Getsymbols從雅虎拿到的股票資料有6列，
XLF.Open XLF.High XLF.Low XLF.Close XLF.Volume XLF.Adjusted
其中比較tricky的就是Adjusted。網上找到的內容很多，但是都不太細緻全面，對於非金融專業的人來說，理解還是比較困難。 今天就來細說一下。其實也很好理解了。

因為收盤價本身可能不能完全反應股票的價值，比如現金分紅，股票分紅，股票分割。
1. 現金分紅：股票的調整價格應該在收盤價的基礎上減掉現金分紅的部分。比如XYZ公司收盤價是20塊錢，收盤後公司宣佈會每股分紅1.5塊，那麼股票調整價格就是18.50塊。（非常容易吧！）
2. 股票分紅：如果公司決定不分現金，而分給你股票。比如公司宣佈2:1的股票分紅，也就是每一份股票會分給你兩份新的股票（這只是個例子）。那麼股票調整價格就是$20*(1/(2+1))=6.67塊。
3. 股票分割：如果是2:1的股票分割，那麼意味著每一股會得到一股新的股票。那麼股票調整價格就是$20*(1/(1x2))=10塊。
簡單來說，調整價格能更好的反應出股票實際的價格。
During the course of a trading day, many things can happen to affect a stock's price. Along with good and bad news relating to the operations of a company, any sort of distribution that is made to investors will also affect stock price. These distributions can include cash dividends, stock dividends and stock splits.
When distributions are made, the adjusted closing price calculations are quite simple. For cash dividends, the value of the dividend is deducted from the last closing sale price of the stock. For example, let's assume that the closing price for one share of XYZ Corp. is $20 on Thursday. After close on Thursday, XYZ Corp. announces a dividend distribution of $1.50 per share. The adjusted closing price for the stock would then be $18.50 ($20-$1.50).
If XYZ Corp. announces a 2:1 stock dividend instead of a cash dividend, the adjusted closing price calculation will change. A 2:1 stock dividend means that for every share an investor owns, he or she will receive two more shares. In this case, the adjusted closing price calculation will be $20*(1/(2+1)). This will give you a price of $6.67, rounded to the nearest penny.
If XYZ Corp. announces a 2:1 stock split, investors will receive an extra share for every share they already own. This time the calculation will be $20*(1/(1x2)), resulting in an adjusted closing price of $10.
