```FOR EXAMPLE, below you see both "Close" and "RawClose" prices varying
randomly within just TWELVE seconds.

This is Sunday, and these are mutual funds. They don't trade on Sunday,
and they have only one price per business day.

Hence, all the differences in the last three outputs should be zero.

s1 = {#, FinancialData[#, "Close"], FinancialData[#, "RawClose"]} & /@
