As the S&P 500 soars nearly 25% from its October lows, driven primarily by a few stocks, concerns are emerging about a possible stock bubble.
Nvidia (NVDA), a popular AI pick, is leading the trend with a rise of more than 80% since the start of the year, driving both the S&P 500 and Nasdaq to record highs.
Market concentration reaches an all-time high: the ten largest US stocks represent 33% of the S&P 500’s market capitalization and 25% of its profits, according to data from Goldman Sachs.
However, some top Wall Street analysts maintain that fears of a bubble are unfounded. Drew Petit, head of U.S. equity strategy at Citi, calls it a “sales gimmick,” suggesting the market is healthier than perceived.
Tech giants such as Nvidia, Meta (META), Microsoft (MSFT), and Amazon (AMZN) have delivered strong quarterly results, reinforcing bullish sentiments. Analyst Dan Ives compares the current market scenario with that of 1995 and highlights substantial profit margins and profitability.
Chris Danely, head of U.S. semiconductor research at Citi, shares this optimism and sees no end in sight to the technology’s upward trajectory.
Underlying trends also paint a positive picture as market breadth slowly improves. Charles Schwab’s Liz Ann Sonders sees a subtle widening in the market, indicating bullish sentiment beneath the surface.
Goldman Sachs analysis over the past century suggests that periods of heightened concentration often precede market rallies. Analyst Ben Snider emphasizes the likelihood of laggards catching up rather than current leaders changing course.
