What Is Know Sure Thing (KST)?

The Know Sure Thing (KST) is a momentum oscillator used in technical analysis to interpret rate-of-change readings across various timeframes, helping traders identify trend shifts. Developed by Martin Pring, the KST indicator combines several smoothed Rate of Change values into a single line, aiming to provide a clearer signal of market momentum. It falls under the broader financial category of technical analysis, a discipline focused on forecasting future financial price movements based on historical price action and volume. The Know Sure Thing indicator helps market participants gauge the strength of price movements and potential reversals.

History and Origin

The Know Sure Thing (KST) indicator was developed by Martin Pring, a renowned technical analyst and author. Pring introduced the KST in 1992 in Stocks & Commodities magazine, aiming to simplify the interpretation of multiple rate-of-change readings by combining them into one comprehensive momentum oscillator. His work sought to provide a smoother, more reliable signal for identifying shifts in market momentum and trends.⁶ Martin Pring has contributed extensively to the field of technical analysis through his writings and research.⁵

Key Takeaways

• The Know Sure Thing (KST) is a momentum oscillator that simplifies the analysis of price rate-of-change across different timeframes.
• It combines and weights four different smoothed rate-of-change values into a single line.
• Traders often use KST to identify trend direction, potential reversals, and divergence.
• Trading signals are typically generated through crossovers with a signal line or the zero line.
• Like all indicators in technical analysis, KST is most effective when used in conjunction with other analytical tools and market context.

Formula and Calculation

The Know Sure Thing (KST) is calculated by taking the Simple Moving Average (SMA) of four different Rate of Change (ROC) periods, applying specific weighting factors, and then summing them. A 9-period SMA of the resulting KST line typically serves as the signal line.

The formula for the Know Sure Thing (KST) is as follows:

Where:

• ROC(Close, N): Rate of Change for the closing price over N periods.
• SMA(N): Simple Moving Average over N periods.
• RCMA1, RCMA2, RCMA3, RCMA4: Represent the smoothed Rate of Change for different periods, each with its own Moving Average smoothing.
• The default parameters for the rate-of-change periods are 10, 15, 20, and 30, with smoothing periods of 10, 10, 10, and 15 respectively.⁴ The weighting factors (1, 2, 3, 4) give more significance to longer-term rate-of-change components.

Interpreting the Know Sure Thing (KST)

The Know Sure Thing (KST) fluctuates around a zero line, similar to other unbound momentum oscillators. The primary interpretations of KST involve its relationship to its signal line, its position relative to the zero line, and the presence of divergence with price.

• Signal Line Crossovers: A common trading signal is generated when the KST line crosses its signal line. A bullish signal occurs when the KST crosses above its signal line, suggesting increasing upward momentum. Conversely, a bearish signal is generated when the KST crosses below its signal line, indicating downward momentum.
• Zero Line Crossovers: A cross above the zero line suggests positive momentum and possibly a bullish trend, while a cross below indicates negative momentum and potentially a bearish trend.
• Divergence: Divergence between the KST and price can indicate potential trend reversals. For example, if price makes a higher high but KST makes a lower high (bearish divergence), it could suggest that the upward momentum is weakening, signaling a potential reversal. The opposite (bullish divergence) can occur when price makes a lower low but KST makes a higher low.³
• Trend Line Breaks: Martin Pring also suggested applying trend lines directly to the KST indicator, with breaks of these trend lines reinforcing signal line crossovers or providing early indications of shifts.

Unlike bound oscillators such as the Relative Strength Index (RSI), the Know Sure Thing (KST) does not have fixed upper and lower bounds, meaning it is not designed to identify overbought or oversold conditions directly.

Hypothetical Example

Consider a hypothetical stock, ABC Corp., with the following weekly closing prices over several weeks. To calculate the Know Sure Thing (KST) for ABC Corp., a trader would first determine the weekly Rate of Change (ROC) for 10, 15, 20, and 30 periods.

Let's simplify and illustrate a step in the process:

Assume the 10-period ROC for ABC Corp. is 5%, and its 10-period Simple Moving Average (SMA) is 4.5%. This value, 4.5%, would be RCMA1.

Next, assume the 15-period ROC is 8%, and its 10-period SMA is 7.2%. This would be RCMA2.

Similarly, RCMA3 and RCMA4 would be calculated.

For example, if the calculated smoothed Rate of Change values are:

• RCMA1 = 4.5
• RCMA2 = 7.2
• RCMA3 = 6.0
• RCMA4 = 9.5

The KST value would be:

This KST value would then be plotted. A 9-period Exponential Moving Average (or Simple Moving Average, depending on the specific implementation) of these KST values would then form the signal line, providing crucial points for analysis as the KST crosses above or below it.

Practical Applications

The Know Sure Thing (KST) indicator is widely used by traders and analysts as part of their broader technical analysis framework. Its primary application lies in confirming the direction and strength of price trends, as well as identifying potential turning points in various financial markets, including equities, commodities, and foreign exchange.

• Trend Confirmation: When KST rises above its signal line and/or the zero line, it can confirm an uptrend, suggesting that positive momentum is building. Conversely, a decline below these levels can confirm a downtrend.
• Entry and Exit Points: Crossovers between the KST line and its signal line are often used to generate buy or sell signals. A bullish crossover might suggest an entry point for a long trade, while a bearish crossover could indicate an exit point or a signal for a short position.
• Combining with Other Tools: Many traders combine the KST with other chart patterns and indicators, such as volume analysis or support and resistance levels, to validate signals and reduce false positives. Financial professionals frequently emphasize the importance of using multiple analytical techniques to make informed trading decisions.²

Limitations and Criticisms

While the Know Sure Thing (KST) can be a valuable tool for assessing momentum, it has limitations, as do all technical indicators.

• Lagging Indicator: Like most indicators derived from past price data, the KST is a lagging indicator. It reflects what has already occurred and may not always provide timely signals, especially in fast-moving or choppy markets.
• False Signals: In highly volatile or range-bound markets, the KST can generate false or whipsaw signals, leading to premature entries or exits. Relying solely on KST signals without considering overall market context or other forms of analysis can result in suboptimal trading decisions.
• Not for Overbought/Oversold: As an unbound oscillator, KST does not provide defined overbought or oversold levels, unlike indicators such as the Relative Strength Index (RSI). Its values can theoretically range indefinitely, making it unsuitable for identifying extreme price conditions in that specific manner.
• Parameter Sensitivity: The effectiveness of the Know Sure Thing (KST) can depend on the parameters chosen for its calculation (the periods for ROC and smoothing moving averages). Different settings may yield different signals, requiring careful backtesting and optimization for specific assets or timeframes. Ongoing academic research in finance often explores the nuanced impacts of various financial models and indicators, emphasizing that their applicability can vary significantly across different market conditions and asset classes.¹

Therefore, financial professionals generally recommend that the KST be used as part of a comprehensive trading strategy rather than as a standalone decision-making tool.

Know Sure Thing (KST) vs. Moving Average Convergence Divergence (MACD)

The Know Sure Thing (KST) and the Moving Average Convergence Divergence (MACD) are both popular momentum oscillators used in technical analysis, but they differ in their construction and emphasis.

While both indicators aim to gauge momentum and identify potential trend changes, the KST's strength lies in its multi-timeframe approach, which helps to smooth out short-term fluctuations and potentially provide a clearer, more confirmed view of momentum. The MACD, on the other hand, is known for its simplicity and direct representation of the convergence and divergence of moving averages, often highlighting changes in the speed and strength of price trends. Both are valuable tools, and traders may use one over the other or combine them based on their analytical preferences and market conditions.
