翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク A Random Walk Down Wall Street ： ウィキペディア英語版 A Random Walk Down Wall Street ''A Random Walk Down Wall Street'', written by Burton Gordon Malkiel, a Princeton economist, is an influential book on the subject of stock markets which popularized the random walk hypothesis. Malkiel argues that asset prices typically exhibit signs of random walk and that one cannot consistently outperform market averages. The book is frequently cited by those in favor of the efficient-market hypothesis. As of 2012, there have been eleven editions and over 1.5 million copies sold.〔Burton Malkiel (2011) (''A random walk down Wall Street: the time-tested strategy for successful investing'' )〕 A practical popularization is ''The Random Walk Guide to Investing: Ten Rules for Financial Success''.〔Hardback: ISBN 978-0-393-05854-3, Paperback: ISBN 978-0-393-32639-0〕 ==Investing techniques== Malkiel examines some popular investing techniques, including technical analysis and fundamental analysis, in light of academic research studies of these methods. Through detailed analysis, he notes significant flaws in both techniques, concluding that, for most investors, following these methods will produce inferior results compared to passive strategies. Malkiel has a similar critique for methods of selecting actively managed mutual funds based upon past performance. He cites studies indicating that actively managed mutual funds vary greatly in their success rates over the long term, often underperforming in years following their success, thereby reverting toward the mean. Malkiel suggests that given the distribution of fund performances, it is statistically unlikely that an average investor would happen to select those few mutual funds which will outperform their benchmark index over the long term. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「A Random Walk Down Wall Street」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
