I agree, MM. Anytime a price level is viewed as particularly significant, it tends to offer support and/or resistance.
So, the 200 SMA should offer resistance for psychological reasons, (if nothing else), because: [1] as the old adage says "bulls live above the 200 DMA, and bears live below it"; [2] plus, for the past three years we've lived mostly below it, thus getting over it would be considered a major event.
