5 Most Profitable Stocks of the Past 5 Years

Yahoo Finance ·

The semiconductor and cloud sectors are thriving on surging artificial intelligence demand, with key players like NVIDIA, Micron, SK hynix, and TSMC capitalizing on advanced chip manufacturing and computing needs. Meanwhile, Amazon, Microsoft, and Alphabet are generating substantial revenue from digital infrastructure, though expanding capacity demands massive capital. According to Reuters, S&P 500 second-quarter earnings for 2026 were on track to surge 52% year-over-year, driven by a 74% jump in the technology sector. However, reported net income does not always equate to recurring operational profitability. For instance, Amazon included $53.4 billion in non-operating pretax income tied to its Anthropic investment in Q2, and aggressive AI infrastructure spending dragged its trailing 12-month free cash flow into negative territory at negative $7.6 billion. Similarly, Berkshire Hathaway (NYSE:BRK-B) doubled its net earnings in Q2 2026, though nearly half stemmed from investment gains rather than core business operations, highlighting the nuance behind cumulative net income metrics.

The semiconductor and cloud computing industries achieved record profitability over the past five years driven by expanding AI demand. Notably, S&P 500 companies' Q2 2026 earnings are projected to surge 52% year-over-year, boosted by a 74% spike in the tech sector. However, caution is warranted as massive infrastructure investments and net income including non-operating investment valuation gains may diverge from actual operating profitability.

DYAX 전담 분석

While revenues of semiconductors and Big Tech are soaring due to AI infrastructure expansion, massive capital expenditures are increasing financial burdens, as seen in Amazon's free cash flow deficit of $7.6 billion. In particular, since a significant portion of Q2 earnings relies on non-operating investment valuation gains, the difference between simple net income and actual operating profitability must be meticulously analyzed.

The bull case is the continuous conversion of cloud backlogs and AI semiconductor demand into sustained operating profits, while the bear case is deteriorating cash flow and valuation pressure relative to excessive capex. Investors should monitor free cash flow and recurring operating margins as key metrics.
