Three letters that cost investors $440 million

Trivia of the Day

In 1988, a clerical error in an SEC filing caused which company's stock to plunge 31% in a single day, wiping out nearly half a billion dollars in market value?

1. Atlantic Richfield
2. Ashland Oil
3. American Airlines
4. Apple Computer

Answer: Ashland Oil — The typist entered earnings of 1¢ per share instead of $1.01—a decimal-point error that triggered automated sell programs across Wall Street, erasing $440 million in market capitalization before the mistake could be corrected three hours later. The incident forced the SEC to implement new review protocols for corporate filings, transforming a single keystroke into the most expensive typo in securities regulation history and foreshadowing the algorithmic fragility that would define modern markets.

Word of the Day

perfidy noun · PUR-fih-dee

Deliberate breach of faith or trust; treachery. From the Latin perfidus (faithless), itself from per- (through, to destruction) + fides (faith)—the word entered English financial vocabulary through medieval bankruptcy courts, where it described debtors who concealed assets while claiming insolvency.

“The board's perfidy was complete: while assuring shareholders of the company's health, executives had quietly sold their entire positions at peak prices, a betrayal that would later define the very contours of insider-trading law.”

Joke of the Day

Why did the momentum trader refuse to go to therapy?

He was afraid of reversals.

This Day in History

1944 — Delegates at Bretton Woods signed the final Articles of Agreement, creating the International Monetary Fund and the World Bank—institutions that would govern global finance for the next three decades. Meeting at a New Hampshire resort while war still raged in Europe and the Pacific, representatives from forty-four nations essentially reconstructed the architecture of international money, pegging currencies to the dollar and the dollar to gold at $35 per ounce. The system's collapse in 1971 would be as consequential as its creation: when Nixon closed the gold window, he ended not just Bretton Woods but four thousand years of commodity-backed currency, launching the experiment in pure fiat money we inhabit still.
