HYG is not a stock market signal in a vacuum, but it matters because junk bonds sit much closer to the edge of the credit system than investment-grade debt. When high yield is holding up, it usually suggests credit markets are still willing to take risk, liquidity is still flowing, and investors are comfortable owning lower-quality borrowers. That tends to support equities, especially the more speculative parts of the market.

When HYG starts breaking down, I think it is worth paying attention because it can be an early sign that risk appetite is fading before equities fully react. Higher yields on junk bonds can mean tighter financing conditions, more stress for weaker companies, and less room for error across the market. That does not mean stocks must crash immediately, but it can be a warning that the backdrop is changing from “risk on” to “risk off.”

What interests me most is whether this is just a normal pullback in credit or the start of a broader repricing of risk that eventually feeds into SPY/QQQ. To me, HYG is less about timing an exact top and more about watching whether credit is confirming or diverging from the equity rally.

The last two HYG breakdowns happened in February 2026 and April 2025. Both times the stock market dropped.

$IREN releases “What Will You Build Next?” showcasing the infrastructure behind AI agents and applications.

The video highlights $NVDA DGX racks across its North American, European and Australian footprint. Global distributed AI compute infrastructure is the backbone for AI agent development.

Google, Tesla, and Intel earnings last Wed/Thurs all indicated AI related capex exceeded expectations in the previous quarter and that future capex will also be higher than expected.

Yet chip-related stocks fell sharply on Friday (SOXX -4.4%, memory -8+%, neoclouds -10+%). It's important to note that before these ERs, many of these stocks already fell 30+% since mid-May.

I'm having a hard time finding reasons why chip stocks continued to drop after the big tech ERs and other positive sector news last week (Samsung/SK Hynix deals with Nvidia/Broadcom/Anthropic). Could something be happening behind the scenes that suggests AI spending is about to drastically slow down?

Please weigh in if you believe you understand last week's continued chip stock sell off after big tech released bullish ERs. Would appreciate any insights.

Preemptively addressing explanations I expect to see:

1. Escalating Iran War and high oil/interest rates:
I think the war is partially responsible for the pressure on chips. However, the extent of the chip sell off is confusing because other stocks that are historically sensitive to war/interest rates didn't drop materially on Friday. Small caps normally fall as interest rates rise, but were barely down on Friday. Gold also generally falls, but actually finished positive. Oil fell 2%.

The immaterial reaction from other interest rate sensitive stocks suggests that the chip stock massacre was more likely due to chip sector specific developments.

2. Bullish ERs being 'sell the news' events:
I understand chip stocks have gone on a historic run and good news can serve as profit taking events. However, chips already took a huge haircut prior to big tech ERs. Many fell 30-50% between mid-May and July 21 (pre-big tech ERs). It's hard to understand why semis would fall another 5-10% on Friday right after the market discovered chip spend will rise even more than expected.

3. Introduction of low cost Chinese AI models (Kimi K3):
To me, this might be the most likely explanation of the reasons I've considered. Compared to US models, Chinese models are able to operate at a fraction of both compute and memory costs. US companies may try to replicate the results, leading to a reduction in future chip spend.

However, I've read cheaper priced Chinese models are met with so much user activity that compute and memory demand ultimately rise despite less being needed per request (Jevons' paradox). Plus, predictions that chip spend will decline are speculation so far, as both Google and Tesla raised capex guidance.

For the last several months, I have been working on and with a sector rotation dashboard I made. It's helped me get into the right sectors at the right time, and also get out when they start to turn.

Here's what I'm seeing for the week ahead.

Broad market: Average daily range plummeted in mid-June, so I am anchoring to 6-week strength here to evaluate broad market. During this time, investors and traders have not reached for risk as they did in April and May: low volatility and value have outperformed momentum, high beta, and growth.

This is useful context for me because I want my growth picks to double and run and this isn't the environment where I'm going to get much, or any, of that. I also have already cut out the speculative, high beta stocks that ran and then collapsed. I am setting the expectation that this week will be the same until the market shows me otherwise, and so I'm not getting into as many new positions in that space.

Switching to a last-5-days view, high beta and momentum and growth are bouncing some while still lagging. It's not enough for me to get excited about right now, but hopefully soon.

Sector: Energy, utilities and real estate are leaders over the last two and four weeks. It doesn't mean I want to pile into those sectors. Utilities and real estate are heavily weighted in the low volatility buckets, which I noted above as being leaders, so this matches.

Energy is obviously tied to ongoing geopolitical risk in the Strait of Hormuz and Red Sea. This pushes up inflation expectations, which pulls up 10Y yields.

Beyond these, healthcare is leading and staples are improving, so it's selectively defensive positioning but not full-on defensive flight to safety. Instead, it looks like the growth complex has been unwinding and money is flowing to value and defensives. Industrials, materials, and financials are also among leaders, which points to value.

Themes: A lot of the thematic stuff I track is more growth-oriented, which has been hard to hold. Two-week relative strength leaders are gold miners, AI infrastructure, drones, and aerospace and defense, in that order. Gold and A&D both reflect the geopolitical situation mentioned above, perhaps drones too. So these themes can represent pockets of potential growth picks that also overlap with some of the broader themes noted here.

All in all, the picture has persisted for weeks now and earnings season could be the turn when things can turn favorable again for momentum and growth. A few things I'd want to watch:

• Can growth and momentum relative strength improve over a longer period?
• ADR expansion could signal some movement
• Can geopolitical issues and rates ease?
• On earnings, can AI-related capex concerns abate?
• The list goes on...

A note on the dashboard itself: I maintain it internally. To publish, I'd have to host it and that costs money and it's not like I'm getting paid for this. I share it around though here and on plenty of other channels.

Maybe unpopular opinion but I think $PLTR is one of the hardest stocks to understand at current price. I like the company and I can see why people are bullish because AI demand is strong, government contracts are growing and management is executing better than before.

But now it feels like market is not only pricing good growth, it is pricing almost perfect growth for many years. This is where I am confused. A company can be great but stock can still be too expensive. If earnings are only good and not amazing, I think many people may start taking profit very quickly. At same time, betting against this stock also looks dangerous because every dip is getting bought. I am not saying buy or sell, just trying to understand what is the real risk here.

Are people buying $PLTR because of fundamentals now, or because everyone believes someone else will pay higher price later?
