Investor Emotions and Cognitive Biases in a Bearish Market Simulation: A Qualitative Study
Abstract
1. Introduction
2. State of the Art
- Loss aversion and the disposition effect: investors resist realizing losses, extending losing positions (Kahneman & Tversky, 1979; Fan & Neupane, 2024).
- Anchoring: reliance on initial performance or familiar indicators (Sharma & Firoz, 2020).
- Confirmation bias: selective attention to information supporting prior beliefs (Konteos et al., 2018).
- Overconfidence: overestimating skills and underestimating risks, especially after early success (Y. Wang, 2023).
- Familiarity and herd behavior: preference for well-known assets or imitation of peers (Utari et al., 2024).

Appendix A.4. Complete Thematic Analysis of Semi-Structured Interviews (SSI) and Focus Group (FG)
Student | Emotions | Biases | Decision-Making Process |
I.1. | Emotions were strongly linked to stock market performance, fluctuating between happiness (code 1) and disappointment (code 2). He said: “Our mood depended on the stock market and the shares we had bought. If they went up, we were happy; if they went down, we were a little disappointed.” (SSI) “When we made a profit, we felt happiness, satisfaction and pride.” (FG) “Whether we made a profit or a loss, I still felt anxious.” (FG) “The next day, I felt anxious and afraid. Because I thought, that’s it, it’s over, there’s nothing I can do now.” (FG) | A strong loss aversion (code 1) was present, perceiving virtual losses as real: “This feeling eats away at us. We ask ourselves: ‘Could I have done better? Did I make the right choice? What if…?’” (SSI) “We say to ourselves it’s just a simulation. But inside, it’s not just a simulation, because we want to perform, we want to be the best. And it’s that feeling, that desire, that drives us.” (SSI) | Faced with losses, the student chose to cut his losses (code 1) by closing his positions and adopting a resigned attitude: “I bought shares at the very beginning and then I saw that they weren’t moving much because the market was down. Then I saw that we were losing money, so I cut my losses.” (SSI) “We decided to cut our losses and go into passive mode. And we’ll see if we can do anything else.” (SSI) |
I.2. | The student experienced fear turning into anxiety (code 1a) in response to the continuing market decline and uncertainty: “When the markets started to fall and it didn’t stop, I felt real anxiety. I thought it was never-ending, that I didn’t know where it would stop. It was completely unknown and it paralyzed me.” (SSI) Fear turned into frustration and a feeling of helplessness (code 1b) also emerged: “It was extremely frustrating to see my strategies not working while the market kept falling. I felt like I was fighting a wall, unable to do anything.” (SSI) | A pronounced loss aversion (code 1) prevented him from reducing his positions in the hope of a rebound: “When I saw the losses mounting on my positions, I found it very difficult to reduce them. I kept waiting for a rebound, even when all the signs were pointing to a fall.’ It was unbearable to accept the loss, even though I knew it was only virtual.” (SSI) Confirmation bias (code 2) is evident in the search for positive information to validate hopes of a recovery: “I started looking for articles and analysts who said the market was going to rebound, even though the majority said the opposite. I wanted it to go back up so badly that I clung to every little bit of positive news.” (SSI) “If I see something that confirms my idea, I think that news will have a certain impact, and if I see other news that confirms it, it will have a confirmation bias.” (FG) | His reaction was decision paralysis (code 1): “There were times when I just couldn’t look at my portfolio for hours. I didn’t know what to do, I was overwhelmed, so I did nothing. I hoped it would sort itself out.” (SSI) and impulsive decision-making (code 2) or “revenge” strategies after big losses: “After a big loss, I would sometimes make very quick moves, without really thinking, just to try to recoup a little. It was impulsive, I knew it wasn’t the right approach, but I was so angry.” (SSI) |
I.3. | Being at the top of the rankings generated feelings of happiness (code 1) and satisfaction: “I was in first place. It was quite a thrill. What’s more, I knew I was going to win, but I also knew I was taking a big risk because I was already in first place on the second day, and I said to myself, either I cut everything out and stay in first place, or I go for it. But I took the risk because of my ego.” (SSI) He also expressed fear (code 2): “I even dreamed that my accounts were empty. It was stressful not knowing where things were going.” (SSI) | A strong loss aversion (code 1) and a belief that prices always come back led him to hold on to losing positions: “I didn’t want to cut my losses. I don’t really like that. Because for me, the price always comes back.” (SSI) “But anyway, in three days, there was little chance that the price would return to its previous level, but I still hoped it would. That’s what you shouldn’t do, hope.” (SSI) Overconfidence (code 2) linked to his ego and initial performance encouraged him to maintain a high-risk stance: “I remain convinced that I have to take this risk and that if I’ve done it, I’ll continue to do so until the end.” (SSI) “It’s important not to be self-deprecating, to be confident, and to take mitigated risks.” (FG) | The student was caught in a vicious cycle of impulsive decision-making (code 1) and “revenge,” taking more risks after losses: “Then you try to take more risks. And you try to get revenge. And then it’s even worse. It’s a vicious cycle, it’s a never-ending cycle.” (SSI) He admitted that he mismanaged the size of his positions, leading to accelerated losses: “Or sometimes I get the position size wrong. Then the market moves 10 times faster. And it’s very difficult, because it’s really strange. I mean, the blood rushes to your head. You think, ‘Oh, what am I doing?’” (SSI) Confirmation bias led him to reinforce his winning positions: “And often, when I get my confirmations, I get back into the position to increase the risk a little bit, and the risk paid off because I went up to 4%, I think.” (SSI) |
