AMP shares jumped 13% this week, putting the Australian wealth manager on track for its strongest weekly stock market performance in nearly four months as investors welcomed improved earnings and a new share buyback program. The rally extends a strong run for AMP, with the stock poised to record its fourth consecutive week of gains. On Friday, AMP shares were last trading 2.4% higher, bringing their advance since the beginning of 2026 to approximately 33.5%. Adding to the positive market reaction, AMP announced plans for an A$150 million ($105.41 million) share buyback. The combination of stronger first-half earnings and the A$150 million buyback helped propel AMP shares sharply higher during the week.
