An Investment journal

I love the idea of an investment journal.

When you jot down your thesis for buying a particular stock—the research, the analysis, the reasons behind your decision—you’re making a commitment to your future self. You’re saying, “This is why I’m doing this, and I want to remember why, even if the stock takes an unexpected turn.”

The real value of journaling becomes evident when the stock moves, especially in your favor. Instead of attributing it solely to your genius, you can review your journal to see if the actual outcome aligns with what you predicted. It keeps you honest and serves as a reality check against hindsight bias, the tricky tendency to see events as predictable or obvious after they’ve occurred. As Nassim Taleb and others touch on you don’t want to mistake luck for skill, and a journal helps here.

I recently created an investment journal, now available on Amazon.

It’s pretty simple and includes basic elements like space to record pre-trade and post-trade thoughts, along with some checklists. (More on it here) While it’s easy and convenient to do this digitally, for those who prefer to record things physically, it may be worth checking out.
