The S&P 500 fell 1.2% on Thursday, its worst day since July.

Yet most U.S. stocks actually went up.

That's what a concentrated market looks like. The index closed at 7,663.43 and the Nasdaq dropped 2.6% to 26,008.86, its biggest fall since June, while the Dow edged up 0.02% to 52,867.98. The damage came from chipmakers and the giants building AI data centers. Meta fell about 7% after reporting its first cash outflow in more than a decade because of AI spending, Amazon lost 4.6%, Alphabet 3.2% and Microsoft 2.2%. The Philadelphia Semiconductor Index is now down about a quarter from its June 22 record high.

Oil added to the pressure. Brent crude jumped about 4% to roughly $113 a barrel, its highest since May, on worries about the war with Iran, and U.S. crude briefly topped $100. Higher oil revived inflation worries, and Bitcoin gave back its week's gains, sliding from near $85,000 to a low around $81,300.

A quick check on how concentrated your own risk is:

1. List your five biggest holdings and add up what share of your account they are. If it's most of it, one sector's bad day is your bad day.
2. Check whether those names really move for different reasons. Five AI or chip stocks are closer to one bet than five.
3. Know what an index fund holds. A handful of tech giants carry a big share of the S&P 500, so "diversified" can still lean hard one way.
4. Decide your max loss per position before the market decides it for you, and set the stop or size to match.

That's what TradeShield is built for: showing you where your risk really sits before a day like Thursday finds it for you.

Stay sharp out there.
