Post No. 18. Black
Monday (1987)
Black Monday refers to Monday, October 19, 1987, when stock
markets around the World crashed, shedding a huge value in a very short time. The
crash began in Hong Kong and spread west to Europe, hitting the United States
after other markets had already declined by a significant margin. The Dow Jones
Industrial Average (DJIA) fell exactly 508 points to 1,738.74 (22.61%). IN Australia and New Zealand , the 1987 crash is also
referred to as “Black Tuesday” because of the time zone difference. The terms
Black Monday and Black Tuesday are also respectively applied to October 28 and
October 29, 1929, which occurred after Black Thursday on October 24, which
started the Stock Market Crash of 1929.
On October 14, the DJIA dropped 95.46 points (3.8%) (a then
record) to 2,412.70, and fell another 58 points (2.4%) the next day, down over
12% from the August 25 all-time high.
On October 15, 1987, Iran
hit the American-owned ( and Liberian-flagged) supertanker, the Sungari, with a
Silkworm missile off Kuwait ’s
main Mina Al Ahmadi oil port. The next morning, Iran
hit another ship, the U.S.-
flagged MV Sea Isle City, with another Silworm missile.
On October 16, when all the markets in London were
unexpectedly closed due to the Great Storm of 1987( a violent extratropical
cyclone that occurred on the night of 15-16 October, with hurricane- force
winds causing casualties in England, France and the Channel Islands. Among the
most damaged areas were Greater London, the East Anglian coast, the Home Counties,
the west of Brittany and the Cotentin Peninsula of Normandy), the DJIA fell
108.35 points (4.6%) to close at 2,246.74 on record volume. Then- Treasury
Security James Baker stated concerns about the falling prices.
The crash began in Far Eastern markets the morning of
October 19, but accelerated in London time- largely because London had closed
early on October 16 due to the storm- by 9:30 am the London FTSE100 had fallen
over 136 points. Later that morning, two U.S.
warships shelled an Iranian oil platform in the Persian Gulf in response to Iran ’s Silkworm missile attack on the Sea Isle
City .
By the end of October, stock markets had fallen in Hong Kong
(45.5%), Australia (41.8 %),
Spain (31%), the United Kingdom (26.4%), the United States (22.68%) and Canada (22.5%).
New Zealand ’s
market was hit especially hard, falling about 60% from its 1987 peak, and
taking several years to recover.
The Black Monday decline was-and currently remains- the
largest one-day percentage decline in the DJIA. (Saturday, December 12, 1914,
is sometimes erroneously cited as the largest one-day percentage decline of the
DJIA. In reality, the ostensible decline of 24.39% was created retroactively by
a redefinition of the DJIA in 1916.
Possible causes for the decline included program trading,
overvaluation, illiquidity and market psychology.
Program trading is a type of trading in securities, usually
consisting of baskets of fifteen stocks or more that are executed by a computer
program simultaneously based on predetermined conditions. Program trading is
often used by hedge funds and other institutional investors pursuing index
arbitrage or other arbitrage strategies.
Overvaluation is a situation in which a security has too
high a price. This means that the technical indicators on the security do not
justify its current price. (The Free Dictionary by Farlex)
On investment, market liquidity is a market’s ability to
purchase or sell an asset without causing drastic change in the asset’s price.
Market psychology is the overall feeling among market
participants that impels them to buy or sell. For this reason, an upward-or
bullish-trend is associated with feelings of positive expectations expressed by
optimism and hopefulness.
A popular explanation for the 1987 crash was selling by
program traders, most notable as a reaction to the computerized selling required
by portfolio insurance hedges. However, economist Dean Furbush points out that
the biggest price drops, occurred when trading volume was light. In program
trading, computers perform rapid stock executions based on external inputs,
such as the price of related securities.
Common strategies implemented by program trading involve an attempt to engage in arbitrage ( practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices) and portfolio insurance strategies ( portfolio insurance is a method of hedging a portfolio of stocks against the market risk by short selling stock index futures.).
As computer technology became more available, the use of program trading grew dramatically within Wall Street firms. After the crash, many blamed program trading, and that the crash was merely a return to normalcy return to the way of life before World War I). Either way, program trading ended up taking the majority of the blame in the public eye for the 1987 stock market crash. U.S. Congressman Edward J. Markey, who had been warning about the possibility of a crash, stated that “Program trading was the principal cause.”

After Black Monday, regulators overhauled trade-clearing
protocols to bring uniformity to all prominent market products. They also
developed new rules, known as “trading curbs” or colloquially as circuit
breakers, allowing exchanges to temporarily halt trading in instances of
exceptionally large price declines in some indexes; for instance, the DJIA.
