What stands out

Liz Ann Sonders opened by pointing out something investors often miss: headline index gains can mask a lot of internal churn, winners and losers rotating under the surface. For investors who use Charles Schwab Corporation (SCHW) for custody, advice, or passive products, that internal churn matters because it drives client behavior, fee mix, and asset flows. Schwab is both a market mirror and a pipeline, so Sonders' framing turns a monthly market snapshot into a short essay on how flows and product performance reshape long-term returns.
