“…Bawa and Lindenberg (1977) and Ang, Chen, and Xing (2006), for example, introduce (conditional) upside and downside market betas which measure sensitivities of stock return to the market over periods of high and low market return. More recently, Lettau, Maggiori, and Weber (2014), Dobrynskaya (2014), and Atanasov and Nitschka (2014) employ akin risk measures to study conditional market risk in the cross‐section of foreign exchange rate returns and returns on assets in other classes such as equities, commodities, sovereign bonds, and index options. Analogously, Delisle, Doran, and Peterson (2011) allow for different return sensitivities to upside and downside implied systematic volatility.…”
