https://www.rthk.hk/tv/dtt31/programme/investmentera_tv/episode/998869對港人而言,投資美股幾乎是證券投資的基本動作。每當有人提到昨夜又開通宵,常聞問曰:「又炒美股呀?」可見美股在港人證券投資的比重何其之高。美國交易所似乎亦欲在亞洲時段吸納亞洲投資者日漸龐大的財富,因而有報謂紐約證券交易所(下稱【紐交所】)正研究延長交易時間(見此),將休市時段縮至僅兩小時(見【圖一】底棒所示):
圖一:紐交所和倫敦交易所俱有延長交易時間的計劃
與此同時,對岸的倫敦交易所(下稱【倫交所】)據報(見此)亦積極研究如何增加交易時數,至更為進取的「全天候」服務(見上圖第二條棒)!
證券市場環球化 交易時段無休止?
隨著資訊流通越趨發達,兼網上交易普及,跨境投資與「隨時入市」的需求必會穩步上升。以下為環球主要交易所在一日24小時內的交易時間分布:
圖二:全球主要股票交易所交易時間的分佈
亞洲交易所:本地為尊
上表【紅色】區域顯示,亞洲大多數交易所仍以服務本地投資者爲主:早上九時後開盤、下午五時前已鳴金收兵,更有個別地域保留長達兩小時的午休時段(黃色區域)。值得留意的是,除澳洲證券交易所與日本交易所較早開市外,大部分亞洲與歐洲主要市場仍具一定重疊時段,有利跨區交易。
歐洲時區:左右逢源,得天獨厚!
上表【綠色】區域所代表的歐洲、中東及非洲時區具有一個天然的優勢:既承接亞洲交易,亦接軌美洲時段!不出所料,德國人的勤奮在法蘭克福交易所交易時段全面反映:彼開市與杜拜同步之餘,更在收市上比倫敦更遲;甚至比美加股市晚兩小時打烊!
第二進取的非杜拜交易所莫屬:雖比倫敦時區早四小時,卻刻意早其一小時開市、兼在倫交所收市一小時後方歇業,積極搶佔時段優勢。歐洲的地理位置令該區交易所能在亞洲市場收盤前承接市勢,並無縫交棒予美國,發揮連貫市場流動的重要橋樑作用。理解此結構後,不難明白倫敦交易所倡議延長交易時段【淺綠區域】的原因——盡覽全日所有時區的交易量。
美國市場:最須延長交易時段
美國股市獨霸全球,其兩大交易所包攬達49萬億美元市值的股票,超越全球其他主要交易所的總和(約45萬億美元);總成交額方面更達50萬億美元,較其他市場的合計值高出一截(以上皆為2023年數據)。在這樣的基礎上,美國若延長交易時間,帶來的實際效益可能比對手所能達到的更為可觀。
延長交易時數是否確實有用?
為解答以上疑問,筆者將成交量對市值比例與交易時間長短作對比,結果如下:
圖三:成交量/市值比對交易時數
乍看下,似乎兩者間毫無關連:
一)美國兩大交易所(紐交所與納斯達克,上圖被【藍線】貫穿)雖交易時段偏短,但成交量與市值比卻居全球開放市場之首;
二)反觀中國的上交所與深交所,雖屬全球交易日最短市場之一,成交頻率卻異常高。
除了資本管制鎖住流動性外,筆者相信中國市場的極高交易頻率可能歸根於國內有限的投資選擇/渠道,及甚高的散戶參與比例,如下圖所示:
圖四:成交量/市值比與散戶參與程度似有關連
顯而易見,散戶持股佔約八成的內地交易所,似乎符合「高散戶比例=快成交週轉」此一假設。若剔除內地交易所,其他市場的成交流轉率似乎與每日交易時數關連不大──雖然多數交易所都在5-7小時區間內,但流轉率卻分散甚廣,由十多至百多個百分點都有:
圖五:成交量/市值比對交易時數(摒除上交所+深交所)
值得留意的是倫敦證交所:儘管交易時段頗長,卻在效率表現上大大落後,顯示或有其他結構上因素,如估值偏低、監管繁重、令其市場吸引力不足?可見,延長交易時段只是資本市場環球競爭下其中一項策略,而非萬應靈丹。
香港:須鬆綁升級延時
整體而言,本港應何去何從?筆者認為,港交所可考慮三大方向增加吸引力:
一)放鬆管制,及減輕證監會日趨嚴苛的干預應可吸引更多企業上市,並提高市場活躍度;
二)內地政策支援,如在地緣政治風險升溫下協助中資企業回流香港上市,此趨勢料可延續多年;
三)檢視並延長交易時段,甚至包括取消午餐休息;在各大競爭對手紛紛伸延交易時間的今天,此一改變似乎難以避免。
這些改革應可提升港交所競爭力(如:未來ADR的成交量亦回歸本土);當有一天本港股市終於追上美國兩強時,環球投資者必會稱許可隨時隨地交易港股的方便,從此無須半夜爬起床買港股。

Below we reproduce the third of our write ups from recent due diligence trip to Phnom Penh (PP). This issue concerns the politics facing the country, including Cambodia's border conflict with Thailand, as well as the threat of US tariffs at large.
