Peter Hargreaves has moved into the top 50 in this year's Sunday Times Rich List, following a strong year for Hargreaves Lansdown, the company he co-founded in 1981.
According to The Sunday Times Rich List 2018, Hargreaves jumped nine places to 42nd with his wealth increasing by £849m to £3.2bn as Hargreaves Lansdown, in which he has a 32.2% stake, saw its value rise £809m in a year to just over £2.9bn.
Last year, Hargreaves invested £25m in Blue Whale Capital, an asset management firm founded by ex-Artemis manager Stephen Yiu.
It was also reported over the weekend that the Bristol-based investor has entered the aerospace sector, according to The Sunday Times, by pouring £24m into the Goonhilly Earth Station, a company which provides spacecraft tracking and monitoring services.
Meanwhile, fellow Hargreaves Lansdown founder Stephen Lansdown saw his wealth rise £240m to £1.7bn in this year's list, which puts him in 76th place, up from 86th last year.
However, hedge fund manager Crispin Odey and wife Nichola Pease once again saw their wealth drop £25m to £750m, putting them in 180th= place.
The pair fell out of the Rich List's top 100 and the billionaire's list in 2016 after seeing their wealth slide by £200m to £900m. It also fell in 2017.
Odey's funds under management dropped from $11.7bn at the start of 2015 to $6bn at the end of August last year, as a result of a number of bearish bets against the UK economy in the wake of the Brexit vote in June 2016.
It was revealed last month he has built up a short position against UK government debt that is now worth 154.8% of his flagship €173m European fund.
Elsewhere, Virgin founder Sir Richard Branson witnessed his wealth fall £340m to £4.5bn, which meant he slid six places to 29th.
Earlier this month, it was announced Branson is set to become a partner in a private equity fund investing in consumer goods. The fund will invest in Europe and the US and the firm is hopeful of targeting large institutional investors such as the Public Investment Fund (PIF) in Saudi Arabia.
Other notable names from the finance sector on the list include fund manager Terry Smith, who jumped into the top 500 for the first time after his wealth rose £30m to £250m.
Co-founder and chairman of Ruffer Investments Jonathan Ruffer also saw his wealth rise £19m to £425m, putting him just outside the top 300 in 301st place.
According to the Rich List, this year's rankings see the combined fortune of the wealthiest 1,000 rise to £724bn, up 10% on last year's record of £658bn.
