Trading halted temporarily twice on the FTSE Small Cap index
Trading was temporarily halted twice on the FTSE Small Cap index, affecting hundreds of stocks including Tullow Oil (TLW.L), CMC Markets (CMCX.L), and Marston’s (MARS.L).
Investigation into the incident
LSEG stated in a notice published on its website at 11:23 AM GMT, about an hour after the previous interruption was resolved, that it is still investigating the matter. It added at 12:43 PM GMT: “The affected securities are now trading normally.”
Impact of the interruption on other markets
The FTSE 100 (.FTSE), FTSE 250 (.FTMC), and securities listed on the international order book – stocks listed in London by foreign companies – continued to trade normally, according to the exchange.
Previous impact of disruptions
In 2019, the exchange experienced a trading interruption that lasted nearly two hours, affecting the FTSE 100 index and mid-cap stocks, with LSEG reporting that the cause was a “technical software issue.”

LSEG shares, traded on the FTSE 100 index, fell 0.7% in the latest trading, compared to a 0.6% drop in the main index.
