How to Determine Point Value: Stock Indices (NAS100, SPX500, GER40)
Trading stock indices is often considered the "major league" of the financial markets. Indices like the Nasdaq 100 (NAS100), the S&P 500 (SPX500), and the DAX 40 (GER40) offer traders a way to speculate on the overall health of an entire economy or sector rather than a single company.
However, many traders who transition from Forex to Indices face a massive hurdle: The math of a "Point" is entirely different from the math of a "Pip."
If you treat a 10-point move on the Nasdaq the same way you treat a 10-pip move on EUR/USD, you are in for a shock. This guide provides a comprehensive breakdown of how to determine point values across the world's most popular indices, ensuring you never miscalculate your risk again.
1. Defining the Terms: Points vs. Pips
In Forex, we measure movement in pips (usually $0.0001$). In the world of indices, we measure movement in Points and Ticks.
This is the smallest whole unit move in the index price. For example, if the SPX500 moves from 5,000.00 to 5,001.00, that is a 1-point move.
This is the smallest possible price increment. Most indices move in decimals (0.10, 0.25, or 0.01).
Index Composition: Remember that an index is a weighted average. When you buy "1 lot" of the GER40, you are effectively buying a basket of 40 German companies.
2. NAS100 (Nasdaq 100) Point Value
The NAS100 is the "Tech Heavy" index. It is known for extreme volatility and massive daily ranges. Because the price of the Nasdaq is currently very high (often over 17,000), a "small" percentage move can result in hundreds of points.
Standard Contract Specifications
In most CFD (Contract for Difference) brokers, 1 Lot = 1 Contract.
| Lot Size | Units | Value per 1 Point Move | Value per 100 Point Move |
|---|---|---|---|
| 1.00 (Standard) | 1 | $1.00 | $100.00 |
| 0.10 (Mini) | 0.1 | $0.10 | $10.00 |
| 0.01 (Micro) | 0.01 | $0.01 | $1.00 |
Critical Note: Some brokers use a different contract size where 1 lot = $10 per point. Always check your broker's "Contract Specification" by right-clicking the symbol in Market Watch.
3. SPX500 (S&P 500) Point Value
The S&P 500 is the benchmark for the US economy. It is generally less volatile than the Nasdaq but requires a deep understanding of point value because its movements are more "expensive" per point on many platforms.
Table: SPX500 Point Value Breakdown
Commonly used CFD structure (1 lot = $1 per point)
| Change in Index Price | 1.00 Lot P/L | 0.10 Lot P/L | 0.01 Lot P/L |
|---|---|---|---|
| +1.00 Point | +$1.00 | +$0.10 | +$0.01 |
| +10.00 Points | +$10.00 | +$1.00 | +$0.10 |
| +50.00 Points | +$50.00 | +$5.00 | +$0.50 |
| -100.00 Points | -$100.00 | -$10.00 | -$1.00 |
4. GER40 (DAX 40) Point Value
The GER40 (formerly DAX 30) represents the 40 largest companies in Germany. Since this is a European index, the point value is originally calculated in Euros (€). If your account is in USD, your broker will convert this in real-time.
Table: GER40 Value (Assuming €1.00 per Point)
Note: Conversion to USD fluctuates based on the EUR/USD exchange rate.
| Lot Size | Value per Point (€) | Value per Point (USD approx.) | 50 Point Move (USD) |
|---|---|---|---|
| 1.00 | €1.00 | ~$1.08 | $54.00 |
| 0.10 | €0.10 | ~$0.11 | $5.50 |
| 0.01 | €0.01 | ~$0.01 | $0.50 |
Pro Tip: Keep an eye on the EUR/USD pair. A significant change in the exchange rate can slightly affect your GER40 P/L even if the index price remains the same.

| NAS100 | 0.01 | 15,000.00 | 16,000.00 | +1,000.00 | +$10.00 |
6. How to Avoid the "Contract Size Trap"
The biggest mistake index traders make is assuming every broker uses the same contract size.
Broker A
1 Lot of NAS100 = $1 per point.
Broker B
1 Lot of NAS100 = $10 per point.
Broker C
1 Lot of NAS100 = $100 per point (Future contracts).
How to verify your broker's math:
- 1 Open your MT4/MT5 platform.
- 2 Go to the Market Watch window.
- 3 Right-click on NAS100 (or US100).
- 4 Select Specification.
- 5 Look for Contract Size. If it says "1", then 1 lot = $1 per point. If it says "10", then 1 lot = $10 per point.
7. Volatility Check: Average Daily Range (ADR)
Indices move much further than currencies. While EUR/USD might move 70-100 pips a day, the NAS100 can easily move 200-400 points.
| Index | Average Daily Move (Points) | Dollar Impact (1 Lot) |
|---|---|---|
| NAS100 | 250 - 400 | $250 - $400 |
| SPX500 | 40 - 70 | $40 - $70 |
| GER40 | 150 - 250 | $160 - $270 |
8. Index Position Sizing for Risk Management
Because indices move fast, you must calculate your lot size before you enter. Here is a simple 3-step process.
Calculation: $50 / (50 х 1) = 1.00 Lot
9. Key Takeaways for Index Traders
- ✔ Whole Numbers Matter: Focus on the change in whole numbers, not the decimals (pipettes).
- ✔ Conversion Rates: If you trade the GER40 (Germany) or UK100 (UK) with a USD account, be aware that your profit will fluctuate slightly based on the exchange rate of the Euro or Pound.
- ✔ Leverage is High: Indices often require more margin than Forex. Always check your "Required Margin" before opening multiple positions.
- ✔ News Sensitivity: Indices are extremely sensitive to "Big Tech" earnings (for NAS100) and Central Bank interest rate decisions.
Final Summary Table
| Feature | NAS100 | SPX500 | GER40 |
|---|---|---|---|
| Main Driver | Technology Sector | Broad US Economy | German Manufacturing |
| Point Value (1 Lot) | $1.00 | $1.00 | €1.00 |
| Volatility Rank | 1 (Highest) | 3 (Lowest) | 2 (Medium) |
| Typical Spread | 1.0 - 2.0 Points | 0.4 - 0.6 Points | 0.5 - 1.5 Points |
Understanding how to determine point value for stock indices is the difference between a controlled trade and a blown account. Use these tables as a cheat sheet, and always verify your broker's specific contract sizes before clicking "Trade."
