Vasta Platform shares surge 11.67% premarket as valuation metrics indicate undervaluation with P/E of 4 and PEG of 0.01.

Vasta Platform surged 11.67% in premarket trading following a valuation analysis highlighting its undervaluation. The company’s P/E ratio of 4, Price to Book Value of 0.39, and PEG ratio of 0.01—significantly lower than peers like Viant Technology—positioned it as attractively undervalued as of November 14, 2025. This analysis, emphasizing favorable metrics compared to the broader market, likely fueled investor optimism ahead of the session. While a separate report noted analyst skepticism and a "Underperform" consensus, the recent valuation shift appears to have driven the upward move, overshadowing longer-term uncertainties.
