A couple of years ago, we were at a point where the stock markets were experiencing a pretty interesting recovery. I remember that at the end of January 2024, the entire economic context pointed to central banks finally lowering interest rates, inflation had already decreased significantly, and that generated a particular optimism among investors. In that scenario, some solid stock recommendations emerged that were worth analyzing in detail.

What caught my attention most then was how the technology sector, especially everything related to artificial intelligence, was positioning itself as the market driver. Alphabet, for example, was experiencing an impressive expansion moment. The company controlled more than 80% of the digital advertising market through Google and YouTube, and with the launch of Gemini, its AI model, it aimed to compete directly with ChatGPT. Its free cash flow of over $77 billion gave it a tremendous financial strength to innovate. Compared to its competitors in the group of the Seven Magnificent, its P/E ratio hovered around 29, quite more attractive than the sector average, which exceeded 35.

Nvidia was another fascinating case. It dominated nearly 90% of the AI chip market, an almost unreachable position. After growing 239% in 2023, it continued with an impressive bullish momentum. Its GPUs were essential for any company wanting to play in the AI game, from gaming to automotive. It was hard not to see it as a winning bet in that context.

Then there was Novo Nordisk, operating in a completely different but equally promising market. The obesity medication sector was booming. In the United States, 73% of adults suffered from overweight or obesity, and projections indicated that this market would reach $44 billion by 2030. With Ozempic as its star product, Novo Nordisk was perfectly positioned to capture that growing demand. Its financial numbers were solid: 29% sales growth and 47% profit increase during the first nine months of 2023.

Berkshire Hathaway represented something different: pure stability. Warren Buffett had accumulated $157 billion in cash on the balance sheet, giving him incredible flexibility to move in volatile markets. Its beta of 0.64 meant it experienced less fluctuation than the overall market. It was the choice for those seeking to sleep peacefully.

Broadcom, for its part, was in a moment of transformation. After growing 108% in 2023, the acquisition of VMware was a strategic move that took it beyond semiconductors into enterprise software. That reduced its dependence on the chip cycle and diversified its sources of income. For 2024, they projected a 40% revenue growth.

Now, the question was always how to invest in these stock recommendations. There were two main paths. For those looking to play short-term, CFDs offered an interesting tool. They allowed speculation on price movements without physically owning the assets, and provided leverage. But of course, that also amplified losses. Geopolitical events, central bank decisions, U.S. presidential elections—all of that generated volatility that short-term traders tried to capitalize on.

For the rest, for those of us thinking medium and long term, the approach was different. You had to choose a regulated broker, do a serious analysis of each company's fundamentals, diversify across sectors, and keep a cool head when markets got nervous. Diversification was key: not concentrating on a single stock but spreading risk among several companies from different sectors. Combining stocks with other asset types also helped stabilize the portfolio.

In retrospect, those five companies we selected back then covered interesting spectrums: pharmaceutical with Novo Nordisk, technology and AI with Nvidia and Alphabet, financial with Berkshire Hathaway, and semiconductors with Broadcom. It was a fairly balanced portfolio for someone patient enough to wait years.

What I learned from that analysis was that in 2024, as in any year, the important thing was to understand the macro context, identify structural trends like AI, and select companies with solid fundamentals and strong competitive positions. The long-term stock recommendations are the ones that understand where the money is flowing in the real economy, not those that simply seek quick gains.
