The mixed analyst ratings, with some lowering and others maintaining or raising their price targets, indicate uncertainty about Teradata's future performance. The decrease in the average 12-month price target suggests a recalibration of expectations, possibly due to the financial challenges highlighted, such as lower than average revenue growth, profitability issues, and a high debt-to-equity ratio. These factors contribute to the potential for short-term volatility in Teradata's stock price, as investors digest the varied analyst perspectives and consider the company's financial health.
