Can VTSAX accidentally sell all its stock holdings?

Is this possible at all? I have read of various traders making mistakes elsewhere. Was just wondering if it is possible for a fund management trader to accidentally sell all stocks in say the Vanguard Total Stock Market Index fund. How often does this sort of a thing happen? Is this a reason to diversify between different fund providers?

It's less likely than a celestial body impacting the earth. I really suggest you worry about that possibility instead.

The assets of TSM are $917.9 billion. That's billion with a B. I think someone at Vanguard would notice. The market would certainly notice!

Indeed. If Vanguard sold $917.9B of TSM's holdings at once, you wouldn't be safe in any fund.

True, but the point is that the 1 trillion wouldn't go through. Market makers would immediately pull all bids and the market would just disappear. Exchanges would be halted and SEC would come in to ask what the heck happened.

The story of what happened at Knight Capital Group in 2012 is also interesting. Quoting from https://en.wikipedia.org/wiki/Knight_Capital_Group,
On August 1, 2012, Knight Capital caused a major stock market disruption leading to a large trading loss for the company. The incident happened after a technician forgot to copy the new Retail Liquidity Program (RLP) code to one of the eight SMARS computer servers, which was Knight's automated routing system for equity orders. RLP code repurposed a flag that was formerly used to activate the old function known as 'Power Peg'. Power Peg was designed to move stock prices higher and lower in order to verify the behavior of trading algorithms in a controlled environment.[12] Therefore, orders sent with the repurposed flag to the eighth server triggered the defective Power Peg code still present on that server.[13]

When released into production, Knight's trading activities caused a major disruption in the prices of 148 companies listed at the New York Stock Exchange. For example, shares of Wizzard Software Corporation went from $3.50 to $14.76. For the 212 incoming parent orders that were processed by the defective Power Peg code, Knight Capital sent millions of child orders, resulting in 4 million executions in 154 stocks for more than 397 million shares in approximately 45 minutes.[13]

Knight Capital took a pre-tax loss of $440 million. This caused Knight Capital's stock price to collapse, sending shares lower by over 70% from before the announcement. The nature of the Knight Capital's unusual trading activity was described as a "technology breakdown".[14][15]

What are you proposing? That you spread your investments across VTSAX, SWTSX, FSKAX, ITOT, and SPY to reduce risk?

No, because VTSAX doesn't really sell holdings. Its turnover rate in 2019 was all of 4.1%.

If you're interested in learning about the fund's actual operations rather than being concerned for no reason, the Trillions podcast recently interviewed Gerald O'Reilly, the principal PM for Vanguard's big stock funds.

Vanguard has a strictly enforced “no cats allowed” rule to prevent this. Apparently, the cats are not happy about it and are defecting to Fidelity en masse. Watch for intense interest in the Fidelity Advisor Semiconductors Fund (FELIX).

Yes.

However I place such a risk in the negligible chance bucket.

But spreading one's assets between two fund families is not a bad idea if one is concerned.

Yes. If they using Interactive Brokers, there is a big button that says Close All Positions.. However if they accidentally sell everything, the fund will still have all the cash they got from the sales.

So as not to have this thread locked (despite my enjoying some of the comments), and by way of education, let's nudge the OPs question to the question he SHOULD be asking, rather than the question he asked.

"What kinds of situations, if any, do you think might make diversifying across funds, fund families, or brokerages a prudent thing to do?"

Examples:

-- The other day several people reported not being able to access their Vanguard accounts. It didn't last long, but what it if lasted days? What if the down payment on your home were in a Vanguard MMF you needed to transfer to ensure it gets to your bank in time before the closing?

-- There is fraudulent (or possibly fraudulent) activity in your brokerage accounts, so the brokerage locks you out. This might take time to resolve. Days? Weeks? Months? In the meantime, you can't transact. Might having assets at another brokerage be prudent?

I'm just throwing stuff out that have either happened, or in the range of plausible. As opposed to a meteor ever :wink: hitting the earth. I mean, what are the chances of THAT?

Don't give them any ideas. They could set off a panic that cuts the market by 50%, but if they had liquidated $1T, they could buy back twice as much at the bottom. When it recovers, rinse and repeat.

Tesla stock is falling. They need to split again.

On this serious question, days and weeks shouldn't matter at all. That's what savings and checking accounts is about. And your credit cards get you through. If that's a concern, you've got to do some re-planning. For the months long question or longer, it would help to involve an alternative. But if that was a problem, I'd be in contact constantly with the brokerage until it was resolved ASAP, and I don't mean months. By the time it hits a month, it should be escalated to the CEO office or legal proceedings should be considered. Guess you might need some funds to pay a lawyer.

