Foreign private money keeps flooding into American stocks. Over the past year through September, non-U.S. investors scooped up a staggering $646.8 billion in equities—an all-time high. That's serious capital migration.

What's driving this? Could be the dollar's strength, tech sector dominance, or simply a flight to perceived safety. Either way, this kind of institutional appetite tells you where the smart money sees opportunity. When global players pile in at this scale, it's worth paying attention to what sectors are getting the bulk of that flow.
