The JSE has apologised for the distribution of inaccurate foreign trading data and has instituted a full review of the checks and balances to ensure that the distribution of erroneous data does not happen again.
Nicky Newton-King, CEO of the JSE, on Monday told Moneyweb that it is important for JSE to “to take accountability fast, to apologise fast and to get the right statistics out there.
This follows a JSE statement, issued late on Sunday, revealing that JSE data relating to foreign trading since May were incorrect. The corrected data stated that foreigners were net sellers of more than R35 billion of South African equities since May.
This is a significant reversal of previous data released earlier that stated that foreigners were the net buyers of nearly R100 billion over the same period. This represents a swing of nearly R130 billion.
Newton-King said that a “glitch” in the programme that calculates the JSE statistics caused the error. “It is not our programme that captures our transactional data, but only the programme that calculates our statistics.”
Checks and balances
She said once the problem was brought to the JSE’s attention, “our immediate attention was to correct the error and to get the correct statistics out for the affected period. What we are doing now is to make sure all of our processes for the production of our data are reviewed and to make sure that we put in whatever checks and balances might be needed going forward to ensure that we minimise the chance that it may happen again.”
Newton-King appreciates the magnitude of the corrected data, as it represents a R130 billion swing in foreign ownership. “We do have significant checks and balances but for whatever reason they were not sufficient in this particular case. We are now focusing on why [that is]; what additionally needs to be done. Unfortunately, computers are programmed by people and that is why we have to take accountability and why we have to apologise now and fully. We will consider what additional checks and balances need to be put in place going forward.”
She also said, following the publication of the correct stats, the JSE will now investigate why it took so long to realise there was a problem with the data. “I can’t give you a full answer (on why it took eight weeks) until we have completed that investigation, but clearly that is something we have to answer.”
The inaccurate data not only affected the cumulative foreign trading data, but also flowed through to the trading of shares in individual companies. Newton-King confirmed however that the correct data was sent through to data providers such as Bloomberg early on Monday morning.
Influence on investment decisions
Amelia Morgenrood, a portfolio manager at PSG, said in response that the misleading data is extremely disconcerting, as it influenced investment decisions. “I interpreted the inflows as a sign of great optimism towards the South African market, due to foreigners piling into local equities. It did create a false confidence and the new data clearly paints a totally different picture of the reality.”
Newton-King is however doubtful that investors would have based trading decisions on this data as it was distributed to a relatively small audience. “I am not sure that people would have traded on this specific data, as a relatively small sector of people actually get the data, but the index for the period has performed reasonably well relative to other emerging markets. But if people believe they want to talk to us in that regard, they can get hold of us through the normal channels.”
No concerns about other data
It seems as if the foreign ownership data was the only set of data that was corrected. Newton King said the JSE is not concerned about any other data sets. “We produce an enormous amount of data. This is an opportune moment to make sure that there is nothing in any of the other datasets that should cause us concern. We don’t have any concern as we speak now, but we are doing a full review.”
