August 11th – This Day in Stock Market History

August 11, 1982 – Bell System Antitrust Breakup Approved

On this day in 1982, a landmark antitrust action reshaped the U.S. telecommunications industry. Federal Judge Harold Greene issued a 178-page opinion approving the settlement to break up the Bell System monopoly (AT&T).

This divestiture split AT&T into seven “Baby Bell” regional carriers on January 1st, 1984 and left AT&T as a long-distance provider.

The immediate market impact was significant – investors had to assess the values of the new regional telecom stocks and AT&T’s refocused business.

The breakup also created a significant arbitrage opportunity that lead to, at the time, the largest single trade in history placed at the NYSE. In 1983, Ed Thorp bought $330 million worth of the old AT&T stock while simultaneously shorting $332.5 million of the “when-issued” shares (a bundle that represented ten shares of the new AT&T plus one share in each of the seven Baby Bells). The difference between the two positions was a razor-thin 0.76%, but that sliver of arbitrage translated into $2.5 million in profits for Thorp’s hedge fund.

In the long run, the breakup ushered in greater competition and innovation: consumers soon benefited from a proliferation of new telephone equipment and competitive long-distance options as rivals like MCI and Sprint gained ground.

The remaining AT&T company stock averaged a 9.4% annual return for the next 42 years:

The ruling also nearly exactly coincided with the bottom of the 1966-1982 bear market. Despite the headwinds of losing a monopoly, the remainder of AT&T flourished and performed very well for investors that held.

August 11, 1987 – Alan Greenspan Takes Office as Fed Chair

Alan Greenspan was sworn in as Chairman of the Federal Reserve on this day in 1987.

U.S. stocks would hit record highs within weeks of Greenspan taking the helm. But the fun would not last long for Greenspan. Just 69 days later, the infamous Black Monday crash on October 19, 1987 would occur, providing Greenspan with his first test as Fed chair. The new Fed Chair’s response – pledging liquidity and cutting interest rates – was credited with calming the panic. Markets recovered to finish 1987 slightly up for the year.

Greenspan would also become infamous due to his actions during the tech bubble in the late 1990s and early 2000s. While obviously not the sole cause, Greenspan has faced criticism for being too lax with monetary policy as asset prices inflated during the tech bubble.

Greenspan’s tendency to lower interest rates when the market faltered led to the perception that the Fed would always step in to support asset prices, creating a “Greenspan put”. This encouraged investors to take on more risk, believing the Fed would protect them from losses.
