新手看價 老手看量
既然已在市場八年 年齡不大
不敢說是高手 也得說是老手
那就 來聊一些量的東西吧!
量和籌碼有關 這裡想跟大家聊聊"周轉率"
周轉率的計算方式為:今日成交量/總股票發行量
周轉率代表的的意義是"今天有百分之多少的股東換人"
所以我們要先知道 到底這家公司發行了多少股票呢?
目前台股公司幾乎都是面額10元發行
[現在已經開放不是10元的公司掛牌 所以往後要留意]
只要查出公司的股本即可
例如某家公司的股本為8E 以面額10元計算
這家公司發行的股票數量即為8萬張
今天的成交量簡單查報價系統就有了
強勢股的末升段多半是爆量煙火做結束
所以周轉率有助於我們評估
是否這檔個股的交易量已太過於火爆
在我認為 運用這個指標上還要多考慮兩個變數:
1. 用股本來計算發行量是OK
但發行量並不代表都會在外面流通
例如 股本30E的裕日車(2014.1.22資料)
總股票發行量為30萬張 沒問題
不過看到董監持股部份 兩大股東(裕隆和日產)就持有了26.5萬張
大股東要賣股票需要申報 沒事也不會去動作
所以在外面實際流通的股票數量由30萬張快速減為3.5萬
爆量數字自然就不能用30萬張來計算了
2. 突發的爆量可能伴隨著其他原因 而不是過熱所致
例如ETF成分股調整 MSCI權重調整 期貨結算
或特定商品影響(權證 個股期貨 公司債)
這種狀況必須同時留意消息面的變化
若功課做不足 很有可能太早/太晚殺出持股
像股本25E的儒鴻 在外流通的股票數約18萬張
2013/8/30的爆量1.17萬張看來是十分突兀
不過其實當日為MSCI調整日 周轉率突然上升是可預期的
傳統的計算方式都是以"10%"做為過熱的門檻
[有沒有發現"10"常常出現 其實這是心理學上的迷思哦!]
而實務上 只要量放大到近期的天量 我都會留意一下周轉率
(不過一般軟體的周轉率資料多為成交量/總發行張數
建議依照上面所提的董監持股調整一下)
爆量換手不是壞事 也沒有絕對值做為一定完蛋的指標
經驗上 爆量那天的K棒若為偏多方的紅棒或跳空格局 多半不用擔心
若是上下影線太長 或黑棒過大 又見了近期最高的周轉率
就要小心 是"誰周轉給誰"了!!
