Short Selling in Vietnam: Opportunities and Limitations

Both billion-dollar funds and individual traders use short selling to profit in downtrends. In Vietnam, however, the picture is far more complex. Understanding the regulatory barriers and niche opportunities not only helps investors avoid unnecessary risks but also unlocks strategies for optimizing returns across every phase of the economic cycle.

What Exactly Is Short Selling?

Short selling, or bán khống, is the act of selling an asset you do not own, with the expectation of buying it back at a lower price later.

If the price falls as anticipated, you buy back cheaper and keep the difference. If the price rises, you must buy back at a higher price and absorb the loss.

The mechanism involves 4 steps:

It is important to note that when buying a stock, your maximum loss is limited to the amount invested, since prices cannot fall below zero. When short selling, prices can rise indefinitely — meaning theoretical losses are uncapped. This is precisely why short selling is universally regarded as a tool demanding a far higher standard of risk management discipline.

The Truth About Stock Short Selling: A "Closed Game" for Retail Investors

On Wall Street, borrowing a stock to short takes just a few clicks. In Vietnam, Direct Stock Short Selling remains out of reach for the vast majority of individual investors.

• Regulatory and infrastructure barriers: Vietnam's stock market has not yet formally licensed direct short selling of underlying equities for retail investors.
• An institutional privilege: A very small number of financial institutions, securities companies, or investment funds may access Securities Borrowing and Lending (SBL) arrangements — but the process is closed, requires massive asset scale, and is not commercially available to the public.
• The "gray market": Informal pools of securities do exist, allowing individuals to borrow shares for short positions. However, these are unofficial gray-market transactions carrying extreme counterparty risk, predatory borrowing costs, and significant legal exposure.

The consequence: When the VN-Index enters a deep correction, most retail investors are left with only two passive options: hold through the pain or sell in panic and exit the market.

2. VN30F1M Futures: The Gateway to Shorting the Market

When the door to the underlying market is closed, the derivatives market opens a transparent, highly liquid escape route. The VN30 Index Futures contract (VN30F1M) is the most practical instrument available today for investors seeking to profit when the market declines.

Rather than short selling a specific stock, you open a Short position across the entire basket of the 30 largest bluechip stocks on the market. This instrument delivers two strategic advantages for sophisticated investors:

• Hedging an underlying portfolio: When macroeconomic risks emerge, instead of liquidating fundamentally strong long-term holdings — and losing the advantage of a low cost basis — investors open a Short VN30F1M position. Profits from the derivative short directly offset losses in the underlying equity portfolio.
• Speculating on a trend reversal: Placing a direct directional bet on a broad market decline by leveraging the high leverage of derivatives to maximize return on investment when a clear thesis exists.

That said, trading VN30F1M demands strict risk management discipline and lightning-fast reaction times in a market that moves second by second.

3. Alpha Stock VN: The Quantitative Solution for Systematically Capturing Both Sides of the Market

The structural disconnect between the underlying and derivatives markets creates a difficult puzzle: how do you hold stocks with individual growth stories while automatically hedging when the broader market unexpectedly collapses?

This is precisely what sets Alpha Stock VN apart — the flagship strategy of the AlphaSet quantitative investment platform. Rather than leaving investors to wrestle with emotional decisions or monitor trading screens around the clock, Alpha Stock VN solves this problem end-to-end through automation and big data:

• Parallel Long/Short strategy: The algorithm continuously scans the market to identify and Long (buy/hold) the stocks with the highest alpha — strong fundamentals, robust money-flow momentum. Simultaneously, when quantitative models signal systemic risk, the system automatically activates Short VN30F1M positions to protect the underlying asset base.

• Fully automated via API: A completely hands-free investment experience. Simply subscribe to an AlphaSet plan and connect it to your DNSE account. All analysis and order execution is then handled automatically by the system, directly within that account. Every decision — taking profit, cutting losses, opening or closing hedge positions — is executed by the algorithm in an instant, entirely eliminating psychological blind spots such as fear and FOMO.

• Freedom from uptrend dependency: Your portfolio is no longer held hostage to the axiom that "you can only profit when the market goes up." By systematically capturing both sides of the market, investment performance is smoothed out, minimizing drawdown risk during periods of market panic.

Short selling in Vietnam is not for novices looking to gamble on a trading screen. But with a disciplined allocation to VN30F1M and a sharp quantitative engine like Alpha Stock VN, retail investors can now equip themselves with the same sophisticated tools that were once the exclusive domain of professional investment funds.
