How is the SIMO UQS Score Calculated?
The UQS (Unified Quality Score) for Silicon Motion Technology Corporation is calculated using a proprietary 6-pillar framework with 29 financial metrics. Each pillar evaluates a different dimension on a 0–100 scale, then combines into a single weighted score. Scoring thresholds are calibrated per sector. Momentum is an optional Pro toggle — without it, you get the 5-pillar / 25-metric core shown below.
Quality (25%) measures profitability and capital efficiency — ROIC, ROE, margins, GP/Assets, and FCF Yield.
Moat (25%) assesses Silicon Motion Technology Corporation's competitive advantages across switching costs, network effects, cost advantages, intangible assets, and ecosystem scale.
Growth (20%) tracks revenue trajectory and earnings momentum, combining historical results with analyst forward estimates.
Risk (15%) is inversely scored — lower leverage and strong balance sheet health result in higher scores.
Valuation (15%) measures whether Silicon Motion Technology Corporation is fairly priced using earnings yield, price-to-FCF, PEG ratio, and EV/EBITDA relative to sector peers.
Six investor-inspired presets are available, each with different pillar weights: Balanced, Buffett, Munger, Lynch, Cathie Wood, and Graham. The public score shown here uses the Balanced preset. Learn more in our FAQ.
