Material nonpublic information may never be used. Never!
Mosaic theory deals with a combination of public information (material or not) and nonmaterial nonpublic information. It’s always OK to use nonmaterial nonpublic information. Always.
The key distinction here is between material and non-material non-public information.
You can use non-material non-public information, you can’t use material non-public information.
It’s covered in the Standards of Practice Handbook, but generally speaking non-public information is material if its release the public could reasonably be expected to move the assets price or a reasonable investor would want to know it before buying/selling/holding.
If you do a lot of ethics questions, when you get a question on mosaic theory and whether or not non-public information is material I’ve found it becomes almost second nature to decide, it just takes practice.
I didn’t know about the difference between material and non-material nonpublic information.
Thanks to both! I’ll pay attention to this the next time I come across a question like this
