The stealth trading hypothesis (Barclay and Warner, 1993) asserts that informed traders break up their orders to conceal their trading interests, predicting that cumulative price changes are associated with orders in small or medium size categories. We revisit this hypothesis by using data from Tokyo Stock Exchange. Our results show that the price contribution of small-sized trades is, on average, significantly larger than those of medium or large-sized ones, in line with those by O’Hara, Yao, and Ye (2014). Unlike previous studies, however, we also find that the price contribution of small-sized trades depends crucially on the level of liquidity provision; specifically, it becomes small and eventually negative as liquidity is increasing. For liquid stocks, price discovery seems to occur with large orders. These results suggest that strategic decisions on order size can be considerably simplified as a result of "liquidity begetting liquidity."
