The DATA page shows the 10 economic factors
which combine to create the index, their base values and their latest
values. These are updated weekly. When sufficient data has been
gathered, the movements will be charted.
Four of the factors change constantly - oil
price, FTSE100, £/$ and £/€ - and their values are recorded at each
Friday's close. The House Price Index, Retail Sales, Base Rate and
CPI (inflation) are updated monthly. Apart from Base Rate which
takes effect immediately, the others are lagged. Thus the values
available in Week 4 for House Prices relate to November 08; for
Retail Sales and CPI to December 08.
Unemployment and vacancy figures published 21/1/2009 relate to
September-November 2008.
All factors are given equal weighting. Some
organisations will need their own COBRA coefficient with different
weightings and additional components to emphasise the factors that
particularly affect them.
