The maintenance of an Outperform rating suggests a positive outlook on Invesco's performance, indicating analyst confidence in the company's future. However, the reduction in the price target could reflect a reassessment of the company's valuation or expected performance, which might be due to market conditions or company-specific factors. This news is likely to have a neutral short-term impact on Invesco's stock price as the positive sentiment from the Outperform rating could be offset by the lowered price target.
