Behavior gap: the distance between fund returns and investor returns

What is the behavior gap?

The behavior gap is the difference between the return of an asset or investment strategy and the actual return that investors receive from that asset. This gap arises from buying and selling at the wrong times.

If a fund returns 15% a year, does the person who puts money into it earn 15%?

Only if that person stayed in the fund from start to finish. In practice, investors deposit and withdraw at different points in time, and those timing decisions create the gap.

The performance figure a fund publishes is calculated over the full period, assuming someone held from day one to the very last day. The figure you actually receive depends on which days your money was in the fund.

If most of your money was present during the down periods and absent during the up periods, your outcome will fall short of the fund's reported return — even though you chose the right fund.

The mechanism, in brief:

When a fund or stock surges, media coverage follows, people talk about it, and capital pours in at elevated prices. When that fund subsequently corrects and declines, many investors panic and redeem at lower prices. The result is that they buy high and sell low — even though the fund itself generates solid long-term returns for anyone who held from beginning to end.

Why is the behavior gap often wider in Vietnam?

Vietnam's stock market experiences far greater price swings than developed markets. A stock can rise 50% over a few months and then fall 40% shortly after. This volatility amplifies the behavior gap: investors who enter late after a strong rally absorb the full brunt of the subsequent decline, while those who held from the start already had a cushion built up during the earlier advance.

In addition, Vietnam's investment community tends to share information through group chats, and that information typically reaches individual investors long after institutions have already acted on it.

Alpha Stock VN closes the behavior gap through systematic execution

What is Alpha Stock VN?

Alpha Stock VN is a quantitative investment strategy for the Vietnamese stock market, developed by AlphaSet — a quantitative investment platform built for individual investors.

The AlphaSet team has over 10 years of experience developing quantitative trading strategies, has managed $80 million for funds in Dubai, UAE, and has processed a total of more than $200 million in assets across multiple market cycles, with over $10 billion in live trading volume since 2016.

AlphaSet serves traders ranging from professional to semi-professional, participating in digital asset markets (spot/futures/XAU) and the Vietnamese stock market, enabling individual users to trade automatically with impressive real-world APR.

Users do not need to know how to code, configure complex setups, or monitor charts continuously — they can still trade effectively through AlphaSet. Simply connect AlphaSet to your brokerage account via API, select the AlphaStock strategy, and let the system trade automatically 24/7.

Unlike buying and holding on your own, Alpha Stock VN scores and ranks securities in the VN30/VN100 universe using a multi-factor system, prioritizing stocks that are supported by large capital flows, while also using VN30F1M futures contracts to trade both directions or hedge when the market declines.

How does Alpha Stock VN work?

Instead of spending your own time researching hundreds of stocks, reading financial reports, and sitting at a screen to place orders manually, you simply subscribe to an AlphaSet plan and connect it to your DNSE account. The entire analysis and order-execution process is then handled automatically by the system, directly within that account.

AlphaSet's algorithm scores and ranks securities in the VN30/VN100 universe based on four signal groups: technical, fundamental factors, foreign institutional flows, and market sentiment. From that ranking, a single capital allocator splits funds between two segments:

• Underlying equities: Only the strongest-ranked stocks are purchased, traded on a T+1.5 settlement cycle.
• VN30F1M derivatives: Long or short positions taken in line with the trend, with approximately 5.4× leverage. For derivatives trading, the engine combines trend signals and technical signals to determine when to go long and when to go short.

Every decision is data-driven, each position carries a pre-defined stop-loss level, and execution is fully automated — unaffected by emotions or market rumors during periods of volatility. The objective is not to beat the market on any single session, but to accumulate alpha (excess return above the market) consistently across multiple cycles — something most individual investors trading manually find extremely difficult to achieve.

Your assets remain yours at all times. Your capital always stays in your own brokerage account; AlphaSet has no ability to withdraw or transfer funds. The authorization only permits order placement, and you can revoke it at any time directly within the account management application.
