因為資訊和市場是一個非常浩瀚的海洋
我無法知道,到底有幾千幾萬幾億種因果關係在市場裡角力
市場是物理裡,幾億種力量最終「合力」的結果
失業率創新高的資訊當然有在這裡面,但你不知道其他力有多少
實際上,由於之前市場裡很多分析把失業率想得還更高,還有喊到700萬的
結果公布出現之後,反而是樂觀
效率市場理論是對的
市場也永遠是對的
我們看錯只有是我們不對的問題 XD
※ 引述《AppleMan (感恩惜福の芒果♥)》之銘言:
: 小妹我剛接觸證券市場不久
: 對於很多專業術語還不是很明白
: 最近在板上看到很多人在談"效率市場理論"(Efficient Market theory)
: 主要論點是
: 在一個有效率市場下
: 所有影響股票價格之資訊將被市場吸收
: 充分反映於股票價格上
: 不過R
: 從現實上觀察
: 像是前陣子美國政府公布失業率創新高的資訊
: 理論上證券市場或多或少會下修
: 可是當天美股卻是上揚的情形
: 想請問各位股版的前輩悶
: 這葛理論484在當前的情形
: 已經無法適用呢?
: = =
