"The 'Stock God' Buffett's blessing causes UnitedHealth Group Incorporated (UNH.US) to surge, driving the Dow to reach a new all-time high."

The Dow Jones Industrial Average fell back on Friday after hitting a historic high, ending the day almost flat. Market sentiment has been continuously optimistic recently, and Warren Buffett's latest investment actions became the focus of the day's market momentum. According to FactSet data, the Dow rose more than 200 points in early trading, hitting an intraday historic high of 45,203.52 points, surpassing the record of 45,073.63 points set on December 4th last year. However, as investors digested economic data, the gains narrowed in the afternoon, ultimately rising only 34.86 points and closing at 44,946.12 points, with an increase of less than 0.1%, failing to achieve a record high close. In order to record the first historic high close of the year, the Dow would need to surpass 45,014.04 points. The highlight of the day came from UnitedHealth Group Incorporated (UNH.US). Benefiting from Berkshire Hathaway's disclosed holdings in the latest quarterly filing, UnitedHealth Group Incorporated's stock surged nearly 12%, marking the largest single-day increase since November 2020. According to Dow Jones market data, the stock contributed over 167 points to the Dow in early trading, becoming an important driver of the index's upward movement. It is worth noting that although UnitedHealth Group Incorporated's stock price has fallen over 40% since the beginning of the year, its weighting in the Dow component stocks has dropped from first place at the beginning of the year to ninth. However, its stock price fluctuations still have a significant impact on the overall performance of the Dow. In contrast to the Dow's performance, the other two major indexes were under pressure on Friday. The S&P 500 index fell 0.29% and the Nasdaq Composite Index fell 0.40%. This indicates a "divergence" in the three major US stock indexes in 2025, with the Dow setting an intraday high while the S&P and Nasdaq hovered in adjustment. Analysts pointed out that the Dow, as a price-weighted index unlike the market capitalization-weighted S&P 500, is more easily influenced by individual stock price fluctuations. Timothy Chubb, Chief Investment Officer at Girard, stated, "The Dow has limited components and a relatively narrow coverage, combined with its price-weighted mechanism, it cannot fully reflect the overall market value. Therefore, we don't place too much importance on it as a reference in our investments."
