Stock price when the opinion was issued
This is riding a monster trend and now you need to focus on managing your potential downside. Technology is non-mean reverting sector which is great, but the price is at very high valuations now. You may consider setting stops, but would continue to hold. Remember this sector dropped 90% on a sell off back in 2000.
Doesn't own it, but uses it as a benchmark to gauge his performance. You're probably going to get a pullback.
Given that it's such a large ETF, you might want to write some calls on it just a bit higher, and manage it as you go through. Roll up once it gets to the price target. Don't write the call too far out but, say, 1 month out.
Technology is interesting in the sense that we don’t have the same bubble we had in the late 1990s, because the values are not crazy. Tech stocks are trading on pretty reasonable P/E ratios. Probably a good portfolio filler, but if you want higher returns, he would look elsewhere.
