## Key takeaways

- Hoa Phat Group P/E touched a low of 6.0 times at peak steel earnings in 2021 before net income dropped sharply in 2022.
- In 2024, Hoa Phat Group recovered net profit to VND 12,020 billion, climbing 77.0% from VND 6,800 billion in 2023.
- Construction-in-progress on Dung Quat 2 reached VND 60,108 billion as of 31/12/2024, adding future depreciation pressure upon commissioning.
- Under VNX Decision 22/QD-HDTV, listing regulations require comprehensive disclosures regarding capital assets and inventory provisions.

After mastering core principles regarding earnings per share and return on equity in the previous [lesson on EPS, ROE and earnings quality](/en/blog/eps-roe-earnings-quality), financial analysts compare profitability metrics against prevailing market prices. The two most common relative valuation multiples are price-to-earnings and price-to-book ratios. While computationally straightforward, these measures frequently set dangerous valuation traps when applied mechanically to cyclical commodity producers or firms carrying impaired assets. In this second installment of Ginity's [fundamental analysis curriculum](/en/learn/fundamental-analysis), we deconstruct the mechanisms where these multiples misstate intrinsic enterprise value.

## Fundamental Mechanics of P/E and P/B Valuation Multiples

The [P/E](/en/glossary/pe) (Price-to-Earnings) multiple assesses how much currency investors commit for each unit of after-tax corporate income. Conceptually, this metric illustrates the payback horizon assuming steady corporate earnings into the future. P/E serves as a static metric, comparing current market capitalization against trailing twelve months net earnings (Trailing P/E) or consensus forecasts for the subsequent fiscal year (Forward P/E).

Alongside P/E, the [P/B](/en/glossary/pb) (Price-to-Book) ratio compares market capitalization against book value of equity, representing net assets reported on the [balance sheet](/en/glossary/balance-sheet). Book value serves as a valuation anchor for capital-intensive sectors like banking, steel production, and commercial real estate. Under traditional accounting heuristics, a low price-to-book ratio frequently leads observers to assume liquidation downside protection.

Nonetheless, accounting equity and net profits depend heavily on statutory standards and cyclical dynamics. An unusually low P/E multiple often signals that corporate profitability reached its cyclical summit and faces contraction. Conversely, a depressed P/B ratio may conceal unviable work-in-progress or under-reserved non-performing loans.

## The Cyclical P/E Trap and Asset P/B Dynamics at Hoa Phat Group During 2021-2024

The quintessential case study of cyclical multiple distortions on the Vietnamese equity market is Hoa Phat Group (ticker HPG on HOSE). According to audited financial statements for fiscal 2021, the corporation achieved net revenue of VND 149,680 billion and record net profit after tax of VND 34,521 billion driven by surging global steel prices. At the conclusion of 2021, Hoa Phat Group trailing P/E touched a low of 6.0 times, leading retail market participants to assume shares were cheap. See the full text at [Hoa Phat Group](https://www.hoaphat.com.vn/tin-tuc/hoa-phat-lai-sau-thue-12-020-ty-dong-nam-2024.html).

However, according to audited reports for fiscal 2022, as steel sales prices moderated and input coking coal costs escalated, full-year net profit dropped 75.5% to VND 8,444 billion. The enterprise logged consecutive net operating losses during Q3 and Q4 of 2022, causing trailing EPS to contract faster than market share quotations. Consequently, near cyclical market lows during Q4 of 2022, trailing P/E expanded above 20.0 times. Investors purchasing shares at a P/E multiple of 6.0 times during 2021 absorbed severe portfolio drawdowns, whereas those waiting for P/E to drop below 10.0 times during 2022 missed the accumulation bottom.

| Financial Year HPG | Net Revenue (VND bn) | Net Profit After Tax (VND bn) | Year-End P/E (x) | Year-End P/B (x) |
|---|---|---|---|---|
| FY 2021 | 149,680 | 34,521 | 6.0 | 2.1 |
| FY 2022 | 141,409 | 8,444 | 21.5 | 1.2 |
| FY 2023 | 120,355 | 6,800 | 18.2 | 1.5 |
| FY 2024 | 140,560 | 12,020 | 14.8 | 1.6 |

