Limiti psicologici nel trading:
Anchoring Effect - We credit and easily become attached to any number we hear. Unfounded financial hype and unrealistic "price targets" have the same effect. Often, it seems, an analyst cites a "price target" for a stock in order to influence investors by putting a number into their heads. Fifty-two-week high (or low) at which the stock had been selling have the same effet, traders continue to base their deliberations on this anchor.
Availability error - is the inclination to view any story, whether political, personal, or financial, through the lens of a superficially similar story that is psycho-logically available.
Confirmation bias - refers to the way we check a hypothesis by observing instances that confirm it and ignoring those that don't.
Status quo bias - If subjects are told, for example, that they've inherited a good deal of money and then asked which of four investment options (an aggressive stock portfolio, a more balanced collection of equities, a municipal bond fund, or U.S. Treasuries) they would prefer to invest it in, the percentages choosing each are fairly evenly distributed.
Endowment effect - another kindred bias, is an inclination to endow one's holdings with more value than they have simply because one holds them. "It's my stock and I love it.". That passively endured losses induce less regret than losses that follow active involvement.
Most people tend to assume less risk to obtain gains than they do to avoid losses. People perceive more pain after incurring a financial loss than they do pleasure after achieving an equivalent gain. In the extreme case, desperate fears about losing a lot of money induce people to take enormous risks with their money.
