由零開始學習股票-股價越高等於越貴?

文章難度:★☆☆☆☆ 曾經聽過樓下陳師奶講:「建行(939)只係得7蚊左右,相反恒生(11)成200蚊,咁一定係恒生大隻穩陣好多啦。」 如果你都有相同既諗法,睇黎你未搞清楚股價同市值既分別。 總市值=股價 x 已發行股份數量 代入番去陳師奶既例子,以6月19號收市價計算。 建行總市值=$7.2 x 2500億已發行股份數量 =18000億 恒生總市值=$195 x 19.12億已發行股份數量 =3728.4億 所以建行實際上是比恆生大4倍。當中的已發行股份數量,公司要發行多少量是有點arbitrary,而且發行量也是可加可減的,可以配新股也可以回購注銷,但總之記著市值才是重點就夠了。 另外,股票總市值越大,都未必代表股價走勢越穩定。以前藍籌股聯想控股(0992)為例,之前600億的市值夠大隻了,但這一年來累跌了近兩成,還被剔出恆指成份股。所以大隻的藍籌未必代表穩定。 所以,陳師奶既說話有兩大錯處。 1️⃣股價不等於市值 2️⃣市值高不等於穩定
