Board Lot System Explained

Minimum shares

Board lot is the “minimum bundle” of shares you can normally buy.

Some items are bought per piece, others by pack. In the PSE, many stocks trade by board lot: the stock price range decides the minimum number of shares and the price movement.

What is tick size?

Tick size is the smallest price movement allowed. Example: if tick is ₱0.05, the next price steps move by five centavos.

Why this matters

Your starting cash depends on stock price × required lot size plus fees. Always compute before placing the order.

Quick example

If a stock is ₱10 and the lot size is 100 shares, one regular lot is about ₱1,000 before fees. If you buy 1,000 shares, compute around ₱10,000 plus charges.
