Prospect Theory, introduced by Kahnemann and Tversky in 1979, stands as a foundational concept in behavioral finance. Its significance was underscored by Kahnemann’s Nobel Prize in Economics in 2002.

What is Prospect Theory, and how does it detrimentally impact traders? This theory elucidates a fundamental trading error pervasive among traders. Let’s dissect it step by step.

Firstly, let’s comprehend Prospect Theory and examine illustrative examples for better comprehension. Secondly, let’s delve into how it adversely affects traders. Finally, let’s outline countermeasures traders can employ to enhance their trading performance. Regardless of whether you trade Crypto, Forex, stocks, or Futures, Prospect Theory’s general behavioral tendencies are relevant to any market.

Prospect Theory: What does it say?

At its core, Prospect Theory describes how humans asymmetrically assess potential losses and gains. As Kahnemann and Tversky stated in 1979, ‘in human decision-making, losses loom larger than gains.’ If you’re finding this concept too theoretical, we will take you on a journey through a real-life experiment that brings Prospect Theory to life.

Now what if the scenario is reversed:

Interestingly, when faced with the choice between A) and B), a whopping 92% opted for B), prioritizing the avoidance of losses. However, in the case of C) versus D), only a mere 20% chose D), showcasing a reluctance to gamble for potential gains (despite B & D offering similar risk/likelihood prospects).

This experiment underscores a fascinating human trait: a propensity to shun risk when potential gains are at stake, yet display a greater willingness to take chances to avert losses (a phenomenon known as loss aversion). This core principle sheds light on a crucial aspect: while individuals are typically risk-averse when it comes to gains, they’re more inclined to embrace risk when it comes to mitigating losses. And this insight holds significant implications, even within the intricate realm of trading.

Exploring the Application of Prospect Theory in Trading

Before diving into the application of Prospect Theory in trading, it’s essential to note two key aspects regarding behavioral biases in trading:

First and foremost, while behavioral biases may appear subjective, they are backed by extensive research in behavioral economics, with Prospect Theory awarded a Nobel Prize in Economics. In trading, leveraging known biases and behaviors can be instrumental in refining trading strategies.

Secondly, addressing behavioral biases in trading demands introspection. Understanding one’s thought processes and behaviors is pivotal, although it’s not as straightforward as integrating additional indicators into a trading strategy. However, acknowledging and addressing these biases is fundamental to trading success.

Drawing from Prospect Theory, traders tend to avoid risks when gains are at stake but are more inclined to take risks to prevent losses. Therefore, it’s crucial to not only consider profit-taking but also loss-taking behavior. By cutting losses early and allowing profits to grow, traders can achieve profitability. This principle is echoed by renowned traders worldwide, emphasizing the importance of managing loss trades effectively in trading strategies.

In loss trades, traders often exhibit a willingness to take risks to avoid losses, as suggested by Prospect Theory. However, this behavior can have detrimental effects on trading strategy. Instead of cutting losses early and moving on, traders may increase risk exposure in a bid to recover losses and achieve breakeven or profits. Adjusting stop-loss levels further away in losing trades reflects this tendency, undermining trading performance by allowing losses to escalate.

Hoc-trade AI diligently monitors this behavior, recognizing its significant negative impact on traders’ performance. Each trader gains insight into the personal effects of this behavior through their dashboard.

Similarly, on the profit front, a parallel detrimental behavior is observed. Rather than allowing profitable trades to flourish, traders often opt for smaller gains, influenced by Prospect Theory’s preference for secure profits over potential larger ones. Many traders manually close profitable positions prematurely, foregoing the opportunity to reach higher profit targets.

Similarly to the adjustment of Stop Losses in loss trades, Hoc-trade diligently monitors traders’ manual stops and simulates the individual impact of this behavior on their performance (simulating trade outcomes if traders had not manually stopped trades in profit).

Repeating these behaviors sets traders up for failure. Sustained profitability becomes challenging when profits remain small, and losses escalate. This tendency, elucidated by Prospect Theory, is human nature. To counteract this, traders must adapt behavior, as over 85% of traders are currently losing money. Countermeasures to toxic trading behavior include:

  1. Situational Awareness: Recognize and understand personal biases by increasing awareness. Adjustments begin with acknowledgment and understanding.
  2. Alternate Profit Metrics: Shift focus from monetary value to other metrics like risk or points/pips. By devaluing currency, traders reduce the emotional impact of gains and losses.
  3. Leverage Technology & Alerts: Utilize technology, like hoc-trade, to identify and address destructive behaviors. Receive real-time alerts to counteract detrimental actions, enhancing trading performance.

Advanced technology like Hoc-trade is designed to provide significant support in overcoming emotional and cognitive biases. However, traders must ultimately make decisions. Understanding, recognizing, and altering behavior are essential for maximizing the benefits of technology on trading performance.
