Index rebalancing is less about “good stocks getting better” and more about mechanical capital flows.

The key point this time is the Sep. 21 rebalance: S&P 100 added DELL, PANW, ANET and SNDK, while S&P 500 added BE, P and ILMN.

For investors, the interesting part isn’t simply the headline inclusion—it’s the mismatch between forced buying and market expectations. Passive funds must adjust positions, but active traders often anticipate these flows beforehand. By the effective date, part of the demand may already be priced in.

That creates a subtle setup: index inclusion can provide liquidity support, but it cannot manufacture earnings growth.

So I’d separate two signals: index flows tell us where money must move; fundamentals tell us whether that money has somewhere to stay.

The real question isn’t “Which stock gets added?” but “What happens after the forced buying is finished?”
