Are we resting or about to fall off our perch?

I always get surprised by how traders and investors can see a 1.9% fall from an ATH as a reason to run for the hills. Trend corrections on the Nas in most uptrends have averaged 3-4% without harming the trend. Last year's uptrend started in March and didn't end until August, the biggest pullback in that time was 4.7%. I suspect a new uptrend started in early May and I'm assuming it will continue for a while. I'll change my mind quickly if I see evidence of a character change - maybe I should be a politician?
