Fib Levels

SPY broke down in a dramatic way late in the day (finally).
It came to rest right in the 78.6% retracement level, as measured from the close on 11/30 (61.8% if measured from the swing low of that day).
I traded AIG short this afternoon as it broke down from it's $30.50 base.
I'm still looking for a climactic move down in this name to test recent lows. Next level of support is the $29 level as mentioned in a previous post.
