Shares in Commonwealth Bank slumped to their lowest level in almost six years after the country's biggest lender finalised a $2 billion raising of capital underwritten by UBS, of which $1.65 billion was replaced on Wednesday.
"The capital raising and increase in bad debt provisions has attracted significant attention from the brokers, with a number of downgrades coming across the wire,'' IG Markets research analyst Ben Potter said, describing the capital raising as "bungled''.
CBA's shares plunged 9.09 per cent, to $26.50.

The big miners were mixed.
Rio Tinto was down 32 cents to $40.00 and BHP Billiton gained 5 cents to $31.00.
BHP Billiton said in a letter to shareholders that it would focus on expanding existing mines rather than new developments in nations where it had not yet operated during the current economic uncertainty.
"Moody's downgraded Rio's senior unsecured debt to Baa1 from A3, saying that the downgrade captures increased financial risk linked with the firm's Alcan debt and limited progress with asset disposals,'' Mr Potter said.
Energy stocks were in deep negative territory at the close.
CommSec market analyst Savanth Sebastian said the energy sector was weaker despite the Organisation of Petroleum Exporting Countries saying it would slash its output by seven per cent - its biggest yet production cut.
He said the cut did not necessarily mean oil producing nations would comply with the directive.
