A bull run refers to a period in financial markets characterized by rising asset prices, typically in stocks or cryptocurrencies. During a bull run, investor confidence is high, leading to increased buying activity and optimism about future performance. This trend can be driven by various factors, including strong economic indicators, positive news, or market sentiment. Bull runs can last for an extended period, often resulting in significant gains for investors. However, it is essential to recognize that bull runs can eventually end, leading to corrections or bear markets where prices decline. Understanding market dynamics is crucial for investors during these phases.
