[心得] 台股報酬指數
台股報酬指數在2003年推出,由於考慮還權息,所以用以計算報酬率的話
會比較接近實際情況,比方說2003年一月台股報酬指數約在4500,
現在約在16000,因此報酬率約有255%,距離1990年的12682也超越了一截
但是,報酬指數還是有它的問題,比如沒有考慮到通貨膨脹率,
股息殖利率若是3%,不過若是今年的通膨率也達到3%,
等於把股息殖利率通通吃掉,反之若是達到4%,則形成負殖利率,
1990年至今通膨增加40%,若以當今16000的位子扣除通膨率,
則以1990年通膨指數100為基期計算出來的實質報酬股價指數
16000/1.4=11428 反而還低於當年的12682
實質報酬指數可以自己拿通貨膨脹率去除來計算,會比較接近真實狀況,
當然我也希望有朝一日交易所願意編出這樣的一個指數出來給大家參考,
畢竟經濟成長率,薪資成長率,利率都有編出扣除通膨的實質率,
股票是金融商品,投資目的多少也有抗通膨,推出實質報酬股價指數
除了讓投資人了解實質報酬率外,也能看出在通膨下股票的抗通膨率,
值得思考做這樣的動作
