Lesson Learned: Over-leveraging on a 'sure bet' Kalshi contract
Was watching the $SPX close > 4500 by end of day contract a few weeks back. Seemed like a no-brainer with momentum building into the afternoon session. Price for 'Yes' was dirt cheap earlier in the day, but by the time I was free to trade, it had climbed considerably. Still looked good though, chart was showing a clear uptrend, futures were strong. Decided to go in heavy, heavier than I usually would on a daily expiration.
The market dipped sharply in the last 30 minutes. My 'sure bet' evaporated. Ended up taking a decent hit, much larger than my typical risk tolerance allows for a single contract. It was a classic case of FOMO combined with overconfidence, leading to sizing up aggressively on a short-duration, high-volatility event. Should have stuck to my usual sizing, even if the conviction felt strong. Live and learn.
It's a tough lesson, but thinking something is a "sure bet" is often when you're most vulnerable to over-leveraging. The market has a way of humbling even the most confident predictions.
