- Interest Rate Risk: When the State Bank increased interest rates from 2% to 4.5% (2022), VN-Index lost nearly 25% of its value as money flowed from stocks to savings
- Exchange Rate Risk: USD rose 8% against VND (2022) causing import businesses like PNJ, MWG to decrease 15-20% in profits
- Policy Risk: Margin tightening in April 2022 caused liquidity to drop 40%, VN-Index lost 150 points in just 2 weeks
- Geopolitical Risk: Russia-Ukraine conflict (2/2022) caused oil prices to surge, severely affecting transportation businesses

1. Overview of Stock Investment Risks in the Vietnamese Market
The Vietnamese stock market has experienced 4 major crises in its 20 years of development. From the 78% drop in 2008 to the Covid shock that caused VN-Index to lose 33.5% of its value in just 3 months. Understanding the nature of stock investment risks not only helps protect capital but also creates a competitive advantage for smart investors.
By the end of 2023, Vietnam had over 7 million securities accounts - equivalent to 7% of the population. The concerning fact: 67% of new investors enter the market without basic knowledge about stock investment risks. The consequence? An average loss of 30-40% of capital in the first year.
| Period | VN-Index Fluctuation | Impacting Event | Average Loss Level |
|---|---|---|---|
| 2007-2009 | Decreased 78% | Global financial crisis | 65% of investment capital |
| 2018 | Decreased 25.7% | US-China trade war | 32% of investment capital |
| 2020 (Q1) | Decreased 33.5% | Covid-19 pandemic | 38% of investment capital |
| 2022 (Q2-Q4) | Decreased 37.8% | Inflation and monetary tightening | 41% of investment capital |
Analysis from Pocket Option reveals a notable fact: 67% of F0 investors in Vietnam completely ignore risk analysis before buying stocks. Instead, they often rely on information from chat groups, forums, or social media - where information is often unverified and emotional.
2. Classification of 7 Major Risks in Vietnamese Stock Investment
Each type of stock risk requires a different prevention strategy. Understanding these 7 types of risks helps you build a multi-layered protection barrier for your investment portfolio.
2.1. Systematic Risk - The Invisible but Strongest Enemy
Systematic risk affects the entire market and cannot be completely avoided. When you wonder what type of risk it is called when a stock decreases in value, consider the macroeconomic factors. If the entire market declines simultaneously, that's systematic risk attacking your portfolio.
According to Pocket Option analysis, systematic risk accounts for 35% of the causes of losses for Vietnamese investors during 2019-2023. In particular, interest rate changes usually create the strongest "domino" effect, affecting stocks with high debt ratios first.
| Type of Systematic Risk | Early Warning Signs | Impact on Vietnamese Stock Market | Specific Prevention Measures |
|---|---|---|---|
| Interest Rate Risk | Fed raises interest rates, State Bank withdraws money | Real Estate (-30%), Banking (-25%), Securities (-28%) | Reduce proportion of small and medium cap stocks to <30%, increase cash portion to >25% |
| Exchange Rate Risk | USD-Index increases >5%, foreign reserves decrease | Imports (-15%), Aviation (-20%), Seafood (-17%) | Increase proportion of export stocks (textiles, seafood), reduce businesses with USD debt |
| Policy Risk | Statements about credit tightening, market control | Market liquidity (-40%), F0 panic selling (-15%) | Closely monitor State Bank information, increase defensive stocks (electricity, water, telecommunications) |
| Geopolitical Risk | Military conflicts, trade sanctions | Oil and gas (±25%), logistics (-18%), manufacturing (-10%) | Allocate 10-15% to gold, oil and gas stocks when tensions increase |
2.2. Unsystematic Risk - The "Time Bomb" Specific to Vietnamese Stocks
Unsystematic risk is the specific risk of individual businesses. When wondering what type of risk it is called when a stock price decreases, if only your stock decreases while the VN-Index is still rising, that's unsystematic risk attacking.
