Can you buy single shares of Xiaomi or do you need to buy 200 shares at a time?

It all depends on where you buy the Xiaomi stock.

Hong Kong Stock Exchange (1810.HK)

• On the HKEX, stocks trade in “board lots” (minimum trading units).
• For Xiaomi (1810.HK) the board lot is 200 shares.
• That means if you buy directly in Hong Kong, you have to buy at least 200 shares (or multiples of 200).
• Example: If Xiaomi trades at HK$15, the minimum investment is HK$3,000 (~US$380).

U.S. OTC Market (XIACF, XIACY)

• In the U.S. OTC market, you can buy single shares (no board lot restriction).
• So if you’re using a U.S. or international broker that gives access to OTC, you can buy 1 share, 10 shares, 37 shares — whatever you like.
