C — risk first, prediction second.

Before earnings, I’d check four things: actual margin used, current margin requirements, position concentration, and excess liquidity. A stock can gap 10–20% overnight, while a higher margin requirement can amplify the pressure even if the underlying business story hasn’t changed.

The key is to preserve room to be wrong. Buying power is not the same as risk capacity. I’d also review FX debits and auto-conversion settings, especially when financing in one currency while holding assets in another.

Earnings are about expectations. Margin management is about survival. I’d rather miss part of a rally than be forced to sell into a gap down.

Financing Account Mini-Class
How exactly do I use a financing account? Does having a credit limit mean I've already borrowed money? How is financing interest calculated? When might a Margin Call be triggered? What should you pay attention to when using financing during earnings season? To address these most frequently encountered issues, we launched the "Margin Account Mini-Classroom" series, which breaks down the core mechanisms of margin accounts using simple examples, from financing limits, interest rates, and purchasing power to short selling, margin requirements, and risk management.

    Great reminder ahead of earnings 👏 The point that buying power isn’t the same as risk capacity is especially important. How do you usually decide what level of excess liquidity is enough when holding positions through earnings?

      I don’t use a fixed percentage. I usually stress-test a 15–20% earnings gap and make sure there’s still a comfortable buffer after factoring in margin requirements and FX risk. For me, excess liquidity is a safety cushion, not extra buying power.
