Theoretically and empirically, debt and leases have been shown to be both substitutes and complements. To explore the relation, we divide our sample into two subsets: those that exhibit a complementary relation (43% increase debt after increasing leases), and those that exhibit a substitutionary relation (57% decrease debt after increasing leases). For complement firms, we find a significant negative relation between leasing and the firm's size, marginal tax rate, and z-score, consistent with “complementary” theories. For substitute firms, we find a positive and significant relation between leasing, the marginal tax rate and changes in cash. We also find a significant positive stock market reaction to the announcement of the SLB, which is stronger for the complement subset of firms.

A broad stream of research shows that information flows into underlying stock prices through the options market. For instance, prior research shows that both the Put–Call Ratio (P/C) and the Option-to-Stock Volume Ratio (O/S) predict negative future stock returns. In this paper, we compare the level of information contained in these two commonly used option volume ratios. First, we find that P/C ratios contain more predictability about future stock returns at the daily level than O/S ratios. Second, in contrast to our first set of results, O/S ratios contain more predictability about future returns at the weekly and monthly levels than P/C ratios. In fact, our tests show that while P/C ratios contain predictability about future daily returns and, to some extent, future weekly returns, the return predictability in P/C ratios is fleeting. O/S ratios, on the other hand, significantly predict negative returns at all levels: daily, weekly, and monthly. While Pan and Poteshman (2006) show that signed P/C ratios, which require proprietary data, have predictive power, we find that unsigned P/C ratios, which do not require proprietary data, also have predictive power.
