The suspended Woodford Equity Income fund has lost 12.8 per cent since it closed its door to investors at the start of June.
The fund was suspended on June 3 following a wave of redemptions and a prolonged bout of poor performance.
The outflows ran at a rate of £9m every working day.
Data released by Link, the authorised corporate director of the fund, wrote in its latest update to investors that from June 3 to September 20 the fund lost 12.8 per cent, while the FTSE All Share Total Return sector gained 4.2 per cent.
The Link update said the ambition was to re-open the fund in early December, but for now the suspension remains in place.
The statement from Link read: "As noted in our previous letter we continue to monitor progress of the repositioning of the fund’s portfolio against the December timeline, and have decided that it remains in the interests of all investors for the suspension of dealings to continue.
"This has been agreed with the depositary and we have informed the Financial Conduct Authority accordingly."
During the period of suspension, Mr Woodford has sold hundreds of millions of pounds worth of shares as he seeks to raise capital to meet the expected waive of redemptions.
Millions has also been invested in FTSE 100 stocks. Mr Woodford intends to stick to the same investment and market outlook, but to deploy the capital into larger companies where the shares have ample liquidity. He suffered a fresh blow recently when the shres of one of his largest investments, Stobart, were suspended.
The fund has shrunk in size to £3.1bn.
