As the Q3 earnings season comes to a close, it’s time to take stock of this quarter’s best and worst performers in the auto parts retailer industry, including Genuine Parts (NYSE:GPC) and its peers.

Cars are complex machines that need maintenance and occasional repairs, and auto parts retailers cater to the professional mechanic as well as the do-it-yourself (DIY) fixer. Work on cars may entail replacing fluids, parts, or accessories, and these stores have the parts and accessories or these jobs. While e-commerce competition presents a risk, these stores have a leg up due to the combination of broad and deep selection as well as expertise provided by sales associates. Another change on the horizon could be the increasing penetration of electric vehicles.

Market Update

Thanks to the Fed’s rate hikes in 2022 and 2023, inflation has been on a steady path downward, easing back toward that 2% sweet spot. Fortunately (miraculously to some), all this tightening didn’t send the economy tumbling into a recession, so here we are, cautiously celebrating a soft landing. The cherry on top? Recent rate cuts (half a point in September, a quarter in November) have kept 2024 stock markets frothy, especially after Trump’s November win lit a fire under major indices and sent them to all-time highs. However, there's still plenty to ponder — tariffs, corporate tax cuts, and what 2025 might hold for the economy.
