Morgan Stanley has reduced its price target for Carnival Corporation's stock to $7 per share from $13, attributing the downgrade to rising concerns over the company's debt levels and declining demand. This decision establishes a new Wall Street-low for Carnival, with warnings that the shares could risk losing all their value in a worsening market. Conversely, Morgan Stanley announced an 11% dividend increase following the Federal Reserve's endorsement of major banks, contributing to a 3.2% rise in its own stock.
