Fear and greed will always drive markets. Take the higher path. Research and due diligence isn't only about understanding what you are investing in, but to also be accountable to yourself, to your money, and to your purpose in trading and investing. If you are trading, stick to your system and to your strategy. If you are investing, stay true to the fundamentals. In both cases, an increased knowledge will better equip you to have more conviction in your thesis. Red days are always a good reminder. It's also not the time to panic sell. Enter and exit with conviction and according to the plan. Not based on your emotion.
