Can diversify firm specific risk at all?

Yes, firms can diversify firm-specific risk, which is the risk associated with individual companies that can be mitigated through diversification. By investing in a variety of assets across different industries and sectors, investors can reduce the impact of any single company's poor performance on their overall portfolio. However, firm-specific risk cannot be eliminated entirely; it can only be reduced through effective diversification strategies. Ultimately, systematic risk, which affects the entire market, remains unavoidable and cannot be diversified away.
