TSX Hits Record Highs – Why Suncor’s Cash Flow and Buybacks Make It a Stock to Watch

The S&P/TSX Composite Index hit a new record closing high this month, building on a streak that saw it complete its eighth consecutive quarterly gain back in June — the longest winning run in 30 years. With the benchmark now firmly above the 36,000 level, market sentiment remains buoyant. But with the index at historic highs, the question investors truly need to ask has shifted: at these levels, what kinds of stocks offer both a margin of safety and upside potential?

The answer may not be overly complicated — companies that consistently generate real cash flow and use it to meaningfully enhance per-share value through buybacks are far more reliable than those driven solely by hype or sentiment. Suncor Energy (TSX:SU) stands out as a textbook example of this approach.

Record Cash Flow, Accelerating Buybacks

Suncor’s business model spans upstream production, downstream refining, and a retail network operated through its Petro-Canada gas stations — a vertically integrated structure that provides a natural hedge: when crude prices weaken, refining margins often offer a buffer, helping to smooth overall earnings volatility. This integrated approach delivered powerful results in the latest quarterly report: adjusted funds from operations (AFFO) reached a record-tying C$5.3 billion in the second quarter, while free funds flow climbed to an all-time high of C$4.0 billion.

Rather than sitting on this cash pile, management has stepped up its share repurchase program significantly, increasing monthly buybacks to C$500 million starting in August. Based on the current share price of approximately C$89.05 and roughly 1.18 billion shares outstanding, maintaining this pace would retire about 67.4 million shares over a full year, reducing the total share count by approximately 5.7%. The core value of buybacks lies in their compounding effect: even if total profits remain flat for a period, earnings per share (EPS) rise naturally as the denominator shrinks, increasing the ownership stake of long-term holders over time.

Buyback Period Cumulative Investment Estimated Shares Repurchased Estimated Share Base Reduction
1 month C$500 million 5.6 million 0.5%
3 months C$1.5 billion 16.8 million 1.4%
6 months C$3.0 billion 33.7 million 2.9%
12 months C$6.0 billion 67.4 million 5.7%

Reasonable Valuation, but Risks Remain

At around C$89 per share, Suncor trades at roughly 12 times trailing earnings. In a market where growth stocks often command multiples in the dozens, this valuation appears relatively modest. That said, it hardly counts as a bargain-bin price — the stock has already enjoyed a significant run over the past year, and the current valuation already reflects, to a considerable extent, market optimism around operational improvements and the buyback program.

The real wildcard remains commodities themselves. A sharp drop in crude prices would directly hit upstream cash flow, while narrowing refining margins could erode the downstream buffer. Maintenance issues, rising carbon costs, and project execution risks could also interrupt what has been an impressive operational streak. For these reasons, even with Suncor’s solid fundamentals, investors should avoid making it their sole holding. Instead, it deserves a place within a well-diversified portfolio that spreads exposure across sectors to mitigate the inherent volatility of commodity cycles.

Stock Selection in a High Market

When the index no longer offers a “free lunch,” stock selection must evolve from simply riding the wave to finding self-sustaining drivers of value. Suncor’s case illustrates that large-scale buybacks, backed by strong cash flow, can generate value for shareholders through steady EPS growth without relying on continued market upside. For investors seeking a balance of defense and offense in a high-market environment, this type of stock deserves a closer look — but proper position sizing and risk diversification remain essential prerequisites.
