单一股票ETF这个概念才出现一年多，现在已经很流行了，出现了一系列产品，比如：
-
Leveraged long single-stock ETFs target a multiple of their stock. For example, the AXS 2X NKE Bull Daily ETF (NKEL) aims for two times the daily return of Nike stock. So if Nike rises 2% on a given day, the ETF is supposed to rise 4%.
-
Short single-stock ETFs target the inverse of their stock. The Direxion Daily TSLA Bear 1X Shares ETF (TSLS), a short single-stock ETF, tracks the opposite of the daily return of Tesla. That means if Tesla stock falls 5% on a given day, the ETF should rise 5%.
-
Leveraged short single-stock ETFs target a negative multiple of their stock. One example, the AXS 2X PFE Bear Daily ETF (PFES), is designed to give two times the opposite of the daily return of Pfizer. So if Pfizer falls 4% over a day, the ETF should rise 8%.
-
Hedged single-stock ETFs target a limited version of their stock's daily gains and losses. The Innovator Hedged TSLA Strategy ETF (TSLH), for example, tries to deliver the daily return of Tesla but is capped at a maximum of 9.29% and a minimum of -10%.
