A media empire built on one name: Martha Stewart's conviction cost its stock 23% in a day

Martha Stewart Living Omnimedia went public in October 1999 and at its peak was worth about $2 billion. Its product was Martha Stewart herself: the magazine, the television shows, the Kmart home line and the catalogue all carried her name and her face, and the share price moved with her public image. The whole company was a bet on one person's reputation.

The bet broke in 2002. In December 2001 Stewart sold her ImClone stake — 3,928 shares worth about $230,000 — a day before the FDA rejected the cancer-drug application, and the SEC later charged that she sold on an illegal tip and then concealed facts and invented an alibi during the probes. On 4 June 2003 a federal grand jury indicted her on nine counts — obstruction of justice, making false statements and securities fraud — and the SEC filed its civil case the same day. She resigned as chairman and chief executive within hours, keeping only the title of chief creative officer.

The market priced the whole affair in one session. On 5 March 2004, as the jury deliberated, shares were up nearly 20% — investors expected an acquittal. When the verdict came in, guilty on all four counts, trading was halted, and by the close the stock was down 23%, to $10.86. The judge had already thrown out the securities fraud charge, but the verdict on obstruction and false statements was enough: the company's value was her credibility.

Stewart was sentenced on 16 July 2004 to five months in prison, five months of home confinement and two years of probation — light enough that the stock jumped about 35% that afternoon. The relief did not rebuild the company. Eleven years later, in June 2015, Sequential Brands bought Martha Stewart Living Omnimedia for $6.15 a share, about $353 million in total — a deal priced below the previous close, and a fraction of the $2 billion the company had been worth as a bet on one name.
