台積電定期定額與投資買賣心理分析
一、台積電定期定額:
台積電長期看好,散戶如要投資,如何因應下列5個狀況?
一、追高之後下跌,慘遭套牢?
二、看著一直漲,不敢買。
三、耐心等下跌,真的跌了,卻又不敢買。
四、買了之後續漲,是否要加碼或停利?
五、一張要65萬,買不起整張。
如何因應上述5個狀況?定期定額或許是個方法。
假設台積電每月穩定上漲或下跌5元,每月扣5000元買台積電零股,到年底成本6萬,從
650元買到705元,共買進89股,總成本6萬元;與1月份單筆買進6萬元,買在650元,共買
92股相比較,各種情況分析如下:
一、股價每月穩定上漲5元:
單筆買進績效:8.46%(暫不計配息)。
定期定額績效:4.46%(暫不計配息)。
二、股價每月穩定下跌5元,到年底為545元:
單筆買進績效:-8.46%(暫不計配息)。
定期定額績效:-4.13%(暫不計配息)。

買股票不怕放長,怕的是長期套牢,資金卡死,帳上績效負的,每天都很難過
台積電長期看好,但投資人仍害怕短期套牢,猶豫是否追高,因此考慮定期定額,
在自有資金能力範圍內,持續參與行情。
台積電在109年7月28日連續2根漲停來到466,卻收高檔長黑K,一直到109年11月16日
一根突破長紅K才解套,才有後來的大波段,因此,不想高檔追高套牢的投資人,
沒有那麼多錢的投資人,想要一次解決上述5個問題的投資人,
定期定額或許是個方法。
二、台積電投資心理分析
股價反應未來,如依董事長在法說會預測,台積電未來每年以10至15%成長,保守抓每年
成長10%,那麼預估未來3年EPS及股價如下(假設本益比30倍):
2021年:EPS=22元,股價660元。
2022年:EPS=24.2元,股價726元。
2023年:EPS=26.62元,股價798元。
因此喊出800元未必是天方夜譚。
但股價反應未來,如估2021全年EPS為22元,1月份股價就已反應完畢,
如果還要再漲,就是反應明年或後年的獲利,
令我想起市場心理分析與買賣機制
當市場所有人都一面倒看好時,大家手裡都有股票,大家都只想著在更高的價位出脫獲利
走人,此時反而是股價反轉時,因為已經沒有後續的買盤,大家手裡都只有股票,沒人再
願意以更高的價位買入。
例如前陣子某航運股,當市場看好該股,喊到50元時,人手一張航運股,大家都只想在50
元下車,沒人願意用50元的價位買入,試問50元沒有買盤,如何能賣出?
該檔航運股1/5最高來到45元,也就是目標價的九折,之後崩跌,1/20最低來到30元。
令我想起,該檔航運股,究竟有沒有45元以上的買盤?是不是大家都想要在45元以上出脫
沒有人願意用更高價買入,才會造成崩跌?
台積電亦同,當目標價喊到800時,打九折是720元,當大家都想在800元以上賣出時,誰
會用800元買入?
參考台積電109年7月28日的走勢,台積電如果要做頭,可能需要1根高檔暴量長黑K。
如果3年後,台積電還能再繳出年成長10%的成績單,那又是另一個故事了。
