Western Digital Corporation (WDC)

Bottom line
WDC is trading near its usual valuation, in the middle of its recent price range, and recent volume suggests money flowing out. 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 22× against the 60% earnings growth analysts expect (a forward PEG of 0.37, 12 estimates). Historically, paying less than 1× growth has been the cheaper side.
Quality check: only about 34% of reported earnings arrived as free cash over the last year — a gap that often traces to working capital absorbing cash.
Price zones — In the middle of its recent range (Yellow)
At $450.44, the stock sits between its recent support and resistance levels. Over the past year WDC has traded between $77.90 and $799.87; its historical support zone sits near $368.41 and resistance near $519.62. It is above one of its moving averages and below the other — a mixed trend picture.
52-week range $77.90–$799.87 · 50-day average $519.62 · 200-day average $368.41
Money flow — Money is flowing out (Red)
Recent trading in WDC shows more volume on falling days than rising days, a pattern often described as distribution. Volume on up days has been about 0.7× volume on down days over the last 30 sessions.

一句话结论
WDC 估值接近其惯常水平，处于近期价格区间的中部，近期成交量显示资金正在流出。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 22× 与分析师预计的 60% 盈利增速放在一起看（前瞻 PEG 为 0.37，来自 12 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 34% 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 — 处于近期区间的中部
目前价格为 $450.44，位于其近期的支撑位与阻力位之间。过去一年 WDC 的价格在 $77.90 到 $799.87 之间波动；其历史支撑区在 $368.41 附近，阻力区在 $519.62 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 — 资金正在流出
WDC 近期下跌日的成交量高于上涨日，这种形态常被称为派发。过去 30 个交易日，上涨日的成交量约为下跌日的 0.7×。
