Castle Securities: Retail investors in the US stock market are buying on dips at a record pace. According to Golden Jubilee Data on June 30th, Castle Securities analyst Scott Rubner pointed out that since the beginning of this year, retail investors have been "buying at the bottom" at a record speed. According to data compiled by Rubner, on days when the S&P 500 index fell, retail investors' buying volume was almost 3.5 times the daily average level; 'Bargain buying' has become the preferred strategy for retail investors in the first half of 2026. This is the strongest bargain hunting behavior since the company began tracking such data in 2020, and its scale even exceeds the record set in 2021 when the trend of "meme stocks" (individual investors grouping stocks) was prevalent.
