This chapter discusses contracts for differences (CFDs), which allow investors to take long or short positions on underlying assets like stocks without owning the actual assets. CFDs offer leverage, low costs, and global trading opportunities. The chapter outlines CFD trading mechanisms involving margin, marked-to-market pricing, and margin calls. It also discusses order types, financing costs, and strategies like dividend capture and pairs trading. Risks include liquidation if margin requirements are not met and potential losses greater than the initial investment due to leverage.
