The Friday before Easter is the only non-federal holiday among the exchange’s nine closed days. The New York Stock Exchange has been closed every Good Friday for more than 150 years, with the exception of 1898, 1906, and 1907.
Why? Several myths surrounding this market closure exist. The stories range of religious agreements, to historically low trade volume, to good old fashioned superstitions about bad luck. Whatever the reasons, the long-standing tradition remains.
The other eight stock market holidays in the U.S. are New Year’s Day, Martin Luther King Jr.’s birthday, Washington’s Birthday, Memorial Day, Independence Day, Labor Day, Thanksgiving and Christmas.
