Intel lost 28.58% of its value in one trading day.

The stock closed Friday at $65.76, down from $92.07 the day before.

The trigger was the outlook, not the past quarter. Intel actually beat on earnings, but it warned that PC revenue will stay weak through the first half of next year, and the stock gapped straight down at the open. Amazon added to the pressure: it missed on earnings ($1.89 a share versus $1.96 expected, per CNBC), ad sales grew 12% when analysts expected about 18%, and it reported a $42.4 billion free cash outflow over the past 12 months as it keeps spending on AI.

The whole market felt it. The S&P 500 fell 2.16% to 7,553.50, its third straight losing week, and the Nasdaq dropped more than 3%. Per Yahoo Finance, the Nasdaq was on track for its worst month since March 2025. After Alphabet's record drop on Thursday, this was the second day in a row that Big Tech's AI spending got the blame.

My rough-week checklist:

1. Step away before you act. Trading to "win back" a loss on a red day is how small losses turn into big ones.
2. Check how much of your account rides on one theme. Many "different" tech stocks and index funds are really the same AI bet.
3. Remember that the market is closed for the weekend, but news isn't. Anything you hold can open Monday at a very different price.
4. Write down your plan for Monday tonight, while you're calm, not at the opening bell.

That's what TradeShield is built for: rules you set while you're calm, so a bad day stays a bad day and not a bad month.

Stay sharp out there.
