ProShares

ProShares 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 issuer the episode associates with the 2006 U.S. leveraged ETF rollout. The source uses that launch to place modern products such as TQQQ inside a longer sequence of retail-accessible daily leverage.

The wiki role is historical rather than evaluative. ProShares helps distinguish the ETF implementation route from Chinese [[ChineseStructuredFund|structured funds]] and ETN-style financing products such as FNGU.