The first is kind of a lack of preparation thing - just yesterday I did something a little ahead of time because there was a deadline approaching. I lost the time I was paying for between now and the deadline but so be it. Less hassle than dealing with a glitch delaying a last-day transaction.

The second point I think is more concerning. There is absolutely no assurance that you would ever be even partly compensated. So I can see that being a reason for multiple providers. Worse yet you might invest tens of thousands in litigation (using money you no longer have) and still lose. I don't know of instances of this happening but that doesn't mean it hasn't, or couldn't, occur.

If it did happen you might be better off holding VTSAX than a competitors fund!
Imagine - VTSAX sells the US Stock Market at volume it has driving prices down substantially (as stocks are flooding the market) across the board - likely crashing the market. The next day VTSAX can buy it all back at much lower prices driving prices back up. You have sold high and bought low - instant 1-day gains.

What you can do to prepare is limited. There might be market glitches that delay liquidation or system glitches that impact all accounts. Neither is predictable and for rare events, seems more trouble than it's worth. Moving funds from less liquid equities might be prudent, but if the account itself is the problem, it's no help. And if your concern is Vanguard, you can move it to your B&M bank, but their account system is just as vulnerable to these glitches.

More concerning is cyber attacks that could knock them out for prolonged periods. Banks have not been forthright with attacks for fear of loss of confidence, but municipalities have admitted to being victims more and more frequently. Here's where cloud solutions with automatic backup and recovery will be the long term solution, but might take a while for all these organizations to get there.

If every seller knows VTSAX is being forced to buy massive quantities of shares, everyone and their brother will frontrun and the ask prices of everything will go through the roof.

That being said, I think the most likely outcome of this exceedingly unlikely scenario is that circuit breakers trip seconds or minutes into the accidental selling process, and NYSE and NASDAQ probably retroactively cancel some transactions. This holds whether it's Vanguard or Blackrock or StateStreet or Fido or whoever fat-fingering the sell everything button.

So far only use is to caramelize cheese on top of grilled burgers during monthly afternoon “prayer meetings” with the guys over whiskey and cigars. But nice to be prepared. Good luck.

Well that would would be what happens to ETF VTI average daily volume around 3M shares so about $0.5B.

Do we have a circuit breaker in mutual funds?
Dhirendra Kumar explains why mutual funds do not have the 'circuit breaker' provision, unlike stocks

With regard to mutual funds, you can only estimate the increase or decrease in NAV by a certain percentage on the basis of the market movement. If you transact before 3:30 pm, you will get that day's NAV, which is decided only after the market is closed. Similarly, if you transact after 3:30, you will get the NAV of the next business day, which is not known to you.

That is a good question and I can’t even imagine. The fund is practically a &1 TRILLION fund. Not sure if that would be possible.

If you read the thread you will find that it is not possible.

It’s hard to read this thread because of the idiot comments that make up the majority of the responses. We should be more professional.

It’s an interesting question. Sounds like the sheer size will cause it not happen as the authorities would quickly step in.

Thanks to those who posted real responses.

Not something I worry about, but as I recall there have been instances of a (not Vanguard) index fund that made some "accidental" trades before the correct rebalancing date of the index. I'm still searching for a link to the news article, but it was awhile back. As I recall the fund company came in and corrected $ amount to make fund owners whole and ensure the fund continues to track the index.
... The nice thing about an "index fund" versus other funds, is you can actually see if the fund isn't tracking the third-party index. If you invest in an active fund you would have no idea if the fund manager meant to execute a particular trade at a particular time or not.

Yes, but it's running on Win 98 with a Cobol backend!
Funny, but I trust the Cobol back-end (W98, not so much...)

It was meant to engender a smile in this miserable year that is 2020. I also would trust the Cobol back end. :sharebeer

In order to liquidate, Vanguard has to sell the underlying securities for VTSAX during the trading day, and the circuit breakers for those individual stocks will trip. These are the circuit breakers I was referring to.

Also, due to Vanguard's fund structure where the ETF shares and mutual fund shares are different share classes for the same fund, and the nature of ETFs where the Authorized Participant keeps the price close to NAV during the trading day, the circuit breakers for VTI would also trip if an attempt was made to liquidate VTSAX's holdings. (As would the breakers for many, many other ETFs due to the price movement in the underlying securities they have in common with VTSAX/VTI).

Do you really think there is a button saying sell all? Or that the Vanguard system allows all the assets of TSM to be placed on a sell order?
