Bull vs. Bear: Why Markets Have Moods
'Bull' and 'bear' aren't just BullYeah's branding - they describe the two basic moods of the entire market.
A bull market is a sustained stretch of rising prices and general optimism - investors expect things to keep improving, so they keep buying, which (for a while) becomes self-reinforcing.
A bear market is the opposite: a sustained decline, usually defined as a 20%+ drop from a recent high, alongside pessimism and reduced buying appetite.
Underneath both is volatility - how much and how fast prices swing. A highly volatile stock can make or lose a lot of money quickly in either direction. Volatility isn't inherently bad; it's just a dial that amplifies whatever is already happening.
High-beta, high-volatility names like NVDA can move several percent in a single session in either direction - useful to see live so 'volatility' stops being an abstract word and becomes a number you can actually watch change.
