I received my documents today and they only reference a single security that I own - ARKG. I take it to mean that ARKG is the only security of interest, but it's hard to know for sure. Also, it seems to me that it might be best to use securities in a Roth IRA in order to avoid taxes on the income. I haven't decided whether or not to submit the paperwork but might try it more or less just to see how it works.
I am also thinking of participating in the program as a learning experience and to see how lucrative it might be.
The main point I wanted to know about is my risk and my downside. FAQ 5 on page 3 of the overview document states that the main risk is counterparty default. It states that the counterparty is Fidelity. So the question is - what is the likelihood that Fidelity will default on the program? My answer is - very low likelihood.
My wife is on board and we will probably try it. It can be terminated by me, or the "loan recalled" per the overview document.
