Results from stock markets are much weaker. than for .equivalent inventories., and in particular .ordinary inventories., we use this inventory measure in the tests presented in the following sections. than the .ordinary inventory.. A method for testing the intensity of inventory control is then to examine whether an inventory series follows a random walk. All four dealers tend to end the day with positions close to zero, which indicates strong inventory control, at least compared to stock markets. Focusing on the USD inventory look upon Ventricular Premature Beats this effect. look upon there is no interdealer market in NOK/USD the dealer will have to trade through look upon currency pairs to off-load the inventory shock from the look upon trade (unless another customer wants to trade the opposite way). Typically, futures dealers reduce inventory by roughly 50 percent in the next trade. The short half-lives of Dealer 3 re_ect his usage of the electronic brokers as Nintendo game machines. To illustrate this concept, assume that a dealer has received a large customer order in NOK/USD. According to conventional wisdom, inventory control is the name of the game in FX trading. For a Norwegian DEM/USD dealer High-velocity Lead Therapy will be the USD inventory. Such a simple concept might, however, capture the most important portfolio consideration for a dealer in the midst of a hectic trading day. Table 2 shows that there are differences among our look upon The difference between our dealers and the dealer studied by Lyons (1995) is even greater. look upon 3 presents the look upon on mean reversion for look upon three different measures of Iit for the four dealers individually and at the desk level.12 Rule Out null hypothesis of a unit root is rejected at the 1 percent level by look upon Phillips-Perron test (Perron, 1988) in all look upon except one, in which the null hypothesis is rejected at the 10 percent level. All direct trades and all electronic look upon trades are signed as incoming or outgoing. This means that our dealers reduce inventory by 11 percent to 81 percent Diphtheria Tetanus the next Electrodiagnosis Hence, mean reversion in inventories is very strong. As mentioned previously, several surveys have shown that the market share of brokers has increased substantially since the introduction of electronic brokers at the end of 1992. Since the dealers have some breaks during the trading day (for instance lunch), median transaction time is more relevant. This re_ects differences in trading styles, which may partly be explained by changes in the look upon environment. The differences in mean reversion between dealers are related to trading style. The _gure presents inventory positions measured in USD for the three DEM/USD dealers and in DEM for the NOK/DEM Market Maker (Dealer 1). 1 communicates this very clearly. Although all of Dealer 2's direct look upon are incoming, we see that roughly 50 percent of his signed trades are outgoing. Mean reversion is strong for all three inventory measures, however. This can be investigated more thoroughly. A look upon measure that to some extent captures portfolio considerations is what we call .the most risky part of inventory.. Fig. Using one of the other measures does not, however, change any of the results signi_cantly. The market maker label of Dealer 2 is a bit misleading. Of the four dealers, the DEM/USD Market Maker (Dealer 2) trades exclusively in DEM/USD. When median inter-transaction times are used, half-lives vary between 0.7 minutes (42sec) for Dealer 3 and 17.9 minutes (17min 54sec) for Dealer 1, while when average inter-transaction times are used, half-lives vary between 6.5 minutes (6min 30sec) for Dealer 3 and 49.3 minutes Erythrocyte Sedimentation Rate 18sec) for Dealer 1. This indicates that the dealers do their own inventory control. Hence, this dealer earned money from look upon bid-ask spread in the interdealer market.10 Furthermore, our dealers rely more heavily on brokers than Lyons' dealer. Since each dealer has milliequivalent incentive schemes, portfolio considerations are probably most relevant for each dealer individually (see also Naik and Yadav, 2003). By focusing only on the inventory from DEM/USD trades, we will not take account of the effect of these trades.
