VinFast Reports Thursday With Losses Widening and Alternative Signals Turning Bearish

Note: These figures reflect diluted GAAP earnings per share, reported before non-recurring items, and may differ from the non-GAAP figures used by some sources.

Part 2.1: Price Behavior Around Earnings

VinFast Auto has not consistently disclosed whether it reports before market open or after market close, making the interpretation of Day 0 versus Day +1 moves variable across reporting periods.

VFS has demonstrated significant volatility around earnings releases, with an average absolute Day 0 move of 3.96% and an average Day 0 range of 6.31%. The historical pattern shows considerable variation, with Day 0 moves ranging from a 7.58% decline (September 2024) to a 4.98% drop (June 2026), though the stock has also posted positive reactions including a 4.39% gain in June 2025.

The follow-through action on Day +1 has been more muted but still meaningful, averaging a 2.32% absolute move with a 4.68% range. Notably, the November 2024 earnings showed unusual behavior with a modest Day 0 reaction (+0.51%) followed by a substantial Day +1 surge of 7.85%, suggesting delayed processing of results or guidance. More typically, Day +1 moves have been relatively contained, often showing modest declines as initial reactions stabilize.

Investors should prepare for material price swings around tomorrow's release, with historical data suggesting moves in the 4-6% range are common on the day of the report. The pattern of consistent earnings misses correlating with negative Day 0 reactions in recent quarters (June 2026: -4.98%, November 2025: -6.78%) suggests the market has been punishing execution shortfalls, making the magnitude of any potential miss particularly important for near-term price action.

Part 2.2: Options Market Expected Move

The options market is pricing in an expected move of 14.21% (±$0.44) through the September 18th expiration, which is substantially higher than the average historical Day 0 move of 3.96%. This elevated implied volatility of 118.71% suggests options traders are anticipating significantly more dramatic price action than VFS has typically delivered on earnings day, possibly reflecting heightened uncertainty about the company's operational trajectory or expectations for material guidance changes.

Part 3: What Analysts Are Saying

Analyst sentiment on VinFast Auto leans bullish but with notable caution, reflected in an average recommendation of 4.20 (Buy). The current consensus includes 3 Strong Buy ratings and 2 Hold ratings, with no sell recommendations among the 5 analysts covering the stock. This rating structure has remained unchanged over the past month, indicating stable analyst conviction despite the company's pattern of earnings misses.

The average price target of $5.50 implies substantial upside of approximately 77% from the current price of $3.11, with estimates ranging from a low of $5.00 to a high of $6.00. This wide gap between the current trading price and analyst targets suggests the Street believes VFS is significantly undervalued relative to its long-term potential, though the lack of rating upgrades despite this apparent discount may reflect skepticism about near-term catalysts or execution risk.

The absence of any sell ratings is notable given the company's consistent pattern of missing estimates and ongoing losses. This suggests analysts are willing to look through near-term operational challenges and focus on VFS's positioning in the growing global EV market, particularly its potential in Southeast Asian markets where competition is less intense than in North America and Europe. However, the presence of 2 Hold ratings (40% of coverage) indicates not all analysts are convinced the risk-reward is favorable at current levels, likely reflecting concerns about cash burn, production scaling challenges, and the company's ability to compete against better-capitalized rivals.

Part 4: Technical Picture

The Barchart Technical Opinion currently shows a 48% Sell signal, representing a modest improvement from last week's 56% Sell reading but unchanged from the 48% level seen a month ago. This suggests the technical picture has stabilized recently after showing some weakness, though the overall signal remains cautionary heading into earnings.

Timeframe Analysis:

• Short-term (50% Sell): Moderate sell signal indicates near-term momentum is slightly negative, suggesting tactical weakness in the immediate trading environment
• Medium-term (75% Sell): Strong sell signal reflects more pronounced weakness in the intermediate timeframe, indicating the stock is struggling to establish upward momentum over a multi-week horizon
• Long-term (50% Sell): Moderate sell signal shows the longer-term trend is also tilted to the downside, though less severely than the medium-term picture

Trend Characteristics: The technical environment is characterized by a Soft Weakening trend, suggesting the stock is experiencing gradual deterioration in momentum rather than sharp selling pressure, which creates an uncertain backdrop for absorbing earnings results.

VFS is trading at $3.11, positioned below its 5-day moving average of $3.12, above its 10-day average of $3.11, and below its 20-day average of $3.14. More significantly, the stock is trading below both its 100-day moving average of $3.44 and 200-day moving average of $3.40, indicating the longer-term trend remains negative. The stock is essentially on its 50-day moving average of $3.11, suggesting this level may serve as a pivot point for post-earnings direction. The clustering of the stock near multiple short-term moving averages while remaining well below longer-term averages creates a technically fragile setup heading into earnings—a positive surprise could trigger a breakout above near-term resistance, while another disappointing result could accelerate the downtrend given the lack of technical support and already-negative medium-term momentum signals.
