1. Local Shares: Both local and foreign investors can trade local shares, but foreign investors are not entitled to dividends and voting rights.
2. Foreign shares (stock symbols with suffix "–F"):  SET has established a foreign trading board where foreign investors can register their investment holdings and be eligible for the same benefits as local investors.  Foreign investors are entitled to dividends, rights issues & warrants and voting rights. Most SET-listed Thai companies have foreign ownership restrictions.  The information on the foreign ownership restrictions in respect to each individual stock is available on SET’s website:  https://www.set.or.th/en/market/get-quote/stock/
3. Non-Voting Depository Receipt (NVDR) (stock symbols with suffix "–R"): SET created Non-Voting Depository Receipts (NVDRs) to stimulate trading activity and to help eliminate barriers of foreign holding limits. NVDRs automatically carry the same prices and financial benefits as their underlying securities; the only difference is that NVDR holders do not have voting rights.  Information on NVDRs is available at: http://www.set.or.th/nvdr/en/faqs/faqs.html. Voting rights is not applicable for NVDR holders.

Note: You may convert "Foreign Shares" to "NVDR Shares" by first converting to "Local Shares" then subsequently to "NVDR". This is done post trade and is subject to commission fees.
