Apple Inc. (AAPL  ) stock has already outpaced the broader market in 2026. The question now is whether history - and a revamped Siri - can help it stay that way. Apple stock is up 16.1% year-to-date, ahead of the S&P 500's 11.2% gain. With the company's Worldwide Developers Conference (or WWDC) kicking off next week, Wall Street is increasingly focused on whether Apple can finally deliver the artificial intelligence upgrades it first promised investors nearly two years ago.

According to JPMorgan analyst Samik Chatterjee, WWDC could mark the beginning of a catalyst-rich stretch that extends well beyond software announcements and into Apple's fall hardware launch cycle.

Siri 2.0 Takes Center Stage

The centerpiece of this year's WWDC is expected to be a major overhaul of Siri.

Chatterjee expects Apple to unveil a chatbot-style Siri experience, a new "Search or Ask" interface, deeper on-screen awareness and personal context capabilities, and more advanced agentic features that can complete tasks across apps. The analyst also expects Apple to expand external AI model integrations beyond ChatGPT, potentially transforming Siri into a broader AI distribution platform.

For investors, the significance goes beyond feature upgrades. Apple has faced criticism for appearing behind rivals in the AI race, and a more capable Siri could help change that narrative while laying the groundwork for future hardware and services growth.

Apple's Favorite Time Of Year?

The AI story may be arriving at an opportune moment.

JPMorgan notes that Apple shares have historically outperformed the broader market in the months leading up to September product launches, with average outperformance of roughly 11% versus the S&P 500 over the last decade. The firm expects excitement around AI enhancements, combined with anticipation for new hardware categories such as a foldable iPhone and a touch-screen Mac, to support a similar setup this year.

The stock's technical picture suggests investors may already be positioning for that possibility. Apple shares recently pushed to fresh highs and continue to trade above key moving averages, while momentum indicators remain constructive despite approaching overbought territory.

Whether Siri 2.0 ultimately lives up to expectations remains to be seen. But with Apple already beating the market, a favorable seasonal backdrop, and one of its most closely watched WWDC events in years approaching, investors may be wondering if the company's next rally is just one "Hey Siri" away.
