The downgrade to Equal-Weight suggests a neutral outlook on AXP's stock performance in the short term, indicating that Barclays believes the stock might not outperform the market as previously expected. However, the slight increase in the price target to $221 implies a modestly positive view on the company's valuation. This mixed signal could lead to a neutral impact on the stock price in the short term as investors digest both the downgrade and the increased price target.
