On Wednesday, Sasol’s share price lost 13% of its value, followed by another 5% on Thursday – wiping R38 billion off its market capitalisation.

The market was displeased after Sasol admitted that its embattled Lake Charles Chemicals Project in Louisiana in the US will now cost as much as $12.9bn - that’s almost $1bn more than the company expected three months ago. 

Sasol wasn't the only large company to suffer big losses. On Thursday, Massmart’s share price tanked by 14% in a single day - after warning that its earnings for the current six months will be at least 50% lower than last year.

Painful as they were, these losses do not even rank among the top 10 one-day slumps on the JSE
