對手挑戰勢洶湧，香港交易須加時？ 20251126

 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。

Cambodia - a relative winner amidst Thai clashes & US tariffs

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...

Border clash and trade - Cambodia on the upper hand

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

Article 3: trade dropped sharply in August 2025, with imports down 29.1% ...and exports down 36.2% ...though Cambodia’s overall trade grew 15.5% to $42.15 billion, driven by markets like the US and Vietnam

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.

Growth elsewhere may offset much of the loss?

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)

Tariff - best of the lot!

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:

latest GDP forecast (Aug 2025, see here)

Senior ministers: young and highly educated

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:

Noteworthy is how the average age being only 55 years old, with 60% of the ministers younger than 60. Meanwhile 57% of the ministers have university degrees, from Harvard to NUS, from MIT to Wharton! The PM, Hun Manet, is even a West Point graduate...

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?

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.

Should HKEX extend trading hours to stay competitive?

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.

讀張維迎專訪有感：干預經濟屬「致命的自負」20250902

近日閒來閱讀，碰上一篇值得推薦的文章，視頻如下，亦附全文於尾：

   

北大張維迎﹕干預經濟屬「致命的自負」｜信報月刊專訪 

近年本港越見奉行大政府經濟政策，正是張公所批評的行政干預思維。此一現象在當今經濟疲弱之勢下，尤為顯著，當就業人口在2019移民潮開始後大幅下挫，再遇北上消費，通關後外遊等因素，令本港就業境況「見波幅，無升幅」已達四年之期： 

 

在此緊縮環境下，卻見公營部門編制屢創新高（見【橙線】），直追本港經濟最高增值板塊（金融是也；同時可見金融線亦在漸行漸低，勢頭不妙，見【紅線】）：

再以絕對值比較，原來公共行政／社會服務類別搖搖領先於2019-2025年間之增幅榜，大幅抽高4.1%；在人口和就業人數皆下跌的環境下，是否有些膨脹的感覺？儘管公務員編制微降1.4%，但相對於整體就業人口下跌6.7%的大局下，於滿街吉舖的今天（零售／飲食業人手在同時間大縮22%之巨！），似乎政府仍然瘦身未竟，須要更加努力：

 行文至此，再翻出數篇以前拙作，皆與下文理念相近，以饗讀者：

【信報月刊】干預經濟屬「致命的自負」—— 北大教授張維迎：相信企業家和市場自有出路 

 【本刊記者李俊杰】回顧歷史，人類的狂妄與自負往往帶來災難。40多年的研究讓著名經濟學家張維迎堅信，處理宏觀經濟，唯有收起致命的自負，讓企業家在市場當中試錯與成長，才能切實帶來社會創辦與進步，讓哪怕是普通百姓都能受惠，這也是他為當今中國經濟開出的藥方。今年6月初，張維迎親臨香港恒生大學接受榮譽博士學位，記者藉此機會跟他進行了一場關於中國經濟前景的訪談。

北京大學教授張維迎是中國經濟學界的市場派領軍人物，多年來著作甚豐，以思考邏輯綿密、言談豪氣干雲見稱，名場面不勝枚舉。

2016年在北京大學朗潤園跟主張政府強力介入市場的「經濟國師」林毅夫教授激辯；2017年於北京大學國家發展研究院畢業禮以《自由是一種責任》為題致詞演講；疫情期間的公開演講，也一針見血地指出企業家信心不足緣於體制及法治，全都讓人印象深刻。

市場經濟、自由、法治、企業家精神──這是他1984年在中國經濟學界嶄露頭角以來，一直主張而且捍衞的核心思想。不論是當年改革開放大潮流，還是現時國進民退苗頭漸現，這位奧地利學派經濟學家始終忠於自我認知及思考。
「無論你是官員還是科學家，也不論你有多聰明，知識都非常有限。你不要那麼狂妄，不要覺得自己無所不知。我們很渺小，所以才要市場，讓大家選擇。」時刻保持自省自覺的張維迎觀察到，過去十餘年，一種跟承認無知截然相反的自負在中國強化得比較厲害，「特別是我們加入世貿後，取得巨大經濟進步，財富增加許多，很多人回答『我們為什麼發展得這麼快？』時，傾向歸因於中國的特殊性，例如，政府較多控制經濟等等。」

致命的自負

「尤其受過一定程度教育的人，總覺得自己全盤理解社會運作，以為最優決策是一道數學公式，有標準答案，可以計算出來，『按照我的方式去做，社會就會變好』，但真實世界不是這樣的。」

張維迎借用奧地利學派宗師海耶克（Friedrich Hayek）的作品名稱《致命的自負（The Fatal Conceit）》來形容這種心態，「計劃經濟本身就是致命的自負」。他以曾被他形容為「穿着馬甲的計劃經濟」的產業政策來解釋：「產業政策利用國家政策和資金，扶持特定行業發展，當中意味着，一些人能夠看準未來要怎麼做。」

「產業政策所表現出來的集中化（投資）像中國人押寶一樣。賭注放在同一點，風險很大。近年最典型的是就是電動車和光伏產業，兩者現時均有巨大產能過剩，這很大程度是政府的政策造成。」
