (SHOP)
  • NVIDIA Corp. (NVDA)
  • Lucid Group Inc. (LCID)
  • AT&T Inc. (T)

Names sold during the period included:

  • Apple Inc. (AAPL)
  • Twitter Inc. (TWTR)
  • Netflix Inc. (NFLX)
  • Exxon Mobil Corp. (XOM)
  • Qualcomm Inc. (QCOM)

Millennial Buys & Sells

TD Ameritrade millennial clients increased exposure during the August period and were net buyers of equities overall, mirroring the overall TD Ameritrade client population.

Both TD Ameritrade millennial clients and the overall TD Ameritrade client population favored Google (GOOG/GOOGL) once again, with both populations net buying the Information technology giant. Amazon (AMZN) was another name both populations favored as the Consumer Discretionary giant broke out of a previous resistance level on the upside. Millennial clients were buyers of semiconductor giant Nvidia (NVDA) despite pessimistic forward guidance, and electric vehicle makers were also popular, with Tesla (TSLA), Rivian (RIVN), and Lucid Motors (LCID) net bought over the August period. In the Financial sector, JP Morgan (JPM) continued to trade near its lows for the year, and millennials differed from the overall population in net buying the Diversified Financials giant.

Similar to the overall population, millennials sold popular tech names like Apple (AAPL), Twitter (TWTR), Netflix (NFLX), and Roblox (RBLX). Airlines were also popular sells, including Delta Airlines (DAL), American Airlines (AAL), and Spirit Airlines (SAVE). Millennial clients were also net sellers of Boeing after the industrial giant rallied off of its June lows before turning lower in the August period.

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.
