This time is different. Stocks will always go up. And pigs can fly. Given that pigs are highly intelligent, don’t bet against them. That said, investors might want to take at least the first two statements with a grain of salt.
In the 1990s, stocks continued to rise relentlessly for years, even after then Fed Chair Greenspan warned of irrational exuberance in late 1996.
Last decade, the rally in home prices continued as ever more people appeared convinced that home prices never fall.
This time around, we are eight years into a bull market. As in those times, investors have all but given up betting against conventional wisdom. Much of that is because it has cost investors dearly to bet against the markets. In fact, it has been so costly to bet against the market that some advisors who have been cautious are no longer in business. And I’m not just talking about short sellers, but also many who have – in our view prudently – diversified beyond a traditional “60/40” stock/bond portfolio. We know of advisors who positioned their portfolios more aggressively not because they thought the markets were going higher, but because they were losing clients for underperforming the S&P 500.
Some things are different.
The investment industry has evolved to provide ever more index products, with lots of touting how active management is dead. If that were true, we wouldn’t have a plethora of index funds for many slices of the market as selecting anything but a market portfolio is the very definition of active management. Then again, when “everything” goes up, does it really matter what you buy, so long as investors buy something? So what is different?
- A new breed of liquidity providers
In the old days, we had banks and floor traders provide liquidity. Dodd Frank has significantly cut back the type of trading banks may engage in. And floor traders have been replaced by computers. Floor traders on the New York Stock Exchange used to have a duty to make orderly markets with the ability to slow down trading to match buyers and sellers. That philosophy lost out to the philosophy that speed is more important than price, meaning that if an investor wants to trade, let them trade instantaneously, even if the price needs to adjust sharply.
Today’s liquidity providers include ETF market makers and hedge funds. They will provide all the liquidity in the world, so long as everything appears orderly. But let the algorithms flag an abnormality, and their systems may go offline. Without going into the arcane details how market making works, let’s take a common model (there are others) how ETFs trade:
– A so-called lead market maker gets incentivized to offer a tight spread for an ETF (the incentive comes from the exchange giving the market maker a rebate on the price, i.e. giving them a price advantage through actual cash; the rebate comes from the exchange fee investors are paying).
– There’s a plethora of other market makers also providing liquidity, enabling what appear to be mostly efficient markets. These other market makers also get incentives from the exchange, albeit lower ones than the lead market maker. As a result, it creates a structure where all market makers can offload their risk to the lead market maker. This makes it comparatively easy for market makers to make markets in thousands of ETFs, as they don’t need to understand too well the ETF they are providing liquidity for; all they need to know is that they can offload their risk to the lead market maker.
– This system works great until the lead market maker has a glitch and takes its systems offline. When that happens, other market makers see that the party that is supposed to be best informed (the lead market maker) is stepping away. Not surprisingly, everyone else also steps away, causing spreads to widen.
– A flash crash can then happen if investors place large market orders just as liquidity providers are offline.
- Lower volatility?
Markets have been rising on the backdrop of low liquidity. Why has volatility been so low? We see two primary drivers: the rise of machines, as well as central banks:
To the extent that information is processed correctly, trading firms focused on ‘big data’ scanning the news flow automatically may well speed up how readily new information is absorbed in the market. As such, the rising influence of machines in the market may well contribute to the lower volatility we have seen. That said, we wonder how big that impact is.
When ECB chief Draghi said, he’ll do “whatever it takes” to save the euro a few years ago, he put into plain English what had been happening for some time since the onset of the financial crisis: taking risk out of markets. A few weeks ago, he said in a press conference there’s no need to be concerned about upcoming events in the Eurozone because we can’t do anything about the outcome anyway; and if something bad were to develop for the markets, the ECB would take the appropriate action. Differently said: heads, I win; tails, you lose.
More abstractly speaking, central banks have compressed risk premia through quantitative easing and their forward guidance.
Some things stay the same…
In our analysis, all else equal, lower volatility warrants higher valuations. That’s because in a classic valuation model where asset prices reflect the present value of discounted future cash flows. Lower volatility increases valuations because future cash flows are discounted at a lower rate. This warrants the question whether volatility will stay lower, permanently.
I have my doubts. On the contrary, in my assessment the hallmark of any asset bubble is low volatility. Capital misallocations happen when risk is underpriced. When it is a central bank, be that the Fed, the ECB or another central bank causing the underpricing of risk, it doesn’t suddenly become rational. Sure, one can argue that it is a quixotic task to fight the Fed, but that doesn’t mean an asset bubble won’t be created and won’t burst.
Get ready for the crash…
We believe one of the reasons the Fed has been so reluctant to raise interest rates is because of the “taper tantrums” the market has exhibited. Because we believe the economic recovery was driven by asset price reflation, the Fed has been hesitant to withdraw stimulus too early, to avoid deflationary forces taking over again. The Fed has been trying to engineer what we call a “cliff walk” trying to normalize interest rates without causing a shock to asset prices.
Of late, the Fed has been emboldened: with a few speeches, the market delivered the Fed a rate hike on a silver platter, without equity markets having a fit. Indeed, some Fed officials have been all chirpy of late, talking about three to four interest rate hikes this year. Fed officials are acting as if they were at cocktail parties bragging about their great trade, pardon, rate decision. The reason I’m skeptical is because the folks at the Fed are so data dependent that they
