Episode notes

INSIGHT

Hyperscaler CapEx Is A Systemic Risk

Major risk: hyperscalers' rising CapEx could create diminishing returns and depress free cash flow for top firms.
Because the S&P behaves like an "AI index," such a pullback would hit many correlated stocks simultaneously.

INSIGHT

COVID Desynchronized Economic Cycles

COVID changed business cycles by desynchronizing industries and altering cycle amplitude and periodicity.
That fragmentation helps explain why macro indicators have failed to produce a uniform recession signal.

INSIGHT

Less Perishable Inventory Shields Margins

Modern US equities have less perishable inventory, reducing margin downside in downturns compared with past manufacturing-heavy markets.
This structural change helps explain why stocks can outperform a weaker real economy.
