Bottom line
PSA is trading at a premium to its history, near its historical support zone, 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 — Above its usual book-value multiple (Red)
For financial companies we look at price versus book value. PSA trades at 6.0× book value, against its own typical 5.1× while earning a 22% return on equity. Its current multiple sits around the 65th percentile of its own last five years — toward the high end of its own range.
Price zones — Near its historical support zone (Green)
At $302.86, the stock is close to the lower end of its recent range. Over the past year PSA has traded between $256.54 and $335.55; its historical support zone sits near $297.30 and resistance near $321.45. It is above one of its moving averages and below the other — a mixed trend picture.
52-week range $256.54–$335.55 · 50-day average $321.45 · 200-day average $297.30
Money flow — Money is flowing out (Red)
Recent trading in PSA shows more volume on falling days than rising days, a pattern often described as distribution. Volume on up days has been about 1.0× volume on down days over the last 30 sessions.

一句话结论
PSA 相对自身历史处于溢价水平，接近其历史支撑区，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 — 高于其惯常的市净率水平
对金融公司，我们看的是价格与账面价值的关系。PSA 的市净率为 6.0×，而它自身惯常的水平是 5.1×，同时取得 22% 的净资产收益率。它当前的估值倍数大约位于自身过去五年分布的第 65 百分位——处于自身区间的偏高位置。
价格区间 — 接近其历史支撑区
目前价格为 $302.86，接近其近期区间的下沿。过去一年 PSA 的价格在 $256.54 到 $335.55 之间波动；其历史支撑区在 $297.30 附近，阻力区在 $321.45 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
PSA 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 1.0×。
