一、華菱認沽權證基本情況
華菱認沽權證(038003)是2006年3月2日上市交易的歐式認沽權證，到期日為2008年3月1日，規模為6.33億份。初始行權價為4.90元，6月23日調整后的最新行權價為4.769元。
相比其它權證，該權證上市交易以來走勢平穩。見圖1。

二、華菱認沽權證保本投資組合策略
華菱認沽權證給我們提供了保本投資的機會。圖2中紅線為華菱認沽權證的行權價，粉紅線是每日華菱認沽權證收盤價與G華菱股票收盤價之和。粉紅線低于紅線的部分說明，在該交易日同時買入相同數量的華菱認沽權證和G華菱股票，可以確保投資不虧本，到期行權可以獲得無風險收益。
如2006年4月28日(此時距到期還有1.8年)，權證價格為1.206元，股票價格3.42元，兩者之和為4.626元，比當時的行權價4.9元低8.01%，即使考慮交易費用，也比行權價低7.62%。也就是說，該日買入華菱權證與G華菱股票組合的投資者，到期行權可獲得7.62%的無風險收益，遠高于同期存款利率。
7%以上收益率出現的機會并不多，持有該組合的目的也并不是為了獲得這個收益。我們知道，認沽權證與標的股票組合構成一個認購權證，即當G華菱股票上漲時，該組合價值將上漲。如果看好G華菱股票，就可在粉紅線低于紅線的位置買入權證與股票組合。如果G華菱如預期一樣上漲，該組合便可以較高的收益獲利了結；如果G華菱持續下跌，持有組合的投資者至少可以持有到期，通過行權獲得無風險收益，確保本金不受損失。
圖2 華菱認沽權證與G華菱組合走勢
從華菱權證及其它認沽權證的交易情況看，權證價格與標的股票價格之和低于行權價只是暫時的，會很快向行權價回歸并超出。而華菱認沽權證還有1年半到期，G華菱股價在此期間上漲機會很多，因此該組合獲得超過無風險收益的概率很大。
最近8個交易日，華菱認沽權證和G華菱股票收盤價之和一直低于行權價，給投資者提供了保本投資的機會。見附表。
負的溢價率表示到期行權有正的收益。最近一個交易日(8月14日)買入華菱權證與股票組合，至少可獲得無風險收益0.86%，去除交易費用后的收益為0.48%。
