Asia Pacific shares

The Asia Pacific equity venues open first and close before Europe has finished its morning, which makes them the region that prices the day's first reaction to anything that happened overnight in the United States. They are also the region where the assumptions carried over from western markets break most often. Several venues stop for lunch. Several bound how far a share may move in a day. Several require orders in fixed multiples rather than in single shares. Ownership is more concentrated. None of this is exotic locally, and all of it changes the shape of a price series.

The venues, and what each one lists 

Tokyo is the largest of them, and carries the Japanese industrial, electronics and financial groups: Toyota Motor Corp., Sony Group Corp., Keyence Corp., Mitsubishi UFJ Financial, Nippon Telegraph and Telephone, SoftBank Group. Hong Kong is the venue through which a great deal of Chinese corporate exposure is accessed by non domestic participants: Tencent Holdings, Alibaba Group, Meituan, AIA Group, China Construction Bank. Seoul carries Samsung Electronics and SK Hynix, and Taipei carries TSMC, which between them account for a very large proportion of global semiconductor manufacture.

India's national exchange carries Reliance Industries, Tata Consultancy Services, Infosys Ltd. and HDFC Bank, in a market with an unusually large and active domestic retail participation. Australia carries the mining and banking complex: BHP Group, Fortescue Ltd., Commonwealth Bank, CSL Ltd. The Australian market is the earliest major venue to open each day and is closely watched for that reason, and its largest constituents are direct expressions of iron ore, coal and base metal demand.

Sessions, and the midday break 

Tokyo and Hong Kong both split the day into a morning and an afternoon session with a break between them, and each session has its own opening and closing procedure. The break is not a technicality. Orders accumulate across it, news arrives during it, and the afternoon session opens on a fresh auction that can strike well away from the morning's last print. Seoul, Taipei, Mumbai and Sydney run continuously, and Sydney and Mumbai both operate a closing auction that sets the official close.

For a reader in the Gulf, the entire region trades in the local early morning, and the practical consequence is that Asian sessions open and close before most Gulf working days begin. A holding carried through the region's session is carried across a window in which the price is live and moving, and the Asian close sits several hours before the European open.

Price limits, board lots and halts 

Several venues in the region bound how far a single share may move in one day. Japan applies a daily price limit expressed as an absolute amount that widens with the share's price level, and a share that reaches its limit stops trading at that price with orders queued on one side. Korea, Taiwan and India apply percentage bands, with India additionally operating instrument specific circuit filters. The effect is that a very large piece of news can take more than one session to be fully expressed in the price, because the venue rations how much of it may appear per day.

Hong Kong and Tokyo both use board lots: the exchange defines the minimum tradable quantity for each listing, and orders in the continuous book are placed in multiples of it. A CFD written on the share is defined by the broker's own contract specification and need not follow the board lot, but the underlying liquidity it references does, which is one reason quoted depth in a high priced Hong Kong listing behaves differently from a similarly sized western one.

Ownership, float and what it does to the tape 

State holdings, founding family holdings, cross shareholdings between listed companies and strategic corporate stakes are all more common in the region than in the United States. The consequence is a free float that can be a small fraction of the market capitalisation, and a float adjusted index weight far below what the headline size of the company would suggest. A share with a small float trades in a thinner book, so the same order moves it further, and its price series carries a higher proportion of gaps and sharp single prints.

Currency is the other structural feature. Each venue quotes in its own currency, and those currencies behave very differently: some float freely, some are managed against a reference, and some are subject to capital account restrictions that limit who may hold them. A contract on an Asian share carries the price move in the local currency and a conversion when the result is booked, and the two are not independent, because the same macroeconomic event frequently moves both.

What reaches a contract written on one 

A CFD on an Asia Pacific listing references the venue's published price, in the venue's currency, and is dealable while the venue is dealing, which includes stopping across a midday break where the venue has one. It settles the difference in cash on a stated number of shares, with no delivery and no register entry.

The regional mechanics reach it directly. A price limit or a trading halt in the underlying removes the reference price, so the contract cannot be dealt at a price the underlying is not making. A midday break creates a second gap risk inside a single day. National holidays, several of which run for multiple consecutive days with no equivalent elsewhere, close the reference market entirely while other regions carry on generating news. Dividend and corporate action treatment follows the broker's published policy, and the instrument specification is the document that states which of these applies to a given listing.
