In times like these, as an investor, one must take a step back and evaluate their intended decisions through the lens of "investing" versus "speculating". Never speculate with core capital. Recognising speculation from investment can be crucial to investing success in these situations. Finally, all performance-chasing - selling a fund that has trailed over the last three years to pick up one that has outperformed - is speculating rather than investing. It's time to be disciplined and stick to your plan.
