Top 5 Weekly Gainers/Losers

Ford (F) — Top Gainer (~+15% this week)

Crushed Q3 estimates and rallied despite trimming FY outlook tied to a Novelis supplier fire; the beat and signs of supply recovery triggered a sharp rebound. YTD: ~+43% into Oct 24.

Albemarle (ALB) — Gainer (~+10% this week)

Lithium bellwether surged as investors broadened beyond AI mega-caps and rotated into materials; momentum built into Friday's strong session. YTD: ~+14% into Oct 24.

IBM (IBM) — Gainer (~+9% this week)

Beat-and-raise Q3 (revenue +9% YoY) and emphasized a ~$9.5B AI book of business; shares spiked late week. YTD: ~+38% into Oct 24.

Deckers Outdoor (DECK) — Loser (~-14% this week)

Plunged after a weaker FY sales outlook and tariff-driven demand concerns overshadowed an EPS beat. YTD: roughly -60% into Oct 24.

Newmont (NEM) — Loser (~-11% this week)

Despite an EPS beat on record gold prices, shares slid on softer free-cash-flow outlook and a sharp bullion pullback. YTD: ~+118%+ into Oct 24.
