The MANIA Stocks Are Tanking — Here’s How to Understand It (ELI5 Version)

What Was the Earlier Warning About?

Imagine someone pointing at a clock that’s broken and only right twice a day. That’s kind of like the author’s June 28 article.

• The author wrote about something called the M-A-N-I-A trade as either:
  • A real warning signal to pay attention to, or
  • Just a lucky guess (like a broken clock being right once in a while).

In this case, MANIA means a group of super-popular stocks. These are all among the biggest holdings of an item called the iShares Semiconductor ETF (SOXX) — think of an ETF as a basket that holds many stocks at once.

• SOXX made a big move earlier this year (its price went up a lot).

More News from Barchart
The author says: “I don’t make up stories. I just look at lots of charts using Barchart’s helpful, time-saving tools.”

Here is how the author ended that June article (in simple terms):

• From a plain chart-watching view, the momentum gauges showed a “dangerous exhaustion window” (meaning the upward speed was running out of energy).
• The semiconductor sector (chip companies) carried the whole weight of keeping the big stock averages from going red (down) this year.
• When one small theme carries everything, it’s like an accident waiting to happen.
• The author said: Make sure you have insurance (meaning protect your money).

How Are the MANIA Stocks Doing During July?

So what happened to these stocks in July? In one word: scattered (all over the place). More recently, each has had a mini-meltdown (a small crash).

Since the June 28 article (not counting Thursday’s big drop):

• MU and INTC each fell 20%
• NVDA bounced back 10% (it’s part of the “Magnificent 7” big tech group)
• AVGO went up 8%
• AMD jumped 10% in two days, gave it back, and by Wednesday was only up 1.5%

The author says: “Nothing to see here, right?” Then answers: Wrong.

There’s a lot to see:

• SOXX holds these five stocks at the top of its list.
• It puts about 40% of its money into those 5 names (about 8% each).
• The other 60% goes to 25 other stocks (about 2.4% each).
• So MANIA has a big say in how the market’s hot chip industry is doing.

Important Point
Just 5 stocks control 40% of the SOXX chip basket. If they wobble, the whole basket wobbles.

What the Charts Are Telling Us

Each MANIA stock has its own story, but the author thinks the charts look “different degrees of perilous” (sort of dangerous).

• SOXX is a blend of the 5 big names and 25 smaller ones.
• The author has been “aggressively shorting” (betting prices will fall) these with small amounts of money since the article.
• If you think every dip will be bought back up, that’s a big yellow flag — the odds of that are fading.

A PPO (a chart tool that shows momentum) in SOXX is giving back its big move from earlier this year.

• It’s just below the zero line.
• If it’s going to rally, it better do it soon.
• Below zero is where “rallies go to die” (upward bounces stop working).

Add these clues:

1. The 20-day moving average (average price over 20 days) is pointing straight down but still high.
2. The 50-day moving average is just starting to turn lower.
3. Together, this is a “perfect storm” setup for a trade that was remarkable and historic — similar to the year 2000 before it crashed.

Quick Update on Each of the Five Stocks

Micron Technology (MU)

• MU was a rockstar in the first half of the year because its special memory chips (HBM) were sold out through end of 2026.
• After IBM warned about something, MU dropped over 7% in one day.
• Short interest (bets it will fall) is at a 3-year high.
• If companies stop building data centers to save cash, 2027 supply could be too much (a glut).

Advanced Micro Devices (AMD)

• AMD is seen as the only real long-term rival to NVDA in data centers.
• But its chart keeps breaking short-term averages (a sign of weakness).

Nvidia (NVDA)

• The “king” of the cycle is showing tired behavior.
• It sometimes ticks green during washouts, but the price action is exhausting.
• If companies don’t earn enough from all the graphics processors they bought, NVDA could face a huge drop.

Intel (INTC)

• INTC shows “capital punishment” (huge pain) in tech.
• While peers hit highs, INTC was a “story stock” (propped up by US government investment).
• It plunged 11% in one afternoon as phone and PC demand softened.

Broadcom (AVGO)

• AVGO is where July anxiety began.
• It put out a misleading “Apple win” news release, then blew a hole in the bullish case during earnings.

Takeaways

The author sees no middle ground:

• These stocks will either be “dip-buying heroes” again, or
• The crease in charts turns into a crash.

This is less about company basics and more about:

• Liquidity (how easily things trade)
• Leveraged players (people using borrowed money) being punished

There is a tool: Direxion Daily Semiconductor Bear 3x Shares (SOXS)

• It’s a 3x inverse ETF (aims to move opposite SOXX, 3 times as strong).
• The author avoids put options (a type of bet) due to volatility.
• He uses tiny position sizes, stays nimble, takes profits fast.

Important Point
Managing risk is more important than ever. But you can still use volatility as a friend, not an enemy.

Rob Isbitts is a semi-retired CIO, former fiduciary investment advisor, and Barchart columnist. He had a position in SOXS at publication. This article was originally published on Barchart.com.

Summary

• The MANIA stocks are a handful of popular chip stocks in the SOXX basket.
• They carried the market earlier in 2026 but now show cracks.
• July has been messy, with some down 20% and others bouncing.
• Charts suggest a dangerous setup similar to 2000.
• The author protects by using a small bearish ETF (SOXS) and strict risk control.
