Healthcare · Medical - Instruments & Supplies · Data as of 2026-09-01
Bottom line
WST is trading at a premium to its history, near its historical resistance zone, and recent volume shows no clear direction. Historically, this combination has called for extra caution. Past patterns are not a guarantee of future results.
Valuation — Trading at a premium (Red)
WST trades at 43× earnings, roughly in line with its own 5-year average of 46× and above similar healthcare companies we track (29×, 52 peers). Investors are currently paying more per dollar of earnings than usual. Its free-cash-flow yield is about 1.8%. Its current multiple sits around the 48th percentile of its own last five years — around the middle of its own range. About 79% of its reported earnings arrived as free cash over the last year.
Price zones — Near its historical resistance zone (Red)
At $338.65, the stock is close to the upper end of its recent range. Over the past year WST has traded between $223.83 and $386.00; its historical support zone sits near $292.55 and resistance near $350.08. It is above one of its moving averages and below the other — a mixed trend picture.
52-week range $223.83–$386.00 · 50-day average $350.08 · 200-day average $292.55
Money flow — No clear direction (Yellow)

一句话结论
WST 相对自身历史处于溢价水平，接近其历史阻力区，近期成交量没有明确方向。从历史来看，这样的组合需要格外谨慎。过去的形态并不能保证未来的结果。
估值 — 相对自身历史处于溢价水平
WST 目前的市盈率为 43×，大致持平于其自身 5 年平均的 46×，并且高于我们追踪的同类Healthcare公司（29×，52 家）。投资者目前为每一美元盈利付出的价格高于以往。其自由现金流收益率约为 1.8%。它当前的估值倍数大约位于自身过去五年分布的第 48 百分位——处于自身区间的中部。过去一年，其报告利润中约有 79% 转化为自由现金。
价格区间 — 接近其历史阻力区
目前价格为 $338.65，接近其近期区间的上沿。过去一年 WST 的价格在 $223.83 到 $386.00 之间波动；其历史支撑区在 $292.55 附近，阻力区在 $350.08 附近。它位于其中一条均线上方、另一条下方——趋势信号并不一致。
资金流向 — 方向不明确
WST 近期的买卖成交量大致均衡，没有明显的吸筹或派发形态。过去 30 个交易日，上涨日的成交量约为下跌日的 1.2×。
