spx get ready to take a ride?

since we've been so crazy overbought, it stands to reason we'll have a pretty large retracement if things surprise to the downside. if that happens, i envision this scenario... hopefully i'm wrong. If we take prior drawdowns in consideration, a 30-50% move would bring us pretty close to these figures.
