MILAN/LONDON (Reuters) -The London Stock Exchange said on Tuesday regular activity had resumed after a brief outage affected its trading and information system and disrupted small-cap stock trades, the second such incident in less than two months.
The FTSE small cap index was subject to a trading halt during the outage, affecting some 222 stocks, including Tullow Oil, CMC Markets and Marston’s.
“Impacted securities are now in regular trading,” LSEG said in a notice published on its website.
An LSEG spokesperson did not comment beyond the notice.
FTSE 100, FTSE 250 and International Order Book securities – shares listed in London by overseas companies – had continued to trade normally, the exchange said.
It is the second time LSEG has flagged a disruption to trading in smaller stocks on the London market in less than two months. On Oct. 19, an outage was caused by a technical problem, according to LSEG.
In 2019, the London Stock Exchange suffered an almost two-hour outage that hit FTSE 100 and midcap stocks, which LSEG said was caused by a “technical software issue”.
Thomson Reuters, which owns Reuters News, has been a shareholder in LSEG since 2021. LSEG also pays Reuters for news stories.
