There are a number of key drivers that affect BMW's stock price. These drivers include the company's overall performance, economic trends, global events, and investor sentiment.

BMW's performance is a major factor influencing its stock price. If the company reports strong sales figures, increases in profits and positive news about their products or services, investors will see BMW as a strong investment opportunity and the stock price may rise. Likewise, if BMW reports weak sales or lower-than-expected profits, investor confidence may be eroded and the stock price could fall.

Economic trends can also greatly influence BMW's stock price. If there is an overall improvement in the economy, investors may perceive BMW as a safer investment and the stock price could increase. Conversely, if there is an economic downturn or recession, investors may become more risk-averse and look to sell their BMW stocks, driving the price down.

The Quandt family have a long history with BMW, having been shareholders since the company's founding in 1916. While the public now owns half of the company through its shares, Stefan and Susanne Quandt continue to be major stakeholders in the business.

As of 2019, Stefan holds 29% of BMW stock while his sister, Susanne Klatten, holds 21%. Both have been instrumental in the success of BMW and continue to influence the company's direction through their ownership.

Yes, BMW shares do pay dividends. According to financial data from the last 12 months, BMW has a dividend yield of 8.50%, which is higher than many other stocks in the automotive sector. Furthermore, its price-to-earnings ratio is 3.66, which means that investors can expect to receive a return on their investment for every dollar they put in. This makes BMW an attractive option for investors looking to add some income-generating stocks to their portfolios.
