The Nearmap Ltd(ASX: NEA) share price was the best performer on the index with a gain of 17.1%. Last week the aerial imagery technology and location data company released its annual report. Although there was no new information in Nearmap’s report, it reminded investors of its massive market opportunity. Nearmap may be generating significant revenues already in North America, but management estimates that it has only captured 1% to 2% of that market.
