The rebound from 1266.74 to 1335.52 can be either
1. A trend change or
2. A part of the corrective bounce that would make ABC pattern (wave 2) of a bigger bearish market started from 4/2/2012.
The pullback yesterday looks as a part of the corrective of the move from 1266.74 to 1335.52.
This may make the a?b?c? pattern as showed in the chart.
Bulls can win the high of yesterday 1335.52 or not depends all on what will happen in Greece.