We spent some good time researching these aspects and are happy to report that the bill of health is significantly better than we had feared, and what you may have expected, as well...
Whilst a lot of ink has been spilt on the negative impact of the border clashes, such as:
Article 2: ...conflict is projected to significantly impact Cambodia’s GDP and Thailand’s economy in the short term
In fact, the conclusion is already given in the headline of article 3 above - the important marginal development is Cambodia's enlarging pie with the rest of the world, rather than how it is shrinking with an ageing neighbour...
Cambodia net trade as % of GDP
What is more, Thailand has a massive trade surplus with Cambodia, worth 6% of Cambodia's GDP (red line above), meaning the need to reconcile is much stronger for Thailand than for Cambodia; however, a meaningful amount of this trade may be input components for Cambodia's further export processing.
In fact, looking at some sectors of the economy, you can detect significant increase in activities with other partners (article 4) , and especially so with China (article 5):
Article 4: The Royal Group Phnom Penh Special Economic Zone (PPSEZ) ...attracting new investments from China and Japan and employing over 55,000 workers.
Article 5: ...China bilateral trade reached a record $14.2 billion in the first nine months of 2025, up 27% from the previous year
The China element highlights the geopolitical trend we have been citing as a strong tailwind for Cambodia's industrialisation - the re-shoring of PRC manufacturing capacity to SEA!
As more migrant labourers return home, the momentum for capacity growth domestically also receive a major boost, where new factories will no longer have to compete with other nations for home grown workers working abroad:
Article 1: Border clashes forced 910,000 Cambodian migrant workers to return from Thailand
The flipside of this development is a loss of foreign remittances back home, which hopefully will be short term, and as these migrant workers are absorbed into new industrial zones, a lot of the lost wealth pre-remittance will now be kept in the borders of Cambodia:
Inflow remittances (%GDP)
The super proactivity in trade negotiations, even to the point of nominating President Trump for the Nobel Peace prize, suggests how hands-on the Cambodia administration is, compared to sleepier neighbours, amply illustrated by its lowest new US tariffs compared to other Asian competitors:
As a result, the latest forecast upgraded post-border clashes still sees Cambodia GPD to grow 5% before bouncing back to the 6% handle:
Most people may associate Cambodia with patriarchal sedantry, but a look beneath the hood reveals that the country is ruled by highly educated, young technocrats - below is the full list of cabinet ministers with their age and education:
Shouldn't these credentials give investors far more confidence investing in Cambodia than Thailand or Vietnam or Malaysia - the current top go-to destinations of investor property buying money?

Cambodia’s Growth Outlook Adjusted Downward Amid Border Conflict
Mekong Strategic Capital’s latest forecast anticipates Cambodia’s GDP growth slowing to around 3% in 2025, down from an earlier expectation of around 5%. This revision reflects the multifaceted economic fallout from the conflict, which escalated rapidly to become the region’s most significant economic risk.

Decline In Cambodia’s Imports From Thailand Signals Strained Trade Ties
According to the General Department of Customs and Excise (GDCE) of Cambodia, the total value of Cambodian imports from Thailand in August 2025 fell sharply to approximately $213 million, representing a year-on-year contraction of 29.1% from the $301 million recorded in August 2024. Cambodian exports to Thailand also dropped significantly by 36.2% to only $46 million in the same month, underscoring the mutual impact of deteriorating trade conditions between the two neighboring countries.

Trading US stocks have long been a popular investment avenue for Hong Kong individual punters, and when one says “I’m staying up late tonight” one is often greeted by “To trade the market?”, Obviously the exchange operators in the US are eyeing the potential of tapping the increasingly affluent Asian investors in their own time zones, with the New York Stock Exchange (NYSE) reported to be looking into extending its trading hours (see here), with only 2 hours of rest between sessions (bottom bar below):
|
Figure 1: NYSE and LSE proposals to extend their trading hours |
Not to be outdone
by their peers across the pond, the London Stock Exchange (LSE) is now
also reported (see here) to be studying how they could extend their offering – to an even more
ambitious round-the-clock service (second bar above)!
