0. Bottom line first

Rather than overcomplicating it, I am recording the recently broken-out high as the line to watch for whether the bubble is breaking.

The key is whether Alphabet holds the newly cleared high.

1. What changed

Volume increased and the stock broke through prior highs. In this zone, I think the cleanest check is simply whether it falls back below the newly broken-out high.

Interpretation: I still think Alphabet may soon become the largest company by market cap, but if it breaks the recent high it just cleared, I would consider sharply reducing equity exposure for a while.
