Company Performance: Financial health and growth prospects drive investor confidence, directly impacting the stock price. Strong earnings, revenue growth, and positive future guidance typically lead to price increases.

Market Conditions: Broad economic trends, industry performance, and overall investor sentiment significantly influence stock valuations. Bull markets tend to lift most stocks, while bear markets have the opposite effect.

Interest Rates: Rising interest rates can make borrowing more expensive for companies, potentially slowing growth and negatively affecting stock prices. Conversely, lower rates can stimulate economic activity.

Inflation: High inflation can erode corporate profits and consumer spending, leading to decreased investor confidence and potential price declines. Central bank policies to combat inflation also play a role.

News & Events: Company-specific news (e.g., product launches, acquisitions) and major global events (e.g., geopolitical tensions, natural disasters) can trigger immediate price fluctuations due to changes in investor expectations.

Competitive Landscape: Actions by competitors, shifts in market share, and technological advancements can all impact a company's competitive position and, subsequently, its stock price.
