it's a crapshoot as to when and if the other large companies or other countries sovereign Nations enter into this marketplace within the United States. what this will do is on weakness as we saw a week and a half ago two weeks ago where we had profit taking and money rotating out of utilities going into other tech stocks this will provide the traders that see these cycles to enter on the weakness to give it that leg up when we see a 5% sell-off which is what we did see.. so you're going to have to decide for yourself at what point You're going to exit it's important that you understand that you can't hold this ETF forever because options are used for leverage and there's a cost to the options and there's a gradual decay that you can't see on a daily or weekly basis but over a 3 months 6 month 9 month window if the ETF plateaus that's when you will notice the largest companies underneath that comprise the CTF if you were to plot them on a chart and see when they move a couple percent higher the ztf is lagging that move and that's because there is a cost associated with this leverage.
