I know not perfect (and neither is my drawing yet) but I keep seeing this pattern. It will be interesting to see where this goes next.

We have the two little spooky forms circled for both periods, and in 2007/08 that was followed by consolidation with a slight downwards slope and then a big move with a big spooky form at the end and a big drop! Scary and not a Dry Martini in sight 🙂
