How to Do Supply Chain Analysis for Stocks Investing

Apple is the biggest public company in the world by market capitalization. In the first quarter of 2021, the company had a market capitalization of more than $2 trillion.

To put this into perspective, if it was a country, the company would be ranked at number 8 after the United States, China, Japan, Germany, UK, India, and France. Its GDP would be slightly lower than the GDP of Africa, which has a GDP of more than $1.5 trillion.

But in November 2018, Apple’s stock had a tough week. This is because of the company’s suppliers who reduced their guidance for the year.

It started with a company known as Lumentum, which supplies Apple with facial recognition technologies. It was then followed by a company known as Qorvo, which supplies Apple with networking products.

A reduction of guidance by Apple’s suppliers was a good indication that the company’s latest devices uptake was not as expected.

Traders usually pay close attention to the revenues and guidance of the companies that supply Apple with products. If their revenues and guidance rise, it is usually an indication that Apple will do well. This is because to most of these companies, Apple is their biggest customer.

 Six Fundamental Informations to Look at When invest in Stocks Companies

What is a supply chain?

Supply chain refers to a process in which an item moves from a raw material to a manufactured product. For example, to manufacture an iPhone, you need several things. For example, you need a lithium battery.

To come up with a battery, you need raw materials like lithium, aluminum, nickel, and sulfur. These minerals are mined around the world. An iPhone also has other parts like glass, chip, and cameras among others.

Therefore, to conduct a comprehensive supply chain analysis for the company, you need to identify these parts. You also need to know their manufacturers.

Why these informations are important for traders

As a stocks trader, it is very important for you to understand the supply chains for companies that you invest in. This is because by understanding how they are performing, you can easily predict how the companies you are following are doing.

For example, General Electric is one of the biggest suppliers of engines to Boeing. Therefore, if General Electric’s aviation business announces a slowdown in business, it means that Boeing has some problems as well.

Similarly, if companies like Intel and NVIDIA announce slow sales, hardware companies like Dell, Apple, and HP will be expected to go down.

Therefore, the role of supply chain in making investment decision is very important. This is because it has the ability of influencing the stock performance of other companies. A boost in sales in one supplier could mean more orders while a reduced supply could affect other companies.

In the past, we have seen share prices of companies fall or soar by association. For example, as mentioned above, Apple shares tend to react to the performance of some of its key suppliers like Corning, Samsung, Hon Hai Precision, and Broadcom, among others.

How to trade Supply Chains

To trade using this model, you need to understand a few things.

First, you need to understand the companies that supply the company that you invest in. You can gain this information by going through the annual reports of the companies.

You can also get this information from the business-related news websites like Bloomberg and Wall Street Journal. If you can afford paying a software provider like Bloomberg Terminal, you can get access to this information.

Raw materials and currencies

The supply chain is not only about companies. It is also about the raw materials and currencies.

For example, when the price of crude oil jumps, chances are that the stocks of oil exploring companies like ExxonMobil and Chevron will rise as well. Similarly, when the price of gold rises, that of gold mining companies will rise too.

On the other hand, when prices of raw materials rise, the result is that the margins of the companies will be squeezed.

For example, if the price of cotton rises, it will squeeze the margins of companies like Adidas leading to their stock price to decline. Therefore, as a trader, you should always pay a closer attention to these issues.

How to find supply chain data

Ideally, at the basic level, supply chain is a relatively simple process. For example, when trading in commodity-reliant companies, looking at their prices can help you predict where the shares will go.

For example, when commodity prices rise, some companies like Boeing and Caterpillar tends to be affected. On the other hand, the share prices of commodity miners usually rise.

However, looking at the supply chain of some companies can be difficult.

Fortunately, there are some companies – as stated above – like Yahoo Finance that have features to simplify the process. For example, in the chart below, we can see some of the biggest Apple suppliers and buyers.

Example of Apple’s Supply Chain Analysis


Conducting a supply chain analysis can be a helpful process for you as a day trader. Knowing the raw materials that go into a product and the top suppliers for a company can give you an edge in making good decisions.

However, this process does not always work since there are other things that move a company’s share price. For example, Apple’s suppliers may release strong earnings because of other external factors such as incorporating an acquired firm.

Therefore, you should use this process to complement your other analysis methods.
