FAD's selection and weighting methodology sets it apart from peer segment funds. The fund uses the AlphaDEX methodology to pick growth companies from three different size segments of the Nasdaq US Select Index Family. From each segment, growth stocks are screened based on price appreciation, sales growth and sales-to-price ratio. Once the fund has selected those firms best positioned for growth, it employs a tiered weighting strategy that assigns weights of 50% to large caps, 30% to midcaps and 20% to small-caps. Although FAD holds a broad portfolio of growth stocks, it tilts small, underweights technology and takes on more market risk. The index is reconstituted and rebalanced quarterly. Note: On April 8, 2016, the fund switched underlying indexes from the old Defined index to the current Nasdaq version. The index universe may differ slightly but the factors and methodology are the same.
