As the US stock market approaches a critical geopolitical juncture, the trading focus of retail investors is undergoing a significant shift. On May 14, according to data from a flow-tracking desk and a latest report from JPMorgan, while continuing to favor semiconductor assets, retail capital is accelerating its outflow from the software sector and shifting heavily towards copper ETFs and heavily shorted "meme" stocks targeted by hedge funds.
Market caution is rising, with overall retail buying volume having fallen below the 12-month average. However, against this backdrop of cooling overall trading, copper assets have emerged as a standout. Driven by a combination of rebounding Chinese demand, AI-driven fundamentals, and Middle East sulfur supply risks, retail investors' single-day purchases of copper ETFs hit a recent high, triggering significant market volatility.
Simultaneously, the tug-of-war between retail investors and institutions over certain heavily shorted stocks is intensifying again. Retail investors are persistently buying stocks that are heavily promoted on social media and heavily shorted by hedge funds. This contrarian strategy has significantly boosted the short-term trading heat of these stocks and raised the potential for a short squeeze. Copper Assets Surge, Defensive Allocation Rises JPMorgan data shows that last week, net inflows from retail investors were $6.4 billion, slightly below the 12-month average of $6.6 billion, with investors continuing to prefer ETFs (net inflow of $5.5 billion) over single stocks. As trading volume in tech-related ETFs declined overall, capital attention notably pivoted towards the copper sector. Due to recovering Chinese demand, strong copper demand from the AI industry, and supply chain risks related to Middle East sulfur, retail investors quickly rallied around this theme. On Tuesday, retail investors' single-day purchases of the copper ETF (COPX) recorded an extreme value (+6.7 z-score), followed by rapid profit-taking on Wednesday (-3.4 z-score). Additionally, fixed-income multi-sector ETFs, dividend-style ETFs, and international equity ETFs (EAFE) also saw significant inflows from retail investors, indicating a rising demand for defensive positioning ahead of major geopolitical events. Targeting High-Short Stocks, Reigniting the "Meme" Stock Battle Beyond the tech focus, retail investors, fueled by social media, are regrouping around heavily shorted "meme" stocks, engaging in fierce competition with hedge funds. JPMorgan points out that retail investors are continuously buying stocks with high short interest. For example, after receiving approval from the Competition Commission of India for exclusive control in acquiring Kenvue Inc., KMB saw $5.4 million in net retail buying last week, while short interest in the stock has increased by 5% since January 2026. Similarly, KLAR, which announced the integration of flexible payment options into the Google Gemini app, attracted approximately $53 million in net retail buying despite its stock price falling about 50% year-to-date. Concurrently, its short interest soared from 9% to 17%. Furthermore, RIVN, which launched an AI voice assistant, also received continued buying from retail investors, with its current short interest standing high at 19%. This opposition between retail buying and institutional shorting is continuously accumulating potential short squeeze risks. Divergence Within the Tech Sector: Selling Software Giants, Betting on Semiconductors While retail investors search for new themes beyond tech stocks, a major capital rotation within the tech sector is also directly impacting the market. This month, retail investors broke from their previous pattern, beginning to significantly reduce their exposure to software stocks. Microsoft shifted from being the second-most bought stock in April to the second-most sold stock so far in May, with net selling reaching $117 million last week. In stark contrast, retail investors continued to increase their positions in the semiconductor sector. Semiconductor ETFs like SOXX and SMH saw sustained inflows, and buying interest in DRAM remained strong even after more than quadrupling last week. JPMorgan's crowding analysis shows that crowding in the semiconductor sector has reached a historical high of 99.3%, while crowding in the software sector is only 22.8%. Notably, short capital continues to gather in the software sector, with the squeeze risk indicator hitting an extreme value of 100%, while short interest in the semiconductor sector remains stable and at relatively low levels.
