TSX Outpaces S&P 500 in 2026 Amid Currency Fluctuations and Sector Divergence

Canada’s benchmark S&P/TSX Composite Index has outpaced the S&P 500 so far in 2026, with both North American indices trading near all-time highs. However, for Canadian investors, the decision between domestic and U.S. equities is complicated by currency risk and divergent sector leadership.

Performance by the Numbers

As of August 12, 2026, the S&P/TSX Composite has shown stronger performance on a year-to-date and one-year basis, though the S&P 500 has recently gained momentum. According to data from Investing.com, the TSX has a notable lead of nearly 11 percentage points over the past year.

• Year-to-Date Return: TSX +15.13% vs. S&P 500 +12.69%
• 1-Year Return: TSX +31.19% vs. S&P 500 +20.25%
• 6-Month Return: S&P 500 +13.44% vs. TSX +12.83%

The data shows the S&P 500's performance accelerating over the past six months, nearly closing the gap with its Canadian counterpart over that shorter timeframe.

The Currency Conundrum

A key factor for Canadian investors is the weakening loonie. The USD/CAD exchange rate stood at 1.3944 on August 12, representing a 1.60% increase for the U.S. dollar year-to-date. This currency movement acts as a tailwind for Canadians holding U.S. assets, amplifying returns when converted back into Canadian dollars.

Conversely, a weaker loonie makes new investments in the S&P 500 more expensive to fund from Canada. The TSX, priced in the domestic currency, carries no foreign exchange risk for Canadian investors. Future divergence in monetary policy between the Bank of Canada and the U.S. Federal Reserve remains a primary risk for the exchange rate.

Sector Outlook and Technical Signals

The two indices have vastly different compositions that influence their performance in the current macroeconomic environment. The TSX is heavily weighted toward financials, energy, and materials, which benefit from factors like elevated oil prices, with Brent crude trading near $90 per barrel. The S&P 500, in contrast, is dominated by technology and AI-related companies capitalizing on a wave of infrastructure spending.

Technical indicators suggest both markets are in a mature uptrend. The TSX's monthly Relative Strength Index (RSI) is at 82.6, a level considered deeply overbought that has historically preceded market pullbacks. The S&P 500's monthly RSI is also in overbought territory at 75.6, though to a lesser extent. These signals suggest that while the trend remains positive, the potential for a near-term correction has increased.
