Author: Henry Turner Updated: 09-24-2025 02:28 PM

Market Overview

The stock market experienced a downward trend recently, with the Dow Jones index falling significantly, leading to notable stock declines. This article captures the impacts on various major stocks.

Freeport-McMoRan Sees Sharp Decline

Shares of Freeport-McMoRan Inc. (NYSE: FCX) faced a steep drop of 16.4%, closing at $37.94. This decline followed the company's announcement regarding its third-quarter sales guidance.

Incident Update

Additionally, the company reported a tragic incident at the Grasberg Block Cave mine, where two team members were fatally injured, and five others remain unaccounted for. Such news has understandably shaken investor confidence.

Other Notable Stock Movements

Alongside Freeport-McMoRan, several other companies recorded significant stock losses on the same day:

Zhengye Biotechnology Holding Limited (NASDAQ: ZYBT) saw its shares decline by 28.2%, priced at $5.02.
YD Bio Ltd (NASDAQ: YDES) experienced a drop of 15%, settling at $17.91.
Harmony Biosciences Holdings, Inc (NASDAQ: HRMY) fell 14.6% to $27.36. The decline was attributed to their Phase 3 clinical trial of ZYN002 for Fragile X syndrome, which did not meet its primary endpoint due to a higher than expected placebo response. This setback led to a lowered price target from Needham from $48 to $41.
Cohu, Inc (NASDAQ: COHU) faced a 12.7% drop, with shares closing at $19.85. The decline correlates with the announcement of an offering of convertible senior notes.
Rigel Pharmaceuticals, Inc. (NASDAQ: RIGL) declined by 12.7%, sitting at $29.69.
BGM Group Ltd. (NYSE: BGM) fell 12.2%, reaching $10.31.
