Dear @Xorbia
Keep your shares for the following reasons;
1. Your investment thesis is 4-5 years. 2021+4=2025. You've created this self-rule for a reason. Back yourself.
2. Nothing has broadly/epically changed with 3DP since 2021. Some would say thats bad. But the point is unless your thesis called for specific minutiae in each qrtly, then broadly the company is doing what it does. Don't listen to the FUD. Revisit your WRITTEN DOWN thesis and decide from there.
3. If you don't have your thesis written down. Create one. Writing forces the coalesce of your thoughts. It will be hard. It will be confusing at first. This is the point. As by the end, you will know what you want to do, and can link that decision to logic and not emotion.
