The reading for the five-week period ending April 29, 2022 ranks “Moderate” compared to historic averages.

“Demand for equities was light to start the month, but as the major indices continued their strong pullback below key support levels, we saw demand accelerate,” according to Shawn Cruz, head trading strategist, TD Ameritrade. “Ultimately, TD Ameritrade clients were net buyers in April despite a slightly decreased appetite for market exposure generally and light selling in the Consumer Staples, Materials, Healthcare and Utilities sectors.”

Plenty of catalysts sparked elevated market volatility in April, leading to an ugly finish to what was already a bad month for equities as the final 15 minutes of trading in the period saw a gap lower down to the 4,125 level for the S&P 500. Although earnings generally came in above consensus, disappointing results from some of the largest companies by weighting in the S&P 500 failed to give the market the shot of optimism it needed. Despite widespread concerns and negative headlines around input costs, particularly on the commodity front, Consumer Staples was the only sector to finish the month in positive territory. After a turbulent month in March, Treasury volatility fell after the Federal Reserve made their highly anticipated rate hike. However, this stability may have been misleading as interest rates were on the move, steadily climbing and pausing just below 3% on the key 10-year Treasury Yield.

In April, TD Ameritrade clients were net buyers of equities and strong buyers of fixed income instruments. Some of the popular equity names bought in April were:

  • Inc. (AMZN)
  • Alphabet Inc. (GOOG)
  • NVIDIA Corporation (NVDA)
  • Twitter Inc. (TWTR)
  • Ford Motor Company (F)

Names sold during the period included:

  • Chevron Corp (CVX)
  • Nucor Corp. (NUE)
  • United States Steel Corp. (X)
  • General Electric Company (GE)
  • American Airlines Group Inc. (AAL)

Millennial Buys & Sells

TD Ameritrade Millennial clients mirrored the overall client population in reducing exposure for the third straight month but ultimately net buying during the period. Both TD Ameritrade Millennial clients and the overall TD Ameritrade client population favored some high beta semiconductor names, such as NVIDIA Corp. (NVDA) and Advanced Micro Devices, Inc. (AMD). News of Tesla CEO Elon Musk’s purchase of Twitter Inc. (TWTR) led to a surge in activity in the name from both the Millennial and overall TD Ameritrade client populations. At a sector level, TD Ameritrade Millennial clients were net buyers in Communication Services, Consumer Discretionary, Financials, Information Technology, and Materials, all of which were lower on the month.

Of the most popular names net bought in April, Millennials differed from the general client population in buying Microsoft Corp. (MSFT). Of the most popular names net sold, Millennials stood apart in selling Nokia Corp. (NOK) and Crowdstrike Holdings Inc. (CRWD).

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.
