霍华德·马克斯：美股处于泡沫的“早期阶段”，尽管回调的关键点尚未到来

Core Viewpoint - The current valuation of the U.S. stock market is at historical highs, particularly the ratio of total market capitalization to GDP, which raises concerns about potential market corrections [1][4][7]. Valuation Concerns - The U.S. stock market is showing signs of being in the "early stages" of a bubble, with high valuations particularly in technology stocks [3][4]. - The "Buffett Indicator," which measures total market capitalization against GDP, indicates that the U.S. stock market is "severely overvalued" at 217% [7]. - The actual valuation pressure may be underestimated due to many companies being privatized or delaying IPOs, leading to a more concerning situation than it appears [4]. Historical Context - The current market environment is reminiscent of the late 1990s, when there was significant enthusiasm for technology stocks, leading to Alan Greenspan's warning about "irrational exuberance" [5]. - Despite the warning, the market continued to rise for several years before the tech bubble eventually burst, suggesting that the current upward trend may still have room to continue [5]. Investment Strategy - Given the high valuations, the recommendation is to adopt a defensive investment strategy [7]. - Although the investment environment in the U.S. has slightly deteriorated, it remains one of the best investment destinations globally, akin to a "high-priced good car" [8]. - The focus should be on selecting more defensive assets, such as credit, within this high-priced investment landscape [8].
