Shares in Aviva slid today after the UK insurer announced it would reorganise into five divisions and sell its stake in its Hong Kong business.
The measures fell short of investor expectations for a broader change in strategy.
The life and general insurer has been struggling to find direction, analysts and investors say, after replacing its chief executive earlier this year.
Analysts had speculated Aviva might announce that it would sell smaller European operations such as France or Italy to focus on the UK, or offload books of life insurance closed to new customers.
Aviva is folding Aviva Investors, its fund management arm, into a broader investments, savings and retirement division.
The other four new divisions are UK life, Europe life, Asia life, and general insurance, it said ahead of an investor day.
"What we are laying out today is a simpler strategy, simpler structure and attractive growth engines," chief executive Maurice Tulloch, who took over the top job in March, told Reuters.
Insurers and asset managers have been moving away from large, diverse operations.
Prudential split into two last month, while last year Old Mutual broke up into four parts and Standard Life sold off its insurance business following its merger with Aberdeen Asset Management.
Aviva also today set out several three-year targets, including a 12% return on equity and a £300m net cost saving by 2022.
It said it was committed to its progressive dividend policy and saw 2019 operating profit in line with management expectations, following around £300-400m in "management actions", which typically include cost cutting.
Aviva said it was in discussions about the future of its businesses in Vietnam and Indonesia, following the sale to joint venture partner Hillhouse Capital of its 40% stake in the Hong Kong business, named Blue.
CEO Tulloch declined to disclose the terms of the sale.
Tencent Holdings, China's biggest gaming and social media company, also has a 20% stake in Blue.
Aviva said this week it was keeping its Singapore operation following a review of its Asian businesses, raising speculation it could not get a satisfactory price for it.
The insurer also said it was keeping its joint venture in China.
