The broader market extended its rally today, with the All Ordinaries adding 14 points to 5,115 by the close and the ASX 200 up 0.3 per cent to 5,099.
Mr Kloppers' resignation from BHP has overshadowed the company's biggest fall in half-year profits in more than a decade, with results posted today showing them down 58 per cent to $4 billion.
The results come on the back of lower commodity prices, a stronger dollar and writedowns.
Mr Kloppers' resignation comes just weeks after Rio Tinto sacked its boss.
His replacement, Andrew Mackenzie, plans to grow future profits through productivity.
BHP's dividend increased from 55 to 57 US cents a share, which was below expectations.
Shares lost 0.9 per cent to $38.65.
The slump in iron ore prices late last year cut Fortescue Metal's profits almost in half, but the company says the outlook is more positive.
First half net profit fell 40 per cent to $462 million and the interim dividend was scrapped.
Investors did not like that at all and looked past the company's fairly upbeat outlook, with shares dropping 5 per cent to $4.92.
Electrical manufacturer Breville also reported its half-year results today, with shares diving 22 per cent after profits rose 7 per cent, which was short of expectations.
Breville also raised the possibility it may lose a key distribution contract in Canada.
Breville was one of the top three performers on the ASX 200 last year.
Also releasing results today was Suncorp, which thanks to some reprieve from natural disasters, saw a 48 per cent rise in profit.
The Australian dollar climbed throughout trade today and shortly before 5:00pm (AEDT) it was at 103.6 US cents, 77.2 euro cents, 66.1 British pence and 96.6 Japanese yen.
West Texas crude closed higher at $US97 a barrel, Tapis was flat at $US123 and spot gold was down to $1,607 an ounce.
