A massive bear market rally has just begun

What I've shown in this video is an indicator to determine market breadth. When breadth reaches the extreme lows (like it did 2 weeks back), massive multi year bottoms have followed. However, this time I think it'll just be a multi week bear market bounce as we are in a long term bear market.

TAKEAWAY: SPY could go up to ~430 which would translate to ~17% rally from the bottom. Time frame is approximately early August.
