In embodied AI, Symbotic is one of few names with real revenue — a $22.7B backlog, warehouse automation ramping. But see the structure: ~84.5% of revenue is from Walmart. You're not buying "the warehouse automation sector" — you're buying Walmart's capex timetable. Single-customer 85% is extreme concentration; gross margin is a thin ~21% for a name priced like high-growth tech. Size it to its hidden risk, not its fame.

在"具身智能"里，Symbotic 常被当成少数"真有收入"的标的——$227亿合同 backlog、真在放量的仓储自动化。但看清它的收入结构：最新财报里来自沃尔玛的收入占比约 84.5%。你买的不是"仓储自动化这个赛道"，而是"沃尔玛未来几年在自动化上的资本开支时间表"。加上毛利只有约 21%（对一家按高成长科技定价的公司偏薄），集中度和毛利这两根刺决定了它该是小仓、逢错杀低吸，而不是随主题追高。
