How is the moat score calculated?
Each company is scored with an industry-specific template — Bank Specialized 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 399 companies in Banks - Regional. The defenses are then weighted to produce the overall score out of 100.
Why is Westamerica Bancorporation scored with the Bank Specialized template?
A bank does not sell a product at a margin. It funds itself, lends at a spread, and books profits that remain an estimate until the loans are actually repaid. That makes the usual margin-and-return questions misleading, so the Bank template scores what really determines a bank's durability: where its funding comes from, what it lends against, how much capital stands behind it, and whether it has been pricing risk honestly.
Which competitive defenses are measured for Westamerica Bancorporation?
The Bank Specialized template measures 6 defenses, and WABC scores: Deposit Franchise (61), Lending Advantage (86), Capital Strength (89), Cost Discipline (94), Revenue Diversification (25), Risk Management (70). 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.
