在整理 2020–2025 年跨市場資料後，可以進一步回答一個有趣的問題：
全球哪個市場的低價股最多？
低價股在不同市場的比例差異其實非常大。在某些市場中，低價股只是少數；但在另一些市場，低價股甚至可能構成整個市場的重要部分。
從多個市場資料觀察，低價股密度較高的市場通常包括：
1️⃣ 澳洲（ASX）
2️⃣ 加拿大（TSX / TSXV）
3️⃣ 英國（LSE）
這些市場的一個共同特徵是：
- 存在大量極低價格股票
- 市場允許非常小的公司上市
- 許多股票長期停留在幾分錢的價格區間
例如在部分市場中，可以看到股票價格長期落在：
- 0.05
- 0.03
- 0.01
- 甚至 0.003
在這些情況下，低價股不再只是市場邊緣，而是整體市場結構的一部分。
相較之下，一些亞洲市場的低價股比例則明顯較低，例如：
- 日本
- 韓國
- 台灣
這些市場的上市制度與 tick size 設計，使得極低價格股票相對較少。
為什麼某些市場每天都很多「50% 漲幅」？
許多投資人會注意到一個現象：
某些市場每天都出現大量 +50%、+100% 的股票。
乍看之下，這似乎代表市場非常瘋狂。
但實際上，在很多情況下，這只是市場結構造成的統計現象。
原因在於：
價格過低 + tick size 固定
當股票價格非常低時，最小跳動單位會占股價極高比例。
例如：
| 股價 | tick size | 單次跳動 |
|--------|-----------|----------|
| 100 | 0.1 | 0.1% |
| 10 | 0.01 | 0.1% |
| 1 | 0.01 | 1% |
| 0.1 | 0.01 | 10% |
| 0.02 | 0.01 | 50% |
| 0.01 | 0.01 | 100% |
一次最小跳動就可能造成 50% 漲幅。
因此某些市場看起來每天都有很多「暴漲股」，
實際上只是低價股與 tick size 結構造成的百分比放大。
一跳就 100% 的股票真的存在嗎？
答案是：
存在，而且並不少見。
在一些價格極低的股票中，例如：
- 0.01
- 0.005
- 0.002
如果市場最小報價單位仍然是 0.01，
那麼一次最小跳動就可能造成：
- 100%
- 200%
- 甚至更高
的價格變動。
這種情況在某些市場中並非理論案例，而是真實存在的交易結構。
最誇張的市場案例
在整理 2020–2025 的資料時，可以看到一些非常極端的例子。
以下是幾種常見的極端情況。
Case 1：One Tick = 2000%
在某些極低價股票中，可能出現：
股價：0.0005
tick size：0.01
這意味著一次最小跳動的百分比為：
2000%
這種情況雖然罕見，但在某些市場確實存在。
Case 2：Intraday Range 超過 500%
在低流動性的低價股中，日內振幅有時會非常誇張。
例如：
- 開盤 0.02
- 盤中高點 0.12
這種情況下：
intraday range = 500%
這並不一定代表公司基本面出現巨大變化，而可能只是：
- 流動性不足
- 報價跳動不連續
造成的價格波動。
Case 3：單日漲幅 1000% 以上
在極低價格區間，某些股票可能出現非常誇張的單日漲幅，例如：
- 前一日收盤：0.001
- 今日收盤：0.01
單日漲幅可能達到：
900%
甚至更高。
這些案例在一些低價股密集的市場中並非完全罕見。
為什麼這些案例很重要？
如果直接用「百分比漲幅」來做市場統計，很容易出現一種情況：
排行榜前幾名幾乎全部都是低價股。
此時排行榜反映的並不是市場真正的異動，而是：
- 低價股
- tick size
- 流動性結構
所共同造成的結果。
因此在進行跨市場比較、漲幅分布研究或 big move 分析時，
將低價股單獨處理，往往能讓統計結果更加接近市場的真實結構。
一個值得注意的觀察
不同市場的低價股比例與 tick size 設計組合，會產生完全不同的市場特徵。
例如：
有些市場低價股很多，但 tick size 設計較細，因此極端漲幅並不常見。
而另一些市場則同時具有：
- 大量低價股
- 粗糙的 tick size
