Goldman Sachs has downgraded the ratings and price targets for several companies, including Altair Engineering and Coinbase, predicting significant revenue declines as it adopts a pessimistic market stance. The price target for Coinbase was notably reduced from $70 to $45, with expectations of a 61% revenue drop in 2022. In contrast, the firm announced a 25% increase in its own quarterly dividend to $2.50 per share, reflecting a strategy to maintain investor confidence amidst economic uncertainty.
