More than half a century ago, Polaroid Corp. dominated the instant‑camera market, controlling nearly two‑thirds of global sales and trading at earnings multiples exceeding 90× before the Nifty Fifty bubble burst.

John Authers, Bloomberg Opinion columnist and former chief markets commentator at the Financial Times, reminds readers that the extreme valuations of the 1980s were a product of that era’s exuberance. He draws a parallel to the current AI‑driven rally, noting that the lofty multiples enjoyed by the Nifties were far beyond what is typical today.

While the technology landscape has shifted dramatically, the cautionary tale of Polaroid’s collapse still echoes. Authers’ analysis underscores the risk of chasing high valuations without solid fundamentals—a lesson that remains relevant as investors weigh the prospects of emerging tech sectors.

The article, published on May 14, 2026, serves as a timely reminder that market euphoria can be short‑lived, and that historical precedents like Polaroid’s meteoric rise and fall should inform modern investment decisions.
