In unserer kleinen Serie über die wichtigsten Fallen beim Investieren wollen wir uns in diesem Beitrag einmal dem Gambler's Fallacy Effect.
Here the gambler presumes that the next coin toss carries a memory of past results which will have a bearing on the future outcomes.
Hacking says that the gambler feels it is very unlikely for someone to get a double six in their first attempt.
Now, we know the probability of getting a double six is low irrespective of whether it is the first or the hundredth attempt.
The fallacy here is the incorrect belief that the player has been rolling dice for some time. The chances of having a boy or a girl child is pretty much the same.
Yet, these men judged that if they have a boys already born to them, the more probable next child will be a girl. The expectant fathers also feared that if more sons were born in the surrounding community, then they themselves would be more likely to have a daughter.
We see this fallacy in many expecting parents who after having multiple children of the same sex believe that they are due having a child of the opposite sex.
For example — in a deck of cards, if you draw the first card as the King of Spades and do not put back this card in the deck, the probability of the next card being a King is not the same as a Queen being drawn.
The probability of the next card being a King is 3 out of 51 5. This effect is particularly used in card counting systems like in blackjack.
Statistics are often used to make content more impressive and herein lies the problem. This same problem persists in investing where amateur investors look at the most recent reported data and conclude on investing decisions.
They have come to interpret that people believe short sequences of random events should be representative of longer ones.
This means if you were to see a bunch of reds at point x and after a few randomness, you see another red streak — one tends to believe that the population is largely red with some small streaks of black thrown into the mix.
Often we see investing made on the premise. One thinks anything can be bought because the macro-economic picture of the country is on a high.
And hence, your stock will also go up. This is far away from the truth with a number of stocks currently lingering at their week low even as the Indian Nifty and Sensex continues to touch new heights of 12, points and 40, points respectively.
At some point in time, you would have had a streak of six when rolling dice. Notice how in your next roll, you will turn your body as if to have figured out the exact movement of the body, hand, speed, distance and revolutions you require to get another six on the roll.
This mistaken belief is also called the internal locus of control. This would prevent people from gambling when they are losing. It would help them avoid the mistaken-thinking that their chances of winning increases in the next hand as they have been losing in the previous events.
We see this in investing aswell where investors purchase stocks and mutual funds which have been beaten down. This is not on analysis but on the hope that these would again rise up to their former glories.
It is not uncommon to see fervent trading activity on stocks which are fallen angels or penny stocks. In all likelihood, it is not possible to predict these truly random events.

What is the Gambler's Fallacy? Key Takeaways Gambler's fallacy refers to the erroneous thinking that a certain event is more or less likely, given a previous series of events.
It is also named Monte Carlo fallacy, after a casino in Las Vegas where it was observed in The Gambler's Fallacy line of thinking is incorrect because each event should be considered independent and its results have no bearing on past or present occurrences.
Investors often commit Gambler's fallacy when they believe that a stock will lose or gain value after a series of trading sessions with the exact opposite movement.

