Stock price when the opinion was issued
ZQQ is the NASDAQ 100. COST is in the top 10 holdings. Choose this one for more growth long term, but it's absolutely expensive right now. TPU is broader US large-cap exposure. Doesn't track the S&P 500, but very similar. JPM is one of the top 10 holdings.
If you're putting new $$ to work, avoid both for now.
It is a solid ETF at quite a low cost. Its companies, tech and otherwise are so cemented and still seeing growth. Tech is concentrated on higher tech names. He is holding and adding some.
