The Stock to Flow (S/F) Deflection is the ratio between the current Bitcoin price and the S/F model. If deflection is ≥ 1 it means that Bitcoin is overvalued according to the S/F model, otherwise undervalued.

This is the Point-in-Time (PiT) variant of Stock-to-Flow Deflection. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