I.4. | The student began with optimism (code 1): “I have a week off, so there’s no reason I can’t do this. Instead of staying at home or doing something else, why not do this during the week?” (SSI) The inactivity of the market quickly turned into fear (code 2), frustration, helplessness, and a lack of motivation: “But nothing was happening. So we lost motivation.” and “We were there. Disappointed.” (SSI) | An anchoring bias (code 1) was observed, with disappointment arising when the situation did not improve despite initial investment: “I tell myself that there’s nothing more to be done, because it’s the last day, and you’ve seen the stock market, there’s going to be no miracle.” (SSI) “I would prefer to anchor myself to something I know, such as indicators, because I believe they slightly improve performance. In the end, it was the only thing I could base my decision on.” (FG) | Emotions and bias led to decision paralysis (code 1) and resignation, with the student feeling that there was nothing left to do in the absence of a market miracle: “We realized that, well, there was nothing else we could do.” (SSI) |
I.5. | The student experienced fear (code 1) of losing his money, even if it was virtual, which he found “frustrating”: “The moment that struck me the most was at the very end, at the end of the third day, when we got the rankings and saw what we had lost, even if it wasn’t real money. It’s still pretty frustrating to see that you’ve lost so much money.” “I still felt a little stressed when I was making transactions, when I was buying or selling, because I was afraid of losing my money, even if it wasn’t real money.” (SSI). He also had trouble adapting to the bear market: “It’s true that the market was down. So I had a little trouble adapting.” (SSI) “I was already desperate that it could change positively all of a sudden.” (FG) “My emotions about the situation took over and encouraged me to stop doing anything. If there’s something you can do, do it. But it won’t be something that will change the situation much.” (FG) | A confirmation bias (code 1) drove him to look for signs of recovery on the charts: “I was trying to look at the charts all the time to see if there was a chance it would go back up, if there was a small dip and then it would go back up.” (SSI) “Basically, I was following companies that I knew a little bit about, but since others were telling me that these were companies that were making big profits, I thought, why not? If it can bring me the same thing as him, but I didn’t dare to put in the same amounts.” (FG) He also looked for social comfort (herd effect, code 2): “When I saw that I had lost quite a lot too, I told myself that it wasn’t just me and that others were also experiencing significant losses.” (SSI) He also tried to copy others (herd effect, code 2) “I took other people’s ideas and thought I could use them to get into the same situation as them, but I didn’t do it at the right time, and it had a negative impact on me.” (FG) | Impulsive decision-making (code 1) (about sales) His decisions were focused on selling to limit losses: “I was more interested in selling than buying.” (SSI) “I kept selling anyway, and I’m going to try to limit my losses.” and “I told myself that as I made gains, I would sell again.” (FG) “On the one hand, because I’ve taken a step back, I think it’s a bit like what you said yesterday, that it’s a bit screwed up and all, but hey, let’s go for it, we might as well take the risk.” (FG) |
I.6. | A strong emotion of disappointment (code 1) was reported when moving from first to last place: “It was disappointing because… Actually, on the first day, I was in first place. So I was very happy and very motivated.” (SSI) and “And then I saw that I had dropped down anyway. It was disappointing. From first to last. Yes. That was the disappointment.” (SSI) He maintained optimism (code 2) despite the losses: “Up until then, you said to yourself, ‘Come on, I believe in it, I hope things will change.’ When there was a small gap, like 1% or 1.5%, I said to myself that with a lot of luck, it could work out, but at that point, I knew it wasn’t possible.” (SSI) “And so I said to myself that it’s true that you have to take risks, and so the desire to be first, let’s say, had an impact on decision-making.” (FG) | The anchoring bias (code 1) on initial performance (being first) made the downfall even harder to deal with: “At that point, I thought, ‘I shouldn’t have invested so much in companies that were… well, that were underperforming.’ So that was like a letdown. I was disappointed.” (SSI) | Disappointment was followed by decision paralysis (code 1) and resignation, with the student eventually “deleting” everything from his portfolio: “So it was just small gains and small losses. And that’s why, in the end, I realized it wasn’t working, so I deleted everything. I preferred to just leave it empty.” (SSI) “At the last minute, you say to yourself, ‘There’s no point anymore.’ Yes, at that point, I was actually 3% away from finishing, it wasn’t possible.” (SSI) |
