Net change represents the difference between an asset’s current price and its previous closing price, typically expressed in absolute terms (points or currency units) rather than percentages. This basic but essential metric helps traders quickly assess daily price movements and market momentum across different instruments and timeframes.

Net change calculations provide the foundation for more complex analysis including volatility measures, trend analysis, and performance comparisons. Understanding net change helps traders assess market activity levels and identify instruments experiencing significant price movements. This metric is particularly useful for screening markets and identifying trading opportunities.

Real-world example: Apple stock shows a net change of +$8.50 from yesterday’s close of $145.00 to today’s close of $153.50, indicating strong bullish momentum that might attract momentum traders and technical analysts.
