PE應該點睇

如果有一間公司PE是100倍, 當盈利不變, 你投資下去要100年才回本, 你會不會投資這間公司 ???

如當作投機抄賣須需要有無限憧景才行, 就算盈利陪增越高PE都越危險

大升市時無人會講PE一路抄上去, 當跌下高PE股票一定跌得快和急

要分清楚自己是投資 / 投機

P/E即係市價/盈利率，簡稱市盈率，是以其市場交易價格相比其最近所公佈盈利做比較。市盈率假設是20，即係你用20蚊去買1蚊盈利，咁你話貴唔貴？唔同行業在唔同地區運作，其盈利增長亦會唔同，所以如果市盈率高代表市場期望盈利增長會高，相反市盈率低代表市場睇淡公司盈利前晚景，所以市盈率不能一本通書睇到老，要了解公司發展同管理層作風先好買。希望幫到你！

theoretically yes BUT

depend on the nature of stks

Say, technical stock--
because they need hugh capital investment n longer duration on returns, so usually for the first few years, the P/E ratio is v v high, but under yearly establishment, the returns comes in , thats will lower the ratio to a more reasonable lvl

Usually P/E is for comparative,

say one company's 07 P/E is 15

if it's original P/Eis 20 or 25 in 2006, thats means the company is making step forward n advancement

so take that ratio as ONE OF THE REFERENCE and added with others
