London Silver Fixing Limited in August will end its function as daily price setter of silver for bulk consumers. Sica Wealth Management chief investment officer Jeffrey Sica tells TheStreet's Joe Deaux that the end of the so-called silver fix won't affect retail investors. The banks behind the process are getting out of the business, which would leave large consumers to buy in bulk based on spot prices. Sica says this is probably a good move by the banks, and Sica dives into other so-called dark pools that investors should be aware of. The silver fix ends Aug. 14.
