What happened
The FTSE 100 jumped 1.76 percent to close at 10663, one of its strongest days of the year. Optimism that interest rates have peaked, along with firmer commodity prices, pushed London blue chips sharply higher.
Why it matters
The FTSE 100 is home to many of the largest UK banks, miners and energy firms, so a strong session signals confidence in the wider UK economy. It also lifts the value of the pension and dividend funds that track the index.
Explained simply
Picture the FTSE 100 as a basket holding one hundred of the biggest UK listed companies. When the basket gets heavier, it usually means investors are willing to pay more for the future earnings of those firms. Today the basket filled up quickly as traders bet that cheaper money is on the way.
What it means for you
If you hold a UK equity income ISA or a workplace pension, a rising FTSE feeds directly into your balance and your dividends. It is worth remembering that big single day gains can reverse, so steady regular investing usually beats chasing the rally.