在這樣的市場中，就更容易出現：
- 50% 漲幅
- 100% 漲幅
- 極端日內振幅
這些現象也解釋了為什麼不同市場在「極端行情排行榜」中呈現出截然不同的特徵。
全球最瘋狂的三個股票市場
整理 2020–2025 多個市場的資料後，可以看到一個非常有趣的現象：
不同市場在「極端漲跌」上的表現其實差異很大。
有些市場幾乎每天都能看到 50% 以上漲幅的股票，
而有些市場即使低價股不少，極端漲跌卻非常少見。
從統計結果來看，可以用三個不同角度來看市場結構。
1 最容易出現 100% 漲幅的市場
在跨市場資料中，最容易出現 100% 以上漲幅 的市場通常具有兩個特徵：
- 大量低價股
- 較粗的 tick size
在這樣的市場中，只要價格夠低，單次價格跳動就可能造成非常大的百分比變化。
從資料觀察來看，這類市場通常包括：
澳洲（ASX）
加拿大（TSX / TSXV）
在這些市場中，許多股票長期處於：
- 0.05
- 0.03
- 0.01
甚至更低的價格區間。
在這種價格結構下：
一次最小跳動就可能是 50%、100% 甚至更高。
因此某些市場看起來經常出現「暴漲股」，
其實很多時候只是 價格結構與 tick size 共同造成的結果。
2 低價股密度最高的市場
另一個值得注意的問題是：
哪個市場的低價股最多？
從多國資料觀察，低價股密度較高的市場通常包括：
澳洲（ASX）
加拿大（TSX / TSXV）
英國（LSE）
這些市場的一個共同特徵是：
- 上市門檻較低
- 存在大量小型公司
- 股票價格可以長期維持在極低區間
在這些市場中，可以看到很多股票價格落在：
- 0.05
- 0.03
- 0.01
- 甚至 0.003
這些股票有時候會長時間停留在低價區。
因此在這些市場中，低價股往往不是少數，而是整體市場的重要組成部分。
3 Tick Distortion 最嚴重的市場
Tick distortion 指的是：
最小跳動單位占股價比例過高
當股票價格過低，而 tick size 又沒有相應縮小時，就會產生這種現象。
在極端情況下：
| 股價 | tick size | 單次跳動 |
|--------|-----------|----------|
| 0.1 | 0.01 | 10% |
| 0.02 | 0.01 | 50% |
| 0.01 | 0.01 | 100% |
當 tick distortion 非常嚴重時：
一次最小跳動就可能產生巨大的百分比變動。
從資料觀察，tick distortion 較明顯的市場通常包括：
澳洲
加拿大
英國部分小型股
在這些市場中，極端案例甚至可能出現：
- one tick = 200%
- one tick = 500%
- 甚至更高。
為什麼這些市場會看起來特別「瘋狂」？
當一個市場同時具備以下條件時，就容易出現大量極端漲跌：
1️⃣ 大量低價股
2️⃣ tick size 與價格比例過大 3️⃣ 市場流動性較低
這三個因素結合時，就可能出現：
- 50% 漲幅
- 100% 漲幅
- 極端日內振幅
這些數據看起來非常戲劇化，但很多時候只是：
市場結構造成的百分比放大效應。
一個值得注意的對照：亞洲市場
相較之下，一些亞洲市場呈現出完全不同的特徵，例如：
- 日本
- 韓國
- 台灣
這些市場通常具有：
- 較細緻的 tick size 制度
- 較高的流動性
- 較少極端低價股
因此在這些市場中，即使存在低價股，
「一跳就 50%」或「一跳就 100%」的情況仍然相對少見。
這也說明：
市場制度本身對統計結果具有非常大的影響。
結論
不同股票市場的結構差異，會直接影響極端漲跌的統計結果。
有些市場看起來每天都有大量暴漲股票，但這並不一定代表市場更活躍或更投機。
在許多情況下，這只是：
- 低價股比例
- tick size 設計
- 市場流動性
共同作用的結果。
因此，在進行跨市場比較或統計分析時，將低價股單獨處理，往往能更清楚看見市場真正的價格結構。
Extended Research: Which Markets Have the Most Low-Price Stocks?
