I bought $DBS(D05.SG) at S$57.51 on 7 April 2026. At the time, I was comfortable holding the stock, but I noticed that the share price was fluctuating after my purchase. As the price moved around, I became concerned that the gains might reverse, so I decided to take profit rather than continue holding.

I sold my DBS shares at S$59.00 on 7 May 2026, making a small profit of around S$1.49 per share

Initially, I felt that selling at a profit was a reasonable decision. However, I later regretted the decision because DBS continued to rise after I sold. The share price moved above S$77 as of now, meaning I exited before a further upward move.

The biggest lesson for me was that short-term price fluctuations do not necessarily mean that I should exit a stock when my original investment thesis has not changed.

Looking back, I focused too much on the price movements between my entry and exit points and became too eager to lock in a small profit. Instead of reacting to every fluctuation, I could have considered whether the underlying fundamentals and my original reasons for buying DBS were still intact.
