Buying Hong Kong stocks: lot sizes vary by ticker, and stamp duty hits both sides Buying Hong Kong stocks: lot sizes vary by ticker, and stamp duty hits both sides
Hong Kong is often the first Asian market people outside the region try, partly because most brokers offer it and partly because the well-known names are familiar. Two mechanics catch newcomers, and neither is obvious from the order screen.
**Lot size is set per stock**
Hong Kong uses board lots, a minimum trading unit. So far this resembles Japan, which uses 単元株. The critical difference is that Japan standardised every listing at 100 shares in 2018. Hong Kong never did.
Board lots vary by ticker. Some trade in units of 100, others 500, 1,000, or 2,000. This means share price alone tells you almost nothing about the minimum ticket. A stock quoted at a low price with a 2,000-share lot requires a larger outlay than a higher-priced stock with a 100-share lot.
Check the board lot before deciding anything. Brokers display it in the instrument details, and HKEX publishes it.
Odd lots, meaning quantities below the board lot, trade in a separate mechanism with thinner liquidity and generally worse pricing. You can end up holding them through corporate actions such as splits or scrip dividends, and disposing of them is awkward. Worth knowing before it happens rather than after.
**Stamp duty applies to purchases as well as sales**
This is the part that surprises people used to markets where government charges fall on the sell side or not at all.
Hong Kong levies stamp duty on stock transfers at 0.1% of consideration, charged to each side of the transaction. Buying costs it. Selling costs it again.
The rate has moved. It was raised to 0.13% in 2021 and reduced back to 0.1% effective 17 November 2023. Older guides and forum posts still quote the higher figure, so check the date on anything you read.
On top of that sit the SFC transaction levy and exchange trading fee, both small, plus your broker's commission. The practical effect is roughly 0.2% in government-related cost for a round trip, before commission. Negligible for a long hold. Meaningful if you trade frequently.
**Two more things worth knowing**
Trading hours run 09:30 to 12:00 and 13:00 to 16:00 local time, with a lunch break, similar in structure to Tokyo. Hong Kong is one hour behind Japan and Korea.
And there is no daily price limit. Unlike Korea's ±30% or Japan's price-band table, Hong Kong does not cap how far a stock can move in a session. If your instincts come from a limit-based market, recalibrate before sizing positions.