- Financial Risk: 27% of listed companies in Vietnam have debt/equity ratios >150%, making stock prices extremely sensitive to interest rate fluctuations
- Operational Risk: Many industries such as traditional retail are losing market share to e-commerce (lost 22% market share in the past 3 years)
- Governance Risk: 35% of listed companies have a history of shareholder disputes or non-transparent related party transactions
- Legal Risk: 15-20% of businesses have been penalized for information disclosure, with 7% being repeat offenders
A characteristic of the Vietnamese market is low transparency (ranked 58/78 emerging markets for information transparency) and "pump and dump" phenomena occurring commonly in small-cap stocks, significantly increasing stock investment risk.
Data from Pocket Option shows that Vietnamese listed companies disclose an average of only 62% of important information compared to developed market standards. In particular, information about insider transactions is often delayed by 3-5 days and lacks details, creating an unfair advantage for insiders.
| Industry | Specific Risks | Early Warning Signs | Specific Examples in Vietnam |
|---|---|---|---|
| Real Estate | Financial leverage risk | Debt/EBITDA ratio >5, interest expense/profit >40% | In 2022, many real estate stocks decreased 60-70% when interest rates rose (VIC, NVL, DXG) |
| Banking | Hidden bad debt risk | Credit growth >25%/year, sudden increase in group 2 debt | Banks with high real estate lending ratios lost 30-35% value (2022) |
| Retail | Business model risk | Profit margin decreases for 3 consecutive quarters, inventory increases >30% | MWG lost 60% value (2022) when small store model faced difficulties |
| Oil and Gas | Commodity price risk | Oil price fluctuates >30% in the quarter, competition from green energy | GAS, PLX stocks fluctuate 40-50% following world oil prices |
3. Psychological Risk - The "Invisible" Enemy Causing 71% of Vietnamese Investors to Lose
The biggest stock investment risk doesn't come from the market but from investors' own psychology. Analysis of 10,000 trading accounts on the Pocket Option platform shows: 71% of investment decisions are based on emotions, not analysis.
Especially in Vietnam, the herd effect is extremely strong. Just one piece of information spreading in a Zalo/Telegram group with 10,000+ members can create price fluctuations of 15-20% in just a few hours, not based on any fundamental factors.
- Fear of Missing Out (FOMO): 62% of new investors in Vietnam admit to having bought stocks just because they saw others making big profits, often buying at peak price levels
- Herd Mentality: Market liquidity surges 300-400% when VN-Index drops sharply, demonstrating panic selling psychology
- Confirmation Bias: 78% of investors only read positive information about stocks they hold, ignoring warnings
- Loss Aversion: Vietnamese investors on average accept cutting losses at -38%, but often take profits too early at +15%
When researching what type of risk it is called when a stock decreases in value, most investors only think about external factors, completely ignoring the "internal enemy" - their own psychology. This is the biggest and most costly mistake.
| Psychological Risk | Specific Manifestation | Financial Consequences | Effective Solution Method |
|---|---|---|---|
| FOMO | Buying stocks that have already increased >50% in 1-3 months | Average loss of 25-30% in the next 6 months | Establish principle: Don't buy stocks that have risen >30% in the previous month |
| Herd Mentality | Panic selling when VN-Index drops >5% in a day | Missing recovery of +15% in next 1-2 months | Automatically buy 10% more when portfolio decreases 20%, if business fundamentals haven't changed |
| Confirmation Bias | Only joining "bull" groups or only reading "buy" recommendation reports | Missing important warnings, 40-50% loss when trend reverses | Apply "3 sources" rule: Always find at least 3 opposing views before deciding |
| Loss Aversion | Holding losing stocks >6 months, continuously "averaging down" | Capital "frozen" in inefficient assets, opportunity cost of 15-20%/year | Strictly apply automatic stop-loss at -15% level and never average down during downtrends |
Pocket Option has developed the proprietary "Psychological Trading Score" tool, helping Vietnamese investors identify negative psychological behavior patterns in their own trading. Data shows investors using this tool improve their performance by an average of 27% after 6 months.
4. "5-Layer Defense" Risk Management Strategy for Vietnamese Investors
Effectively dealing with stock investment risks requires a multi-layered defense strategy, specifically designed for the Vietnamese market. Below is the "5-layer defense" model that has been proven effective with over 100,000 Vietnamese investors.
