Key Takeaways

  • The S&P/TSX Composite Index closed at 35,620.03, down 629 points or about 1.74% on October 30, 2026.
  • Despite Friday's selloff, the TSX ended October up 1.09% and remained up 12.32% in 2026.
  • A 1.74% decline would equal about $870 on a $50,000 portfolio tracking the index exactly.

TSX Plunges 629 Points — But October Still Ends in the Green

Imagine checking your TFSA or RRSP on Friday evening and seeing hundreds of dollars missing. Canada's stock market just had the kind of day that makes investors look twice.

The S&P/TSX Composite Index, the Toronto Stock Exchange's main benchmark, closed at 35,620.03 on Friday, October 30, 2026 — down 629.00 points, or 1.735% (about 1.74%), from Thursday's 36,249.03.

And the damage started early.

The TSX opened at 36,049.56, its highest point of the day, before tumbling to 35,310.46. It recovered some ground before closing, but still finished at its lowest level of the week's five sessions.

Trading was unusually busy: approximately 322 million shares changed hands, compared with roughly 244 million on Thursday.

The Twist: October Was Still a Winning Month

Here's what Friday's red numbers don't tell you.

Despite the selloff, the TSX finished October up 1.09% for the month and remained up 12.32% so far in 2026.

One ugly trading session didn't erase the year's gains.

What a 1.74% Drop Means for Your Money

Suppose you had $50,000 invested in a portfolio that fell exactly 1.74%.

That would mean approximately $870 gone on paper in one day.

Not pleasant. But daily swings like this are part of stock-market investing.

Your actual experience depends on your investments. A TSX-tracking fund would generally move similarly to the index, while a portfolio containing bonds, cash or U.S. stocks could behave differently.

The Twikup Take

Friday delivered a painful reminder that markets don't climb in straight lines. The TSX lost 629 points in a single session, yet October and 2026 remained positive.

One bad Friday can shake your portfolio. It doesn't automatically change the bigger picture.
