I’m 32
And up 125% (+$20k) on SMH.
I kept adding on the dips and now find myself holding 28.5% of my taxable account in SMH.
I see SMH as a long term hold, just maybe not ~1/3 of my account.
Do I take profit and pay the taxes at the end of the year or are we confident long term in the etf and let the % slowly fall over time?
Need some advice as to not make an impulsive / drastic decision.
Thanks!
