Another day, another all time high. As the week closed, the FTSE 100 index hit 8,433 — the highest level it has ever reached — and this is turning into a regular occurrence. The FTSE has now hit 11 all-time-highs over the last month, and it is close to equalling the record set way back in 1984 of 12 all-time-highs within a single four-week period.
