The Insider Buy/Sell Ratio for Directors in Canada's Homebuilding & Construction sector measures the ratio of stock purchases to sales by directors, reflecting their confidence in the sector's prospects. This metric is calculated by dividing the number of buy transactions by the number of sell transactions executed by directors within the homebuilding and construction sector over a 30-day period. A high ratio indicates strong confidence among directors, suggesting they see potential for growth or undervaluation in the sector.
