We derive testable implications of Kyle and Obizhaeva's (2016) notion of "bet invariance'' for the cross-section of trade-time volatilities. We jointly develop theoretical foundations of "no speculative arbitrage'' whose implications incorporate those of bet invariance. Our proposed test...

The profit to a standard short-term return reversal strategy can be decomposed analytically into four components related to (1) across-industry return momentum; (2) within-industry variation in expected returns; (3) underreaction to within-industry cash flow news; (4) and a residual. Only the...