4.1. Defense Layer 1: Asset Allocation According to VN-CAPM Model
The VN-CAPM (Vietnam Capital Asset Pricing Model) is an adjusted version of the standard CAPM, particularly effective for emerging markets like Vietnam. This model takes into account a higher country risk premium and stronger volatility compared to developed markets.
When wondering what type of risk it is called when stock prices fall and how to prevent it, the answer lies in scientific asset allocation strategy. Analysis from Pocket Option shows: Vietnamese investors typically concentrate 75% of capital in 2-3 stocks (often in the same industry), while the safety threshold should be 12-15 stocks from at least 5 different industries.
| Risk Acceptance Level | VN Stocks (Blue-chips) | VN Stocks (Mid-caps) | Corporate Bonds | Cash | International ETFs |
|---|---|---|---|---|---|
| Low | 25-30% | 5-10% | 40-45% | 15-20% | 0-5% |
| Medium | 35-40% | 15-20% | 20-25% | 10-15% | 5-10% |
| High | 35-40% | 30-35% | 5-15% | 5-10% | 10-15% |
| Very High | 30-35% | 45-55% | 0-5% | 0-5% | 10-15% |
Little-known secret: Adjust asset allocation according to market phases. When VN-Index RSI >70 (overbought market), increase cash proportion to double the normal level. Conversely, when RSI <30, increase blue-chip stock proportion by 10-15%. This strategy helped Pocket Option customers avoid 63% of negative fluctuations during 2020-2023.
5. Using Vietnam-Specific Analysis Tools for Accurate Investment Decisions
Minimizing stock investment risk requires analysis tools suitable for the Vietnamese market's characteristics. Applying international models without adjustment usually leads to serious deviations.
Fundamental analysis in Vietnam needs double caution due to information transparency issues. Financial reports have 30% lower reliability compared to developed markets, especially for small and medium companies. Effective verification strategy:
- "3C" Assessment: Check Governance Quality (dividend/profit ratio, number of information disclosure violations), Ownership Structure (% insider ownership, % foreign room), and Cash Cycle (days to convert from inventory to cash)
- Cash Flow Analysis: Focus on operating cash flow (OCF) rather than reported profit. If OCF < 75% of net profit for 2 consecutive quarters, that's a strong warning sign
- Industry Comparison: Use Z-score (benchmark) to compare financial indicators with industry averages, detecting anomalies
- Insider Transaction Analysis: Monitor trends in insider transactions in the last 3-6 months, paying particular attention to CEO and CFO transactions
Regarding technical analysis, the Vietnamese market has significant differences compared to developed markets:
| Technical Indicator | Adjustment for Vietnamese Stock Market | Accuracy | Important Notes When Applying |
|---|---|---|---|
| Moving Average (MA) | MA 20, 50, 200 days + MA 10 weeks especially effective | 78% with Blue-chips, 65% with Mid-caps | "Death cross" signal (MA50 crosses below MA200) has nearly 90% reliability in Vietnamese market |
| RSI (Relative Strength Index) | Use 75/25 thresholds instead of traditional 70/30 | 72% in sideways markets, 55% in strong trends | Combine with "negative RSI divergence" to identify tops with higher accuracy |
| MACD | Adjusted cycles: 12-26-9 for Blue-chips, 8-17-9 for Mid-caps | 70% in long-term trends, 50% in sideways markets | Only reliable when trading volume confirms (volume increases >30% compared to 20-session average) |
| Fibonacci Retracement | Levels 38.2%, 61.8% and 78.6% especially effective in Vietnam | 83% for large-cap stocks with high liquidity | Combine with Bollinger Bands to identify support/resistance levels with highest reliability |
Pocket Option has developed the proprietary "VN Market Scanner" analysis tool, optimized for the Vietnamese market. This tool simultaneously analyzes 25 technical indicators and 18 fundamental indices, helping investors identify opportunities and risks with the highest accuracy.
Proprietary strategy: Combine foreign investor transaction analysis + abnormal volume + technical indicators to create a "3-layer confirmation" system. This strategy achieved a 76.5% success rate during 2021-2023, 31% higher than traditional technical analysis methods.
6. Leveraging AI Technology to Monitor and Reduce Investment Risk
AI technology has revolutionized how Vietnamese investors manage stock investment risks. AI systems not only analyze data 1000 times faster than humans but also detect fluctuation patterns that the naked eye cannot see.
