The term "oversold" is commonly used in financial markets to describe a situation where there has been an excessive decline in the price of an asset or security. This can occur when investors become overly pessimistic about the future prospects of a company, causing its stock price to drop significantly.
In technical analysis, oversold is used to refer to a condition where the relative strength index (RSI) falls below 30, indicating that the security has fallen too far in relation to recent trading activity and may be due for a bounce back up. This can provide a signal to investors or traders to consider buying the asset as it appears to be undervalued.
Overall, oversold is used to describe a situation where an asset or security has fallen too far in value relative to its fundamentals and may present a buying opportunity for those who believe that the market has overreacted.
