the Standard & Poor's 500 Full of global companies that have had great long-term investments. In this index, it's not difficult to find companies that have returned 20% or more annually to investors over the past decade.

Here I'll highlight two high-quality S&P 500 companies that I've recently built positions in and plan to hold for the long term. These stocks have been excellent investments recently and I'm backing them to significantly boost my retirement portfolio over the next decade.

Global transportation power

First, we have Uber (NYSE: Uber). It is the largest ride-sharing and food delivery company in the world.

I see a lot of growth potential here because this is a very scalable business. Over the next decade, I expect Uber to become much larger as it launches in new cities and offers new services (today it offers all kinds of services including courier services and plane/train/boat reservations).

Note that year-over-year revenue growth for Q3 2025 was 20%. So, the company is growing very fast today.

One thing that interests me here is the possibility of self-driving taxis. Currently, Uber has partnerships with more than 10 self-driving companies, and last month, it launched a partnership with Nvidia To accelerate the development of self-driving taxis.

Now, some people think so Teslaand its self-driving technology, poses a risk here. I'm not convinced about that although I think there is room for many more companies in this space.

I think the biggest threat is the job losses associated with AI and its impact on consumer spending. If a lot of people lose their jobs in the coming years, the travel industry will likely be affected, so this is an issue I will be monitoring.

But the outlook at the moment is attractive in my view. Trading on a forward-looking price-to-earnings (P/E) of around 25, I think this stock is worth a closer look.

A major player in cybersecurity

The other stock I want to highlight is… Crowd Strike (Nasdaq:CRWD). It is generally viewed as the leader in cybersecurity.

Over the next decade, I expect the cybersecurity industry to grow significantly. Today, no company can afford to take this area of ​​technology lightly – the risks are simply too high (e.g. downtime).

I see CrowdStrike as well-positioned to capitalize on the industry's growth. It offers a comprehensive cloud platform known as Falcon, which is designed to provide powerful protection for businesses.

It's worth noting that like Uber, CrowdStrike has just launched a partnership with Nvidia. The two companies will work together to develop durable AI cybersecurity agents that can protect data centers.

This stock has always been expensive (P/E ratio is around 150 today). But this did not prevent it from achieving impressive returns in the long term.

Over the past year, it has risen by almost 80%. Over the past 5 years, the price has risen approximately 285% (with a lot of volatility along the way).

The problem is that the company is still very small today (relative to other US tech companies). Currently, its market cap is only about $140 billion.

I think it can become much larger and is worth considering as a long-term investment. Competition from rivals and operational setbacks pose risks, but over the next five to 10 years, I think this stock will do well.
