Every Market Cycle Has a “Big Stock.” But the Real Clue Is Usually the Industry Group Behind It.
The market’s biggest winners rarely emerge alone. They are usually part of an industry group benefiting from a powerful new fundamental trend.
2023: AI Compute and Semiconductors
This marked the beginning of a new bull market and the emergence of the generative AI theme.
Big leaders:
$NVDA | Nvidia
$SMCI | Super Micro Computer
NVDA became the face of the cycle, but the leadership was much broader. Chips, servers, networking equipment, and the entire data-center buildout were beginning to move.
2024: AI Software, Data Platforms, and Power
Leadership expanded from companies building the AI infrastructure to those finding ways to monetize and support it.
Big leaders:
$PLTR | Palantir
$APP | AppLovin
AI adoption spread into software, data platforms, advertising optimization, networking, and power generation. The theme was evolving, but the underlying driver remained the same.
2025: Memory, Storage, and the AI Data Stack
The market’s attention shifted toward the next major bottleneck. AI systems required enormous amounts of high-performance memory, flash storage, and data-center capacity.
Big leaders:
$SNDK | SanDisk
$WDC | Western Digital
$STX | Seagate Technology
$MU | Micron Technology
These became some of the market’s biggest winners as demand for AI memory and storage accelerated.
2026: The Memory Supercycle Continues
Leadership continued into 2026 and semiconductors remerged as a leading group rather than transitioning into an entirely new theme.
Leaders:
$SNDK | SanDisk
$MU | Micron Technology
$STX | Seagate Technology
$WDC | Western Digital
But don’t overlook what happened outside the dominant AI theme.
Metals and mining also developed into a major winning group during this bull market period 2024-2026. The market can have one dominant secular story while still producing powerful leadership in completely different areas.
The next monster winner probably won’t be random.
It will likely emerge from a strengthening industry group with accelerating earnings and sales, increasing institutional sponsorship, elite Relative Strength, and a chart that refuses to break.
2023: AI compute and semiconductors
2024: AI software, data platforms, and power
2025–2026: AI memory, storage, semis
Meanwhile, metals and mining proved that major leadership can still emerge outside the market’s primary theme.
What industry group do you think becomes the next true market leader for 2026–2027?
