The Price to Book Value (P/BV) ratio exhibits three distinct phases between 2006 and 2023, characterized by an initial period of steady growth, a window of extreme volatility, and a subsequent phase of relative stabilization.
- Valuation Expansion (2006–2014)
- During this interval, the P/BV ratio climbed steadily from 1.92 in 2006 to a peak of 5.23 in 2014. This trend was driven by a consistent increase in share price, which rose from 14.71 to 58.81, significantly outpacing the growth of the book value per share, which moved from 7.65 to 11.25. This progression indicates a period of expanding market premiums over the accounting value of the assets.
- Anomalous Valuation Distortion (2015–2017)
- A significant disruption occurred between 2015 and 2017, during which the P/BV ratio reached extreme levels, culminating in a peak of 60.35 in 2017. This surge was not the result of price appreciation, but rather a precipitous decline in the book value per share, which collapsed from 11.25 in 2014 to 0.90 in 2017. The extreme divergence between the market price and the underlying book value suggests substantial asset write-downs or fundamental structural changes to the balance sheet during this period.
- Normalization and Stabilization (2018–2023)
- Beginning in 2018, the P/BV ratio returned to historical norms, fluctuating within a range of 3.36 to 4.89. This normalization coincided with a sharp recovery in the book value per share, which jumped to 13.46 in 2018 and reached 14.52 by 2023. Despite volatility in the share price—most notably a decline to 45.62 in 2021—the ratio remained stable, suggesting a realignment of the market valuation with the recovered asset base.
