Howard Marks: This Is What "Investing Without People" Looks Like

In his latest letter titled "Investing Without People", Oaktree's iconic founder and distressed investor Howard Marks becomes the latest to opine on the rise of index funds, the decline of human investors and how the advent of computer-driven trading is reducing the role of people in the markets while creating room for a select few money managers to excel.

In the 17-page memo (attached below), Marks analyzed the effects of three industry trends: the increased use of passive, quantitative and artificial intelligence strategies in investing. On the first, Marks sees money continuing to flow into index products including exchange-traded funds: after all as long as the market keeps rising, and ETFs outperforming active investors, the only differentiator remains price, and here nobody can beat passive. Still, a few active managers will outperform and remain in demand, according to Marks

The bottom line is that the wisdom of investing passively depends, ironically, on some people investing actively. When active investing is dismissed totally and all active efforts cease, passive investing will become imprudent and opportunities for superior returns from active investing will reemerge. At least that’s the way I see it.

Marks was also bullish on the need for humans even as machine learning advances in its ability to spot and execute trades.

Focusing on passive investing and ETFs, Marks poses the following key questions:

  • The first question is, “Is passive investing wise?”
  • Thus the second question is, “What are the implications of passive investing for active investing?”
  • The third key question is: “Does passive and index investing distort stock prices?”
  • Question number four: “Can the process of investing in indices be improved relative to simply buying the stocks in proportion to their market capitalizations, as the indices are constituted?
  • Question number five: “Is there anything innately wrong with ETFs and their popularity?”

Of these, the most interest question is #3 as it has long preoccupied traders who now feel like they are a second fiddle to mere fund flows which have made fundamental, bottom-up investing obsolete. Here is Marks:

“Does passive and index investing distort stock prices?” This is an interesting question, answerable on several levels.

The first level concerns the relative prices of the stocks in a capitalization-weighted index. People often ask whether inflows of capital into index funds cause the prices of the heaviest-weighted stocks in the index to rise relative to the rest. I think the answer is “no.” Suppose the market capitalizations of the stocks in a given index total $1 trillion. Suppose further that the capitalization of one popular stock in the index – perhaps one of the FAANGs – is $80 billion (8% of the total) and that of a smaller, less-adored one is $10 billion (1%). That means for every $100,000 in an index fund, $8,000 is in the former stock and $1,000 is in the latter. It further means that for every additional $100 that’s invested in the index, $8 will go into the former and $1 into the latter. Thus the buying in the two stocks occasioned by inflows shouldn’t alter their relative pricing, since it represents the same percentage of their respective capitalizations.

But that’s not the end of the story. The second level of analysis concerns stocks that are part of the indices versus those that aren’t. Clearly with passive investing on the rise, more capital will flow into index constituents than into other stocks, and capital may flow out of the stocks that aren’t in indices in order to flow into those that are. It seems obvious that this can cause the stocks in the indices to appreciate relative to non-index stocks for reasons other than fundamental ones.

The third level concerns stocks in smart-beta funds. The more a stock is held in non-index passive vehicles receiving inflows (ceteris paribus, or everything else being equal), the more likely it is to appreciate relative to one that’s not. And stocks like Amazon that are held in a large number of smart-beta funds of a variety of types are likely to appreciate relative to stocks that are held in none or just a few.

What all the above means is that for a stock to be added to index or smart-beta funds is an artificial form of increased popularity, and it’s relative popularity that determines the relative prices of stocks in the short run.

The large positions occupied by the top recent performers – with their swollen market caps – mean that as ETFs attract capital, they have to buy large amounts of these stocks, further fueling their rise. Thus, in the current up-cycle, over-weighted, liquid, large-cap stocks have benefitted from forced buying on the part of passive vehicles, which don’t have the option to refrain from buying a stock just because its overpriced.

Like the tech stocks in 2000, this seeming perpetual-motion machine is unlikely to work forever. If funds ever flow out of equities and thus ETFs, what has been disproportionately bought will have to be disproportionately sold. It’s not clear where index funds and ETFs will find buyers for their over-weighted, highly appreciated holdings if they have to sell in a crunch. In this way, appreciation that was driven by passive buying is likely to eventually turn out to be rotational, not perpetual.

The vast growth of ETFs and their popularity has coincided with the market rally that began roughly nine years ago. Thus we haven’t had a meaningful chance to see how they function on the downside. Might the inclusion and overweighting in ETFs of market darlings – a source of demand that may have driven up their prices – be a source of stronger-than-average selling pressure on the darlings during a retreat? Might it push down their prices more and cause investors to turn increasingly against them and against the ETFs that hold them? We won’t know until it happens, but it’s not hard to imagine the popularity that fueled the growth of ETFs in good times working to their disadvantage in bad times.

