2026 YTD performance is exceptional. From the 2025-12-31 close of $34.92 to the 2026-04-28 close of $59.49 is +$24.57 / +70.4% in roughly 4 months. The driver: Q4’25 print on 2026-02-11 (which delivered +400 bps non-IFRS GM YoY expansion + $500M buyback authorization) plus AI / photonics narrative momentum.

3. Major price phases — IPO to today

Phase 1: IPO honeymoon (Oct 2021 – Q1 2022)

IPO at $47/share on Oct 28, 2021
Q4’21 rally to $64.97 by year-end (+40% from IPO)
All-time high $78.94 reached 2022-03-25 — driven by post-IPO retail enthusiasm + supply-chain crisis premium (“we need our own foundries”)
ARK / thematic-fund inflows; CHIPS Act expectation pricing
TAM optimism driven by AI + auto secular themes

Phase 2: 2022 derate (Apr 2022 – Dec 2022)

Sustained derate from $79 → $54 over the year
Sector backdrop: rising rates + Fed tightening compressed semi multiples
Smart Mobile demand inflected weaker as 2H22 destocking began
2022-12-30 close: $53.89 (-32% from peak)

Phase 3: 2023 recovery (Jan 2023 – Dec 2023)

$54 → $60.60 by year-end (+12.5%)
Sector rotation back into semis + AI-narrative onset
GFS peripheral to the 2023 NVDA-led AI rally given no leading-edge exposure
Mubadala stable holding; no major secondary

Phase 4: 2024 trough year (Jan 2024 – Dec 2024)

May 2024 Mubadala secondary at ~$70/share (high in the $70 zone) → ~5 pp Mubadala selldown
Q4’24 $935M Malta impairment announced → sentiment damaged
2024 close: $42.91 (-29%)
Cycle-bottom mentality; Smart Mobile destocking peaked

Phase 5: 2025 capitulation + recovery (Jan 2025 – Dec 2025)

All-time low $30.37 reached 2025-04-08 — capitulation low coinciding with cycle-trough Q1’25 ~$1,585M revenue
Recovery through summer/autumn 2025 as Q2’25 + Q3’25 earnings showed margin recovery
2025-12-31 close: $34.92 (still -19% YoY)

Phase 6: 2026 breakout (Jan 2026 – present)

Q4’25 print 2026-02-11 delivered +400 bps non-IFRS GM YoY + first-ever buyback authorization
AI / photonics narrative inflection (LWLG Mar 2026 PDK release on Fotonix; Marvell custom-AI traction)
AMF Singapore acquisition closed Nov 2025 → consolidates SiPh foundry layer
2026 YTD: +70.4% — the breakout phase

4. Technical levels worth tracking

Level	Type	Notes
$78.94	ATH (Mar 2022)	Multi-year resistance; only crossed once in company history
$65.05	52w high (Mar 2026 ⚠)	Very recent, fresh resistance
$59.49	Spot	Current price
$54-55	Front-month options max-pain ($55) + late-2022 trough	Near-term key level
$45	Mid-2024 / mid-2025 base	Strong structural support
$40-42	Multi-year support; FY24 YE $42.91	If breached, opens path to ATL retest
$31.51	52w low	Multi-year support
$30.37	ATL (Apr 2025)	All-time low; capitulation

5. Volatility profile

GFS’s 1.5 beta is moderate for a US-listed semis name. The 52-week range of $31.51 to $65.05 represents a 2.06× peak-to-trough spread — typical for a mid-cap cyclical foundry. Realized 30-day annualized volatility (estimated from price_history.json) is approximately 40-50% ⚠.

Front-month ATM implied volatility per CBOE option chain (2026-04-29 fetch): ~88% (60-strike May’26 expiration). This is elevated relative to realized 30d vol, reflecting:

Q1’26 6-K reporting risk (expected May 2026)
Mubadala secondary supply overhang (F-3ASR shelf live)
ICFR remediation path uncertainty
LWLG PDK / Fotonix monetization narrative

Read. Options pricing implies ~40 percentage points of “event-risk premium” over recent realized volatility. This is a structural premium for a controlled-company small-float stock — not unusual.

6. Volume and float liquidity

Metric	Value
20-day avg volume	~3.5M shares ◐
20-day avg dollar volume	~$208M
Float	~83M (per `STOCK_PRICE_DATA.json`)
Float turnover (20-day avg vol / float)	~4.2%
Days-to-trade-float	~24 trading days

Float liquidity is moderate. A $33B-mkt-cap company with only ~83M float-eligible shares means each percentage-point share-price move requires ~830K shares of net buying / selling — well within the 3.5M average daily volume but enough to make momentum-driven moves significant. Mubadala’s 81% stake is the structural reason for the small float.

7. Sector / peer relative-performance context

GFS’s 2026 YTD +70% performance vs. comparable specialty foundries:

TSMC: +5-10% YTD ⚠
UMC: +15% YTD ⚠
SMIC: +25% YTD ⚠ (China-domestic-supply premium)
Tower Semiconductor: +30% YTD ⚠
GFS: +70% YTD — outperforming the cohort by 40-65 percentage points

The outperformance reflects:

Q4’25 margin-expansion print delivered above-cohort-best operational improvement
AI/photonics narrative has more leverage on GFS via Fotonix than on commodity-foundry peers
Buyback initiation signaled capital-return turn
Trough-to-peak compounding — GFS started 2026 from a lower base

8. Forward catalysts

Date / window	Catalyst	Likely market impact
~May 2026	Q1 2026 6-K release	First post-buyback execution disclosure; AMITC 35% credit cycle visibility
Mar–Aug 2026	Mubadala selldown via F-3ASR shelf	Supply-overhang risk; capping on rally
~Aug 2026	Q2 2026 6-K	Mid-year mix-shift validation
H2 2026	LWLG / Fotonix customer tape-outs	AI/photonics monetization milestones
H2 2026	CHIPS milestone disbursements	Cash + tax-credit visibility
Feb 2027	FY26 20-F + buyback renewal	First full year of buyback execution disclosure

9. Open items / backfill queue

Specific catalyst-to-price-spike attribution — for the 2022-2026 daily price moves, attribute >5% single-day moves to specific 6-K, news, or sector catalysts.
Volatility regime calibration — primary-source 30-day realized vol from daily-bar price history (vs. aggregator beta).
Mubadala secondary pricing history — confirm May 2024 follow-on actual pricing (was $70 the strike?).
Float reconciliation — STOCK_PRICE_DATA.json reports 83M float; reconcile against 555.8M outstanding minus 81% Mubadala = ~105M non-Mubadala-owned shares. Definitions of “float” vary across data providers.
