|First Trust Exchange-Traded AlphaDEX Fund - First Trust Consumer Staples AlphaDEX Fund|
|The investment seeks investment results that correspond generally to the price and yield (before the fund's fees and expenses) of an equity index called the StrataQuant(R) Consumer Staples Index.
The fund will normally invest at least 90% of its net assets in common stocks that comprise the index. The index is a modified equal-dollar weighted index designed by NYSE Euronext to objectively identify and select stocks from the Russell 1000(R) Index in the consumer staples sector that may generate positive alpha relative to traditional passive-style indices through the use of the AlphaDEX(R) selection methodology.|
