ETF Liquidity the Real Victim of Thursday's Sell-Off

Market liquidity was tested on Thursday. It failed. The blame game is now in full motion, with many analysts pointing to an NYSE circuit-breaker mechanism that seems to have backfired .

The carnage was bad for stocks, but even worse for ETFs and ETNs. Much is being made about the Accenture ( ACN ) trade that took place at a penny . However, of the 971 ETFs and ETNs with trading activity on May 6, twenty-two traded for a penny or less and 164 traded for less than a dollar.

By my count, 167 ETFs and ETNs experienced intraday drawdowns in excess of -90%. That translates to more than 17% of those that traded. The NASDAQ and NYSE ARCA (the electronic trading arm of the NYSE) said they would cancel many trades. The official notice from NASDAQ reads:


We have coordinated a process among U.S. Exchanges and therefore, pursuant to NASDAQ Rule 11890(b), NASDAQ, on its own motion, will cancel all trades executed between 14:40:00 and 15:00:00 greater than or less than 60% away from the consolidated last print in that security at 14:40:00 or immediately prior.

I do not have any easy way of determining all the ETF prices immediately prior to the panic, so the following analysis is based on moves from the prior day's closing prices.

  • 183 ETPs (18.8%) had trades in excess of -60%
  • 25 ETPs (2.6%) had trades in excess of +60%
  • 208 ETPs (21.4%) are therefore subject to having some of their trades cancelled
  • 149 ETPs (15.3%) had trades from -15% to -60% which will not be cancelled
  • 67 ETPs (0.7%) had trades from +15% to +60% which will not be cancelled
  • 216 ETPs (22.2%) with extreme trades from +/-15% to +/60% had none of their trades cancelled

I think it is reasonable to assume that most of the ETPs that traded more than 60% away from the prior close also had trades that were in the 15% to 60% range. Based on that assumption: Approximately 424 ETPs (43.7%) had extreme trades from +/-15% to +/60% that will not be cancelled. There were participants on each side of those trades. Some are happy, some are not so happy.

Most markets were already down more than 5% from their recent peaks prior to Thursday's action. Therefore, nearly every trailing stop on long unleveraged equity ETFs was triggered. More regulation: coming soon to a stock exchange near you.

Every month I harp on ETF liquidity concerns, while others say there is nothing to worry about. Ask the owners of the 424 ETPs mentioned above what they think.
