Most successful investment is Meta: Holding it a for long time (bought initial position around 20), add aggressively during major pullbacks --- big 21-22 all-in VR pullback around 99, 2024 pullback around 480-520. Now the second largest holding in portfolio.
Tesla is my largest holding for now but I think there is some luck factor in it. Will need to wait for another 5 years to see if Tesla could become the most successful investment. Too early to call on this one.
Most unsuccesful investment is not the trading loss, but the inability to commit to AMZN. Have been looking at AMZN for a long long time, but for whatever reason, I was not able to pull the trigger. I think emotionally, i could not recover from the fact that i once owned AMZN back in 1999 and sold it wayyyyy too earlier. I think if I commit to AMZN, the return will be much much higher than MSFT which I decide to stay in for last 10 years.
