Retail investors have driven a record inflow into the Direxion Daily Tesla Bull 2X Shares ETF (TSLL), a leveraged fund designed to deliver twice the daily return of Tesla Inc. (TSLA). Last week saw approximately $651 million poured into TSLL, marking the largest weekly inflow since the fund's inception in 2022. Friday alone recorded the biggest single-day inflow for TSLL, with estimates ranging from $500 million to $600 million. This surge in investment highlights a strong retail appetite for leveraged exposure to Tesla shares, contributing to one of the highest notional volume days for single-stock ETFs since their introduction in 2022. Market observers note that the growing size of TSLL inflows may increase Tesla's stock volatility due to the leveraged nature of the ETF.
