Semiconductors & Electronics: Beta, Multiples & WACC by Sector

← Swipe left or right to move through the sections →

What the numbers say.

The semiconductor sector has shifted noticeably this month. It is valued notably lower than a month ago: the median EV/Sales fell to 3.5x and most companies became cheaper, the beta rose to 1.46, and the cost of capital stands at 12.0 %. Margins, not growth, separate the expensive companies from the cheap ones. The sector is calmer than in September: the choice of peers and settings moves the value less than it did.

EV/Sales is the multiple to use

It is the tightest of the multiples the fundamentals explain, a dispersion of 36 % across the 20 companies. EV/Sales spreads by 36 % because it carries the margin differences with it.

The beta to use: 5 years, monthly, 1.46

Among the stable settings it has the tightest spread across the 20 companies; R² 28 %, 18 of 20 betas significant, less liquid group (median bid-ask spread 0.37 %). It is the smartZebra standard setting. The settings alone move the median beta from 1.10 to 1.46.

The choice of peers matters

Ten of the twenty companies move the EV/Sales median by −13 % to +40 %, the settings by up to 31 %. Semiconductor sits in the peer-selection corner of the map.

Expected growth is confirmed

The usual yardsticks for semiconductor: gross margin and expected growth. Gross margin: partly (rank correlation +0.60 with EV/Sales (NTM)). Expected growth: confirmed (rank correlation +0.61 with EV/Sales (NTM)). Median EV/Sales (NTM) by sub-group: semiconductors & equipment 3.6x, electronics & instruments 3.5x.

EV/Sales (NTM): median 4.2x → 3.5x

Peer selection decides

Cost of capital

Cost of equity (CAPM)

“kE = rf + β · MRP”

rf = base rate, MRP = market risk premium, β = sector median beta.

WACC

“WACC = E/(D+E) · kE + D/(D+E) · kD · (1 − t)”

kD = base rate + credit spread; t = peer-average tax rate.

Tax rate

“t = average tax rate of the 20 peers”

Shown above as Tax rate (%).

Selection rules

Best-fit multiple

“lowest dispersion across the 20 companies”

The reference multiple is used only as a fallback.

Beta setting

“tightest spread among stable settings”

Replaces 5y monthly only if it passes the two-month rule.

Status

“|Δ value| ≤ 1 % and |Δ β| ≤ 0.03 → stable”

Up to ±5 % / ±0.06 → shifted a bit; beyond → shifted noticeably.

Scope

The 20 largest European listed companies by market value with core business in semiconductors, semiconductor equipment, electronic components and instruments; primary listing on a European exchange; banks, insurers, financial services and real estate are excluded.
