Key Takeaways
- The Themes Cybersecurity ETF (ticker SPAM) returned 27.5 % from year‑end 2025 to June 5 2026, more than three times the S&P 500’s 8.2 % gain over the same period.
- A $10,000 investment in SPAM grew to roughly $12,750, while the same amount in the SPDR S&P 500 ETF (SPY) reached about $10,820.
- SPAM’s outperformance is driven by a surge in AI‑related capital expenditures and parallel growth in cyber‑threats, positioning its 36‑stock portfolio as a dual beneficiary of both offense and defense spending.
- Most of the ETF’s 2026 gain came in the last month (+14.6 %), showing concentrated momentum that can reverse quickly if the AI capex narrative falters.
- Risks include a potential pull‑back in hyperscaler capex, weaker billings/ARR from major holdings (CrowdStrike, Palo Alto Networks), and a broader unwind of AI‑linked investments, which could trigger sharp drawdowns in this narrowly‑focused, $2.4 million‑AUM fund.
Performance Overview
From December 31, 2025 to June 5, 2026, the Themes Cybersecurity ETF (NASDAQ:SPAM) climbed from $30.65 to $39.09, delivering a total return of 27.54 %. In contrast, the SPDR S&P 500 ETF Trust (NYSEARCA:SPY) rose only 8.16 % over the identical window, moving from $681.92 to $737.55. The ETF’s gain is therefore more than three times that of the broad market, turning the ticker’s ironic association with spam email into a genuine outperformance story.
Dollar‑Impact Illustration
If an investor had placed $10,000 into SPAM at the end‑of‑year 2025 price, the holding would be worth approximately $12,750 by June 5, 2026. The same $10,000 invested in SPY would have grown to about $10,820. The difference—roughly $1,930—could cover a used car versus a tank of gas, highlighting how the cybersecurity fund’s performance translates into tangible wealth differences for investors.
Recent Turnaround from Laggard to Leader
As recently as February 10, 2026, SPAM had returned only 19.4 % since its December 2023 launch, lagging behind the S&P 500 and holding a modest $2.4 million in assets under management. Top names such as CrowdStrike and Palo Alto Networks were dragging the fund down. Four months later, the same ETF is posting the strong numbers that investors now screenshot, illustrating how quickly sentiment and fundamentals can shift within a thematic basket.
Mechanism Behind the Outperformance
SPAM tracks the Solactive Cyber Security Index, holds 36 cybersecurity stocks, and charges an expense ratio of 0.35 %. The real engine, however, is the macro backdrop: AI‑driven capital expenditures are at multi‑year highs, with Vanguard forecasting a 7.0 % baseline growth rate for corporate capex through 2026—well above the 3.8 % pace of 2023‑24. A substantial portion of that spending goes into infrastructure that must be defended. Simultaneously, threat actors are leveraging the same generative AI tools to craft more convincing phishing campaigns, automate intrusions, and scan networks at scale. When both offense and defense are buying more compute, cybersecurity vendors capture revenue from both sides of the trade.
Analyst Views and Macro Catalysts
Research firms are echoing this dual‑benefit thesis. Zacks projects cybersecurity spending to expand at a 13.8 % CAGR from 2026 to 2034, reaching $699.39 billion, citing AI adoption and rising geopolitical tensions. Goldman Sachs highlights “economic security” as a 2026 theme, linking NATO defense commitments, reindustrialization, and supply‑chain resilience to heightened cyber demand. In this view, the ETF’s holdings—CrowdStrike, Palo Alto Networks, Fortinet, Akamai, and peers—are being re‑priced as durable beneficiaries of the AI capex cycle rather than as discretionary IT line items vulnerable to budget cuts.
Momentum Characteristics
The bulk of SPAM’s 2026 advance occurred late in the period: the fund rose 14.61 % in the final month alone, moving from $34.10 on May 6 to $39.09 on June 5. Over the same one‑month span, the S&P 500 returned roughly 0.5 %. Such a concentrated surge suggests either a belated market recognition of the cybersecurity thesis or a fresh catalyst reinforcing an existing belief. Technical commentary in late May, including a Stock Traders Daily note on May 29 citing a sustained breakout and limited resistance above current prices, supports the latter interpretation.
Recent Volatility and Risk Profile
Despite the strong run, SPAM showed signs of pull‑back, declining 2.56 % over the last week and posting a 4.44 % drop on June 5 itself. This pattern—sharp monthly gains followed by a few percent retracement—is typical for concentrated thematic ETFs, where price swings reflect both conviction and vulnerability to narrative shifts. Investors should view the volatility as part of the price of admission for exposure to a niche, high‑conviction sector.
Forward‑Looking Indicators
The sustainability of SPAM’s edge hinges on three key data streams: (1) quarterly capex guidance from hyperscalers (Amazon, Microsoft, Google, etc.), (2) billings and net new ARR releases from major holdings such as CrowdStrike and Palo Alto Networks, and (3) the Bureau of Economic Analysis private fixed‑investment series that underpins Vanguard’s 7.0 % capex forecast. If these metrics continue to trend upward, the mechanism that powered the outperformance remains intact. Conversely, any roll‑back in AI‑linked spending, weaker-than‑expected sales from cybersecurity leaders, or a broad unwind of AI investments could trigger a rapid reversal, erasing the gains as quickly as they were accrued.
Investment Takeaway
Buying SPAM today amounts to taking a bet on the next print of those three indicators rather than on the past rally. The ETF offers compelling exposure to a sector sitting at the intersection of AI expansion and heightened cyber risk, but its narrow focus and modest AUM make it susceptible to sharp drawdowns if the macro thesis falters. Investors should weigh the potential for continued outperformance against the inherent volatility of a concentrated, theme‑driven fund.
