TSX Today: What to Watch for in Stocks on Wednesday, March 18

Even amid the ongoing Israel-Iran war, Canadian stocks continued to recover for a second consecutive session on Tuesday as investors awaited the Bank of Canada’s (BoC) and the U.S. Federal Reserve’s interest rate decisions and press conferences scheduled for Wednesday. The S&P/TSX Composite Index inched up by 52 points, or 0.2%, for the day to settle at 32,929, extending its week-to-date gains to 1.2%.

Even as sliding metals prices amid demand outlook concerns drove mining stocks lower, strong gains in other key sectors such as technology, healthcare, and financials pushed the TSX benchmark higher.

Top TSX Composite movers and active stocks

goeasy, ATS, NFI Group, and Bitfarms were the top-performing TSX stocks on Tuesday, with each climbing by at least 4.9%.

Shares of Lightspeed Commerce (TSX:LSPD) climbed 2.5% to $12.49 apiece, making it among the day’s top gainers on the Toronto Stock Exchange. This rally in LSPD stock came after the Montréal-based point-of-sale and payments platform company announced that its NuORDER division has entered a strategic partnership with Nordic digital retailer Boozt.

Under the deal, Boozt will use NuORDER’s platform to centralize assortments, orders, and product data, replacing manual workflows and improving buying intelligence. This collaboration aims to help Boozt make more informed assortment decisions and support profitable growth, while also strengthening NuORDER’s footprint in Europe. Investors appeared encouraged by the partnership as it highlights Lightspeed’s ongoing efforts to expand its B2B commerce network and deepen its presence in key international markets.

However, G Mining Ventures, OceanaGold, NovaGold Resources, and Canadian National Railway dived by at least 3.8% each, making them the session’s worst-performing TSX stocks.

Based on their daily trade volume, Canadian Natural Resources, TC Energy, Enbridge, Suncor Energy, and Whitecap Resources were the five most active stocks on the exchange.

TSX today

Commodity prices across the board fell in early Wednesday trading, which could pressure the resource-heavy main TSX index at the open today.

However, geopolitical developments will remain a key overhang for markets, as fresh reports of intensified Israeli strikes and the reported elimination of a senior Iranian intelligence official underscored the ongoing escalation in the conflict. These developments could keep investors cautious, especially as the war shows little sign of easing in the near term.

Moreover, interest rate decisions and central bank press releases from both sides of the border will remain on TSX investors’ radar today, which could set the tone for near-term market direction.

On the corporate events side, the TSX-listed Boyd Group Services and Power Corporation of Canada are set to announce their latest quarterly results today.
