Corporate buybacks — historically the single largest source of equity demand — are slowing. This matters more than most realize.

When companies step back from repurchasing their own shares, you lose the bid that's been propping up valuations during earnings misses, macro uncertainty, and stretched multiples. Buybacks don't care about sentiment or technicals. They're mechanical, predictable demand.

Now that demand is fading. Whether it's rising rates making debt-funded buybacks less attractive, tighter cash flow, or management teams getting cautious about overpaying at current prices — the effect is the same. Less buying pressure.

Technically, we're at a decision point. Support levels that held through prior pullbacks are being tested again. If buyback activity continues to decline while retail and institutional flows remain mixed, those levels may not hold this time.

The week ahead will clarify whether this is a temporary pause or the start of a more serious retracement. Watch corporate cash flow statements, buyback authorization announcements, and whether management teams are actually executing on those authorizations.

Markets loved the buyback era. The question now: what happens when the biggest buyer walks away?
