Learn MoomooHow to read Industry Chain in Moomoo — map an industry from upstream to downstream (screenshots of every screen)
Industry Chain shows who supplies what to whom in an industry, from raw material to final product. This tutorial uses the semiconductor chain to show you how to read the map, find Bursa companies at each stage, and avoid misreading it.
Every phone in your pocket has a chip inside it. But that chip wasn’t made by just one company.
One company sells the software used to design the chip. Another makes the chemicals. Another builds the factory machines. Then there are companies that design the chip, companies that fabricate it, companies that package and test it, and finally companies that put that chip into a phone, a car, or a computer.
This chain of companies is called an industry chain. The earliest stage (materials and equipment) is called upstream. The middle stage (manufacturing) is called midstream. The final stage (the product that reaches the end user) is called downstream.
Moomoo has a feature called Industry Chain that draws this out as a map, and every box on that map can be tapped to see a list of companies. What’s especially useful for Malaysian investors is that the list can be switched to show Bursa stocks.
All screenshots were taken on 17 September 2026. Prices and company lists in your app may be different. The company names in this tutorial are examples pulled from Moomoo’s map, not a recommendation to buy.
Part 1 — Find Industry Chain
Markets → US → scroll to Industry Chain
Tap the Markets tab at the bottom bar and choose US.
Scroll all the way down past Heat Map, Market Monitor and All Stocks. You’ll find the Industry Chain section with two sample chains, AI and Commercial Space.
Tap the › arrow at the far right of the title to open the full list.
Pick a chain
This list has plenty of chains, including AI, Semiconductors, Humanoid Robot, Quantum Computing, Memory Chips, Electric Vehicles, and more. Below each name are two big-name tickers from that chain.
The lightbulb icon at the top right opens Moomoo’s own guide titled How to Use Industrial Chain, complete with a short video.
Let’s open Semiconductors. This chain is the closest one to Malaysia, since Malaysia is one of the world’s biggest hubs for chip packaging and testing.
Part 2 — Reading the semiconductor chain map
Top of the page: chain size and the first stage
At the top of the map there are two numbers:
- Market Cap (USD) 36.85T — the total Market capA company's total value in the market.See it in the glossary → of every company in this chain, roughly USD36.85 trillion
- Components 260 — the number of companies Moomoo has placed in this chain
Below that is a short description of the industry. Then the map itself begins.
The map reads top to bottom. The light gray boxes on the left are the main stages. The darker boxes on the right are the sub-categories of each stage. The first stage is Design Tools, which covers design licensing (IP Licensing) and chip design software (EDA).
Upstream: materials and equipment
After Design Tools, the map moves down to four more upstream stages:
| Stage | Sub-category examples |
|---|---|
| Materials/Chemicals | Polysilicon, specialty gases, photoresist, packaging materials |
| Wafer Fabrication Equipment | Lithography, etching, deposition, inspection machines |
| Packaging Equipment | Dicing saws, die bonders, wire bonders |
| Testing Equipment | Test machines, probe stations, sorters |
Every company in this stage sells to chipmakers. That means when factories around the world want to add capacity, these upstream companies are usually among the first to see orders come in.
Midstream and downstream: from chip design to final product
The bottom half of the map covers the manufacturing and usage stages:
- Chip Design — designing chips such as integrated circuits, sensors, and optoelectronic components
- Chip Fabrication — manufacturing chips onto wafers
- Packaging and Testing — packaging chips and testing them before shipping
- Applications — products that use chips: computers, consumer electronics, communications, automotive, security, and defense
The Applications stage is downstream, meaning the companies that buy chips to put into their own products.
Tap ⊕ to expand a box
Some boxes have a small ⊕ mark next to them. That mark means the box has further sub-categories.
For example, tap ⊕ next to Integrated Circuit. Four new boxes appear on the right: Analog Chips, Logic Chips, Microprocessors, and Memory Chips. The mark turns into a ⊖, and you can tap it again to collapse it back.
When new boxes run off the edge of the screen, swipe the map left to see the part that’s cut off.
Part 3 — Find companies in each box
Tap a box for the company list
Tap the Packaging and Testing box. A list slides up from the bottom with company names, prices, and the day’s percentage change.
By default, this list shows the US market. For Packaging and Testing, there’s only one American company on the list, AMKR (Amkor Technology).
