In reality 3 to 5 days does give a company the chance to time their release.
My old broker told me that good news is best released early in the week. Brokers work the news and it's only considered news the week it's released, so early in the week gives them the most time to work with their customers.
Bad news is best dumped after the close on Friday, and if really terrible, on a 3 day weekend if possible.
Given the opportunity, I believe NWBO will try to release early in a week, but not necessarily on Monday unless they have the word shortly before, and can plan for such a release. If notified on Monday, I suspect they'd stage it properly on Tuesday rather than rushing it out on Monday.
