Get to know the NASDAQ 100 and Dow Jones Industrial Average

Get to know the NASDAQ 100 and Dow Jones Industrial Average

Welcome to another trading lesson! Today we'll venture into the exciting realm of index trading, featuring two of today's leading stock market indices: the NASDAQ 100 and the Dow Jones (short for Dow Jones Industrial Average). You've probably heard of both of them since the beginning of your trading journey, but let's explore them in depth to find out why people all around the globe track their performance so closely.

One quick note before we start: at iFOREX, you have the opportunity to invest in CFD instruments that track the price performance of both the NASDAQ and Dow Jones.

Confused? Don't worry, we'll explain. Let's go.

What are market indices?

There's no point in diving straight into how market indices work unless we first know what we're talking about. However, if you're already familiar with market indices, you can skip ahead.

Definition: a market index measures a particular part of the stock market, and its price is determined by the prices of several stocks contained therein. This gives investors the opportunity to invest in a collection of instruments (or a basket, if you need a visual). For example, rather than choosing one or two companies to invest in, such as Apple or Google, choosing an index would allow you to invest in a few shares at a time, thereby investing in a portion of the market.

There are even some indices that measure the performance of a particular industry, a country's economy, and even investor sentiment.

Wait: have you had a chance to read about index trading? If not, what better time than now?

Dow Jones Industrial Average

As one of the most popular market indices in the world, the Dow Jones goes by many names. It's full name is the Dow Jones Industrial Average, but it's also commonly called the Dow Jones, Dow 30, DJIA, or just the Dow. Chances are you've heard all of them during a single financial news broadcast, as traders from all over the world frequently check in to see how the Dow Jones is performing.

Background on the Dow Jones

The name comes from Charles Dow, an editor of the Wall Street Journal who first established his namesake index back on May 26th, 1896. However, the Dow Jones Industrial Average is only the second oldest index in the US. The first, also created by Charles Dow, was the Dow Jones Transportation Average.

What are the companies that comprise the Dow Jones?

Just like you've no doubt heard of the Dow Jones, there's little doubt you're also quite familiar with the companies included in it, a list of 30 large, publicly-owned companies like Coca-Cola, Disney, Apple, Boeing, Nike, McDonald's, and IBM. The "industrial average" part is actually a scaled average, calculated as the sum of every component price that's then divided by a divisor, which alters when any of the component stocks experiences a stock split or dividend. Sounds confusing, we know, but rest assured you'll never have to worry about doing this calculation yourself.

Where does the 'industrial' part come from?

The answer dates back to when it was created, as many of the companies included therein were frontrunners in the US industrialization era.

Which factors can affect Dow Jones prices?

Here are a few examples of the major factors that can impact the Dow Jones index prices:

  • Major economic reports
  • Fed decisions and statements
  • Politics and geopolitics
  • International tensions and conflicts
  • Extreme weather
  • Natural disasters

Investing in the US 30 at iFOREX

Another index? Not quite. The US 30 is a financial instrument that tracks the performance of the Dow Jones Industrial Average's futures index, which gives traders the chance to invest using CFDs while employing market leverage.

Contracts for Difference

Need a quick recap of how CFDs work? No problem. Contracts for Difference allow traders to invest in the price movements of financial instruments (such as indices, shares, commodities, foreign currencies, ETFs and cryptocurrencies) without having to purchase the underlying asset. Need an example? Let's say you'd like to invest in gold CFDs. Each contract represents the price of one ounce of gold. For oil, it's the price of one barrel. And for indices like the US 30 or US Tech 100, each contract represents the current price of the index.

The NASDAQ-100

Almost as popular as the Dow Jones, the NASDAQ-100 is definitely one of the most prominent stock indices in the world. Let's see why.

Background on the NASDAQ-100

The NASDAQ-100 is quite young when compared with the Dow Jones, created by the NASDAQ on January 31st of 1985 as a way to promote itself alongside the older New York Stock Exchange. And what's better than one new index? Two indices! One of which is the NASDAQ-100 index, consisting of companies in the technology, industrial, telecommunication, biotechnology, transportation, media, service, retail and healthcare sectors. Among companies included are Amazon, Netflix, Alphabet (Google's parent company), Tesla and Apple.

Wait, you said there were two indices created. Indeed! The second index was the NASDAQ Financial-100, which mostly includes companies in the banking and financial sector.

Fun fact: even though it's the NASDAQ-100, the number of components can fluctuate, since several of them feature multiple share classes.

How is the NASDAQ calculated?

The simple answer: the NASDAQ is a modified capitalization-weighted index. Now, for the explanation: all that it means is that the weight of the stocks contained in the index is based on their market capitalizations, and is subject to several regulations to moderate the influence of the larger components. This also allows larger companies such as Apple to gain a larger impact on the value of the NASDAQ.

Does the NASDAQ-100 differ from the NASDAQ composite index?

Good question, and one with an actual simple answer. The NASDAQ composite index is the term that applies to all the companies listed on the NASDAQ stock exchange, amounting to over 3,000, while the NASDAQ-100 refers to a specific sector, with significantly less components.

Which factors can affect the NASDAQ-100 prices?

Here are a few examples of the major factors that can affect the NASDAQ-100:

  • Major economic reports
  • Fed decisions and statements
  • Politics and geopolitics
  • International conflicts and tensions
  • Changes in the larger companies included in the index
  • Changes in the tech industry

Investing in the US Tech 100 at iFOREX

Just like we said above, at iFOREX you can invest in CFDs of the US Tech 100 index, which is a financial instrument that tracks the performance of the NASDAQ-100 futures index.

Does the NASDAQ-100 differ from the Dow Jones?

Two indices, both important, but with very different functions. Here are two significant differences between the two:

  1. The NASDAQ index is comprised of American companies as well as foreign
  2. The NASDAQ doesn't include any companies in the banking sector

Ready to open your first index trading CFD deal?
