Su Group Holdings Limited shares fall 3.03% premarket after Toronto stocks decline, led by energy sector.

Su Group Holdings Limited dropped 3.03% in premarket trading. The decline may be attributed to the overall market sentiment, as Toronto stocks advanced strongly in the first trading day after the long weekend, with only tech stocks and energy in decline at midday. Additionally, the widening of Canada's merchandise-trade deficit in June to a deficit of 5.86 billion Canadian dollars may have contributed to the negative sentiment in the market.
