Why did Athira's other items fluctuate sharply?

The stock price of ATRA has experienced a significant decrease on April 10. According to the information I have found, there is no obvious negative news for ATRA. Therefore, the sharp decrease might be related to the market situation. From April 3 to April 9, the S&P 500 lost 10.5% of its value, which is its fifth-biggest two-day downdraft in 75 years. The Dow Jones Industrial Average, S&P 500, and Nasdaq Composite have been whipsawed over the last week, and the volatility has been further intensified by the uncertainty around the tariff policies in the U.S. The severity of the sell-off is creating opportunities, and the probability of a rally has increased, according to UBS. Therefore, the sharp decrease of ATRA might be related to the market situation and the uncertainty around the tariff policies.
