Doesn't appear to be anything of substance to support their bounce...could just be an anomaly caused by unknown MM activity, like we see quite often in QMC, or a few folks swallowing the monthly "analyst buy rating" pump put out by Cannacord (taking turns w/ Liberum)...who apparently don't have to disclose their cozy insider broker relationship with Nanoco for some reason in the UK.
Nothing to sweat about either way...the proof will be in the balance sheets over the next year.
