Outages Halt Small-cap Trading

The London Stock Exchange (LSEG.L) experienced two temporary halts in trading small company shares, including those on the FTSE small cap index, due to outages. This disruption affected hundreds of stocks, including Tullow Oil (TLW.L), CMC Markets (CMCX.L), and Marston’s (MARS.L).

Multiple Disruptions in Recent Months

This recent incident marks the second time in less than two months that trading in small company shares has been disrupted on the London Stock Exchange. Earlier, on October 19, the LSEG reported similar disruptions due to a technical problem, affecting smaller stocks.

Previous Outage History

In 2019, the London Stock Exchange experienced an outage for nearly two hours, impacting both FTSE 100 and midcap stocks. The exchange attributed that disruption to a ‘technical software issue.’

LSEG and Reuters Connection

Thomson Reuters, a shareholder in LSEG since 2021, has been connected with the exchange. LSEG also purchases news stories from Reuters. Notably, shares in LSEG, which trade on the FTSE 100, declined by 0.7% during this recent trading disruption, while the blue-chip index experienced a 0.6% fall.
