The Know Sure Thing (KST) is a momentum oscillator developed by Martin Pring to make rate-of-change readings easier for traders to interpret. This comprehensive guide delves into the intricacies of the KST, its calculation methods, practical applications, and historical context.
Understanding the Know Sure Thing (KST)
The Know Sure Thing (KST) is designed to identify the overall direction and strength of a stock’s momentum. The KST combines four different smoothed rate-of-change calculations into a single momentum oscillator, effectively smoothing out the volatility and providing a clearer picture of the prevailing trend.
- Definition: The KST is a momentum oscillator that aids traders in interpreting rate-of-change readings by smoothing data and combining multiple timeframes.
- Purpose: To help traders identify the direction and sustainability of a stock’s momentum.
Calculation of KST
The KST is calculated using the following formula:
Where:
- \( RCMA \) represents Rate-of-Change Moving Averages.
- \( w \) represents the weighting of each period.
Steps in Calculation
- Calculate Rate-of-Change (ROC): Determine the ROC for four different periods (e.g., 10, 15, 20, and 30 days).
- Smooth the ROCs: Apply a moving average to each ROC (e.g., simple or exponential).
- Weight the Moving Averages: Assign different weights to each smoothed ROC (often increasing with the length of the period).
- Sum the Weighted ROCs: Combine the weighted moving averages to form the KST value.
Practical Calculation Example
Consider a stock with the following closing prices over the last 30 days:
- Calculate the 10-day, 15-day, 20-day, and 30-day ROCs.
- Smooth these ROCs with a 10-day moving average.
- Assign weights of 1, 2, 3, and 4 respectively.
- Compute the final KST by summing the weighted averages.
Hisorical data, specific prices, and the resultant KST values will offer traders a valuable momentum indicator.
Applications of KST
Usage in Trading
Traders use the KST oscillator to:
- Identify potential buy or sell signals.
- Confirm existing trends.
- Detect divergence between the KST and price movements, indicating possible reversals.
Example in Practice
A trader may observe that the KST has crossed above the zero line, signaling a buy opportunity. Conversely, a drop below zero might indicate a selling point.
Historical Context and Development
Martin Pring introduced the KST to address the limitations of traditional momentum indicators. By blending multiple timeframes, the KST aims to reduce noise and offer a broader view of market momentum.
Comparisons and Related Terms
- MACD (Moving Average Convergence Divergence): Like KST, MACD is used to identify momentum changes, but it focuses on the relationship between two moving averages of a stock’s price.
- RSI (Relative Strength Index): Measures the speed and change of price movements on a scale of 0 to 100, often used in conjunction to validate KST signals.

Summary
The Know Sure Thing (KST) is a dynamic momentum oscillator that assists traders in interpreting rate-of-change readings by combining multiple timeframes and smoothing methods. Developed by Martin Pring, the KST offers a clearer view of market momentum, making it an essential tool for technical analysis. Whether used to identify buy/sell signals, confirm trends, or detect divergences, the KST remains a versatile and powerful indicator in the trading world.
