What Are ETFs and Index Funds?
If you have ever heard someone say "the market is up today," they are usually referring to a stock market index like the S&P 500 or the Dow Jones. But what exactly are indices, and how can you trade them? This topic breaks down ETFs, index funds, and how you can access these markets through CFDs.
What Is a Stock Market Index?
A stock market index is a measurement of a section of the stock market. It tracks the performance of a specific group of stocks to represent the overall health of that market segment.
Major Global Indices
| Index | Country | What It Tracks | # of Stocks |
|---|---|---|---|
| S&P 500 | USA | 500 largest US companies | 500 |
| USTEC (NASDAQ-100) | USA | 100 largest non-financial NASDAQ companies | 100 |
| Dow Jones (DJIA) | USA | 30 large US blue-chip companies | 30 |
| FTSE 100 | UK | 100 largest London-listed companies | 100 |
| DAX 40 | Germany | 40 largest Frankfurt-listed companies | 40 |
| Nikkei 225 | Japan | 225 largest Tokyo-listed companies | 225 |
When you hear that the S&P 500 gained 1%, it means the weighted average of 500 major US stocks increased by 1%. It is a snapshot of overall market sentiment.
ETFs: Exchange-Traded Funds
An ETF is a fund that holds a basket of assets (stocks, bonds, commodities) and trades on a stock exchange just like a regular stock.
How ETFs Work
- A fund manager creates a basket of assets (e.g., all S&P 500 stocks)
- The ETF is listed on an exchange with a ticker symbol
- You buy and sell shares of the ETF throughout the day at market price
- The ETF price tracks the value of its underlying assets
Popular ETFs
| ETF | Ticker | What It Tracks |
|---|---|---|
| SPDR S&P 500 | SPY | S&P 500 index |
| Invesco QQQ | QQQ | NASDAQ-100 index |
| iShares MSCI Emerging | EEM | Emerging market stocks |
| SPDR Gold Shares | GLD | Gold price |
| Vanguard Total Bond | BND | US bond market |
ETF Advantages
- Diversification: One purchase gives you exposure to hundreds of stocks
- Low fees: Most index ETFs charge 0.03% - 0.20% per year
- Liquidity: Trade any time during market hours
- Transparency: Holdings are disclosed daily
Index Funds vs. ETFs vs. Mutual Funds
| Feature | ETF | Index Fund | Mutual Fund |
|---|---|---|---|
| Trades on exchange | Yes | No (end of day) | No (end of day) |
| Minimum investment | Price of 1 share | Often $1,000+ | Often $1,000+ |
| Expense ratio | Very low (0.03-0.20%) | Very low (0.03-0.20%) | Higher (0.50-2.00%) |
| Active management | Usually passive | Passive | Often active |
| Intraday trading | Yes | No | No |
| Tax efficiency | High | High | Lower |
For most beginners, ETFs and index funds that track broad market indices offer the best combination of diversification, low cost, and simplicity. They consistently outperform most actively managed funds over the long term.

Available Index CFDs on RoboForex
| Instrument | Based On | Typical Spread |
|---|---|---|

Example Trade
You believe tech stocks will rally this week. Instead of buying 100 different tech stocks, you:
- Open MT4 and select the USTEC (NASDAQ-100) CFD
- Buy 1 lot at 18,000
- Set stop loss at 17,900 (100 points risk)
- Set take profit at 18,200 (200 points reward)
- If USTEC reaches 18,200, you profit from the entire 200-point move
How Indices Are Calculated
There are two main methods:
Price-Weighted (e.g., Dow Jones)
- Stocks with higher share prices have more influence
- A $500 stock affects the index 10x more than a $50 stock
- This means price, not company size, determines weight
Market-Cap Weighted (e.g., S&P 500, NASDAQ-100)
- Stocks with larger market capitalizations have more influence
- Apple ($3T market cap) affects the S&P 500 far more than a smaller company
- This is considered a more representative method
Did You Know? The top 10 stocks in the S&P 500 (Apple, Microsoft, NVIDIA, etc.) make up roughly 30% of the entire index. So when you hear the S&P 500 moved, it often reflects what a handful of mega-cap tech stocks did.
