Looking back at 2024, that year was quite interesting for anyone paying attention to the stock market. At the start of that year, the indices were in a clear bullish phase, with inflation falling and central banks beginning to talk about possible rate cuts. In that context, there were some truly solid options if you knew where to look. Personally, the best companies to invest in during 2024 that I saw back then were a pretty diverse mix.

Alphabet was one of the ones that caught my attention the most. At the time, the company was growing by around 58% year over year, and the launch of Gemini gave it a major boost in the AI race. With more than 77 billion in free cash flow, it had plenty of financial muscle. The interesting part was that its P/E was around 29—lower than the sector average, which was above 35. That meant there was room for growth versus competitors like Meta or Tesla.

Nvidia was practically unavoidable in any conversation about technology in 2024. It dominated the AI chip market with nearly 90% market share. Its shares had risen 239% in 2023 and the bullish trend continued into 2024. Technical analysis showed sustained momentum, with the stock trading above its moving averages. It was a safe bet if you believed in AI growth.

Novo Nordisk was different, but equally interesting. Here we’re talking about the pharmaceutical and obesity sector. In 2023, it grew 57%, and in 2024 it kept the trend going. The market for anti-obesity drugs was projected to reach 44 billion by 2030. With Ozempic as its flagship product, they were well positioned. They also diversified into other areas such as Alzheimer’s disease and sickle cell diseases.

Berkshire Hathaway offered something more conservative. Under the direction of Warren Buffett, the company had 157 billion in cash. Its beta of 0.64 meant it fluctuated less than the overall market, making it attractive for people looking for stability. In 2023, it grew 25%—not spectacular, but solid.

Broadcom rounded out the group with 108% growth in 2023 and an additional 11.48% so far in 2024. The acquisition of VMware was a strategic move that diversified its business beyond semiconductors. They projected 40% revenue growth for fiscal 2024 after the integration.

If you wanted to trade short term in 2024, CFDs offered flexibility. You could speculate on price moves without owning the underlying assets, taking advantage of volatility driven by central bank decisions, geopolitical conflicts, or elections in the U.S. That said, CFDs amplify both gains and losses, so they required discipline and well-placed stop-loss orders.

For medium- and long-term investing, the strategy was different. The key was to choose companies with strong fundamentals, stable projections, and not to get swept up by short-term volatility. Diversification was essential: spreading your investment across multiple sectors and companies rather than betting everything on just one. Those five companies I mentioned covered technology, pharmaceuticals, finance, and semiconductors, so they provided a reasonable balance.

Looking back from 2026, the best companies to invest in during 2024 were really the ones that combined strong fundamentals with exposure to long-term trends like AI and demographic changes. It wasn’t about chasing quick profits—it was about understanding where the market was headed. That year was crucial for making strategic decisions aligned with real global trends, not passing hype.
