According to Eric Balchunas, ETF issuers specializing in high-risk investments, such as ARK, ProShares, and Direxion, were hit the hardest asset-wise by the market drop this year. In contrast, those focusing on buffer/cash strategies held up best, as reported by @psarofagis.

According to @psarofagis, ETF issuers like VanEck, Invesco, and Fidelity have significant exposure to the tech sector and could be most impacted if there's a market rotation away from tech. Conversely, FlexShares, DFA, and Avantis have less exposure due to their value tilts, thereby potentially mitigating risks in such a scenario.
