Growth Comparison of the Companies (2020–2024)
Summary and Concrete Investment Tips
The tech sector remains one of the most exciting for investors in 2025. The four companies — Apple, Microsoft, Nvidia, and SAP — represent different tech trends and business models. Each has its own strengths and weaknesses, and depending on your investor profile, a different strategy may be suitable.
Apple: Stability with Growth Potential
Apple remains a safe bet for defensive investors. Despite its heavy reliance on the iPhone and slow hardware innovation, Apple offers a strong brand, a stable market position, and growing service revenue. Investors seeking long-term stability and moderate returns will find Apple to be a solid choice.
Microsoft: Cloud Leader with AI Future
Microsoft remains unmatched in cloud dominance and benefits greatly from AI integration in Office and Azure. Although the valuation is high, the company’s stable growth and broad customer base make it a top choice for growth-oriented investors who aren’t too risk-seeking.
Nvidia: The AI Champion with Volatility
Nvidia remains the biggest winner of the AI revolution. Demand for powerful chips for data centers and autonomous driving is driving growth. However, the valuation is already high, and the company is heavily dependent on exports and chip demand. Aggressive investors with a higher risk profile can expect high returns, but also high volatility.
SAP: The Underrated Software Giant
SAP may not be the most exciting player in the tech space, but it’s particularly interesting for value-oriented investors. With a low valuation, stable cash flows, and an ongoing cloud transformation, SAP offers long-term potential — especially in a volatile market environment.
Concrete Investment Tips
- Defensive Investors: Focus on stable dividends and low volatility. Apple is the best choice.
- Growth-Oriented Investors: Go for consistent revenue growth and long-term prospects. Microsoft offers the perfect mix of safety and AI growth.
- Aggressive Investors: Take on risk and invest in the future of AI infrastructure. Nvidia remains the leading chipmaker with high upside potential.
- Value-Oriented Investors: Look for undervalued companies with strong earnings. SAP offers an attractive valuation level.
Diversification Tip: Tech Mixed Portfolio
For investors who don’t want to commit to a single company, a diversified tech portfolio may be wise. A possible allocation could look like this:
- 30% Microsoft (Cloud & AI)
- 25% Apple (Stability & Services)
- 25% Nvidia (Growth & Hardware)
- 20% SAP (Value & Transformation)
This portfolio combines stability, growth, and valuation advantages and is well-suited for long-term investors.
Warning Against Overvaluation
Especially for Nvidia and partly for Microsoft, investors should proceed with caution. High valuations imply high growth expectations, which may not always be met. It is advisable to enter such positions gradually and take profits regularly.
Outlook: Tech Trends and Beyond
The megatrends Artificial Intelligence, Cloud Computing, Autonomous Driving, and Digital Transformation will remain key themes in the coming years. Apple, Microsoft, Nvidia, and SAP are all active in these areas, with varying degrees of strength. Companies that can adapt their business models flexibly to new requirements will be the winners in the years ahead.
Those investing in tech should look beyond current performance and focus on strategic positioning, innovation capacity, and long-term growth potential. 2025 is a great year to clarify your investment strategy and invest purposefully in the future of technology.
