Swartzberg’s Discovery stake plunges $40 million

Swartzberg, who shaped Discovery Health’s marketing, distribution, and operations, holds a 3.92-percent stake in the Sandton-based company—equal to 25,954,540 shares. According to data tracked by Billionaires.Africa, the value of his stake has slipped by R776.82 million ($40.11 million) in just over a month, as concerns grow over global economic tensions and investors pull back.

The recent decline follows a short-lived rebound between Feb. 3 and 17, when Discovery shares climbed on the back of stronger-than-expected interim results. During that stretch, Swartzberg’s stake gained around $20 million in value, rising from R4.63 billion ($251.64 million) to R4.99 billion ($271.58 million), as investors briefly regained confidence in South African financial stocks.

Stock slides, market cap dips below $6.5 billion

Founded in 1992 as a medical insurer, Discovery Limited has grown into one of South Africa’s biggest names in financial services. Today, the company offers everything from long- and short-term insurance to asset management, investments, and employee benefits.

But despite its strong reputation, Discovery has had a tough few weeks on the JSE. Over the past 40 days, its shares have slipped by more than 14 percent, pushing its market value below $6.5 billion. The stock dropped from R$10.94 ($9.70) on February 26 to R181.89 ($9.39) at the time of writing.

That decline has taken a toll on investors — including co-founder Barry Swartzberg. The value of his stake has dropped from R5.5 billion ($283.84 million) to R4.72 billion ($243.74 million), wiping out, R776.82 million ($40.11 million). Even so, Swartzberg remains one of the wealthiest investors on the JSE and a key figure in South African business circles.

Your money and your life

Since the start of 2025, Discovery shares are down 6.61 percent. For anyone who put $100,000 into the stock at the beginning of the year, that investment would now be worth around $93,390 — a loss of $6,610. While the drop stings, Discovery is still one of the most valuable companies on the JSE, and many long-term investors remain confident in its future.
