It has AUM of $2.91 billion and charges adjusted expense ratio of 23 basis points.Why the Move?Wall Street is mostly seeing a rough stretch marked by the sharp sell-off in technology stocks beginning Sep 3. The market turbulence could have been a result of people rushing to book profits, probably due to worries over high valuations, uncertainty over another pandemic stimulus-relief package, budget negotiations and the approaching elections. Also, September is historically considered the worst month for the stock market. Per LPL Financial data in a Yahoo Finance article, the S&P 500 has fallen about 1%, on average, in September since 1950.
