Are those GAAP eps? If so, given the impacts from tax law changes and charges that companies have been taking on their Q4 income statement results, I don't think TTM eps numbers will be especially helpful this year. Arguably, the smaller companies should benefit the most from changes in the federal corporate rates since most of them operate primarily in the US.
Also, what about non-cash items like Stock comp exp, amortization charges, one-time exp/inc....??
