Five Notable Stock Losers on October 5, 2026

• Five companies from several sectors recorded double-digit declines on October 5, 2026.

• Sphere Entertainment fell following a Craig-Hallum downgrade, while C.H. Robinson declined after announcing its acquisition of RXO.

• Velo3D, Boost Run and Capricor Therapeutics also closed sharply lower, although no clear company-specific catalyst was established for their declines.

Velo3D (NASDAQ: VELO) fell 14.4% to $9.57, with approximately 7.53 million shares traded. The available information does not identify a specific catalyst for the additive-manufacturing company’s decline.

Sphere Entertainment (NYSE: SPHR) dropped 13.6% to $110.80 after Craig-Hallum downgraded the stock to Hold from Buy and lowered its price target to $132 from $170.

Boost Run (NASDAQ: BRUN) declined 13.3% to $14.33. The company had previously announced its inclusion in the Russell 2000 and Russell 3000 indexes, but that September announcement does not explain the October 5 decline.

Capricor Therapeutics (NASDAQ: CAPR) fell 13.1% to $7.78. Although the company has reported encouraging data involving its experimental Duchenne muscular dystrophy therapy, deramiocel, no specific catalyst for the day’s selloff was established.

Robinson expects approximately $300 million in annual cost synergies within two years after closing and expects the transaction to increase adjusted earnings per share within nine months of completion.
