PepsiCo shares are down 10% year-to-date in 2026, even as the S&P 500 index has climbed 13% over the same stretch. The widening gap has put the stock among the more notable underperformers in the consumer staples sector this year.

The explanation offered centers on PepsiCo falling behind a key competitor rather than any single company-specific shock. For income-focused investors, the stock's dividend profile remains a point of interest even as the share price lags, since several dividend-stock roundups continue to name PepsiCo among candidates worth holding.

What remains unresolved is whether the underperformance reflects a temporary rough patch, as some coverage frames it, or a more structural competitive slippage that will keep weighing on the stock beyond 2026.
