Western Digital Corporation (WDC)
Technology · Computer Hardware · Data as of 2026-10-22
Bottom line
WDC is trading near its usual valuation, near its historical resistance zone, and recent volume shows no clear direction. The picture is mixed, so it may be worth watching rather than acting on. Past patterns are not a guarantee of future results.
Valuation — Cheap-looking, with quality flags (Yellow)
For a fast-growing company like WDC (revenue is growing about 36% a year), we weigh next year's expected P/E of 17× against the 63% earnings growth analysts expect, counting at most 30% a year because growth that fast rarely lasts (a forward PEG of 0.57, 13 estimates). Historically, paying less than 1× growth has been the cheaper side.
Quality check: only about 37% of reported earnings arrived as free cash over the last year — a gap that often traces to working capital absorbing cash.
Price zones — Near its historical resistance zone (Red)
At $354.19, the stock is close to the upper end of its recent range. Over the past year WDC has traded between $117.23 and $799.87; its historical support zone sits near $117.23 and resistance near $413.93. It is below both its 50- and 200-day averages, which has historically signalled a downtrend.
52-week range $117.23–$799.87 · 50-day average $435.87 · 200-day average $413.93
Money flow — No clear direction (Yellow)
Buying and selling volume in WDC have been fairly balanced recently, with no strong accumulation or distribution pattern. Volume on up days has been about 0.8× volume on down days over the last 30 sessions.
Dividends & company facts
WDC paid $0.55 a share in dividends over the past year — 0.16% of today's price — and raised it 2 times in the last five years. It returned more through buybacks: $2.5 billion in fiscal 2026, about 1.9% of its market value.

一句话结论
WDC 估值接近其惯常水平，接近其历史阻力区，近期成交量没有明确方向。整体情况好坏参半，也许更适合先观察，而不是急于行动。过去的形态并不能保证未来的结果。
估值 — 看似便宜，但有质量警示
对 WDC 这样的高增长公司（营收年增长约 36%），我们把它明年的预期市盈率 17× 与分析师预计的 63% 盈利增速放在一起看，但增速最多按每年 30% 计算，因为这么快的增长很少能持续（前瞻 PEG 为 0.57，来自 13 份预测）。从历史来看，付出低于 1 倍增长的价格属于较便宜的一侧。
质量核对：过去一年，报告利润中只有约 37% 转化为自由现金——这样的差距常常源于营运资金占用了现金。
价格区间 — 接近其历史阻力区
目前价格为 $354.19，接近其近期区间的上沿。过去一年 WDC 的价格在 $117.23 到 $799.87 之间波动；其历史支撑区在 $117.23 附近，阻力区在 $413.93 附近。它同时位于 50 日和 200 日均线下方，这在历史上通常对应下降趋势。
资金流向 — 方向不明确
WDC 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 0.8×。
股息与公司概况
WDC 过去一年每股派息 0.55 美元，相当于当前股价的 0.16%，过去五年上调过 2 次。它通过回购返还了更多：2026 财年回购 25.3亿美元，约占市值的 1.9%。