Global markets
call for 24-hour availability?
With stock investing going global in the age of easy data feeds and
online trading platforms, the need to be able to access your target markets can
only rise. Let us look at the current set up across major exchanges in each
time zone:
|
Figure 2: trading hour distribution of major stock
exchanges around the globe |
Asians – mostly
localised services
Represented by the
red areas above, it is clear that most Asian stock markets cater only to
their local investors, with all of opening after 9am and closing by 5pm local
time. What is more, they are the only markets with long lunch breaks (up to 2
hours, yellow area above).
There is also a
convenient trading overlap with major European exchanges except Australia Stock
Exchange (ASX) and Tokyo Stock Exchange (JPX) which start earlier than the rest
of the pack.
Europeans –
geographically lucky to straddle
In the EMEA
(Europe, Middle East, Africa) time zone (represented by green areas) the
most diligent are the Germans, with Frankfurt Stock Exchange (FRA) boasting the
longest trading hours and basically out-trades every competitor in its region;
what is more, its trading hours also completely envelope the US major bourses
too! This is followed by Dubai Exchange (DFM), which despite being 4 hours
ahead of London, tries to grab business by starting an hour ahead of the London
Stock Exchange (LSE) and closes one hour afterwards.
The favourable
location of Europe allows these exchanges to overlap with Asian exchange at the
start of the day and then again segue into the American exchanges before they
shut up shop, thus serving a crucial bridging function in providing market
continuity over the day.
Now that we have a
basic understanding of the trading hour distributions, it is not hard to see
why LSE is proposing – to extend its own time advantage to cover the entire
world (light green area)!
Americans – biggest
need to extend trading hours
Given how
overwhelmingly dominant the US stock markets are – the two US exchanges are
home to $49trn worth of market capitalisation, more than all the other above
exchanges combined at only $45trn, and value traded totalling $50trn compared
to $48trn for the rest (above all 2023 figures) – there is probably far greater
practical benefit to extending the US trading hours.
What do the numbers say about lengthening trading
hours?
In theory, the longer the trading session, the higher should an
exchange’s volume-to-market-cap ratio be. Below is a plot of all exchanges in
our study:
|
Chart 1: Vol / Mkt Cap vs Hours Traded |
There does not
seem to be any correlation at all it seems:
a)
the
two biggies (NYSE + NASDAQ, marked by a horizontal blue line) top the
volume/market cap metric amongst all open capital account markets, despite
their shorter trading hours;
b)
the
two Chinese exchanges Shenzhen Stock Exchange (SZSE) and Shanghai Stock
Exchange (SSE) have disproportionately high volume relative to their listed
market caps, all while having the shortest trading hours!
Besides capital controls (which trap liquidity), we
also suspect that lack of investment alternatives and high retail participation
are the drivers of such high trading velocity for the Chinese exchanges:
|
Chart 2: Vol / Mkt Cap vs Retail Participation |
The chart above seems to prove our suspicion –
with significantly higher retail stock investing (in the 80%s), the PRC
exchanges corroborate the trend line of higher retail = higher volume/market
cap.
If we take out the
PRC exchanges, then we get a tighter new pattern (Chart 3), where 5 to 7
hours seem to be the norm for most jurisdictions, with a large volume/market cap
spread between the high teens through to over 100%:
|
Chart 3: Vol / Mkt Cap vs Hours Traded (Excluding SSE & SZSE) |
One big disappointment is that of LSE, which despite
having longer trading hours, features badly in its trading efficiency. This
suggests that there are other structural issues at play – could it be low
valuations which put off potential listing candidates, or is it
over-enthusiastic regulation making life difficult for existing candidates?
After all, what this also points to is the fact that stock exchanges are in a
global competitive race for members, and extending trading hours is but one of
many factors that will make or break an exchange’s future prospects.
Hong Kong – extend and upgrade
What does all of these leave HK? We can discern a
number of actions that will help the city:
a) as always deregulation and limiting the over-protective
interference of the SFC will definitely attract more listings and trading
volume;
b) policy help from mainland China certainly helps – including all the redomiciling of PRC listcos to HK given heightened geopolitical risks, a trend we see continuing for a number of years ahead;
c) and of course, longer trading hours, including even
scrapping the lunch break - this is now almost unavoidable given the biggest to competitors are both studying similar strategies, HK should not be left behind.
All of these measures will help prepare for the day
when HKEX’s stature approaches that of the American exchanges, when overseas
traders would appreciate the convenience of trading HK stocks any time they
want, and not having to get out of bed in the middle of the night to do.