After compiling cross-market data from 2020–2025, an interesting question naturally emerges:
Which stock markets contain the highest concentration of low-price stocks?
The proportion of low-price stocks varies significantly across markets.
In some markets they represent only a small minority, while in others they may form a substantial part of the market structure.
Based on cross-market observations, the markets with the highest concentration of low-price stocks tend to include:
1️⃣ Australia (ASX)
2️⃣ Canada (TSX / TSXV)
3️⃣ United Kingdom (LSE)
These markets share several structural characteristics:
- A large number of very low-priced securities
- Listing frameworks that allow relatively small companies to enter the market
- Stocks that can remain at extremely low price levels for extended periods
In some cases, prices frequently appear around:
- 0.05
- 0.03
- 0.01
- even 0.003
Under such conditions, low-price stocks are no longer just fringe securities —
they become a structural component of the market itself.
In contrast, several Asian markets tend to have noticeably fewer extremely low-priced stocks, including:
- Japan
- South Korea
- Taiwan
In these markets, listing standards and tick-size structures make ultra-low price levels less common.
Why Do Some Markets Appear to Have So Many 50% Movers?
Many investors notice a curious phenomenon:
Some markets appear to produce large numbers of +50% or even +100% movers every day.
At first glance, this may suggest extreme speculation or volatility.
However, in many cases this pattern is simply the result of market microstructure.
The key mechanism is:
Very low prices combined with fixed tick sizes.
When stock prices become extremely small, the minimum price increment can represent a large percentage of the stock price.
For example:
| Price | Tick Size | Single Tick Move |
|------|-----------|------------------|
| 100 | 0.1 | 0.1% |
| 10 | 0.01 | 0.1% |
| 1 | 0.01 | 1% |
| 0.1 | 0.01 | 10% |
| 0.02 | 0.01 | 50% |
| 0.01 | 0.01 | 100% |
In the last cases, a single tick can produce a 50% or even 100% move.
As a result, markets with many low-price stocks can appear to generate large numbers of “explosive gainers”, even when the underlying price movement is mechanically small.
Do Stocks That Move 100% in One Tick Really Exist?
The answer is:
Yes — and they are not as rare as many investors might expect.
In extremely low-priced securities, such as those trading around:
- 0.01
- 0.005
- 0.002
if the minimum price increment remains 0.01, then a single price tick may generate:
- 100%
- 200%
- or even larger percentage changes.
These situations are not merely theoretical — they appear in real market data.
The Most Extreme Market Cases
When examining multi-year data across different markets, several types of extreme cases appear repeatedly.
Below are some typical examples.
Case 1: One Tick = 2000%
In extremely low-priced securities, scenarios such as the following can occur:
Price: 0.0005
Tick size: 0.01
This implies a single-tick percentage move of approximately:
2000%
While rare, situations like this do exist in certain markets.
Case 2: Intraday Range Above 500%
In thinly traded low-price stocks, intraday volatility can sometimes appear extreme.
For example:
Opening price: 0.02
Intraday high: 0.12
This produces an intraday range of 500%.
Such moves are not always driven by fundamental changes in the company.
They may instead reflect:
- low liquidity
- discontinuous trading
- large tick-size effects
Case 3: Daily Returns Above 1000%
At very low price levels, some securities may experience extraordinary percentage gains.
Example:
Previous close: 0.001
Current close: 0.01
This represents a daily return of roughly:
900%
or even higher.
