The valuation metrics exhibit significant volatility, characterized by an initial period of extreme earnings-based multiples followed by a phase of compression and a subsequent sharp increase in most ratios toward the end of the observed period. There is a divergent trend between asset-based valuation and earnings-based valuation.

Price to Earnings (P/E) and Price to Operating Profit (P/OP)

Both ratios began at extreme peaks in January 2023, with P/E at 1,656.49 and P/OP at 2,481.12. A period of rapid compression followed, with P/E reaching a low of 37.18 by January 2024 and P/OP declining to 87.42 by January 2026. However, a sharp reversal is observed in the final quarters, with P/E spiking to 901.90 and P/OP rising to 398.40 by July 2026, suggesting a significant decoupling of share price from bottom-line profitability during that interval.

Price to Sales (P/S)

The P/S ratio remained relatively stable between October 2021 and October 2025, fluctuating within a range of 8.70 to 15.74. A distinct upward trend emerged in 2026, where the ratio accelerated to 21.55 in January and peaked at 24.12 by July 2026. This indicates a substantial increase in market valuation relative to revenue generation in the final stages of the period.

Price to Book Value (P/BV)

Unlike the earnings and sales multiples, the P/BV ratio demonstrates a consistent and sustained downward trajectory. After peaking at 399.29 in January 2022, the ratio declined steadily, reaching 10.07 by July 2026. This persistent decrease suggests a significant expansion of the book value relative to the market price over the duration of the analysis.

Overall, the data indicates a transition from a period of extreme speculation or low profitability to a more normalized valuation phase, which is subsequently interrupted by a sharp increase in valuation multiples across P/E, P/OP, and P/S in 2026. The steady decline in P/BV serves as the only consistent stabilizing trend across the entire timeframe.

The financial data illustrates a transition from negative earnings to profitability, followed by a period of significant valuation volatility characterized by a divergence between share price and earnings per share.

Profitability Transition and Initial P/E Compression

From October 2021 through October 2022, the company operated with negative earnings per share, during which the price-to-earnings (P/E) ratio was not applicable. Profitability was first established in January 2023 with an earnings per share of 0.06. This initial transition resulted in an extreme P/E ratio of 1,656.49, which rapidly compressed to 127.17 by October 2023 as earnings grew and the valuation normalized.

Valuation Stabilization Phase

A period of relative valuation stability was observed between January 2024 and October 2024. During this window, the P/E ratio reached its lowest levels, fluctuating between 37.18 and 47.73. This stabilization was driven by a significant increase in earnings per share, which peaked at 4.17 in October 2024, keeping pace with a rising share price that climbed from 130.99 to 198.85.

Earnings Decline and Valuation Expansion

Beginning in January 2025, a marked divergence emerged between market valuation and fundamental earnings. While the share price continued a general upward trajectory, eventually reaching 338.49 in July 2026, earnings per share entered a consistent decline, dropping from 1.89 in January 2025 to 0.38 by July 2026. This combination of declining earnings and an increasing share price led to a sharp expansion of the P/E ratio, which rose from 96.98 in January 2026 to 901.90 by July 2026, indicating a significant increase in the valuation multiple relative to actual earnings.

The financial trajectory is characterized by a transition from operational losses to sustained profitability, accompanied by a substantial increase in share price and significant fluctuations in the valuation multiple.

Profitability Transition and Growth

An upward trend in operational performance is observed from October 2021 through July 2025. Operating profit per share improved from a loss of 0.58 USD to a peak of 1.86 USD. The shift to positive operating profit occurred in January 2023, initiating a period of consistent growth that lasted until the third quarter of 2025.

P/OP Ratio Compression

Upon the onset of profitability in January 2023, the Price to Operating Profit (P/OP) ratio was initially extreme at 2,481.12, a result of the very low initial profit base. Between January 2023 and January 2026, a sustained compression of this ratio occurred, with the value declining to a low of 87.42. This downward trend indicates that operating profit grew at a faster rate than the share price during this window, leading to a more grounded valuation.

Recent Valuation Divergence

A marked divergence between market valuation and operational performance emerged in the first half of 2026. During this period, the share price rose sharply from 152.35 USD in January to 338.49 USD by July. Simultaneously, operating profit per share declined from 1.74 USD to 0.85 USD. This inverse relationship caused the P/OP ratio to expand rapidly, rising from 87.42 to 398.40, reflecting a significant increase in the premium attributed to the stock despite declining quarterly operating profits.

The Price-to-Sales (P/S) ratio exhibits significant volatility and a strong overall upward trajectory over the analyzed period, expanding from 11.48 in October 2021 to 24.12 by July 2026. While sales per share grew steadily throughout the timeframe, the fluctuations in the P/S ratio were primarily driven by aggressive movements in the share price.

P/S Ratio Trend Phases

An initial contraction phase is observed between October 2021 and October 2022, during which the P/S ratio declined from 11.48 to a period low of 8.70. This was followed by a sustained expansion phase from January 2023 through October 2024, where the ratio climbed to 15.74. A period of relative stabilization occurred throughout 2025, followed by a sharp escalation in the first half of 2026, culminating in a peak of 24.12.

Sales per Share Performance

Revenue growth per share remained consistently positive for the majority of the period, rising from 7.70 in October 2021 to 14.03 in July 2026. This organic growth provided a fundamental floor for the valuation; however, the growth rate of sales per share was significantly outpaced by the growth rate of the share price in the latter stages of the analysis.

Valuation Divergence

A notable divergence between revenue growth and market valuation occurred in 2026. Between January 2026 and July 2026, the share price increased from 152.35 to 338.49, while sales per share grew more modestly from 12.12 to 14.03. This disparity resulted in the P/S ratio nearly doubling from 12.57 to 24.12 within a six-month window, indicating a substantial increase in the market premium assigned to each dollar of revenue.

The Price to Book Value (P/BV) ratio exhibits a pronounced long-term downward trend, transitioning from extreme volatility and high valuations to a more compressed and stable range. While the share price generally appreciated over the observed period, the growth in book value per share outpaced share price appreciation, leading to a significant reduction in the P/BV multiple.

Initial Valuation Volatility

Between October 2021 and October 2022, the P/BV ratio experienced severe fluctuations, peaking at 399.29 in January 2022. These extreme values were driven by a very low book value per share, which dipped to 0.20 USD during the same period, creating a disproportionate ratio relative to the market price.

Systematic Ratio Compression

A consistent decline in the P/BV ratio is observed from January 2023 onward. The ratio fell from 77.94 in January 2023 to 19.43 by January 2024, eventually reaching a period low of 8.26 in April 2026. This trend indicates a shift toward a valuation more closely aligned with the company's tangible net assets.

Book Value Per Share Expansion

The compression of the P/BV ratio is primarily attributed to the substantial growth in Book Value per Share (BVPS). BVPS increased from 0.88 USD in October 2021 to 33.61 USD by July 2026. A notable acceleration in equity growth occurred between January 2026 and April 2026, where BVPS rose from 11.51 USD to 33.95 USD, contributing to the sharpest drop in the P/BV ratio.

Price and Value Correlation

Despite the share price increasing from 88.39 USD in October 2021 to 338.49 USD in July 2026, the P/BV ratio decreased because the underlying book value grew at a significantly higher percentage rate than the market price. This suggests an improvement in the company's balance sheet strength relative to its market capitalization.
