Strategic Portfolio Reallocation: Navigating Tech Rotation and Defense Rebalance in a Shifting Geopolitical Landscape

The global investment landscape is undergoing a subtle but significant realignment. As artificial intelligence (AI) leaders like NVIDIA face profit-taking pressures and valuation corrections, defense stocks such as Leonardo SpA are emerging as compelling hedges against geopolitical uncertainties. This shift reflects a broader recalibration of risk and reward in a world where technological progress and geopolitical tensions are inextricably linked. For investors, the challenge lies in balancing exposure to high-growth tech sectors with the stability of defense plays, which are increasingly positioned to benefit from sustained global defense spending.

The Tech Sector: Profit-Taking and Rotational Risks

NVIDIA (NVDA), the poster child of the AI revolution, has seen its stock surge by 4% in the past week, driven by optimism around OpenAI's GPT-5 launch and Sam Altman's public endorsements of the company's hardware. Yet, this momentum has also attracted profit-taking, with the stock trading near its 52-week high of $184.48. Analysts from Piper Sandler, Mizuho, and Wells Fargo have raised price targets to $192–$225, underscoring confidence in NVIDIA's dominance in AI infrastructure. However, the recent volatility—marked by overnight trading on the Blue Ocean ATS and elevated options activity—signals growing caution.

The company's financials remain robust, with a 69% year-over-year revenue jump to $44 billion and net margins exceeding 50%. Yet, the market is pricing in risks: regulatory scrutiny over AI chip exports to China, potential normalization of trade tensions, and the cyclical nature of tech investing. These factors, combined with a 26% year-to-date gain, suggest that short-term corrections are likely. Investors must weigh NVIDIA's long-term potential against near-term volatility, particularly as earnings reports and regulatory developments loom.

Historical backtesting reveals that NVIDIA's performance near resistance levels has been mixed. While the stock has occasionally surged past resistance—achieving a maximum return of 148.93% over 274 days when breakthroughs occurred—periods of consolidation and decline have also been common. This inconsistency underscores the importance of caution: resistance levels, while occasionally predictive, are not reliable indicators of future performance. Investors should consider reducing exposure or employing hedging strategies (e.g., covered calls) as the stock approaches key resistance points, given the elevated risk of short-term corrections.

The Defense Sector: A Geopolitical Hedge

While tech stocks face rotational pressures, defense companies like Leonardo SpA (LDO.MI) are gaining traction as geopolitical tensions persist. Italy's Leonardo, a key player in aerospace and defense, derives 83% of its revenue from defense contracts, positioning it to benefit from Europe's accelerated modernization efforts. With a €8.6 billion order backlog and a 13.5% year-on-year revenue increase in Q1 2025, the company is capitalizing on NATO's push for increased defense spending.

Leonardo's exposure to major programs—such as the Eurofighter Typhoon, F-35 Lightning II, and the tri-nation GCAP fighter jet initiative—ensures long-term visibility. Its joint venture with Rheinmetall to produce main battle tanks further diversifies its product portfolio. However, the company is not without risks. Geopolitical escalations in the Middle East and Europe could disrupt operations, while supply chain complexities and regulatory hurdles (e.g., ITAR compliance) pose operational challenges.

Morningstar's analysis highlights Leonardo's 4-star rating and a 28% discount to its estimated fair value of €42.40, suggesting undervaluation. The company's narrow economic moat, strong R&D capabilities, and disciplined dividend policy (1.5% yield) make it an attractive hedge against tech sector volatility. Yet, investors must remain vigilant about geopolitical de-escalation risks, which could dampen defense spending in the medium term.

Strategic Reallocation: Balancing Growth and Stability

The interplay between tech and defense sectors demands a nuanced approach. For investors, the key is to allocate capital in a way that mitigates near-term risks while capturing long-term growth. Here's how to position a portfolio:

1. Tech Sector Exposure with Hedging: Maintain a core position in AI leaders like NVIDIA but reduce exposure as the stock approaches key resistance levels. Use options strategies (e.g., covered calls or protective puts) to hedge against volatility.
2. Defense Sector Diversification: Allocate a portion of the portfolio to under-owned defense plays like Leonardo SpA. These stocks offer downside protection during tech rotations and benefit from structural tailwinds in global defense spending.
3. Geopolitical Scenario Planning: Monitor developments in conflict zones (e.g., Israel-Palestine, Russia-Ukraine) and regulatory shifts (e.g., U.S. export controls). Adjust allocations based on the likelihood of escalation or de-escalation.

Conclusion: A Dual-Track Strategy for Uncertain Times

The current market environment demands a dual-track strategy: leveraging the transformative potential of AI while hedging against geopolitical and regulatory risks. NVIDIA's dominance in AI infrastructure is unlikely to wane, but its valuation requires careful management. Meanwhile, Leonardo SpA's role in the defense sector offers a counterbalance, particularly as global tensions drive sustained demand for military modernization.

Investors who adopt a balanced approach—combining growth-oriented tech bets with defensive defense allocations—will be better positioned to navigate the volatility of the coming months. As the lines between technology and geopolitics blur, strategic reallocation will remain a cornerstone of resilient portfolio management.
