About twice QQQ’s yearly return, with three times its volatility. The table uses daily closes from the Jun 30, 2016 close, with dividends reinvested.
TQQQ’s total return over the window was 4,140.8%, against 2,073.9% for the 2× fund QLD and 637.3% for QQQ. Its volatility, 66.1% a year, was about three times QQQ’s 22.3%: the risk scaled fully, the return did not. Our guide to whether leveraged ETFs improve returns uses month‑end data over the 10 years to Sep 2026, which gives 41.4% a year and a 79% worst fall; the window and data differ, the picture is the same.
The decade was kind to leverage. The Nasdaq‑100 rose strongly and recovered quickly from each fall. TQQQ launched in February 2010, according to ProShares, so it has never been through a 2008‑style crisis. In the 2007–09 crisis the 2× Nasdaq‑100 fund QLD, which did exist, fell 84.1%.
