Bottom-hunting refers to the operation strategy of measuring the stock price to the lowest point by some valuation index, especially when it falls sharply in a short period of time, expecting the stock price to rebound soon. But what kind of price is the "cheapest" is actually difficult to judge. Buying the cheapest stock is an investment opportunity that all investors yearn for, and it is also a profit model that value investors believe in. However, what kind of price is the "cheapest" price, or "bottom", there is no clear standard. Hunting the bottom is often a description of what has happened at the lowest point, but it is difficult to judge what kind of point is the bottom in the future. In addition, the rapid decline of some stock prices is not due to underestimation, but often due to problems in the company's fundamentals. If you buy at this time, not only will the stock price not rebound soon, on the contrary, it may fall further before the fundamentals are clear. Peter Lynch, an investment guru, famously said, "Don't copy the bottom". This means that if investors are convinced that the stock price has fallen below a reasonable valuation level without major problems in the company's fundamentals, they can consider buying without trying to predict the bottom of the stock price.
