An 83 percent plunge in storied Singapore-listed stock Jardine Matheson Holdings Ltd. Thursday has traders pointing to the most likely culprit: a fat finger.

Shares of the 186-year-old conglomerate plummeted in pre-market trading before bouncing right back to eventually trade higher as the session progressed. A spokesperson for the firm said it was aware an electronic trading error had occurred, while Singapore Exchange Ltd. said the bourse is looking into the stock slide.
