By opting out of the Stock Yield Enhancement Program, you are choosing not to lend out eligible assets from your Moomoo SG universal account, and you will no longer earn interest returns (if any) from this program.
After applying for opt-out, the eligible assets in your account may still be lent, and you will receive corresponding interest within 1-2 trading days, after which the program will be completely terminated.
If you want to opt out, you can access through: "App > Accounts > Universal Account > More > Stock Yield Program", and request an opt-out in FAQ.
