Hargreaves Lansdown's head of research Mark Dampier has sold a portion of his stake in the platform giant for more than £620,000.
Dampier, one of the most widely-recognised figures in the industry, sold a total of 53,000 shares in his wife's name at a price of £11.72 per share on 24 October, according to a stock exchange filing.
The sale has netted him £621,160, following a huge spike in the price of the shares.
Hargreaves has been widely identified as one of the winners of the post-RDR world, particularly given the 'advice gap' emerging as advisers move to cater for higher net worth clients.
Hargreaves' profits - and AUM - have soared in recent years, with its share price jumping to record highs as a result.
In the last five years the share price has jumped some 676%, from 150p to a peak of £11.84.
Dampier (pictured) still holds a total of 799,262 shares, equivalent to 0.17% of the company's ordinary share capital and worth over £9m at the current price of £11.65 apiece.
