What the ETF Just Happened?
by Corey Hoffstein, Newfound Research
Yesterday morning's trade prints weren't pretty in ETF land. Â Here's a few select favorites:
PowerShares S&P 500 BuyWrite Portfolio (PBP) â Halted at 9:30:46, 9:36:16, 9:42:16, 9:49:29, 9:55:16, and 10:03:35
iShares US Preferred Stock (PFF) â Halted at 9:30:45
Guggenheim S&P 500 Equal Weight (RSP) â Halted at 9:30:25, 9:36:15, 9:42:15, 9:48:15, 9:54:34, 10:00:15, 10:06:15, 10:12:15, 10:18:16, and 10:24:15
iShares MSCI USA Minimum Volatility ETF (USMV) â Halted at 9:30:56, 9:36:15, 9:42:15, 9:49:08, 9:56:08, 10:02:50, 10:08:55, and 10:14:39
Just to be clear here ... some of these ETFs were halted within a minute of the market open.
What happened?  A mixture between people loading up with market orders at the open and a bunch of halts.
These halts are generally at the discretion of the exchange â not the ETF provider â and are called "volatility trading pauses." Â The idea is to give market participants some time to digest what is going on, reflect, and ask the man in the mirror: "do I really want to hit that sell button?"
This wasn't limited to any one ETF sponsor â but occurred across a whole bunch of them.
My takeaways?
Market Orders + Open = Disaster
Market orders at the open is a recipe for disaster. Â Please don't ever, ever, ever do it. Â You don't want to be the person who got that -25% print because liquidity was so thin.
With ETFs, check iNAV
Your brokerage account won't always reflect reality. Â When you log in and see your account down 15% because a bunch of ETFs you own have horrendous prints, you have to take a deep breath and look at iNAV.
iNAV â or intraday net asset value â tells you what the underlying basket the ETF holds is worth.
You can get it by going to Yahoo! Finance  and adding "^" in front of the ticker and "-IV".  For example, to get the iNAV of PFF, we'd enter "^PFF-IV".  Once we see that price has totally dislocated from iNAV, we need to ask ourselves: are the underlying liquid or illiquid?
With the Greece situation â with markets closed â the GREK ETF provided price discovery. Â This morning, however, stocks were trading just fine â it was the ETF that was broken.
Markets are Totally Irrational
If market participants were rational, we wouldn't need halts.  Let me re-phrase that: if market participants were rational, halts wouldn't be effective.  The fact that halts exist and work should tell us all we need to know.
Humans will be human...
