FedEx Is Slightly Overvalued

| About: FedEx Corporation (FDX)

Here we present a tentative model for the evolution of FedEx (NYSE:FDX) stock price. The best CPIs are selected from a set of 92 CPIs with estimates available from 2000 (one may extend this set). The best fit (in the LSQ sense) consumer price indices are that of food and beverages (F - CUUS0000SAF) and the index of communication (CO - CUUR0000SAE2). The latter index is directly related to FedEx and the former one seems to be mainly independent and evolving according to own forces. The defining time lags are as follows: the food index leads the share price by 3 months and the CO index leads by 5 months:

FDX(t) = -4.87F(t-3) - 5.09CO(t-5) + 26.50(t-1990) + 1039.05, February 2012

where FDX(t) is the FDX share price in U.S. dollars, t is calendar time. Figure 1 displays the evolution of both defining indices since 2002. Figure 2 depicts the high and low monthly prices for a share together with the predicted and measured monthly closing prices (adjusted for dividends and splits). The predicted prices are mainly within the bounds of the share price uncertainty and lead by 3 months. Since the measured price volatility is much higher than the predicted one there are some large deviations from the predicted level. In any case, such fluctuations have always ended on the predicted curve. One can use this observation for a qualitative forecast of the future price movements.

It should be noted that here we present a tentative model which is fresh and needs to be validated by new data (new CPI estimates will be published tomorrow).

The model residual error is shown in Figure 3 with the standard deviation between July 2003 and January 2012 of $6.33. It is not excluded that the share will have a negative correction in April/May.
