Helios and Matheson Analytics Inc , saw trading paused under the "Limit Up/Limit Down" program launched by exchanges in order to address market volatility and consists of a gradually expanding list of stocks for inclusion.

Limit Up/Limit Down halts are triggered when trading in a stock moves outside of a shifting price band, a range which is based on recent prices, for more than 15 seconds. Helios was added to the program on Monday.

Each of the four stocks has market capitalizations of less than $30 million.

Nasdaq was not immediately available for comment.
