The surge in equity trading volume that has accompanied the recent volatility has been a boon to the dark pool industry. At the top of the pack, many are experiencing record volume, reports Traders.

In the case of Goldman's Sigma X, a recently inked deal that links dark pools operated by Goldman Sachs, Morgan Stanley and UBS has also made a difference. Some discern that a bulge bracket of sorts is emerging in the industry, with mounting barriers to entry. It makes sense that volume will lead to more volume, which will make it harder for other pools to jump into the elite group.
