By: musicwhiz As the saying goes: "Pride goes before a fall", and this means that one who is proud will eventually fall because of his over-inflated ego. This investment sin is a very intruiging one as it discusses one's ego and shows how it affects one's investment decisions and philsophy. Vanity is a direct result of pride and being vain in investing simply means that you start worshipping yourself as if you could do no wrong. Surprisingly (or maybe unsurprisingly), a survey conducted shows that men have a higher tendency to show excessive pride and an inflated ego when dealing with investments, and this could stem from the proverbial "male ego" which makes men aggressive and "kiasu". The "must0win" mentality may translate into fierce (and misplaced) pride in one's investing acumen and lead to one's eventual downfall. Women may also be prone to this but the survey mentioned that it is to a lesser extent. I am not going to go into a debate of the sexes but just wish to highlight that there are subtle differences in the way that men and women invest which are central to the topic I am discussing in this post. Perhaps I will discuss the differences between male and female investors in a future, more detailed post once I have collected sufficient "evidence" to form a theory.
