Investor Psychology: Action Bias vs. Decision Paralysis in Markets

Investor Psychology: Action Bias vs. Decision Paralysis in Markets

Imagine you have a piggy bank and want to make your money grow by buying special toys (stocks).

Sometimes, when the toy store gets super busy and prices go crazy, you might feel like you *have* to buy or sell something right away, even if it's not the best time.

This is like 'action bias' – wanting to do something.

On the other hand, sometimes there are so many cool toys to choose from, and you read so many reviews, that you can't decide which one to pick, so you end up not buying any.

This is 'decision paralysis.'

The problem is when you swing between these two feelings.

You might sell your toys when everyone else is panicking (selling low), and then when the toys get really popular again, you jump in and buy them at their highest price (buying high).

The best way to stop this is to have a plan for which toys you want and when you'll buy or sell them, stick to that plan, and not worry too much every single day.

It's more important to have a good plan than to always be doing something or getting stuck trying to pick the perfect toy.
