Moat scores for companies ranked near SIMO in Semiconductors
Pricing power is the ability to raise prices without losing volume.
Cost Advantage
Score 71
· 15% of the moat score
A cost advantage means delivering the same product for structurally less — better purchasing, denser distribution, a more automated process.
Customer Stickiness
Score 38
· 15% of the moat score
Stickiness is what makes revenue repeat without being re-won every year.
Capital Efficiency
Score 81
· 18% of the moat score
Capital efficiency asks what the company earns on the money tied up in the business.
Resilience
Score 66
· 17% of the moat score
Resilience is the capacity to get through a bad year on its own terms — enough liquidity, enough interest cover, and enough cash generation to avoid a rescue financing or a forced sale.
Scale & Market Position
Score 52
· 15% of the moat score
Scale matters only when it converts into economics.
What is Silicon Motion Technology Corpo's moat score?
Silicon Motion Technology Corpo (SIMO) scores 63 out of 100 on the StatsAlpha Moat Map, which rates its competitive advantage as moderate. It ranks #18 of 66 scored companies in Semiconductors, the top 27%. The score is a weighted composite of 6 competitive defenses, each measured against industry peers of 65 companies in Semiconductors. Its strongest defense is Capital Efficiency (81/100) and its weakest is Customer Stickiness (38/100).
How does Silicon Motion Technology Corpo compare with other Semiconductors companies?
Silicon Motion Technology Corpo ranks #18 of 66 scored companies in Semiconductors by moat score. The widest moat in Semiconductors is NVE Corporation (NVEC) at 86/100. The companies ranked closest are Tower Semiconductor Ltd. (TSEM) at 63 just above it and Marvell Technology, Inc. (MRVL) at 62 just below it.
How is the moat score calculated?
Each company is scored with an industry-specific template — Corporate Default in this case, chosen because the defenses that matter to a bank are not the ones that matter to a software company. Every defense combines several financial signals, and each signal is measured as a percentile against a peer group of 65 companies in Semiconductors. The defenses are then weighted to produce the overall score out of 100.
Why is Silicon Motion Technology Corpo scored with the Corporate Default template?
Most public companies sell a product or a service at a margin, so the moat question is whether that margin survives contact with competitors. The Corporate template scores the six defenses that show up in a general operating company's financial signature: whether it can hold price, produce more cheaply than rivals, keep its customers, earn a return above its cost of capital, withstand a downturn, and turn size into economics.
Which competitive defenses are measured for Silicon Motion Technology Corpo?
The Corporate Default template measures 6 defenses, and SIMO scores: Pricing Power (65), Cost Advantage (71), Customer Stickiness (38), Capital Efficiency (81), Resilience (66), Scale & Market Position (52). Each is scored independently as a percentile against peers, so a company can be strong on one and weak on another — the overall score reflects how those defenses are weighted for this industry.
