12. Conclusion Jump Contributions are not significant to beta. In other words, market systematic risks are not affected jumps in prices of individual stocks. So CAPM model will not be affected by outliers in returns as some papers claim (Martin, Simin, 2003) During periods of financial stress, Financial firms tend to have a beta above 1. On the contrary, the beta of Food&Beverage Providers remain low during financial stress. (Some even decrease) In general, financial firms have higher beta.