Functional magnetic resonance imaging has shown that after losing a bet or gamble, known as riskloss, the frontoparietal network of the brain is activated, resulting in more risk-taking behavior.
In contrast, there is decreased activity in the amygdala , caudate , and ventral striatum after a riskloss.
Activation in the amygdala is negatively correlated with gambler's fallacy, so that the more activity exhibited in the amygdala, the less likely an individual is to fall prey to the gambler's fallacy.
These results suggest that gambler's fallacy relies more on the prefrontal cortex, which is responsible for executive, goal-directed processes, and less on the brain areas that control affective decision-making.
The desire to continue gambling or betting is controlled by the striatum , which supports a choice-outcome contingency learning method. The striatum processes the errors in prediction and the behavior changes accordingly.
After a win, the positive behavior is reinforced and after a loss, the behavior is conditioned to be avoided. In individuals exhibiting the gambler's fallacy, this choice-outcome contingency method is impaired, and they continue to make risks after a series of losses.
The gambler's fallacy is a deep-seated cognitive bias and can be very hard to overcome. Educating individuals about the nature of randomness has not always proven effective in reducing or eliminating any manifestation of the fallacy.
Participants in a study by Beach and Swensson in were shown a shuffled deck of index cards with shapes on them, and were instructed to guess which shape would come next in a sequence.
The experimental group of participants was informed about the nature and existence of the gambler's fallacy, and were explicitly instructed not to rely on run dependency to make their guesses.
The control group was not given this information. The response styles of the two groups were similar, indicating that the experimental group still based their choices on the length of the run sequence.
This led to the conclusion that instructing individuals about randomness is not sufficient in lessening the gambler's fallacy. An individual's susceptibility to the gambler's fallacy may decrease with age.
A study by Fischbein and Schnarch in administered a questionnaire to five groups: students in grades 5, 7, 9, 11, and college students specializing in teaching mathematics.
None of the participants had received any prior education regarding probability. The question asked was: "Ronni flipped a coin three times and in all cases heads came up.
Ronni intends to flip the coin again. What is the chance of getting heads the fourth time? Fischbein and Schnarch theorized that an individual's tendency to rely on the representativeness heuristic and other cognitive biases can be overcome with age.
Another possible solution comes from Roney and Trick, Gestalt psychologists who suggest that the fallacy may be eliminated as a result of grouping.
When a future event such as a coin toss is described as part of a sequence, no matter how arbitrarily, a person will automatically consider the event as it relates to the past events, resulting in the gambler's fallacy.
When a person considers every event as independent, the fallacy can be greatly reduced. Roney and Trick told participants in their experiment that they were betting on either two blocks of six coin tosses, or on two blocks of seven coin tosses.
The fourth, fifth, and sixth tosses all had the same outcome, either three heads or three tails. The seventh toss was grouped with either the end of one block, or the beginning of the next block.
Participants exhibited the strongest gambler's fallacy when the seventh trial was part of the first block, directly after the sequence of three heads or tails.
The researchers pointed out that the participants that did not show the gambler's fallacy showed less confidence in their bets and bet fewer times than the participants who picked with the gambler's fallacy.
When the seventh trial was grouped with the second block, and was perceived as not being part of a streak, the gambler's fallacy did not occur.
Roney and Trick argued that instead of teaching individuals about the nature of randomness, the fallacy could be avoided by training people to treat each event as if it is a beginning and not a continuation of previous events.
They suggested that this would prevent people from gambling when they are losing, in the mistaken hope that their chances of winning are due to increase based on an interaction with previous events.
Studies have found that asylum judges, loan officers, baseball umpires and lotto players employ the gambler's fallacy consistently in their decision-making.

Hot Hand Definition The hot hand is the notion that because one has had a string of successes, an individual or entity is more likely to have continued success.
Partner Links. Related Articles. Investopedia is part of the Dotdash publishing family. The roulette wheel's ball had fallen on black several times in a row.
This led people to believe that it would fall on red soon and they started pushing their chips, betting that the ball would fall in a red square on the next roulette wheel turn.
The ball fell on the red square after 27 turns. Accounts state that millions of dollars had been lost by then.
This line of thinking in a Gambler's Fallacy or Monte Carlo Fallacy represents an inaccurate understanding of probability. This concept can apply to investing.
They do so because they erroneously believe that because of the string of successive gains, the position is now much more likely to decline.
For example, consider a series of 10 coin flips that have all landed with the "heads" side up. Under the Gambler's Fallacy, a person might predict that the next coin flip is more likely to land with the "tails" side up.
Each coin flip is an independent event, which means that any and all previous flips have no bearing on future flips. If before any coins were flipped a gambler were offered a chance to bet that 11 coin flips would result in 11 heads, the wise choice would be to turn it down because the probability of 11 coin flips resulting in 11 heads is extremely low.
The fallacy comes in believing that with 10 heads having already occurred, the 11th is now less likely. Risk Management. Until then each spin saw a greater number of people pushing their chips over to red.
While the people who put money on the 27th spin won a lot of money, a lot more people lost their money due to the long streak of blacks.
The fallacy is more omnipresent as everyone have held the belief that a streak has to come to an end. We see this most prominently in sports. People predict that the 4th shot in a penalty shootout will be saved because the last 3 went in.
Now we all know that the first, second or third penalty has no bearing on the fourth penalty. And yet the fallacy kicks in.
This is inspite of no scientific evidence to suggest so. Even if there is no continuity in the process. Now, the outcomes of a single toss are independent.
And the probability of getting a heads on the next toss is as much as getting a tails i. He tends to believe that the chance of a third heads on another toss is a still lower probability.
This However, one has to account for the first and second toss to have already happened. When the gamblers were done with Spin 25, they must have wondered statistically.
Statistically, this thinking was flawed because the question was not if the next-spin-in-a-series-ofspins will fall on a red. The correct thinking should have been that the next spin too has a chance of a black or red square.
A study was conducted by Fischbein and Schnarch in They administered a questionnaire to five student groups from grades 5, 7, 9, 11, and college students.
None of the participants had received any prior education regarding probability. Ronni intends to flip the coin again.
What is the chance of getting heads the fourth time? In our coin toss example, the gambler might see a streak of heads.
This becomes a precursor to what he thinks is likely to come next — another head. This too is a fallacy. Here the gambler presumes that the next coin toss carries a memory of past results which will have a bearing on the future outcomes.
Hacking says that the gambler feels it is very unlikely for someone to get a double six in their first attempt. Now, we know the probability of getting a double six is low irrespective of whether it is the first or the hundredth attempt.
