Three recent calls, what happened next, and three chart habits you can use yourself.
If you own AI stocks, this week hurt.
On Thursday, the Nasdaq had its worst day since April 2025, down 5.5%. US chip stocks fell 12% in a single day. And it wasn’t about bad results. AMD had just reported record revenue and still fell 17%. Investors were worried that the new Democratic Congress would slow down the building of AI data centres.
So is this a dip to buy, or the start of something bigger?
Robin Ho has traded for more than 25 years, and he doesn’t try to predict the news. He reads the chart. He marks where the price is likely to stall or bounce, and decides in advance where he’s wrong. His RHO Navigator indicator draws those levels for him.
You only need two terms for this article. Support is a floor the price tends to bounce off. Resistance is a ceiling it tends to stall under.
Here are three of his recent calls, and what each one teaches.
1. Oracle. The Long-Term Trend Was Up. He Sold Anyway.
The call. On 7 October, with Oracle at about US$144, Robin said to sell into strength.
What happened. Oracle is down about 20% since, as investors grew worried about how much it is borrowing to build AI data centres.
The lesson. Oracle’s long-term chart was still pointing up. Its short-term chart was pointing down. Robin traded the short-term trend, and kept his eye on one level on the long-term chart, about US$114, the stock’s July low. If Oracle breaks below it, the long-term uptrend is in trouble too. Right now, it’s sitting just above it.
This is how the same call looked on Robin’s own chart on 7 October. The Navigator still read the long-term trend as up (top right), while he was already planning to sell.
2. US Chip Stocks. When a Floor Becomes a Ceiling
The call. Since July, the US chip index had been bouncing off a rising floor. In late October it fell through it. On 28 October, Robin pointed out that it had climbed back up to that broken floor, and treated it as a ceiling.
What happened. The index turned down and fell about 22% in just over a week.
The lesson. When a price falls through a floor, many people who bought near it just want their money back. So when the price climbs back there, they sell. That’s why an old floor often becomes a ceiling. You can spot it on any chart.
3. The Dow. Right in the End, but Would You Have Lasted the Night?
The call. On 4 November, Robin flagged a level on the Dow Jones as a good place to sell.
What happened. That same night, the market cheered the US election results and the Dow closed above his level. A day later it reversed and ended about 2% below it.
The lesson. Robin got the direction right. But whether a trader made money came down to the stop loss, the price where you admit you’re wrong and get out. Set it too close, and the election night jump would have forced you out before the fall. Charts can’t see the news coming. So decide your exit before you get in, and keep the trade small enough that a loss is one you can afford.
Three Habits You Can Use
Robin isn’t right every time, and he’d be the first to say so. But the habits behind these calls work on any chart.
- Check the long-term chart as well as the short-term one. They can point in different directions.
- Watch for old floors that turn into ceilings.
- Decide where you’re wrong before you get in, and size the trade so any loss is one you can afford.
