Svmuu News: Legendary investor Howard Marks said in a podcast that the current market is in a boom, but it is impossible to determine whether it is irrational. Taking SpaceX’s upcoming IPO at a valuation of nearly $2 trillion as an example, it is impossible to calculate a reasonable price for such an IPO. Howard Marks noted that those who play it safe rarely achieve great things. Investing in tech giants carries the risk of making huge mistakes but also the potential for spectacular returns. Those who sit on the sidelines out of fear of risk may miss out on the greatest investment opportunities in history, while investors in traditional industries will be unable to capitalize on these epoch-making windfalls. The current S&P 500 price-to-earnings ratio is approximately 23 times, higher than the 80-year average of 16 times but lower than the 32 times seen during the 2000 dot-com bubble. When it comes to AI investing, investing in hyperscale tech companies is a low-risk approach; investing in vertical AI firms such as Anthropic and OpenAI carries higher risk but offers a higher survival rate; and investing in early-stage startups is akin to buying a lottery ticket.
