S&P 500 Bull Move Underway

My last comment on S&P 500 was the market has been pulling back in a channel and could break to the upside. The break up is exactly what we got and it's a lot to be thankful for. With Greece uncertainty at a lower level and Fed expectations clearer the market has decided to move up. My expectation is for a not-short lived moved. Can the market advance for 2-4 weeks?
