Magnificent 7 Heat
62/100
Hot — but earnings-backed
diversified · cheapconcentrated · manic
Record concentration and a ~$700B capex arms race run hot — but the valuation premium is the smallest in a decade and the earnings are real. The risk here isn't the multiple. It's whether the AI spend earns its return.

Why this isn't 2000
At the dot-com peak the biggest names carried a 100%+ valuation premium on under 20% of market earnings. Today it's a ~45% premium on ~30% of earnings, paid for with real cash flow. The genuine tail risk has moved: it's no longer the multiple, it's ~$700B a year of AI capex chasing a return that hasn't fully shown up yet — plus Tesla-style single-name froth inside the basket.
