June 3 (Reuters) - A glitch at the New York Stock

Exchange (NYSE) triggered massive swings in the shares of

Berkshire Hathaway ( BRK/A ) and Barrick Gold, and

trading halts in dozens of other companies on Monday, before the

bourse fixed the problem.

The NYSE, owned by Intercontinental Exchange ( ICE ), by

late morning said a technical issue had been resolved and that

the impacted stocks had resumed trading.

It was the second stock market hiccup in less than a week

after a glitch last Thursday affected the dissemination of

real-time data for the S&P 500 and Dow Jones

indexes for over an hour.

The Consolidated Tape Association (CTA), responsible for

disseminating real-time trade data on stock exchanges, said

Monday's problem related to a new software release at one of its

data centers.

The CTA said it resolved the issue by switching to a

secondary data center running the previous version of the

software.

It provided a list of 40 securities that were subject to

trading pauses on CTA between 9:30 a.m. and 10:27 a.m. ET and

that were potentially impacted by the technical issue.

Some of the stocks halted on the NYSE showed unusual

outsized movements.

Berkshire Hathaway's ( BRK/A ) class A shares and Barrick Gold were

shown to be down 99.97% and 98.54%, respectively, due to the

technical issue, before those trades were corrected.

After trading resumed, Berkshire Hathaway ( BRK/A ) was down about

0.3% and Barrick Gold was up 0.6%, and investors said overall

sentiment was unaffected.

Berkshire and Barrick Gold did not respond to requests for

comment about Monday's technical problem.

The S&P 500 was last down 0.4%.

"I don't think the overall market is reacting," said Art

Hogan, chief market strategist at B. Riley Financial.

The NYSE and the CTA said the problem was related to limit

up-limit down bands meant to prevent extraordinary market

volatility and extreme price movements in individual stocks by

preventing trades outside of specific price ranges that are

updated throughout the trading day.

The price band for each security is set at a percentage

level above and below its average price in the preceding five

minutes.

The bands were developed as part of the response by

financial regulators and exchanges to the "flash crash" of 2010,

which briefly wiped out nearly $1 trillion in market

capitalization in a few minutes.

On May 6, 2010 when equities were recovering from the

financial crisis and in the early stages of what would become a

near 11-year bull market, the Dow Jones Industrial Average

tumbled almost 700 points in minutes.

Exchange outages, caused by software and hardware glitches,

cyberattacks, and even hungry squirrels, have roiled markets and

shaken investor confidence for decades, as trading has moved

from the floors and pits of bourses to electronic systems that

match trades at nearly the speed of light.

In February 2023, the NYSE said it would reimburse investors

for losses due to a glitch that caused widespread confusion and

resulted in thousands of trades being nullified.

The NYSE did not immediately respond to a request for

comment about whether it would reimburse investors potentially

affected by Monday's issue.
