When borrowed conviction becomes borrowed risk.

You can follow an experienced investor and still misunderstand the risk you are taking.

You read that an investor you respect has bought a company.

You listen to their explanation. Read their analysis. Buy the shares.

Then the price falls.

You search for their latest interview. Check whether they still hold it. Feel relieved when they repeat their conviction.

Eventually, you sell at a loss.

“I should never follow anyone again.”

Before carrying that conclusion into your next decision, examine the experience.

Record what happened and what you believed

Investment Lessons Review gives you a place to preserve the experience before the outcome changes the story.

“Their research gave me enough confidence to buy. When the price fell, I could not assess the investment myself.”

Examine what you overlooked

“I did not know their position size, time horizon or reasons for selling. I had not considered how the investment fitted my own circumstances.”

Separate your reasoning, execution and behaviour from the outcome.

A falling price alone does not prove the decision was poor. Here, the review reveals how much the decision depended on someone else’s continuing reassurance.

Make the lesson usable

“Before committing money, I will write down my own reasons for investing, the evidence that supports them and what would make me reconsider.”

Save the lesson with relevant tags so you can retrieve it before a similar decision.

Return to review and revise

Did you apply the lesson?

Did it change your decision?

Does new evidence suggest the lesson needs refining?

Perhaps your next entry reads:

“I researched another investor’s idea, identified an assumption I could not evaluate and decided to wait.”

That gives you evidence of learning in practice.

You can export your Lessons Library and return to it before future decisions.
