有哪些指标，能帮我们判断一个品种是不是便宜呢？｜投资小知识

Core Viewpoint - Investing in indices like the CSI 300 during a bull market may lead to losses, while investing during a bear market increases the probability of future gains [2] Valuation Indicators - The most commonly used valuation indicators include four main types: 1. Price-to-Earnings Ratio (PE): This ratio is defined as market value divided by earnings, indicating how much investors are willing to pay for 1 unit of net profit. A lower PE suggests that the index is "cheaper" [3] 2. Earnings Yield: This is the inverse of the PE ratio, calculated as earnings divided by market value. A higher earnings yield indicates that the index is "cheaper" [6] 3. Price-to-Book Ratio (PB): Defined as market value divided by net assets, this ratio reflects how much investors are willing to pay for 1 unit of net assets. A lower PB suggests that the index is "cheaper" [7] 4. Dividend Yield: This is calculated by dividing the total cash dividends of all companies behind the index by the market value. A higher dividend yield often indicates that the underlying companies have lower valuations, but it should be assessed alongside the stability of dividends [9] - It is important to note that each of these valuation indicators has its own advantages and limitations, and different types of indices may require a focus on specific indicators [10]