These types of events occasionally occur in markets with large populations of micro-priced stocks.
Why These Examples Matter
When market statistics rely purely on percentage returns, a common phenomenon emerges:
Extreme-move rankings become dominated by low-price stocks.
In such cases, the ranking reflects not necessarily the most meaningful market movements, but rather a combination of:
- low price levels
- tick-size structures
- thin liquidity
For this reason, separating low-price stocks from broader market statistics often leads to cleaner and more meaningful cross-market comparisons.
An Interesting Observation
The interaction between low-price stock density and tick-size design creates very different market characteristics.
Some markets contain many low-price stocks but have fine tick-size structures, which limits extreme percentage movements.
Other markets combine:
- large numbers of low-price stocks
- relatively coarse tick sizes
In those environments, it becomes much easier to observe:
- 50% daily moves
- 100% moves
- extremely large intraday ranges
These structural differences explain why extreme-move rankings can look dramatically different across global markets.
The Three “Wildest” Stock Markets
Looking at cross-market statistics from several perspectives reveals an interesting pattern.
Different markets stand out for different structural reasons.
1️⃣ Markets Most Likely to Produce 100% Moves
Markets where 100% daily moves are more frequently observed typically share two characteristics:
- many low-price stocks
- relatively large tick sizes relative to price
Examples include:
Australia (ASX)
Canada (TSX / TSXV)
In these markets, many stocks trade for extended periods around:
- 0.05
- 0.03
- 0.01
Under these conditions, a single price tick can easily represent 50%, 100%, or more.
2️⃣ Markets With the Highest Density of Low-Price Stocks
From cross-market observations, the markets with the greatest number of low-price stocks often include:
Australia (ASX)
Canada (TSX / TSXV)
United Kingdom (LSE)
Common structural features include:
- lower listing barriers
- a large number of small companies
- securities trading for extremely small nominal prices
In such environments, low-price stocks are not rare anomalies but rather a major component of the market ecosystem.
3️⃣ Markets With the Most Severe Tick Distortion
Tick distortion occurs when the minimum price increment represents a large fraction of the stock price.
For example:
| Price | Tick Size | Single Tick Move |
|------|-----------|------------------|
| 100 | 0.1 | 0.1% |
| 10 | 0.01 | 0.1% |
| 1 | 0.01 | 1% |
| 0.1 | 0.01 | 10% |
| 0.02 | 0.01 | 50% |
| 0.01 | 0.01 | 100% |
Markets where this effect is more pronounced often include:
Australia
Canada
certain segments of the UK small-cap market
In extreme cases, a single tick may represent:
- 200%
- 500%
- or even more.
Why Some Markets Appear “Crazy”
A market tends to generate frequent extreme percentage moves when three conditions are present:
1️⃣ Large populations of low-price stocks
2️⃣ Tick sizes that are large relative to price 3️⃣ Thin liquidity
When these factors combine, it becomes much easier to observe:
- 50% daily moves
- 100% moves
- extreme intraday volatility
These dramatic numbers often reflect market microstructure, rather than fundamental economic activity.
A Useful Comparison: Asian Markets
Several Asian markets show a contrasting structure, including:
- Japan
- South Korea
- Taiwan
These markets typically feature:
- finer tick-size systems
- higher liquidity
- fewer extremely low-price stocks
As a result, even when low-price stocks exist, situations where a single tick equals 50% or 100% are far less common.
This highlights an important point:
Market design itself strongly influences statistical outcomes.
Conclusion
Stock markets differ widely in their structural characteristics, and those differences directly influence the frequency of extreme percentage moves.
Some markets appear to produce large numbers of “explosive gainers” every day, but this does not necessarily indicate higher speculation or stronger momentum.
In many cases, the phenomenon is simply the result of:
- the proportion of low-price stocks
- tick-size structures
- liquidity conditions
Understanding these structural effects makes it easier to interpret market statistics and perform more meaningful cross-market comparisons.
