2、 forecasting accuracy of her companys primary financial services provider, JPMorgan Chase (JPMC). Vesi had focused on the three primary currencies the companys operations revolved around , the dollar, the euro, and the yenTeknekron had relied upon JPMC for most of its currency advisory services for
3、years, and the forecasts provided by JPMC were regularly used in sales and sourcing decisions including pricingThe rise of the euro against the dollar in recent years had, however, raised the interest in the accuracy of these forecasts. US dollar/euro spot exchange rateVesi plotted the forecasts pro

Although JPMC had hit the actual spot rate dead-on in both May and November 2002, the size of the forecasting errors, and direction of movement

6、art of 2004, JPMC was getting the direction wrong. In February 2004 they had forecast the spot rate to move from the current rate of $1.27/ to $1.32/, but in fact the dollar had appreciated dramatically in the following three month period to close at $1.19/. Although Teknekron used a weighted moving

10、 an overview of that analysisOnce again, although the dollar was consistently falling against the yen, the forecasting accuracy at least by eyeballing the graphic, was not encouraging.

14、ure spot rate, 90 days out?As shown in the following table, Vesi would actually have been much better off using the JPMorgan forecasts than simply using the current spot rate. The average error for the period shown was 1.2% for JPMorgan on the Us dollar/Euro, while the spot rate would have been 2.7%

Similarly, the average error for the period shown for the Japanese yen/US dollar spot rate was 0.2% for JPMorgan, while the spot rate would have been 1.7%.JP Morgans FX Forecasting: Case Questions8Copyright 2009 Pearson Prentice Hall.

17、ered, how well do you think JPMC is doing?JPMorgan seems to be doing okay for the period shown. As noted under question 1, the forecasting error is significantly less for both exchange rates than if a simple random walk (current spot rate forecast) had been used. The period under consideration is on

As is typically the case in forecasting, the biggest errors typically arise at the turning points when the price or rate changes direction. 3.If you were Vesi, what would you conclude about the relative accuracy of JPMCs spot ra
19、te forecasts? In both cases (exchange rate pairs), JPMC is consistently underestimating the actual exchange rate change. That is what the negative mean on the forecast error indicates. Given that both exchange rates are following strong trends over the sample period, and given the inherent conservatism likely to dominate the thinking of forecasting services, the sign of the average error is understandable. And the size of the error is reasonably small and relatively accurate. JP Morgans FX Forecasting: Case Questions10Copyright 2009 Pearson Prentice Hall. All rights reserved.
