140 7 A Kalman filter based conditional multifactor pric<strong>in</strong>g model<br />
Table 7.5: Risk factor cross-correlations.<br />
This table reports the estimated contemporaneous correlations between the risk factors for<br />
different time periods. Panel A covers to full sample from 8 January 1992 to 2 February 2005.<br />
The rema<strong>in</strong><strong>in</strong>g panels refer to four subperiods: the first break takes place at 15 February 1995<br />
represent<strong>in</strong>g the end <strong>of</strong> the formation period and the beg<strong>in</strong>n<strong>in</strong>g <strong>of</strong> the out-<strong>of</strong>-sample period<br />
(520 obsrevations). The out-<strong>of</strong>-sample period itself is broken <strong>in</strong>to three subsamples accord<strong>in</strong>g<br />
to different market regimes: Panel C reaches to end <strong>of</strong> the TMT bubble, Panel D covers the<br />
subsequent bear market, and Panel E refers to the market recovery that began thereafter.<br />
