The macro backdrop

Every theme swims in this tide — judge the week’s moves against it.

📅 On the calendar — and why it matters here

• Sun Sep 20 — FOMC (Fed rate decision / minutes). the single biggest scheduled market mover — a rate surprise in either direction repriced everything, hardest on rate-sensitive names (growth, REITs, utilities, homebuilders). Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Tue Sep 29 — JOLTS (job openings). labor-market tightness — a cooling read eases wage-inflation fears. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Wed Sep 30 — GDP. the broadest growth read — confirms or breaks the soft-landing thesis. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Wed Sep 30 — PCE inflation (the Fed's gauge). a hot print pushes rate-cut odds out (pressuring long-duration assets); a soft print does the reverse — one of the highest-impact releases. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.
• Fri Oct 2 — Jobs report (payrolls + unemployment). sets the growth-vs-recession narrative — a weak number lifts recession odds (hits cyclicals, consumer, financials); a strong one can paradoxically pressure rates. Watch for a surprise vs expectations — that gap, not the number itself, is what moves markets.

What to watch next
