NYSE Arca, the New York Stock Exchange’s sister market, widened the amount prices are able to move when a security reopens after a trading halt.

Under the exchange’s new rule, securities valued at 1 cent to $25 a share can rise or fall 10 percent from their prior level. Securities between $25.01 and $50 can move 5 percent, and those valued at more than $50 can move 3 percent. Previously, those thresholds were 5 percent, 2 percent and 1 percent, respectively.
