Stay the Course 🌿
I was shaken. But I held firm. These are the records.
The market shakes every year. Interest rate hikes, wars, inflation, currency spikes, semiconductor crises — news headlines always sell fear. There were moments when, in the face of that fear, I didn't press the sell button, didn't stop my automatic transfers, and actually bought more.
This section is a raw record of those moments. It's not a well-crafted theory, but an honest account of why I held on even when watching my account melt down, and what I learned in the process.
The hardest thing in investing is not 'what to buy', but 'when not to sell'. I hope these writings become a small anchor for someone shaking in the midst of a market crash.