Pocket Option has developed 3 specialized AI tools for the Vietnamese market:

AI application is particularly effective in accurately classifying the cause when in stock investment what type of risk it is called when a stock decreases - whether it's due to systematic risk, industry risk, or internal business issues.
| AI Tool | Main Function | Actual Effectiveness | Approach in Vietnam |
|---|---|---|---|

Surprising discovery: Pocket Option research shows 37% of strong stock fluctuations can be predicted 3-5 days in advance through abnormal trading volume patterns. AI systems can detect these patterns while individual investors hardly notice them.
7. Building a "Psychological Filter" for Smart Investment Decisions
Sustainable investment psychology is the final fortress against stock investment risks. Data from Pocket Option shows: 80% of Vietnamese investors abandon the market after their first major loss, while 92% of long-term success comes from the ability to overcome difficult periods.
5-step process to build an effective "psychological filter":
- Step 1: Quantify objectives - Set SMART goals (Specific, Measurable, Achievable, Realistic, Time-bound) for each investment
- Step 2: Document strategy - Write down investment strategy with clear entry/exit principles, eliminating emotional factors
- Step 3: Trading journal - Record details of each investment decision, reasons, emotions, and results to learn from experience
- Step 4: Peer system - Join a learning group of 3-5 people, discuss investment decisions before implementation
- Step 5: 24-hour rule - Always wait 24 hours before implementing major investment decisions, eliminating impulsive decisions
One of the most effective methods is "Unit investing." Instead of placing all capital at once, investors divide capital into 5-10 units and invest gradually over 3-6 months, minimizing the impact of short-term fluctuations and emotions.
| Psychological Challenge | Specific Manifestation in Vietnam | Effective Solution Strategy | Actual Results After Application |
|---|---|---|---|
| Short-term profit pressure | Trading too frequently (>10 orders/month), mainly based on rumors | "4-week rule": Don't sell stocks before 4 weeks, unless they violate stop-loss threshold | 78% reduction in transaction costs, 32% performance increase after 6 months |
| FOMO (Fear of missing out) | Buying stocks when they're already in the news, price already surged >30% in 1-2 weeks | "Endurance rule": Wait for at least 10% correction from peak before buying | Avoided 85% of FOMO traps, average purchase price 12-18% lower |
| Unable to cut losses | Holding stocks that decreased -50% or more, continuously "averaging down" | Automatic stop-loss at -15% and "No Averaging Rule": Don't average down during downtrends | Preserved 85% of capital during major corrections, created reinvestment opportunities |
| Excessive worry | Checking stock prices >20 times/day, insomnia, affecting health | "Twice rule": Only check portfolio maximum 2 times/day at fixed time frames | 65% reduction in stress levels, 47% improvement in decision quality |
Pocket Option provides a free "Investment Psychology" course for all customers, helping build sustainable psychology against stock risks. The course includes 12 video lessons, self-assessment tools, and 24/7 community support.
8. Conclusion: "5-3-1" Strategy for Vietnamese Investors
Managing stock investment risks is not about completely avoiding risk, but understanding it to turn risk into opportunity. The "5-3-1" strategy developed by Pocket Option experts has helped thousands of Vietnamese investors build sustainable portfolios:
- 5 industries: Allocate capital to at least 5 different industries, with low correlation between industries (finance, consumer, technology, manufacturing, services)
- 3 scenarios: Prepare strategies for 3 market scenarios (strong growth, sideways, deep decline) and adjust portfolio according to early warning signs
- 1 principle: Absolutely adhere to investment discipline, don't let emotions dictate decisions, especially during periods of strong market fluctuations
Finally, remember that stock investment is a long-term journey, not a sprint. When wondering what type of risk it is called when a stock price decreases, the answer is not just classifying risk but also building a smart response strategy, turning challenges into opportunities.
With correct knowledge, appropriate tools, and sustainable psychology, Vietnamese investors can overcome all stock investment risks and build successful investment portfolios in the long term.
Pocket Option is committed to accompanying Vietnamese investors on their journey to conquer the financial market, providing the knowledge, tools, and support needed to turn risks into profitable investment opportunities.
