In the present research I investigate the impact of operating leverage on profitability and financial leverage in Korean Market. I find that for firms, with a positive profitability, operating leverage increases profitability and reduces financial leverage in good times. Hence, operating leverage is an explanatory variable of the negative correlation between financial leverage and profitability of a firm, which is inconsistent with trade-off theory. Operating leverage is assumed as the fixed-cost, and in good times it increases profitability, however in recession it may increase a bankruptcy risk and lead company to a financial distress earlier than managers predict. Using three different natural events, China’s entry into the World Trade Organization in 2001, Asian Financial Crisis in 1997 and The World Financial Crisis 2008, as exogenous shocks on capital structure, I check how managers adjust operating leverage and how these adjustments impact on profitability and financial leverage. I believe that when managers decide to increase operating leverage, they choose to lower financial leverage, to reduce firm’s risk of default. Book leverage of the post period of China’s entry to WTO strongly support prediction, that financial leverage reduced under influence of operating leverage. However, there is no significant evidence for market leverage. To find more evidence I chose Asian Financial Crisis 1997 as another exogenous shock event. The data shows significant positive relations between operating and book leverage. As Yun (2003) reports, Asian Financial Crisis influenced firms to reduce operating and financial leverage at the same time, causing positive correlation between them. On the assumption of results, I conclude that data supports prediction that there is a positive relation between operating leverage, and that profitability, and negative relation between operating and financial leverage is the explanatory variables of negative relation between profitability and financial leverage.
