$iShares 20+ Year Treasury Bond ETF (TLT.US)$
All my old friends know that I've been waiting too long for tlt to break through 95, and the flowers have withered. Finally, today it broke through. However, looking at the weekly chart, there is finally hope for a breakthrough this week! But tomorrow's big non-farm payroll is crucial, so the weekly chart can only be confirmed tomorrow. I don't plan to rush today.
If the breakthrough is confirmed tomorrow, I will consider establishing a position in tlt (currently not holding positions).
The biggest risk for tlt is the return of inflation, similar to the 1970s. At that time, there was a problem with oil supply, which won't happen today. But what we need to worry about today is the supply of industrial products. As we all know, the industrial chain is shifting from the first industrial country to the world, but this process is long. If there is a link missing, it may trigger an industrial product crisis and lead to inflation. That's the only thing I'm worried about.
If it really happens, the world will be over, either the third world war or the second cold war, in short, there is no good thing.
I hope this doesn't happen.
