About Stock Exchange of Thailand.
Stock Exchange of Thailand is the principal cash-equity venue of Thailand. Founded in 1975, it operates under the oversight of Securities and Exchange Commission, Thailand (SEC (Thai)), and its leading benchmarks are SET Index, SET50, SET100. Listing standards are set out in the SET Listing Rules; SEC Act B.E. 2535.

Thailand’s principal equity venue, with index weight in energy, banking and infrastructure. Non-resident holders frequently sit in the NVDR (Non-Voting Depository Receipt) structure, a recurring consideration when a foreign position is pledged.
On SET, a block is crossed on the Big Lot Board away from the continuous order book, with the trade reported into the exchange’s system rather than shown as it prints. The largest, most liquid SET50 and SET100 names — energy, banking, telecoms — absorb size most readily; mai and thin lines are worked more carefully. Where the seller is foreign, whether the stock moves as ordinary shares, foreign-board (F) shares or NVDRs affects both the achievable price and the reporting, and settlement runs T+2.
What qualifies on SET.
SET is an established but selective venue; we weigh eligibility against the stock’s liquidity, free float, and how concentrated the holding is.
For any given SET position, our review looks at: free float and daily traded volume against the size of the transaction; your status (controlling shareholder, director, substantial shareholder) and the disclosure that follows; the issuer’s sector and listing segment; and what the transaction must do (LTV, tenor, currency, recourse, custody).
Framework cited on SET.
The principal regulatory reference on SET is SEC Notification TorJor. 7/2552. How it applies to any single transaction — reporting levels, step thresholds — turns on the underlying rules and national-law overlays, which we map against your contemplated transaction at the structuring stage alongside the counsel you appoint.

What Is a Block Trade, and How Does One Work?
A block trade is the off-market sale of a large line of listed shares at a negotiated price, executed bilaterally and printed under exchange rules to avoid moving the open market.
Read → Block TradesHow Do You Sell a Large Block of Shares Without Moving the Price?
A large block is sold without moving the price by taking it off the open order book — negotiating off-market at an agreed price, often with a liquidity provider taking the risk, and printing under exchange block rules.
Read → DisclosureDo Block Trades Have to Be Disclosed?
Often yes. Once a significant shareholder crosses a market’s substantial-holding threshold, a block sale is generally notifiable to the regulator within a set window, with thresholds varying by jurisdiction.
