Price Action (8/12): Premium, Discount, and 50% Equilibrium – Where to Look for "Cheap" Entries in a Trend?

How many times have you jumped onto a moving train that seemed unstoppable, only for the price to turn around and move against you? The feeling that you "bought expensively" is one of the most common sources of frustration. Markets operate on a simple yet often overlooked logic of supply and demand, which manifests in a constant search for equilibrium.

The Story of the "Fair" Price and Why It Matters

Imagine you are a fruit trader at a market. In the morning, you buy apples for 10 Kč/kg. During the day, demand rises and the price shoots up to 20 Kč/kg. Many people would want to buy at that moment because they see growth. But you, as an experienced trader, know that selling at 20 Kč/kg is advantageous, while buying at 20 Kč/kg is risky. Why? Because the average price at which apples traded today is somewhere in the middle – let's say 15 Kč/kg. If you buy at 20 Kč/kg, you're buying at a "premium" (above average price) and risk the price returning to the "fair" value or even dropping into a "discount" (below average price).

It's similar in financial markets. Institutional players who move the market don't think in terms of "buy at any cost." Their goal is to maximize profit and minimize risk, which means buying "cheap" and selling "expensive." And defining what "cheap" and "expensive" means is crucial. Within a given price range (e.g., daily, weekly, or after a significant move), there is a point of equilibrium, often found at 50% of this range. Everything above this point is premium (relatively expensive), and everything below it is discount (relatively cheap).

Statistics and Expected Value: Why Discount Increases the Probability of Success

Imagine you have a slightly biased coin. Instead of 50:50, heads comes up 60% of the time. If you're betting on heads, you'd want to bet as much as possible when you can, right? Similarly, in markets, if you identify a strong upward trend, it is statistically more advantageous to look for buying opportunities in the "discount" of that move. Why?

Long-term data and simulations show that entries from the discount within a strong trend have a higher expected value (EV). For example, if in a rising trend you buy a stock that has just returned to the discount (fallen below 50% of its last significant upward move), you have a higher probability that the trend will continue and the price will return to the premium than if you buy in the premium. Roughly, if the average success rate of trades in the trend from the premium is around 40–45%, from the discount it can increase to 55–60%, with the same risk-reward ratio. This means that out of 100 trades, you would have more profitable trades, even though each individual trade is not guaranteed.

Practical Framework: How to Identify Premium, Discount, and Equilibrium

Let's look at a specific example. Stock XYZ recently moved from a price of 100 Kč to 120 Kč, representing a total range of 20 Kč. How do we determine the key zones?

1. Identify the significant price move: It's not about every small move, but a clearly defined "swing" from a local bottom to a local top (or vice versa). In our case, 100 Kč (bottom) -> 120 Kč (top).
2. Calculate the range: 120 Kč - 100 Kč = 20 Kč.
3. Determine the equilibrium (fair price): This is the midpoint of this range. 100 Kč + (20 Kč / 2) = 110 Kč. The price of 110 Kč is our 50% point.
4. Define the Premium zone: Any price above 110 Kč (up to 120 Kč) is considered premium. Here, in a rising trend, you would rather look for selling opportunities (if speculating on a correction) or avoid buying.
5. Define the Discount zone: Any price below 110 Kč (down to 100 Kč) is considered a discount. Here, in a rising trend, you would look for buying opportunities.

Example of use: If stock XYZ, after reaching 120 Kč, starts to fall and returns to 108 Kč, it is in the discount zone (below 110 Kč). If the overall trend is still upward, this is a "cheap" price for institutional players to buy again, rather than buying at 118 Kč (in the premium). This increases the probability that the price will bounce from 108 Kč and continue to rise.

Common Mistake: Absolute Perception Without Context

The biggest mistake is to take the concept of premium and discount absolutely, without regard to the broader context. The price of 108 Kč may be a "discount" within the last move of 100–120 Kč, but if we look at a longer time frame, this price may still be in the premium relative to the entire monthly or yearly range. It is always crucial to:

* Trend: Trade in the direction of the dominant trend. In a rising trend, look for buys in the discount. In a falling trend, look for sells in the premium.
* Time frame: Define the range for premium/discount on the time frame you are trading. A swing trader on a daily chart will perceive a different range than an intraday trader on a 15-minute chart.

When does it fail? The concept of premium/discount is a tool for reading the chart and increasing probability, not a certainty. It fails when the overall trend changes, when unexpected news comes, or when the market is in consolidation without a clear direction. In such cases, the price can move up and down through the equilibrium without apparent respect for the zones.

QMA Twist: Filtering Opportunities with Precision

Manually calculating ranges and 50% points on each chart is time-consuming. At QMA Brain, we focus on streamlining this process. Our tools can automatically identify significant price ranges and calculate key levels of premium, discount, and equilibrium for different time frames.

In QMA: You can use our Pattern Screener, which filters stocks that are currently in the discount zone after a strong impulsive move within a defined trend. This allows you to focus on the best probability opportunities without having to manually search through hundreds of charts.

Takeaways

1. Always define the range: Before entering a trade, determine the last significant price move and its 50% point (equilibrium).
2. Buy in the discount, sell in the premium: In a rising trend, look for buying opportunities below 50% of the range. In a falling trend, look for selling opportunities above 50% of the range.
3. Respect the trend and time frame: Premium/discount is a relative concept. Always perceive it in the context of the broader trend and your trading time frame.
4. Use stop-alerts: Even when entering from the discount, the market can turn. Always have a stop-alert ready to protect your capital if the probability edge does not materialize.

In Layman's Terms

Imagine you're going to buy a used car. The seller offers it for 200,000 Kč. But you know that similar models have been selling in recent weeks in the range of 150,000 Kč to 250,000 Kč. Equilibrium (balance) in this case is 200,000 Kč (the middle of the range). If the seller insists on 240,000 Kč, he is selling at a premium – it's relatively expensive. But if he needs to sell quickly and offers it to you for 160,000 Kč, he is selling at a discount – it's relatively cheap. For you, as a buyer, it's more advantageous to buy the car at a discount because you have a better chance of selling it later for a "fair" price (200,000 Kč) or even at a profit. In markets, it's the same: institutions want to "buy cheap" (in the discount) and "sell expensive" (in the premium), and we can try to synchronize with them.
