Data Darkness

There’s apparently a reality TV show called “Dating in the Dark.”

It must lack the cachet of Survivor or The Bachelor because you don’t hear much about it. The gist is that a number of people of opposite sexes wander around in utter blackness falling in love. You wonder how that’s superior to the displayed market – so to speak.

But in the equity market, dating in the dark is a big deal. I’m talking about how stock orders find each other. Take Coca-Cola (KO), which reported yesterday. From July 8-12, according to Fidessa’s Fragulator, 25.6% of trades occurred on KO’s listing exchange, the NYSE. But 29.4% were on the FINRA NYSE tape, a reporting facility for trades between brokers rather than on exchanges.

The remaining 44% of KO’s trading mostly met in displayed markets at the Nasdaq, BATS and Direct Edge, and the NYSE’s derivatives-centric platform called NYSE Arca, formerly the ECN Archipelago.

Why does this matter to you, IR professionals? It’s important to understand what’s happening. This is the market you manage – the equity market for your shares.

So, FINRA – the Financial Industry Regulatory Authority – is trying to address concerns that a large amount of stock-dating in the dark is bad for markets. That volume of KO’s on the FINRA NYSE tape? It’s “dark pool” trading, where buyers and sellers meet secretly and anonymously through brokers acting like millionaire matchmakers.

Last week FINRA sent a proposal to its members that would create new reporting rules for dark pools. If adopted, alternative trading systems, or facilities where the principal function is matching trades but the regulatory structure is one for broker-dealers rather than the regime exchanges operate under, would report their trades to FINRA on a delayed basis using a unique market-participant identifier. That way, FINRA would know what trades and volume occurred in each facility to better identify market-manipulation. (more…)
