Proassurance Corp 已在 2026/6/26 下市;內部人最後一份 Form 4 在 2026/6/26 申報;2026 年第 1 季末有 222 家機構在 13F 申報持有,市值合計 $12.7 億;沒有大師持有。
四種放空資料,量的東西都不一樣:
- 空單餘額:某個結算日還沒回補的放空股數。FINRA 每月公布兩次,在結算日後約 8 個工作天。
- 每日放空量:每天在場外成交、申報給 FINRA 的放空股數。算的是成交,不是未平倉的部位;隔天公布。
- 交割失敗:到了交割日還沒交付的股數。SEC 每月公布兩次,晚約 2 週。
- 暗池(ATS)成交量:每週在另類交易系統與其他場外市場的成交量。FINRA 在那一週之後 2~4 週公布。

每日放空量
場外成交裡的放空量,不是空單餘額:每天申報給 FINRA 的場外成交中放空的股數,最近 30 個交易日。
放空量比例不能當成市場情緒:造市商為了接買單、避險本來就會放空,放空通常就佔場外成交量的一半上下。
