Spero Therapeutics Inc is not a strong buy at this moment. The current price is $1.20, and the RSI indicates a bearish trend at 38.53, suggesting the stock is oversold. While the company has secured a significant licensing deal worth up to $1.1 billion, its recent earnings report showed zero revenue for Q2 2026 and a net loss of $9.6 million, which raises concerns about its financial stability. The stock has experienced a year-to-date change of -48.94%, indicating substantial declines, and the forward P/E ratio is currently at 0, reflecting uncertainty in future earnings. The main risk is the lack of revenue generation, as evidenced by the zero revenue reported for Q2 2026.
