Bubble? What bubble?
In a blog shared with Traders Magazine, Jared Dillian, former ETF Head Trader for Lehman Brothers, wrote that while assets have been fleeing actively managed ETFS and funds and into passively managed ones, is concerned the Index sector could be heading towards a bubble.
I want to talk about the idea that this strategy has become so popular that it is a bubble in and of itself, Dillian began. This is a frequent topic of discussion online. The index fund bulls/promoters usually point out that just a small fraction of assets have switched to passive-there could be a lot more to go. That is true. The index fund bears/detractors point out all the distortions that are happening from indexing.
Such as:
- It has ruined long/short strategies
- It is screwing up corporate governance
- It is causing valuation distortions
Dillian reminded that if one lived through the dot-com crisis, there were poople day-trading at their desks at work, cab drivers giving riders stock tips, and so on. Mania. So =, he asks, what if indexing is a mania unto its own?
What follows is Dillians blog.
Ive been yapping my trap about these vol-selling monkeys for some time-we may have finally reached peak vol absurdity.
As you may have seen, the VIX dipped under 10 on an intraday basis the other day:
Meanwhile, short interest has reached an all-time high in VXX, the ETN that is supposed to track the VIX.. Remember, if you buy VXX you are getting long volatility, so basically what we are seeing is an overabundance of people rushing in tosellvolatility… at the all-time lows.
No bubble here.
We spent last week talking about bubbles-is there a bubble in short volatility strategies? I think there might be.
Please stop and readthis terrific piece by Dean Curnutt, CEO of Macro Risk Advisors, on Bloomberg View. In it, he talks about the idea that financial insurance is different than conventional insurance. With insurance against hurricanes or fires, for example, the event you are trying to insure against is truly exogenous. Hurricanes (for all intents and purposes) are independent events, and occur without respect to how many people buy insurance.
But that is not the case with financial markets insurance (like options). As opposed to earthquakes, which are exogenous events, a crash (caused by a rapid unwinding of positions) can be anendogenousevent, as Curnutt explains. People put on a trade, it works, which encourages more and more people to pile in… until it eventually stops working. Then everyone will want to get out-all at once.
As I have written before, selling volatility has worked so well for so long that many people believe it to befree money. Shorting VXX works when volatility goes down and the term structure of volatility steepens. What happens if volatility goes up and the term structure inverts-and stays inverted? Road pizza.
I try not to bring this up in mixed company, but this is just one of many dashboard warning lights that are flashing magenta right now. The other ones I talk about all the time are overheated housing markets in Canada, Australia and Sweden-it appears that Canada is cresting as we speak. But what I really want to talk about is the idea that we might possibly have an indexing bubble.
Is There An Indexing Bubble?
Everyone knows by now that assets have been fleeing actively managed funds into passively managed mutual funds and ETFs. Its an old story. Everyone knows about the popularity of Vanguard. Some people have made their reputations on this. The story is compelling-invest in this product that usually beats most competitors but costs a lot less. Where do I sign up?
Ill poke holes in that logic some other time. For now, I want to talk about the idea that this strategy has become so popular that it is a bubble in and of itself. This is a frequent topic of discussion online. The index fund bulls/promoters usually point out that just a small fraction of assets have switched to passive-there could be a lot more to go. That is true. The index fund bears/detractors point out all the distortions that are happening from indexing, like:
- It has ruined long/short strategies
- It is screwing up corporate governance
- It is causing valuation distortions
Entertain this thought for a moment. If you lived through the dot-com crisis, you remember what that was like. People day-trading at their desks at work, cab drivers giving you stock tips, all that kind of stuff. Mania. The stuff we were talking abouttwo weeks ago.
What if indexing is a mania unto its own?
Clearly, there isnt the euphoria there was in 1999, but people are pretty excited about their index funds. Excited enough that Vanguard gets $2 billion in new assets a day. Meanwhile, long-short guys have a tough time scratching together $50 million for a launch.
People arent bullish on stocks–they are bullish on thestock market. And philosophically, nobody is really thinking about the S&P 500 stocks as 500 stocks. They are thinking about it as an asset unto itself. It has a price. And, when people talk about indices, they dont talk about the benefits of diversification anymore.
Remember how this stuff works-you dont necessarily need an exogenous shock for this trade to fall apart. As previously described, greed takes over, and it can just stop working and unwind.
What would an indexing unwind look like? Down 20%–thought you were diversified!
Just Spitballing Here
Just kicking some ideas around. Privately, I would say that, while popular, indexing may not have reached bubble stages yet. This is all new territory, so I dont know.
What I do know is that stocks in the U.S. have become very expensive, which should not be a controversial statement. I dont really want to own expensive stocks. Neither should you.
In theStreet Freakportfolio, there are only a handful of U.S. stocks. And most of them are not expensive. There are lots of opportunities that arenotstocks in the S&P 500 Index. There are lots of places in the world that are attractive right now. It just takes a little digging. Thats what I do for my subscribers.
One final thing (and this is important)-Id like to invite you all to become subscribers to my new podcastThe Monthly Dirtcast. In my writing I tend to be the blind-you-with-science gearhead, but this is a very different sort of financial podcast. Its not all about markets and macro. Its about finance, highbrow-and lowbrow. In my latest episode, I interview a broker who buys and sells dental practices. Sounds boring, until you learn that private equity is getting involved.