Elsewhere, while complimenting algos which can handle more data, make fewer mistakes and never forget to rebalance but have their limits, pointing to the world's most successful quant hedge fund - Renaissance's Medallion - noting that even it has a cap on the amount of capital it can invest successfully, he notes that he doubts "computers can do what the very best investors do," bringing up such examples as sizing up the quality of a company’s chief executive officer, sift through venture capital pitches or tell which new building will attract the most tenants.

I doubt computers can do what the very best investors do:

  • Can they sit down with a CEO and figure out whether he’s the next Steve Jobs?
  • Can they listen to a bunch of venture capital pitches and know which is the next Amazon?
  • Can they look at several new buildings and tell which one will attract the most tenants?
  • Can they predict the outcome of a bankruptcy reorganization where the parties may have
  • motivations other than economic maximization?

"Computers, artificial intelligence and big data will help investors know more and make better quantitative decisions. But until computers have creativity, taste, discernment and judgment, I think there’ll be a role for investors with alpha."

Deep inside his latest opus, Marks takes the time to sneak in one of his trademark ETF warnings:

Leaving aside the question of whether a manager can add value by predicting the short-run direction of a market – about which I would be highly skeptical – I think one of these days, this investor may want to execute a trade that wouldn’t be doable in the “real” high yield bond market, and he’ll find that it can’t be done via ETFs either. In short, building a strategy around the assumption that ETFs can always be counted on to quickly get you into or out of an illiquid market at a fair price seems unrealistic to me. The truth on this will become clear when the tide goes out.

He, then, concludes with the following assessment of what the rise of passive, quant and artificial intellgience means for the future of investing:

  • Most people can’t and don’t beat the market, especially in markets that are more-efficient. On average, all portfolios’ returns are average before taking costs into account.
  • Active management introduces considerations such as management fees; commissions and market impact associated with trading; and the human error that often leads investors to buy and sell more at the wrong time than at the right time. These all have negative implications for net results.
  • The only aspect of active management with potential to offset the above negatives is alpha, or personal skill. However, relatively few people have much of it.
  • For this reason, large numbers of active managers fail to beat the market and justify their fees. This isn’t just my conclusion: if it weren’t so, capital wouldn’t be flowing from active funds to passive funds as it has been.
  • Regardless, for decades active managers have charged fees as if they earned them. Thus the profitability of many parts of the active investment management industry has been without reference to whether it added value for clients.

Marks notes that it is important to note that the trend toward passive investing hasn’t occurred because the returns there have been great. "It’s because the results from active management have been poor, or at least not good enough to justify the fees charged" but "Now clients have wised up, and unless something changes with regard to the above, the trend toward passive investing is going to continue. What could arrest it?"

  • More active managers could become capable of delivering alpha (but that’s not likely).
  • The markets could become easier to beat (that’ll probably happen from time to time).
  • Fees could come down so that they’re competitive with passive investment fees (but in that case it’s not clear how the active management infrastructure would be supported).

In other words, more bad news for active investors:

Unless there are flaws in the above reasoning, the trend toward passive investing is likely to continue. At the very least, it reduces or eliminates management fees, trading costs, overtrading and human error: not a bad combination.

Of course, there are active investors who outperform. Not most, and not half. But there’s a minority who do earn their fees, and they should continue to be in demand.

Still, Marks leaves a little silver lining of hope for carbon-based traders:

Finally, I view this situation kind of like index investing: if the day comes when intelligent machines run all the money, won’t they all (a) see everything the same, (b) reach the same conclusions, (c) design the same portfolio, and thus (d) perform the same? What, then, will be the route to superior performance? Humans with superior insight. At least that’s my hope.

It's also the hope of every human trader reading this as the alternative is extinction.

considering the 340 ticks I made last night on NQ's little dump out, both long and short,  I would tend to agree.

 

   the only way the machines can keep a carbon based trader from profiting, is if they race to the bottom and take volatility out of the market, so that a "big" move is only a few ticks, and large "earthquakes"in markets are a couple of dozen ticks that happen in milliseconds.

 

    If the machines can provide that type of efficiency in markets, then yes, humans will have to go do something else.   But that is not realistic unless machines are making fiscal and political policy as well.  not to mention natural disasters, such as weather events,  acts of war, industrial accidents and other short and long term market moving events.

So you finally fixed your typos but you still aren't professional enough to look into the details of your fake ad. I guess it all comes up to the level of intellect that is required to do the job which I do not wish to discuss, for I just had lunch. 

