Investments in the stock market can be highly profitable, especially if the investor exercises due diligence and caution. Such investments, however, do not always flourish since most prospecting investors make critical mistakes that lead to significant losses. Of the many errors that stock market investors commit, five stand out.


In the financial sector, one should be sensitive to information that can appropriately advise investment decisions. Knee jerk reactions to certain situations may, however, make investors overreact. Even if such a response is in the right direction, an excessive reaction can lead to bias which generally drives wrong decisions and inputs. Overreacting can be countered by taking as much time as possible before completing decisions that can otherwise turn out to be detrimental to the investment portfolio.

Focusing on the short term

In the stock market, substantial profits can only be gained if the investor can endure. Sometimes, stocks may take up to 10 years to generate significant profits. Investors lacking patience by focusing on short term performance of stocks can lose out on portfolios where they would have otherwise reaped well.

Copying other investors blindly

In stock investments, investors can quickly be drawn into making decisions similar to other investors in the market. Following the herd blindly by doing what others are doing can derail an individual’s investment portfolios. This situation arises in cases where investment bubbles influence investors to prefer certain stocks and buy on impulse and peer pressure.


Anchoring arises in cases where investors rely on limited sources of information. This leads to making decisions based on the first set of information that one receives. As an investor, one should rely on multiple primary sources of information while avoiding opinionated sources as they may be erroneous.

Confirmation bias

Confirmation bias arises in cases where investors only look for information that confirms their point of view concerning making investment decisions. Such bias can deal a significant blow leading to massive losses as one becomes immune to the reality when it comes to the stock markets.

In conclusion, investing in the stock markets requires one to understand the various avenues of making critical mistakes and avoiding them as much as possible. Such knowledge is vital if the investor is to succeed in the otherwise volatile and sensitive stock market.
