An odd lot is fewer than one lot (1,000 shares). It lets you trade from a few shares with less money, with its own sessions and rules.

What an odd lot is

In Taiwan one lot is 1,000 shares. An odd lot is fewer than a lot, from 1 to 999 shares. At 100 TWD a share, a lot costs 100,000 TWD, while 10 odd-lot shares cost 1,000 TWD.

How odd lots trade

There are currently two sessions (follow the exchange’s announcements for exact times):

• Intraday odd lots: during the normal session, odd lots can be ordered and matched too.
• After-hours odd lots: a separate period after the close with a call-style match.

Ordering resembles ordinary stocks but you choose odd lots in the broker’s screen. There is a limit on shares per order and usually only limit orders are allowed; details follow the broker and the exchange.

Things to note

• Brokerage fees: brokers often set a minimum fee, which can take a larger share of a small trade.
• Transaction tax: selling shares attracts securities transaction tax as set by regulation.
• Execution and spread: odd lots may be harder to fill than round lots, or fill away from your expected price.
• Dividends: odd lots also receive dividends, in proportion to shares held.

How to think about them

Odd lots let people with limited funds reach stocks and diversify, but the risk is the same as for round lots: when the price falls you can still lose money.
