Fair Isaac Corporation (FICO) closed at $931.87 on September 5, 2026, after shedding 16.72% in a single trading session. The steep one-day decline pushed the stock's market capitalization to $24.17 billion.
The session's drop extended an already difficult stretch for the analytics and credit-scoring company. Over the past seven days, FICO shares have fallen 19.15%, and the 30-day loss now stands at 9.95%, reflecting sustained selling pressure across multiple timeframes.
The back-to-back declines mark one of the more severe short-term drawdowns in the stock's recent history. The seven-day loss of 19.15% encompasses and amplifies the 30-day trend, suggesting the bulk of recent selling concentrated in the final week of that period.
No single catalyst is identified in the available data, but the breadth and speed of the decline across the 24-hour, seven-day, and 30-day windows underscore the magnitude of the move in FICO shares heading into the close of the session.