According to official earnings releases published by Hoa Phat Group on 24/01/2025, consolidated net revenue for fiscal 2024 reached VND 140,560 billion, up 17.0% from 2023. Net profit after tax recovered to VND 12,020 billion in 2024, climbing 77.0% from VND 6,800 billion in 2023. With operating recovery taking hold, trailing P/E normalized to 14.8 times at the close of 2024. See the full text at [Industry and Trade Magazine](https://tapchicongthuong.vn/hoa-phat-lai-sau-thue-12-020-ty-dong-nam-2024-132731.htm).

Regarding price-to-book ratios, according to audited consolidated statements for fiscal 2024, total assets reached VND 224,439 billion while equity stood at VND 114,647 billion as of 31/12/2024. Construction-in-progress on Dung Quat 2 reached VND 60,108 billion as of 31/12/2024, representing 26.8% of total assets. Once operational, these blast furnaces trigger substantial fixed asset depreciation expenses, requiring high plant utilization to preserve profit margins.

## Four Scenarios Where P/E and P/B Distort Corporate Reality

Based on historical market evidence, equity analysts categorize four structural mechanisms where P/E and P/B ratios mislead observers:

First, low P/E multiples at cyclical peaks. According to Ginity historical market studies across 2020-2024, commodity manufacturers in steel, chemicals, and fertilizers exhibit trailing P/E multiples below 7.0 times precisely at cycle earnings peaks. When selling prices soften, sharp earnings drops promptly elevate multiples to extreme levels.

Second, non-core one-off earnings distorting trailing multiples. When a corporation registers extraordinary investment gains from offloading an associate company or real estate land use rights, trailing EPS surges, compressing P/E. Without adjusting for non-recurring income, investors misunderstand core operational earning power.

Third, the low P/B trap caused by impaired inventories and uncollectible receivables. According to corporate financial analysis standards in 2024, trading at a low price-to-book multiple offers a genuine margin of safety only if stated asset carrying values match liquidation reality. Obsolete inventories or aged delinquent receivables mean stated book equity is already eroded.

Fourth, excessive debt leverage distorting equity safety. Companies employing excessive short-term bank debt risk severe liquidity shocks when interest expenses adjust, diminishing the reliability of stated book value as a downside floor. Investors track balance sheet leverage metrics across Ginity's [market valuation tracker](/en/markets).

## Verifying Book Value and Multiples Across Regulated Exchanges

To navigate valuation traps, investors review primary source filings and assess balance sheet asset quality directly.

Under VNX Decision 22/QD-HDTV dated 16/03/2026 regarding listing rules and Circular 96/2020/TT-BTC issued by the Ministry of Finance, issuers on HOSE and HNX must disclose complete notes regarding inventory valuation policies, capital projects in progress, and loan schedules. See the full text at [Vietnam Exchange](https://vnx.vn/van-ban-phap-ly/6) and [Ministry of Finance](https://vbpl.vn/van-ban/chi-tiet/thong-tu-so-96-2020-tt-btc-huong-dan-cong-bo-thong-tin-tren-thi-truong-chung-khoan--146048).

Investors can directly navigate the following official registries to inspect financial filings firsthand:

- State Securities Commission IDS Portal: Access the regulatory filing directory, enter ticker HPG into the symbol query box, select document category "Financial Statements", choose period "Year 2024", and open the PDF. Readers will see the reported Note on Construction in Progress verifying the VND 60,108 billion allocation to Dung Quat 2. See the full text at [State Securities Commission of Vietnam](https://congbothongtin.ssc.gov.vn/).
- HOSE Disclosure Portal: Open the exchange corporate filings page, filter by ticker HPG, and retrieve executive earnings commentary alongside quarterly performance disclosures. See the full text at [Ho Chi Minh Stock Exchange](https://www.hsx.vn/vi/tin-tuc/cong-bo-thong-tin).