I.7. | The student expressed fear (code 1) of losing and intense stress: “A lot of stress. I felt a little stressed because if the share price went up, it was okay. If it went down, I felt a little stressed.” and “I was afraid of losing. Even though it was only virtual money, I was still afraid of losing it.” (SSI) “When you’re losing, you don’t want to sell, you don’t want to validate a loss.” (FG) “I tend to hold on to my position rather than take risks and sell and try something else.” (FG) | Even if biases were not noticeable, the absence of emotional regulation was noted: “No, I didn’t do anything to manage my stress. I don’t know how you can manage it in real life. But no, I didn’t do anything.” (SSI) “Emotions are not necessarily known. It wasn’t instantaneous. I didn’t even know to what degree. It was more or less precise.” (FG) | Fear prompted him to make impulsive decisions (code 1) (sales) to cut his losses, rather than wait for a rebound: “I was afraid of losing more. So I said to myself, ‘I’m just going to stop.’ So I think when it [the stock] started to fall, I sold it right away. Instead of waiting for it to go up again”. (SSI) |
I.8. | The student quickly experienced fear (code 1a), which turned into frustration and a feeling of not being “good enough” compared to the other participants: “Right away, I quickly felt, how can I put it, that I wasn’t up to the task. I felt left behind compared to the others, because they had already participated in scholarship competitions or were trading on their own, so they were talking about things, but I thought to myself, we didn’t take the same classes, it’s not possible.” (SSI) “When I was winning, I knew very well that it was just pure luck.” (FG) His fear (code 1b) turned into abandonment and resignation: “Complete abandonment” and “In the end, I told myself it was a lost cause.” (SSI) | A strong loss aversion (code 1) caused him to hesitate about what decision to make: “I didn’t really know when to sell, whether to sell now or wait for the market to recover.” (FG). The participant then quickly cut his positions: “So I cut everything because I thought, no, this isn’t possible.” (SSI) “I decided to cut my losses at the end because I thought, after doing some research, that it was better to cut your losses than let them fall indefinitely.” (SSI). He noted that the feeling of loss is twice as strong as that of gain: “But I read that when you lose something, you suffer a loss, and the feeling you get is twice as strong as a gain. I think that’s what I took away from that book.” (SSI). This passage shows a search for information to understand the phenomenon of loss. | His frustration led to decision-making paralysis (code 1) facing a market he considered hopeless: “The market is still bearish, there’s no point in trying anything.” and “On the afternoon of the third day, yes. Because there comes a point when you say to yourself, the market is down, there’s no point in trying anything.” (SSI) |

Main Theme | Sub-Code/Manifestation | Representative Quote (SSI or FG) | Analytical Synthesis |
---|---|---|---|
Emotions | Fear/Anxiety | “When the markets started to fall, I felt real anxiety… I didn’t know where it would stop.” (SSI) | Uncertainty resulted in paralyzing fear, often resulting in withdrawal or inaction. |
Frustration/Helplessness | “It was extremely frustrating to see my strategies fail… I felt like fighting against a wall.” (SSI) | Frustration produced a loss of control, leading either to impulsive decisions or resignation. | |
Joy/Pride (early success) | “I was in first place, it was thrilling… I kept taking risks.” (SSI) | Early success encouraged overconfidence, reinforced by ego and competition. | |
Cognitive Biases | Loss Aversion | “I couldn’t cut my positions, I kept hoping for a rebound.” (SSI) | Emotional pain associated with losses blocked strategic adjustment, leading to inertia. |
Confirmation Bias | “I searched for articles saying the market would rebound, even when most said the opposite.” (SSI) | Negative emotions oriented attention toward selective, reassuring signals. | |
Anchoring | “I clung to my first positive results… I struggled to change strategy.” (SSI) | Emotional attachment to initial performance prevented rational re-evaluation. | |
Overconfidence | “I thought I was in control, that it would pay off…” (FG) | Satisfaction and pride fostered an illusion of control and persistence in risky choices. | |
Herding/Social Comfort | “Seeing others lose as well reassured me.” (SSI) | Social comparison mitigated the pain of losses but justified collective persistence. | |
Decision-Making | Paralysis/Withdrawal | “I didn’t know what to do, so I did nothing.” (SSI) | Anxiety and discouragement led to a “wait-and-see” posture, sometimes leaving portfolios empty. |
Impulsive/Revenge Decisions | “After a big loss, I made quick moves just to recover.” (SSI) | Frustration and anger resulted in revenge trading and excessive risk-taking. | |
Persistence of Inadequate Strategies | “I remain convinced I must take this risk, even if it hurts me.” (SSI) | Ego and overconfidence locked participants into unsuitable strategies. |