Notice the US ▾ button at the top right of the list. This is the button that matters most for Malaysian investors.
Switch to MY — Bursa companies in the same stage
Tap US ▾. A list of markets appears: All, US, MY, SG, HK, CN, JP, CA, and more.
Pick MY. The list immediately switches to Bursa Malaysia companies in the chip packaging and testing stage:
| Code | Name | Price (RM) | Change |
|---|---|---|---|
| 0166 | INARI | 2.520 | +0.00% |
| 3867 | MPI | 39.500 | −0.50% |
| 5005 | UNISEM | 4.110 | +0.24% |
| 0146 | JFTECH | 0.620 | −1.59% |
| 0278 | EDELTEQ | 0.320 | −1.54% |
This is the most practical use of this feature. When you read news about global chip demand, you can immediately see which Bursa companies sit in the same stage of that chain.
Tap the box's title for the full page
In that list, tap the Packaging and Testing › title at the top. The full page for that stage opens.
This page has a short description of the stage. For example, packaging and testing is also known as assembly and test, and it bridges processed wafers with finished chips.
Below that is the parent chain (Semiconductors) and a Components list that can also be switched between markets.
Not every box has a Malaysian company
Now try a different chain. Go back to the list and open AI.
The AI chain is arranged in three layers: Infrastructure Layer (computing power, data services, energy facilities), Algorithm Layer (AI models), and Application Layer (apps that use AI). It’s a bigger chain than semiconductors, at USD50.26 trillion with 333 companies.
Tap the Data Center and Service box. The US market shows names like EQIX, DLR, GOOGL, MSFT, AMZN, and ORCL. But switch it to MY, and the list shows No Data.
“No Data” doesn’t mean no Malaysian company is involved in data centers. It just means Moomoo hasn’t placed any Bursa company in that box yet. This map is useful, but it’s not complete.
Part 4 — How to use this map correctly
Use it to understand the impact of news
Industry Chain is most useful when there’s news that hits a specific stage. For example, if the price of a chemical used in chip fabs rises, you can look at the map and ask: who sells that material, who has to pay more for it, and who downstream might feel the effect later.
The map doesn’t give you the answer. But it tells you the question worth asking and the company names worth researching.
One company can sit in more than one stage
Big companies usually run several kinds of business. For example, MSFT shows up as a sample ticker in both the AI chain and the Semiconductors chain. So don’t assume a company in one box only does that one thing.
To find out how much of a company’s revenue actually comes from one stage, open that stock’s page and go to Company → Revenue Breakdown.
Combine it with other features
- Investment Themes — groups stocks by story, for example Penang AI or Johor
- Compare — compares companies in the same box side by side, for example INARI against UNISEM
- Moomoo AI — ask what a company’s business actually is in plain language, then check its sources
A company’s position on the map doesn’t tell you whether it’s profitable, heavily indebted, or expensively priced. Every name in this tutorial is an example pulled from Moomoo’s map. This content isn’t financial advice.
Common mistakes when using Industry Chain
1. Assuming the map is complete. A box showing “No Data” for MY doesn’t mean there’s no Malaysian company in that field. It just hasn’t been added to the map yet.
2. Forgetting to switch markets. The list starts on the US market. A lot of people don’t notice the US ▾ button and miss the list of Bursa companies entirely.
3. Assuming upstream and downstream companies move together. When demand shifts, the impact on each stage can arrive at a different time and a different size.
4. Using the map as a buy signal. The map shows the relationship between companies. It doesn’t judge whether a stock’s price is reasonable.
Frequently asked questions
Is Industry Chain available for the Malaysian market? The Industry Chain section lives inside Markets → US. That said, the company list inside each box can be switched to MY using the market button at the top right of the list.
What do upstream, midstream and downstream mean? Upstream means suppliers of materials, tools and equipment. Midstream means manufacturers of the core product. Downstream means companies that use that product in goods that reach the end consumer.
Why do some boxes get cut off at the edge of the screen? The map is wider than a phone screen. Swipe the map left to see the part on the right.
How do I know if a company truly depends on one stage? Open the stock’s page, go to the Company tab, and check Revenue Breakdown. That section shows the revenue split by business line.
What’s the difference between Industry Chain and Investment Themes? Investment Themes groups stocks into one list by story. Industry Chain arranges companies by stage in a supply chain, so you can see who supplies whom.
