Institutional investors slice and dice large orders to minimize price impact. They use VWAP algorithms that trade at constant intensity for the duration of the order. Empirically, this (constant) intensity is higher for shorter orders. Observing intensity therefore makes duration predictable. This is puzzling, because investors say they prefer to trade under the radar. We rationalize the empirical findings by showing how, in theory, order predictability can benefit large orders. We further find that the presence of a large order benefits market makers unambiguously, but benefits other (small) investors only if the order trades at high enough intensity.
