簡單解讀：截至上星期五收市止，未平倉期指合約中，10大期指好倉共有91,709張，佔未平倉合約的88.5%，當中最大單一好倉佔23.94%；10大期指淡倉共有78,259張，佔未平倉合約的75.78%，當中最大單一淡倉佔15%。以上數據說明，大戶持有好倉的比例是遠高於淡倉，相反而言，散戶持有淡倉比例是遠高於好倉。
以上數據反映大戶看好比例較高，而散戶看淡比例較高。當然，期指尚有許多其它用途，例如作為對沖工具、鎖定回報/入貨價位等，所以期指數據並不一定可以準確預測後市，但有時極為懸殊的數據則甚具參考價值。

it does look like it at this moment but my guess is it cant last till the end of the month. 5 , 941, 13 alot of the big blue chip made new highs already. The chinese banks earning coming out in the 3rd week. Afterwards, i dont see any incentive for the market to go up further."
誠如上述朋友所言，我自己覺得大市只是月初已去到如此高位，升幅顯著，如果不先行調整的話，很難可以長升長有。我自己看法是大市在本月中旬會先行調整，下試21000點支持，然後月底有機會升上22000點。
