3，如何買。昨天說過：順勢交易如戲水，震蕩交易如玩火，逆勢交易如觸電。因此，買入應該買趨勢向上的板塊。如下圖：

	TREND	POTENTIAL (UP)	POTENTIAL (DOWN)	SUPPORT	RESISTENCE	OVER BOUGHT/SOLD AND TRAP	BUY	EXIT	CUT
XLP	TREND UP	0.58%	1.44%	55.20	56.34		55.99	58.79	55.7
XLU	TREND UP	1.82%	0.44%	54.26	55.49		54.26	56.97	53.9
IYR	TREND UP	1.07%	0.94%	79.44	81.05		80.10	84.10	79.7
IYT	TREND UP	2.62%	0.76%	187.03	193.40		187.44	196.81	185.9

4，買入之後繼續暴跌怎麽辦？首先，順勢交易再加上恰當的介入時機，贏率應該在90%以上。其次，萬一那10%較小的概率發生了怎麽辦？很簡單，每個買入點之後都有一個較為緊湊的止損點。這就是順應趨勢，截斷虧損，讓利潤奔跑的精髓。
