SP500 - bullish 5th wave?

This count suggests that a 4th wave correction may have completed with the a and c waves being equal to one another and a 5th wave may have just started. In favour of the count is some nice alternation with the 4th wave finishing on the 0.618 fib retracement while the 2nd wave completed on the 0.382 fib. For me, the bigger question is whether the 4th wave correction has in fact completed or is there still another way down.
