Today there was a SINGD entry in my Fidelity account at the post-RS value, trading up and down just fine. As of late night with markets closed, I now notice the SINGD entry has disappeared, and a CUSIP number only entry has appeared in the "dead area" of my account, reflecting the pre-RS shares count and price.....
Maybe it will stay this way for the 20 day period they mentioned, as untradable......
