Any thoughts on my portfolio - IAU, SPYG, SKYY, AIA, SOXX?

Looks like my portfolio, haha.

no: gold i do not have, though I should, SKYY & SOXX I like very much.

SPYG surely not a bad choice.

AIA interesting, I love CQQQ.

Finally: all very technology skewed, these can be very volatile...

Possibly would be wiser to have more non-technology sector ETFs included (like global indices, f.ex. IWDA) or more balanced ones like QQQ, and according to 'the textbooks' still different asset classes.

I feel, You think like me, but maybe my mistake is wanting to predict from past returns future results.

good luck. At least it worked in the past, a room where we are safe with assumptions.​​​