$24551 @85/h gives roughly 290 hours of porno work per month. Man if that's not milking people like cows then what is this? 

Are you one of these Jewish porn moguls?

It might not be analogous, certainly not in terms of the salary levels, but the plight of carbon-based traders, making their mark on what falls outside of the index funds, reminds me of $10 to $13-per-hour call centers, where a lot of passive, compter-generated, closed-by-bots sales come in overnight via the computer system.

Managers hand out those done deals to their pets. Frequently vacationing crony-parent managers hand almost all of those bot-closed accounts to fellow mommas who are likewise missing from their cubicles for many mornings, afternoons, days and weeks beyond PTO & pregnancy leave. Non-degree-holding managers hand those accounts to fellow non college grads, etc., etc., etc., with many different social pecking orders present in inside  sales, not just the near-ubiquitous crony-mom gangs in the corporate back offices. 

Many salespeople, myself included, do not even want it other than as a matter of economics. When you are not taking inbound calls, the days in these jobs are excruciatingly long & boring if you do not cold call all day long to generate sales. When you do that, day after day, all day long and relentlessly, you end up closing a lot of sales that you—not the computer—generated. You KNOW that the colleagues who are handed the bot-generated sales do not do this. You know, because due to the density of the cubicles, you can hear every single word they say, or rather every call they do not make while playing on social media or leaving work (for baby, for baby). 

Either way, whether generated by a website or by a “carbon-based” inside salesperson, these sales go through some human processing. I am always on the side of the carbon-based employees except when I remember all of the cutthroatery, like managers who overpraise the employees who generate a lot of sales to add to the bulk of sales coming in over the internet. They pump up the hard workers in a fake way to get them to sell more, which pumps up the manager’s bonus.

This causes a lot of venom hurling by some in the frequently absentee crowd that get their bot-generated sales doled out to them. Managers churn & burn the salespeople who put in all the effort, knowing that inside salespeople—even the few who actually work hard and come to work every day, staying at work all day and closing a lot of sales—are 100% expendable.

Salespeople are not like technical or medical employees; they have no leverage even when they produce a lot. Good salespeople are a dime a dozen. The interesting thing is that the lazier and the more absentee the inside salesperson, the greater his / her job longevity. The job longevity is in direct proportion with how much the underling’s social characteristics echo or do not compete with the manager’s social characteristics & skills. 

Bots—unlike humans—could care less about all of the maneuvering and the unfairness. Bots just get it done. But like this article says,  a greater volume of carbon-based finesse will be necessary to pick up the pieces in any reset situation. It won’t just be humans, hired to sell the more difficult-to-close stuff at the margins of popularity, but humans hired to clean up a catastrophic mess unforeseen by bots who sold in drama-free zones. Since humans—even smart ones—are often motivated by emotion, bots might miss some key emotional strain, causing the card house to tumble.

But they are now being trained to program themselves.... thusly does their 'ghost' awaken.... all of this has happened before... but the history books don't survive such times... especially when the rulers want it hidden.... so they can do it all again.. thinking they will succeed this time.. not like last time.. but generations pass, and that 'whispering' in the Roman general's ear about being merely mortal is lost... and greed takes over... financialization kicks in.. takes over.. and the usual BS show begins... same as now.... same thing everytime.

The first question is, “Is passive investing wise?” 

not always.

Thus the second question is, “What are the implications of passive investing for active investing?”

BAD Turn around time.  Look at the TSP with 3 IFT's a month 

The third key question is: “Does passive and index investing distort stock prices?”

RUSSEL 2K vs GOLD   um, Yeah

Question number four: “Can the process of investing in indices be improved relative to simply buying the stocks in proportion to their market capitalizations, as the indices are constituted?

Aggrigation of stocks makes things harder to track in my opinion, you have to unpack WHY things are good/bad but it can be good when it's simple for visualization purposes to show it going up or down..

Question number five: “Is there anything innately wrong with ETFs and their popularity?”

popularity always screws things up in my experience.

At least that’s the way I see it.

It is not ironic. The whole idea of efficient markets is based on no one really knows the price so everyone will try their guess and we will see where it ends up and that of course will be the "real" price. Feynman gave the analogy of the Chinese game of how long is the emperor's nose. Since no one is allowed to see the nose, everyone guesses and the one closest to the average wins.

As a Carbon Person gets older their cohort dies ever more quickly and that World, the world of that cohort dies with them until when the last person finally dies it is only tiny then winks out forever. We doe and our world dies with us.

To achieve superior returns from active investing, one has to believe others will be active.  If not, it's same ole same ole, as the big names dominate from passive fund flows.
