The author argues Alphabet's current TTM P/E of 16.8 is roughly 38% below its 10-year average of 27.2, implying mean-reversion upside. The mechanism is relative valuation: GOOGL trades cheaper than Meta, Microsoft, Apple, Amazon and Netflix on P/E, suggesting a discount that could close. No explicit catalyst or time horizon is given, and the main risk is that the low multiple reflects structural concerns rather than mispricing.
