TQQQ

TQQQ appears in vol.121.从昙花一现的分级基金到风头正劲的杠杆ETF：永远不要低估人性的疯狂 as the canonical three-times technology-index leveraged ETF example. The episode uses TQQQ’s product-disclosure style to explain why a fund that targets daily multiples can perform very differently from three times the underlying index’s long-period return.

The source uses TQQQ to make [[VolatilityDecay|volatility decay]] concrete: large up-and-down moves can reduce the leveraged fund’s NAV even when the underlying index is near flat. That makes TQQQ a tool for tactical exposure rather than a default replacement for [[PassiveInvesting|passive index investing]].
