While I would like to be an optimist and believe that we are mostly out of the woodwork, that's not what I would be banking on. For the latter half of last month, the SP index rallied hard right after having created a new low, it would be easy to assume that the new low constituted a second wave down and that now the correction is over and the bullish trend should resume. The next days will prove most revealing, I expect the price to resume falling sometime this week or next.
Ultimately if the price breaks above 4157.0 we might have to rethink the scenario though not outright discard it. If the rally continues and breaks above 4333.0 the outlook is invalidated and we will likely see a bull market continue.
