I tracked 15 investment themes against the S&P 500- here's who's winning, who's bleeding, and what it actually means for 2026

I've been tracking 15 investment themes for a while now and honestly the gap between what people talk about and what's actually performing is pretty wild this year. Pulled equal-weight basket data on all of them against SPY, which is sitting at −4% YTD as of early April 2026 and the results tell a very different story than the headlines.

The leaderboard (YTD average return, equal-weight)

|Theme|YTD Avg|% of Stocks Beating SPY| |:-|:-|:-| |Oil & Gas|+32.9%|100% (28/28)| |Data Center & AI Infra|+19.5%|75%| |Space & Satellite|+19.1%|65%| |Gold & Precious Metals|+14.3%|92%| |Defense & Military|+3.3%|61%| |Robotics & Automation|+1.9%|48%| |Nuclear Energy|−1.7%|61%| |Biotech & Healthcare|−4.9%|35%| |Renewable Energy|−5.8%|48%| |EV|−9.5%|35%| |Cybersecurity|−12.0%|22%| |Crypto|−14.8%|20%| |AI|−15.8%|17%| |Fintech|−17.2%|21%| |Quantum Computing|−20.4%|14%|

SPY benchmark: −4.0% YTD.

Five things this data actually tells you

1. The rotation into physical assets is real and broad

Oil & Gas has 100% breadth - every single one of 28 stocks is beating SPY. That almost never happens. Gold has 92% breadth. These are also the two lowest-beta themes in the set (0.71 and 0.86). The market isn't just buying safety - it's pricing in sustained inflation risk and dollar skepticism at the same time. When breadth is this wide, it's a macro regime signal, not a sector rotation.

2. "AI infrastructure" and "AI" are two completely different trades

This is the one that surprised me most. The AI theme basket (chips, software, platforms) is down −15.8% YTD with only 5 of 30 stocks beating SPY. Meanwhile, Data Center & AI Infrastructure (power, cooling, REITs, networking) is up +19.5% with 18 of 24 stocks ahead of the market. Same underlying megatrend, completely different performance. The physical layer - signed contracts, locked-in capacity, power purchase agreements - is beating the narrative layer by 35 percentage points YTD. The market is paying for certainty right now, not optionality.

3. Fintech and Cybersecurity have a breadth problem that the headlines hide

Both are constantly described as high-growth, essential themes. Both have terrible equal-weight returns over the past year - Fintech basket up only +8.5%, Cybersecurity up +9.8%, both lagging SPY's +30% by a wide margin. Less than 22% of stocks in either theme are beating SPY YTD. The issue: both themes are cap-heavy. The top 3–5 names absorb almost all the institutional flows, while the rest of the basket quietly underperforms. If you're buying "the cybersecurity theme" through a broad ETF or randomly picking names, the data says the odds are not in your favor.

4. Crypto had an incredible year - then 2026 hit

Over the trailing 12 months, the equal-weight Crypto basket returned +146.2%. Second only to Gold's +152.9%. But YTD in 2026, it's down −14.8% with only 4 of 20 stocks ahead of SPY. Beta 2.00 - highest in the universe. This is the post-halving cycle playing out exactly as history suggests: big run-up through the halving, followed by a digestion period while the next catalyst is awaited. The regulatory story (Coinbase's OCC trust charter progress, stablecoin legislation) is the near-term thing to watch, but the short-term momentum is clearly negative.

5. Quantum Computing is 95% Big Tech with a quantum label on it

The top 5 stocks in the Quantum basket represent 95% of combined market cap - NVDA, GOOGL, AMZN, IBM, INTC. These companies have quantum programs, but quantum is essentially immaterial to their earnings. The pure-play names (IONQ, QBTS) are down −37% to −49% YTD. The basket average is −20.4% with only 2 of 14 stocks beating SPY. If you're buying quantum as a theme, you're mostly just buying mega-cap tech at a premium narrative valuation.

Why thematic investing actually matters (done right)

The instinct to invest thematically isn't wrong - it's just often executed badly. The value isn't in buying a random ETF because a theme sounds exciting. It's in understanding where in the value chain the money is actually flowing, how broad the move is (5 stocks carrying a basket is very different from 25 stocks moving together), and what the macro backdrop is doing to risk appetite within each theme.

The breadth number is underrated. A theme with 90%+ breadth is telling you something real. A theme where 3 names are up and 27 are down is telling you the narrative is concentrated, not durable.

Valuation matters too. Some of the worst-performing themes YTD - AI, Fintech, Quantum - are also the ones where 2021-era multiples never fully reset. High-growth narratives can survive for a long time on momentum, but the unwind tends to be sharp when macro conditions shift toward rewarding tangible cash flows over future optionality.

I've built a theme tracker that pulls updated performance data, news, and stock-level intelligence across all 15 themes every single day - if this kind of analysis is useful, you can check it out at vcpscanner.com/themes
