TMX Group has more than doubled shareholders' money over the past five years, yet the stock now screens as relatively expensive on broader valuation checks. For anyone looking at the recent run, the question is whether current pricing already bakes in most of the good news.
- The share price has delivered a 110.1% gain over 5 years, which suggests long term holders have already captured a substantial return from TMX Group.
- Future fee income and trading related revenue can support today’s pricing if activity remains healthy, while any sustained drop in volumes or listings would put pressure on what investors are currently willing to pay.
- The company scores in just 1 of 6 valuation checks on Simply Wall St’s model, which indicates TMX Group does not look like a clear bargain on the broader measures used in that framework.
The issue now is whether that strong five year record leaves enough upside potential at today’s valuation for new capital going into TMX Group.

Does TMX Group Look Pricey on Earnings?
P/E is a useful lens for TMX Group because earnings tend to track the health of its trading and listing activity. On that measure, the stock trades on about 24.2x earnings, which is well above the broader capital markets industry average near 6.4x and also ahead of the peer group at roughly 18.3x.
The Simply Wall St model suggests a fair P/E of about 20.8x for TMX Group once factors such as profitability, risk profile and size are brought into the same frame. The current multiple sits a few turns higher than that reference point, which implies investors are already paying a premium relative to what this framework would usually attach to the business.
On this P/E yardstick, TMX Group stock appears overvalued compared with both its tailored fair multiple and its sector benchmarks.

The Bottom Line
TMX Group now trades on a richer P/E than both its sector and the tailored fair multiple, so the market is already paying up for the story. The broader checks point to an overvalued read, which means fresh money is relying on that premium staying intact rather than narrowing. The real swing factor from here is whether trading activity and listings remain strong enough to support both current earnings and the elevated multiple investors are currently accepting.
