You nailed it all and this was the most egregious:
Misstep 2:
NWBO allowed a 3rd party whose primary purpose was not amplifying the news for the benefit of shareholders to release TLD and those they entrusted managed to foreground the bad news about PFS instead of the good news about OS.
NWBO meanwhile practically sat on their hands on media and investor relations.
The 'world' was tuned in to see the results and the very first slide addressing results said "failed to meet primary endpoint". That's when the MM group moved, that's when AF sounded off on twitter, that's literally exactly when the share price crashed.
Nobody is going to wait until the end of a presentation to act on a binary event when the first slide they see says "failed to meet primary endpoint". Doesn't matter what is said after that, people are immediately scrambling to exit their positions.
Absolute trainwreck of a data release, and Linda Powerless should have been relieved of her duties on the spot.
Not missteps, blantant errors and obvious mistakes by mute inept nonmanagement. L worthless does not have a clue about how to run this company, except into the ground. But she is getting rich and does not give a shite about SH.
