Will markets continue to rally?

That is a very difficult question to answer. My charts indicate that the damage inflicted on Thursday is not yet over. We probably have only two more days up here near this level. What can cause volatility on each side? Tons of earnings this week. Citi reports Monday morning. INTC, YHOO report on Tuesday evening. GOOG is reporting on Thursday. Add some more volatility- Oct options expire on Friday. Be prepared to brace a wild market.
