The Rise of High-Performing Stocks in the Scottish Mortgage Portfolio
Over the past year, shares of the Scottish Mortgage Investment Trust (LSE: SMT) have experienced a remarkable surge, climbing by approximately 25%. This impressive growth has drawn attention to the trust’s portfolio, which includes some of the most dynamic and high-performing stocks in the market. In this analysis, we will explore three standout holdings that have contributed significantly to the trust’s success.
Nvidia: A Market Leader in AI Chipmaking
One of the most prominent names in the portfolio is Nvidia (NASDAQ: NVDA), a leading manufacturer of artificial intelligence (AI) chips. Since the start of April, its shares have surged by 83%, propelling the company’s market capitalisation to an astonishing $4.22 trillion. For context, this valuation is nearly 20 times the size of HSBC, the UK’s largest listed firm.
The recent milestone of reaching a $4 trillion valuation was driven by news that the US government has permitted Nvidia to export modified H20 AI chips to China. This decision came as part of broader trade negotiations involving rare earth metals. Major tech companies such as Tencent and ByteDance are reportedly eager to acquire these chips, indicating strong demand.
Despite the positive momentum, there are concerns about the sustainability of Nvidia’s current pricing power. Tom Slater, the manager of Scottish Mortgage, has highlighted the risk of commoditisation in the AI sector. He noted that if AI becomes widespread, it may lead to lower profit margins. As a result, the trust has been gradually reducing its stake in Nvidia, although it remains one of the top 10 holdings as of June.
Joby Aviation: Pioneering the Future of Air Travel
Another standout performer in the portfolio is Joby Aviation (NYSE: JOBY), a company at the forefront of developing flying air taxis. Since April, its stock has increased from $5 to $17, marking a staggering 240% gain. This growth has been supported by successful trials of its aircraft in Dubai, with plans to launch services in early 2026. The company also intends to expand its operations globally, including markets in the US, UK, and Japan.
In addition, Joby recently announced that it will double its manufacturing capacity, allowing it to produce up to 24 aircraft per year. This expansion is expected to support its ambitious growth targets and increase its ability to meet rising demand for air taxi services.
Roblox: Revolutionising the Gaming Industry
The third notable holding is Roblox, a global gaming platform that has seen its shares more than double year-to-date. The company recently launched a new intellectual property licensing platform, enabling brands like Netflix, Sega, and Lionsgate to integrate their characters and worlds into the Roblox ecosystem. This move has the potential to drive significant engagement and revenue growth for the platform.
However, despite its strong performance, Roblox faces challenges. Its current valuation is high, and any missteps in revenue growth could lead to sharp declines in its stock price. Investors should remain cautious when considering exposure to such a speculative asset.
Considerations for Investors
While the performance of these stocks has been impressive, investors must weigh the risks associated with each. Joby Aviation, for example, has a market capitalisation of $14.5 billion but currently generates no revenue, making it a highly speculative investment. Similarly, Roblox’s valuations are steep, and any disappointment in its financial performance could lead to severe market corrections.
For those seeking exposure to these high-growth stocks, along with over 95 others in the Scottish Mortgage portfolio, the trust itself may offer a viable option. Although the trust trades at a 10% discount to its net asset value, the overall portfolio of growth companies remains strong. However, there is a risk that this discount could widen further, depending on market conditions.
Investors should carefully evaluate their risk tolerance and investment goals before making any decisions. While the future of AI, air travel, and gaming looks promising, the path to success is not without its challenges.
