I think with more exposure and experience over time, I'll be able to make 'better' decisions.
Trial and error is bound to stay, as the market is volatile and as much as we want to buy low and sell high, sometimes it just doesn't turn out the best!
Today my bank stocks $DBS Group Holdings(D05.SG)$ $UOB(U11.SG)$ $OCBC Bank(O39.SG)$ all tumbled so badly although they rose to all-time highs just a few weeks or even days ago!
Most importantly, staying calm and not being too emotionally attached nor affected by these challenges would be a good way to counter this. Let's hope the future brings surprises!
