I set an alarm at 4 a.m., and sleepily got up to check the holdings. RIVER's position was indeed a bit aggressive, and as I watched the unrealized losses start to widen, the decline within an hour was quite alarming. Without much thought, I made a quick decision to exit. Although it was a bit painful, I didn't hold on stubbornly and kept a core position to prevent a real rebound. When I woke up again, I decided to close the core position as well. Sometimes, holding on in this kind of market is just asking for trouble; being decisive is better. Instead of being stuck inside and feeling frustrated, it's better to keep some bullets to迎接 the next wave of opportunities. This has been a lesson every time—bigger positions are actually more dangerous. Hope I can seize the next market opportunity well!
