On Monday, a large number of shares of an exchange-traded fund (ETF) managed by ETF star Cathie Wood were sold. In particular, this fund sold nearly 34,000 shares of Tesla Inc. (NASDAQ: TSLA), despite the fact that the fund's price had increased by more than 1 percent on the day. It should be noted that the fund has experienced a significant decline over the past year.

The ARK Innovation ETF (NYSEARCA: ARKK) was responsible for the sale of 33,919 shares of Tesla. At Monday's closing price, the transaction would have been valued at approximately $34.2 million. Despite the fact that this represents a small portion of the total holdings, every little bit helps. In the last year, the fund has lost 17 percent of its value.
