Today's Lesson: Stochastic %K
Greetings! Welcome to the Weekend Stock Market School. Today, we'll learn how to measure the market's "breath". This is a great tool that helps you understand how fast the market is moving and where the price stands within the last 14 days.
1. What is it? (With a Simple Analogy)
Imagine there's an exam at school. There are 14 minutes left until the exam ends. You've opened your exam paper and can see your current answer. Stochastic %K tells you how many "wrong" or "right" answers you've given to the questions on this paper. In other words, where does the current price stand within its range over the last 14 days? It calculates this as a percentage.
2. Why is it important?
What does this information provide for the investor? The Stochastic %K captures moments when the price is "stuck" or "has moved too far". The market generally revolves around "fair value". This oscillator shows us the probability of the price returning when it moves far from this balance (when it's too expensive or too cheap). This is critical for risk management and position-taking decisions.
3. How to Read / Use?
Stochastic %K generally moves between 0% and 100%. The most commonly used thresholds are 20% and80%tir.
-
% Above 80 (Overbought): The price has risen very quickly over the last 14 days. This is a "warning" signal. Since the market is moving very fast, a correction (dip) is generally expected.
-
% Below 20 (Oversold): The price has fallen very quickly over the last 14 days. This is an "opportunity" signal. Since the market is moving very fast, a rise (wave) is generally expected.
Usage Logic: % Be cautious when it goes above 80, and try your luck when it goes below 20%.
4. Real Example
When we look at today's data, the general market atmosphere seems a bit "stuck". Let's look at one of the most active stocks:
-
DSTKF: The last closing price was 1.984.00 TL. The daily movement was quite sharp with a 9.98% decrease. The Stochastic %K value is likely well below 20 (in the overbought zone). This means the price has fallen very rapidly.
-
GUBRF: The last closing price was 443.50 TL. The daily movement was positive with a 3.32% increase. The Stochastic %K value is likely above 80 (in the oversold zone). This indicates that the price has been strong recently.
5. Common Mistakes
- Relying on a Single Indicator: If you only look at the %K chart and buy because it's "oversold", you can suffer significant losses if the trend is still downward. Please use it in conjunction with %D (smoothing line).
- Ignoring the Trend Effect: While the 80 and 20 levels are used more frequently in a sideways trend, it's normal for %K to go above 80 in a strong uptrend. Don't overlook the trend.
- Lagging Nature: Since Stochastic is an oscillator, when the price reaches its peak, %K may already be above 80. That's why don't follow the "last point", follow the "journey".
6. Mini Test
Shall we take the test? I've hidden the answers below.
- When the Stochastic %K value goes above 80, what is typically expected in the market?
- % What is expected when it goes below 20?
- The DSTKF stock had a 9.98% drop in daily movement. What does this situation typically show on the %K chart?
Answer Key:
1. Overbought and the possibility of a price dip.
2. Oversold and the possibility of a price rise.
3. Being well below 20 (being in the oversold zone).
7. Summary
-
Stochastic %K shows the position of the price within the last 14 days.
-
80% = Overbought (be careful).
-
20% = Oversold (an opportunity).
-
Consider the direction of the trend.
-
Do not validate with this indicator alone, but also with other technical indicators.
