After using the HistoricalChainResolution API to find some RIC constituents, I am coming across equity RICs that have no data in the TRTH EquitySearch endpoint, nor any data on permid.org or QAC's RIC dataset.
Here is a sample of the RICs I cannot find any information on:
'SMQIP.AX','TLSIP.AX','HSBN.AX','IFANA.AX','KLZN.AX','TNZIP.AX','MMUN.AX','AJOXX.AX','SMEXX.AX','VEPN.AX'
If old RICs are or were being deleted, why is this and why do they still appear in the TRTH HistoricalChainResolution endpoint?
