A strong end to a firmly bullish week. Markets gapped up on strong earnings from GOOG, CAT and C. But momentum faded into the second half of the session. I'll be watching gap support tomorrow, but doubt it will hold unless we get a catalyst early Monday.

Of the hundreds of companies reporting earnings the week of April 21st-25th some of the bigger names include: Monday: ALDN, ACI, BAC, LLY, GCI, MRK, NVLS, STLD, and TXN... Tuesday: AKS, BHI, CME, COH, LMT, MCD, NCC, PAS, UAUA, UNH, WU, BRCM, CREE, CYMI, NSC, VMW, YHOO, and YUM..
