Overture, from Duncan Coker
It is good to see the market getting back to its musical roots. On Monday the market starts with an old-fashion musical overture playing a small part of each song melody giving a preview of what is to come later in the play. Then daily, one song is heard expanding on a theme. On Friday there is a Finale where the dominant songs complete the musical often with some fanfare at one extreme or the other.
Some evidence is in the fact that since 2006 Friday has the highest variance. Alas, the minima and maxima seems evenly distributed among days of week, but still believe there is a musical symmetry.
