#Gate广场新手村第十期 Last March, when a stock I held plummeted 15% in a single day, I almost instinctively wanted to cut my losses during trading hours. But when I opened my notes and saw the reason for buying—"industry demand is still expanding, valuation is safe"—I forced myself to close the trading app and went for a walk. An hour later, after calming down, I realized my panic came from giving back previous gains, not from any change in logic. In the end, I stuck to my original plan and added to my position at the support level. Two months later, the stock price recovered and hit a new high. That experience taught me deeply: what counters emotion is not a more complex strategy, but executing the simple discipline you've written down.
