In recent months, analysts have increasingly noted signs of overheating in global financial markets, even though the overall macroeconomic picture remains relatively stable. US stock indices are returning to the record highs seen at the end of January, the technology sector continues to outperform, and investor interest in risk assets is rising again. Against this background, the key question is whether the market is approaching a point after which a sharp correction may follow, similar to what happened in 2000 and 2008.
The comparison with the dot-com bubble arises primarily due to the structure of growth. As in the late 1990s, a limited group of companies linked to new technologies is driving most of the index performance. Back then, these were internet companies, while today it is artificial intelligence, cloud solutions, and semiconductors. According to Bloomberg, the share of the largest technology companies in the S&P 500 has approached levels comparable to the peaks of the early 2000s. This creates a concentration of risk, where the stability of the entire market depends on a narrow group of companies.
However, there are also important differences. Unlike the dot-com era, today’s market leaders generate real profits and have sustainable business models. According to Goldman Sachs, the overall profitability of the largest technology companies is now significantly higher than that of internet companies in 2000. This reduces the likelihood of a complete collapse in valuations, but does not rule out a correction if investor expectations become too optimistic.
A comparison with the 2008 crisis also requires caution. At that time, the key factor was the excessive debt burden of the financial system combined with a housing market bubble. Today, the banking sector appears more resilient due to stricter regulation, and systemic risk is lower. Nevertheless, as noted by the International Monetary Fund, global debt remains at historically high levels, standing at around 330% of global GDP. This means that the economy remains highly sensitive to changes in interest rates.
Central bank policy remains the key factor in the current cycle. After an aggressive rate-hiking period in 2022-2024, markets have begun to price in the possibility of rate cuts. However, the Federal Reserve’s rhetoric still suggests a willingness to keep rates high for longer than investors expect. This divergence creates additional uncertainty. On the one hand, expectations of easing support asset prices, especially in the technology sector. On the other hand, there is a risk of overvaluation if rate cuts are delayed. Analysts at XFINE note that in such conditions the market often moves ahead of reality, betting on future liquidity that may not arrive as quickly as expected.
Another risk factor is the behaviour of retail investors. According to Financial Times, the share of retail investors in US market turnover remains elevated compared to historical levels. This increases short-term volatility and raises the likelihood of local bubbles forming in certain segments. A similar pattern was observed before previous crises, when growth was driven not only by institutional flows but also by strong retail participation.
At the same time, the current situation does not justify direct comparisons with 2000 or 2008. Rather, a mixed model is emerging, where signs of overvaluation and capital concentration coexist with the absence of critical systemic imbalances. For this reason, the base scenario considered by XFINE implies not a sharp crisis, but a gradual correction as expectations regarding interest rates and economic growth are revised.
The key question for investors is not whether a correction will occur, but its scale and triggers. If inflation proves more persistent, central banks may be forced to maintain tight policy for longer, increasing pressure on stock markets. An additional risk comes from the situation in the Middle East. If oil prices remain high, this will strengthen inflationary pressure through energy costs and may accelerate a correction.
At XFINE, it is emphasised that in such conditions the priority is not to identify the exact market peak, but to manage risks and maintain diversification. Market overheating rarely ends with a sudden reversal – it is usually a prolonged process with alternating phases of growth and correction. This pattern is likely to remain dominant in the current cycle.
