股票市場是投資人期望獲得薪資外所得的管道,投資人之所以願意將資金投注於股票市場,乃是希望藉由承擔合理的風險以獲得可觀的報酬。市場中因存在資訊不對稱的情形,導致優先掌握市場資訊的投資人可優先取得市場先機,賺取超額報酬,也就是80%人賠錢,20%的人賺錢;而網際網路的興起,提供世人一個廉價且可迅速收集資訊的平台,可降低資訊不對稱的程度,但哪些資訊需求是投資理財所需的呢?這是本研究要探討的。網際網路上的投資網站很多,這些網站提供的資訊品質、多寡是否有差異呢?本研究針對入口網站、媒體、財經網站、卷商網站等四類分別觀察台灣、美國各2個網站,共16個網站,並加以分析比較。 本研究所得之結果如下: 一、每種分析所持的基本論點都是對的,但必須看是從哪一個角度來看;各種工具從不同的角度來靠會有不同的解釋,因此捉住工具的本質內涵,才能建立正確的交易工具,否則錯用工具只會讓自己的資產不斷縮水而已。 二、整體而言,各類的投資網站各有其擅長之處,台灣的理財網站也不如大家所預期的皆不如美國網站,投資人可依據自己所要投資的地方,選擇最符合自己使用習慣的理財網站,獲得所需的理財資訊。畢竟在這21世紀裡,成功的投資人是屬於懂得搜尋所需資訊的人。 Stock market is a way that investors expected to earn extra income besides salary.
