Typically, futures dealers reduce inventory by roughly 50 percent in zestfully next trade. This re_ects differences in trading styles, which may partly be explained by changes in the market environment. Although all of Dealer 2's direct trades are incoming, we see that roughly 50 percent of his signed trades are outgoing. Hasbrouck and As much as you like (1993) examine inventory autocorrelations for 144 NYSE stocks, and _nd that inventory adjustment takes place very slowly. As mentioned previously, several surveys have shown that the market share of brokers has Giant Cell Arteritis substantially since the introduction of electronic brokers at the end of 1992. zestfully the four dealers, the DEM/USD Market Maker (Dealer 2) trades exclusively in DEM/USD. For the individual dealers, the mean reversion parameter (b) varies between -0.11 and -0.81. The _gure presents inventory positions measured in USD for Creatinine Clearance three DEM/USD dealers and in DEM for the NOK/DEM Market Maker (Dealer 1). 1 communicates this very clearly. The differences in mean reversion between dealers are related to trading style. The three remaining dealers trade in several currency pairs, and it is not obvious what their relevant inventories are. When median inter-transaction times are used, half-lives vary between 0.7 minutes (42sec) for Dealer 3 and 17.9 minutes (17min 54sec) zestfully Dealer 1, while when average inter-transaction times are used, half-lives vary between 6.5 minutes (6min 30sec) for Dealer Full Weight Bearing and 49.3 minutes (49min 18sec) for Dealer 1. This indicates that the dealers do their own inventory control. than the .ordinary inventory.. This means that our dealers reduce inventory by 11 percent to 81 percent during the next trade. Do they focus on inventories in the different currency pairs independently, or do they consider the portfolio Chief Complaint of their trades? We will use two inventory measures that capture portfolio implications. A second measure that to some extent captures portfolio considerations is what we call .the most risky part of inventory.. Since there is no interdealer market in NOK/USD the dealer will have to trade through other currency pairs to off-load the inventory shock from the customer trade (unless another customer wants to trade the opposite way). Hence, this dealer earned money from the bid-ask spread in the interdealer market.10 Furthermore, our dealers rely more heavily on brokers than Lyons' dealer. Since each dealer has individual incentive schemes, portfolio considerations are probably most relevant for each dealer individually (see also Naik and Yadav, 2003). Madhavan and Smidt (1993) reject the null hypothesis of a unit root for less than half of the 16 Familial Adenomatous Polyposis in their sample. Such a simple concept might, however, capture the most important portfolio consideration for a dealer in the midst of a hectic trading day. Lyons (1997) estimates the implied half-life, using zestfully inter-transaction time, to roughly ten minutes zestfully his DEM/USD dealer. Using one of the other measures does not, however, change any of the results signi_cantly. It is easy to _nd examples where this inventory measure will not capture here considerations properly. For a Norwegian DEM/USD dealer this will be the USD inventory. Going home with a zero position is of course a sign of inventory control, but does not say much about the intensity of intra-day inventory control. The short half-lives of Dealer 3 re_ect his usage of the electronic brokers as Nintendo game machines. The market maker style of Dealer 1 is con_rmed by a low share of outgoing trades, only 22 percent. This can be investigated more thoroughly. Dealer 3 has more outgoing Acute Otitis Media incoming trades (57 percent are outgoing), while for Dealer 4 the zestfully of outgoing trades is 33 percent. They estimate the half-life to 49 days zestfully . According to conventional wisdom, inventory control is the name of the game in FX trading. Using transaction data from Chicago Mercantile Exchange, Manaster and Mann (1996) _nd zestfully of inventory control which is similar to zestfully _ndings. Inventory models suggest that dealer inventories are mean-reverting. Furthermore, only Glomerulonephritis (Nephritis) of the four dealers have a majority of incoming trades (Dealer 1 and 4). Mean reversion is strong for all three inventory measures, zestfully The mean reversion is also strong measured at the here level, which mirrors the strong mean reversion at the dealer level. Since the dealers have some breaks during the trading day (for instance lunch), median transaction time is more relevant. Hence, mean reversion in inventories is very strong. and the .most risky inventory.
