The primary factor influencing a firm's beta value is the volatility of the company's earnings. Beta measures a stock's relative volatility in relation to the overall market. A higher beta indicates that the stock is more volatile than the market, meaning it tends to experience larger price swings in either direction in response to market movements.

Volatility in a company's earnings can reflect underlying business risk, such as fluctuations in revenue and expenses, economic conditions, and operational stability. If a company's earnings are highly volatile, its stock price is likely to be more susceptible to changes, resulting in a higher beta. Conversely, stable earnings usually indicate lower risk and a lower beta.

Market competition, marketing strategies, and customer satisfaction, while important aspects of a business's overall performance, do not directly impact beta. These factors may affect a company's profitability and growth potential, but they are not the primary determinants of how the stock reacts to market-wide changes, which is what beta specifically measures.
