Semiconductors — Historical Charts and Data
Every Semiconductors chart, valuation metric, drawdown record, and constituent breakdown from History of Market. 12 panels, refreshed daily.
§ I
PHLX SOX · 1994 to present — Three decades of the Philadelphia Semiconductor Index
Daily closes since May 1994, with the drawdown ribbon beneath. The chart spans two crashes (2000, 2008), two mid-cycle drawdowns (2018, 2022) and the AI-era bull — the highest-amplitude industry in U.S. equities on a single canvas.
PHLX SOX · Annual Return — The semi sector's year-by-year ledger
Year-end print for every year since 1995. Average return runs well above the S&P, but every few years a near-halving year prints — 'high mean ≠ steady growth' is most extreme here.
PHLX SOX · Return Distribution — Thirty years of annual returns, binned
Every year placed into one of 11 buckets. The right tail past +50% is populated more than once; the left tail past -40% is too. This is the fat-tailed shape of semis, not a tidy bell curve.
§ II
§ III
PHLX SOX · 30 components — What's actually inside SOX
Thirty names grouped by sub-industry: fabless logic, foundry, memory, equipment, analog, RF, and the lone IDM. Foreign names are flagged by country code — semis are not a purely American sector.
SMH · VanEck Semiconductor — What SMH actually owns, and at what weight
SMH tracks the MVIS US 25 Index — 25 names total. Yahoo exposes live weights for the top ~10 (about 70% of the ETF); the remaining 15 are listed with sub-sector tags but marked 'n/a' on weight.
Memory · DRAM / NAND / HBM — The cycle king — and only one of them survives in SOX
Memory is the highest-amplitude semi sub-industry. MU is the only pure-play in SOX; Samsung and SK Hynix trade on KOSPI. Buying SMH leaves you ~60% short of global memory market cap. The AI HBM boom is split among these three.
SOXX · iShares Semiconductor ETF — SOXX at the wrapper layer
SOXX tracks the ICE Semiconductor Sector Index (formerly PHLX SOX): 30 components, 8% single-stock cap, rebalanced quarterly. This panel deliberately stays in the package layer — AUM, expense ratio, top-10 concentration ladder, country and sub-sector breakdowns. The 30-name constituent map already lives on the preceding 'Inside the Index' panel and isn't repeated here.
SOXX vs SMH · metadata, overlap, ten-year return — SOXX and SMH — same label, different weighting paths
Both are 'semiconductor ETFs' but the curves have diverged. SMH carries 25 names with a 20% single-stock cap (TSM and NVDA sit at the very top of the ladder); SOXX carries 30 names with an 8% cap and is materially more balanced. 22 names sit in both ETFs; SOXX adds 8 smaller / specialty names, SMH adds 3 foreign names (ASE, STM, UMC) that SOXX doesn't carry. Over ten years SMH compounds to ~24×, SOXX to ~20× — the 2023-2024 AI rally fed the concentrated top of SMH's ladder more than SOXX's flatter cap.
§ IV
SOX / SPX · SOX / XLK · XLK / SPX — Who's leading, who's lagging
Three rebased ratios, indexed to 100 at year-end 1999. Semis vs the broad market, semis vs the broader tech sector, and tech vs the broad market. Click any legend entry to toggle a line; zoom in to read each leadership regime.
Memory Cohort · TTM PE vs 1999 — How far are memory & HBM from 1999
MU and NVDA's TTM PE from 2022 to today, with horizontal reference bands marking the 1999-2000 dotcom-peak forward PE prints (CSCO 140×, ORCL 150×). The cards below add today's snapshot for Samsung and SK Hynix — the true HBM protagonists — but their reporting cadence and accounting basis differ, so they appear as today's numbers only.
