Liquidity problem might drive the etf prices down compare to the actual index. No one guarantees the price will match the actual assets.
To me, having vix in the portfolio is as good as applying a hedge and since it is negatively correlated to risk, it does not add on to overall returns on a risk adjusted basis.
Hmm. Counter argument, and I’m just thinking out loud here: long-VIX is a negative carry position (for anyone who doesn’t believe me, look at the long-term chart of VXX). If you’re trying to reduce your portfolio risk, wouldn’t it be better to just reduce your equity delta and carry more cash?
(Oddly enough, shorting SPX futures these days is a very slightly positive-carry position—because the interest you earn on the implied cash is more than what you’d pay in implied dividends.)
There were probably several computers owned by people (businesses) that noticed that particular problem and swooped in.....This lasted for about fifteen minutes - and in that time, a few ETFs traded 5-10% out of line with their NAVs (I bought some of them!) - but once market-makers started stepping back in, prices converged with their NAVs, and everything was fine by about an hour after the open.
So, three things:
1) It was a huge trading opportunity for people who were actively watching the markets and didn’t panic;
I’ll have to check the latest numbers, but I believe the bulk of long-term U.S. investors’ stock assets are held in mutual funds, not exchange-traded funds. So that’s another reason long-term investors didn’t notice anything.2) Long-term holders didn’t even notice it had happened, because it was over in less than an hour;
Yet another great reason to turn off the Financial Porn Channel.3) The only people who were hurt were people who saw CNBC screaming “OMG ETFs are broken SELL EVERYTHING” and panicked.

How can I purchase Vix through dbs vickers?
Are you referring to the “decaying” of the VIX pricing mover time?

That’s already happened, and the markets were fine. I know ‘cause I was there.
It was August 2015. The futures markets were shaky overnight, and when the markets opened up in the morning, the market-makers started withdrawing their bids and offers because the markets got too volatile.

Thanks Shiny. I think index etf is generally safe. Not sure about other ETFs though
You're right that index ETFs are safe, though I'd go beyond "generally" safe - I think the creation-redemption mechanism means they're pretty much immune to liquidity disruptions, and the fact that the August 2015 disruption was as short as it was (less than an hour) is proof of that.
What sort of "other ETFs" are you concerned about?
Those leveraged etf, vix etf, commodities contract ETFs. Any etf that involves derivatives of sort. They can go burst if black swan event happens.
Even though I have a bullish view of China, and everyone is claiming China is a sleeping dragon.
This trade war had shown that it is the USA who is waking up.
Frankly, during this calm period I'm beginning to miss Trump and all his injected volatility.
