Qualitative Research & Evaluation Methods ---- book review

What I learnt losting a million dollar cited in a book called Qualitative Research & Evaluation Methods

but what he reports learning the most from was a highly unusual combination of mistakes in which he lost more than $1 million in a few weeks of trading soy beans---an extreme but illuminative case.  He reports that he ultimately learned to a winner by carefully studying and learning from losing.

Stephen Covey's(1990) best-selling book "The 7 Habits of Highly Effective People is Based on a purposeful, extreme group sampling strategy.

Sometimes cases of dramatic failure offer powerful lessons.

Teh legendary UCLA basketball coach John Wooden won 10 national championships from 1964 through 1975, an unparalleled sports achievement. But the game he remembered the most and said he learned the most from was UCLA's 1974 overtime loss to North Carolina Statein the semiifinals(quoted in the Los Angeles Times, December 21, 20000).  Wooden's focus on that game---that extreme case---illustrates the learning psychology of extreme group purpsepful sampling.

DQ 我讀到的幾位大師的   Confession 他們在偶然的帖子裏都承認在 wipe out 幾次之後
才知道應該怎樣去操作   這也許就是  本書提供的理論依據   但是  wipe out 太可怕了

如果能夠用什麽東西來替代在 learning 上的獲得是最好的  也許這種替代根本不存在

我在研究用交易次數  來替代最終的 wipe out 從而獲得認知 learning
根據目前的經驗和研究 我認為是 至少在這個大方向上是有明顯效果的
我的假設是當你累計交易次數到一定的量必然發生質的變化  而這個質的變化便是 從wipe out 而獲得的認知
我對交易次數的累計應用在投資的不同領域進行實際試驗 對股票期貨和
外匯交易 以試圖不被wipe out而達到和wipe out之後的同樣效果的認知
另一個因素就是時間 當然時間要花的長一些需要耐心持久 投資是一件很枯燥的事情 營利隻是使我們能夠做下去的保證
是事業的保證

這本書似乎是一本社會學研究的科學理論書 我是通過查找另本書What I learnt losting a million dollar而發現這本書的
但裏麵的一些內容的闡述似乎讓我可以把他應用到投資的理論上去 研究投資的理論是讓我們找到更正確更能夠理解和分析
使我們能夠將他應用到實踐中去 最終使自己習慣於這種交易

下麵我要談到另一個很重要的觀察 obervation
