Why Are Stocks "Put Under Restriction"? Understanding the True Meaning of Disposition Stocks

If you’ve encountered this situation in the stock market: a certain stock surges over 100% in just one month, seemingly with unlimited prospects, but when you want to buy in, you find it cannot be executed quickly, and even margin trading and securities lending are disabled. Congratulations, you’ve discovered a disposal stock. So, what exactly does “disposal” mean? Are these stocks still worth investing in? This article will provide a comprehensive analysis.

First, look at a case study: Two very different fates of disposal stocks

In June 2021, Weifu Electronics (6756) was listed as a disposal stock due to excessive price increase and abnormal trading. Despite trading restrictions, the stock continued to rise against the trend during the disposal period, accumulating a 24% increase, and eventually recovered to continue its upward trend.

At the same time, A-Ming (2609) also entered the disposal list for similar reasons. But the story took a sharp turn—at the end of July, the stock price plummeted, and it was listed as a disposal stock again, this time due to “a large decline over the past 6 days.” Subsequently, the stock performance remained sluggish for a long time.

These two cases reveal an important truth: Being listed as a disposal stock is not a death sentence; the key lies in the company’s own quality.

Definition of disposal stock: A “temporary notice” for abnormal trading

A disposal stock, officially called “disposal shares,” refers to a temporary regulatory measure by the Taiwan Stock Exchange against stocks with abnormal trading conditions. When a stock exhibits the following anomalies in a short period, it may be listed as:

• Abnormal price fluctuation: Price change exceeding 100% over 30 trading days
• Abnormal trading volume: Significantly increased trading volume over the past 6 days
• High turnover rate: Daily turnover rate exceeding 10%

Stocks listed as disposal stocks will first enter the “Attention Stock” stage (only a warning, trading is not restricted). If abnormal conditions persist, they will escalate to “Warning Stock” and simultaneously enter the “Disposal Stock” list, at which point trading restrictions are imposed.

The three stages of trading restrictions for disposal stocks

Normal stocks vs. disposal stocks: a comparison overview

First Disposal: “Light Restrictions”

Stocks entering the first disposal stage will have their trading matched every 5 minutes. When a single buy or sell order exceeds 10 lots or accumulates over 30 lots, “circle storage trading” must be used— the system will verify in real-time whether your account has sufficient funds, and insufficient amounts will block the transaction. In contrast, normal stocks enjoy the convenience of T+2 deferred payment.

Second Disposal: “Severe Restrictions”

If the stock remains highly volatile and meets disposal criteria again within 30 days, it enters the second disposal stage. At this point, matching intervals extend to 20 minutes, and regardless of trading volume, all transactions must use circle storage trading. These measures sharply reduce liquidity, often causing trading volume to plummet.

Explanation of disposal period

Under normal circumstances, the disposal period lasts for 10 trading days. However, if the intraday cancellation volume accounts for more than 60% of total volume during the disposal period, the period will be extended to 12 trading days. After expiration, the stock automatically exits the disposal list.

Three-tier grading system: the evolution path from normal to disposal

The “downgrade journey” of a stock usually follows this pattern:

Normal Stock → Attention Stock → Warning Stock → Disposal Stock

• Normal Stock: No restrictions; margin trading and day trading allowed
• Attention Stock: Risk warning issued, but trading remains unrestricted (equivalent to normal trading)
• Warning Stock: Continuous abnormal trading conditions, regulatory attention begins
• Disposal Stock: Entering a phase of substantial trading restrictions, subject to all the rules mentioned above

Can disposal stocks still rise? How to judge investment value

The subsequent trend of disposal stocks varies by case; success or failure depends on fundamentals rather than regulatory labels.

Why do some say “disposal stocks get bigger and bigger”?

There is logic behind this market saying. Some stocks listed as disposal stocks are often hot targets that surged significantly earlier. During the disposal period, due to decreased liquidity and trading difficulties, the chips tend to stabilize. Once restrictions are lifted after the disposal period, the suppressed buying interest may be released in a concentrated manner, causing the stock price to rise again.

But this is an ideal scenario. If, during disposal, the stock faces short-selling forces or deteriorating fundamentals, investors face high risks—because escaping becomes difficult due to trading restrictions.

Investment decision framework for disposal stocks

Step 1: Assess fundamentals

• Does the company’s core competitiveness still exist?
• Are financial trends healthy (revenue, gross margin, net profit, etc.)?
• Are there significant operational risks or negative events?

Step 2: Analyze the chip (ownership) side A major advantage during disposal is that, due to bans on margin trading and securities lending, the movement of major funds is relatively “clean,” allowing clearer observation of institutional buying and selling intentions. By examining closing data, judge whether to follow the trend.

Step 3: Confirm entry timing

• Is the stock price during disposal consolidating sideways (not continuously falling)?
• Is the current stock price reasonable or undervalued?
• If the stock price has fallen sharply, it’s better to avoid entering.

Step 4: Evaluate risk tolerance Disposal stocks tend to be more volatile and riskier. Short-term investors suffer the most from inability to day trade; long-term investors are less affected by trading restrictions and can focus more on fundamentals.

Is long-term holding suitable for disposal stocks?

It depends on four factors:

Factor 1: Company quality Unusual trading may hint at underlying issues. If the company operates well and finances are stable, disposal is just a temporary disturbance; if the company has problems, long-term holding entails significant risk.

Factor 2: Market environment In a declining overall market, disposal stocks carry higher risks; in a bull market, they may present better opportunities.

Factor 3: Your investment style Short-term traders suffer increased costs due to inability to day trade; long-term investors are unaffected, and may even benefit from timely financial disclosures mandated by listed companies.

Factor 4: Your psychological resilience Can you withstand 20%, 30%, or even larger short-term fluctuations? Investors with low risk tolerance should be cautious.

Final advice

Disposal stocks are merely a temporary label for abnormal trading, not an indicator of company quality. If you have solid research indicating the company still has investment value, then being a disposal stock should not be a reason to give up.

Conversely, if you already doubt the company’s prospects, entering a disposal stock period is a good reason for cautious observation and to stay on the sidelines. Remember: The best investment decisions are always based on in-depth understanding of the company itself, not short-term market noise.
