The explanation is in the following (very recent) LINKS. Bottom line, SGOC was warned last May about getting booted from NASDAQ if it didn't catch-up with its grossly delinquent FILINGS. I, myself, had tossed it into my WATCH LIST the day BEFORE it skyrocketed, after it had appeared for a short period on Barchart's "HOT PENNY STOCKS" list; at least I THINK that was how it got into MY watch list. Bottom line, I TOO missed this one, but I DID see clearly that it was already UP by circa 200% early morning on 7-9-21 (Frid.). One thing I do know for sure, is that NONE of iHub's renowned penny pickers had detected it. If they HAD, they surely would have BOASTED about such right on THIS Board, & on "Momo's Breakout Boards", etc. Heck, this beast had hit circa 590% UP that day, with plenty of VOLUME for anyone to make a quick score.
