Considering the significant recent purchases from multiple directors at prices ranging from 31 to 41 cents, does this mean the recent price weakness is a golden buying opportunity that won't last long?

I purchased some shares on the presumption of significant recovery, based on the directors purchases. I would have been kicking myself if the shares bounced back suddenly and significantly and I had not purchased.
