Four pages a beginner investor should keep before they pick a stock

Most beginners do not fail because they picked the “wrong” ticker. They fail because they have no record of why they bought, what they already own, or what they still do not understand.


Keep four pages. Paper or Notion — the tool matters less than using them every time.


1. A holdings list

Ticker, number of shares, cost, and the account it sits in. If you cannot list this in five minutes, you are not ready to add more.


2. A one-page research note

For anything new: what the company or fund does, how it makes money, the main risk you can name, and one number you will watch. If you cannot fill that, you are guessing.


3. A decision journal

Date, what you did (buy, sell, or skip), why, and what would change your mind. Skipping is a decision. Write it down.


4. A simple allocation snapshot

Cash vs stocks vs funds. Not a 12-tab model. Just enough to see if one idea is already most of your money.


Do this for 30 days before you add another strategy, another app, or another “hot” name. The edge at the start is not more information. It is a system you will actually open.


None of this is personalized advice. It is a way to stop trading from memory.
