Some stock values are affected by a technical issue on the NYSE, which incorrectly displays Berkshire Hathaway as down 99%.

Nearly 100% of Warren Buffett's A-class shares at the New York Stock Exchange experienced a technical issue on Monday, causing them to appear to be down.

Those shares, as well as and , experienced dramatic falls and trading was halted.

The NYSE is currently investigating a technical problem concerning the limit up and limit down bands, which are used to halt stocks when they experience excessive volatility. The extent of the issue's impact on stocks is unknown.

On Monday morning, Berkshire's B-class shares were down less than 1% while trading in A-class shares was halted with fewer than 4,000 recorded trades.

The major market averages remained unchanged despite the executed maneuvers.

Berkshire's original Class A shares are among the most expensive shares on Wall Street. Last week, each share sold for about 45% more than the median price of a home in the U.S. On March 28, Berkshire's Class A shares hit an all-time closing high of $634,440.

Buffett has never split the stock because he wants to attract long-term investment-oriented shareholders. Graham, Buffett's protege, stated that many Berkshire shareholders use their stock as a savings account.

In 1996, Berkshire Hathaway issued Class B shares at a price of one thirtieth of a Class A share to accommodate smaller investors seeking a smaller stake in the company's performance.

Since 1965, Buffett has been the CEO of Berkshire, and as of now, he owns more than 38% of class A shares, according to FactSet. Buffett has pledged to donate his fortune, which he built at Berkshire, to charitable causes.
