A buying opportunity in a stock occurs when a short-term fluctuation allows for the security to be mispriced. Value is relative to an investor’s own criteria. An example is a one-time problem, such as a strike at a mine, which results in the shares of the firm being sold off. This selloff might offer a long-term investor the opportunity to buy shares of the mining company at a favorable value. Buying opportunities occur for various reasons, but the goal of any investor is to accumulate assets at favorable levels. If an asset is selling at below market value and an investor believed that the business would recover, this would be a great example of a buying opportunity.
