A **bullish run** refers to a period in financial markets when the price of an asset, such as stocks, commodities, or cryptocurrencies, is rising or expected to rise. This is typically driven by positive investor sentiment, strong market demand, or favorable economic conditions. During a bullish run, traders and investors anticipate further growth, leading to increased buying activity.

### Characteristics of a Bullish Run:

1. **Rising Prices**: The most obvious feature of a bullish run is the consistent upward movement in prices over a period of time.

2. **Increased Trading Volume**: A bullish run is often accompanied by higher trading volumes, as more investors participate in the market.

3. **Investor Optimism**: Positive news, earnings reports, or economic data can fuel the optimism driving a bullish market.

4. **Market Sentiment**: A widespread belief that the market or a specific asset will continue to rise often pushes more investors to buy in.

A bullish market can last for weeks, months, or even years, depending on the conditions driving it, but it often comes to an end when prices become too high and the market begins to correct itself.
