The UK's blue-chip index enjoyed another good day on Monday, closing in record fashion.
The FTSE 100 ended the day ahead 65 points at 7,947.
Fawad Razaqzada, a financial market analyst at StoneX, said: "Investor sentiment has been boosted in recent months by hopes that inflation has peaked.
"So, as we transition into the new week, once again the focus is going to be on inflation and central bank speech.
"Luckily, we have plenty of inflation data to provide us direction. CPI (consumer price index) data will come out from both the UK and US, which is likely to be the key macro event of the week."
Michael Hewson, chief market analyst at CMC Markets, also told Proactive Investors: "European markets got the new week off to a positive start, helped by further declines in natural gas prices, which have slipped to their lowest levels in almost 18 months on the European Netherlands TTF contract.
Recovered
"The FTSE 100 has recovered after slipping below 7,900 last week.
"Today's weakness in oil and gas prices has prompted some underperformance in the energy sector - however this is more than offset by resilience elsewhere, specifically in industrial and consumer staples with Weir Group, Spirax-Sarco Engineering and Smiths Group outperforming.
"We've seen a little bit of softness in housebuilders, with Persimmon at the bottom of the FTSE 100 after being reduced to 'sell' by Deutsche Bank, while Taylor Wimpey and Barratt Development were cut to 'hold' from 'buy'."
The Footsie, as the index is informally known, contains the 100 most valuable companies listed in London. It was created in 1984, when it started at 1,000 points.
The FTSE 100 has a strong international focus, but has been criticised in the past as being a "Jurassic Park" index, for its lack of cutting-edge technology companies - although that helped it avoid losses last year, when big tech valuations slumped.
During 2022, it rose almost 1% - defying the wider market slump during last year as worries over inflation and rising interest rates hit equities. But the FTSE has suffered some hefty losses over its lifetime. On Black Monday in October 1987 it fell more than 10%, losing another 12.2% the next day - its worst fall ever.
