The reading for the four-week period ending June 25, 2021 ranks “High” compared to historic averages.

“The S&P 500 and Nasdaq achieved record highs amid generally positive economic data and cooling inflation fears, helping drive our Investor Movement Index to a new peak in June,” said JJ Kinahan, chief market strategist, TD Ameritrade. “We’re heading into what is usually the summer lull, with relatively light trading volumes and low volatility, but corporate earnings loom large in July. The guidance from big names, starting with Financials, will be a focal point, and depending on what is said, the markets as a whole are likely to move based on their outlooks for the rest of the year.”

Equity markets were mixed during the period. The Dow Jones Industrial Average moved lower, down 0.3% during the period. The S&P 500 and Nasdaq Composite both moved higher, reaching all-time highs in the process. The S&P 500 increased by 1.8%, with the Nasdaq up 4.5%. Economic news was generally positive, although retail sales fell by 1.3% as consumer spending shifted from goods to services. President Biden and a group of senators announced a $1 trillion bipartisan infrastructure agreement to overhaul transportation, water, and broadband capabilities. Federal Reserve officials signaled an earlier-than-expected interest rate increase as the economy recovers from the pandemic and inflation heats up, while investors generally continue to believe recent inflation will be transitory.
