Should Passive Investors Actively Manage Their Trades?
Sida Li
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3967799
...


VI. Conclusion

In this paper I analyze the trading behaviors of passive-investing ETFs and calculate their transaction costs. I find that 56% of ETFs follow mechanical trading strategies that abruptly rebalance at the closing price of an index reconstitution date, although their trading dates and tickers are both publicly known 5 days before a reconstitution.

These ETFs experience a hefty 67 bps execution shortfall for their trades. This high cost is especially surprising because ETF rebalance trades are generally rule-based and not information-driven. Given these poor execution strategies, these uninformed mechanical traders are paying higher execution costs than informed traders.

Camouflaging either what or when to trade reduces transaction costs for ETFs. Self-indexing ETFs choose to track private indices to hide their trading interests. Opaque ETFs camouflage their rebalancing schedules and use alternative rebalance paces. The savings per trade involved with these two approaches are about 30–34 bps, which translates to about 9.6 bps per year of AUM. If 56% of U.S. ETFs operating in the $3 trillion passive ETF industry are not rebalancing optimally, $1.7 billion in rebalancing costs can be saved with smarter rebalancing strategies.

The optimal order-execution problem is complex for all market participants, so large buy-side institutional traders typically develop complex algorithms to execute their trades. For example, these investors deploy various order-splitting algorithms (Almgren and Chriss 2000, Obizhaeva and Wang 2013, Li and Ye 2021), use sophisticated order types (Li, Ye, and Zheng 2021), or even use atomic clocks (Baldauf and Mollner 2020) to minimize transaction costs and avoid being exploited by front-runners.

I provide evidence that even not-so-complex execution strategies, e.g., simply camouflaging either the timing or the underlying stock of a trade, can lead to considerable execution-cost savings for passive investors.

“The supposedly all-weather 60/40 portfolio is not ready for stagflation,” said Nancy Davis, founder of Quadratic Capital Management.



...
Wall Street pros are famously still at loggerheads over the fate of the trillion-dollar 60/40 complex -- only this time the balanced investment strategy is posting losses on a scale that’s shocking even its biggest critics.

With stocks and Treasuries tumbling anew thanks to the Federal Reserve’s increasingly hawkish policy direction, the time-honored method of allocating 60% to equities and 40% to fixed income has plunged about 14% so far this quarter. That’s a worse quarterly showing than in depths of the global financial crisis and during the once-in-a-century pandemic rout, according to data compiled by Bloomberg.

It’s the latest sign that the hedging power of bonds continues to vanish in the inflation era, sparking wealth destruction across American pension funds.

God help those paid to figure out if the asset class will break out of its existential funk or founder. It’s an increasingly high-stakes bet on whether the world succumbs to yet-more inflation, a recession or even stagflation.

Goldman Sachs Group Inc., for its part, thinks Treasuries remain dead as a hedge as central bankers tighten policy big time. By contrast, the likes of JPMorgan Asset Management reckon yields at multi-year highs will help bonds deliver the goods in the next crash.

“During 2008-2009, the utter collapse of stocks was a brutal hit to performance,” wrote Bespoke Investment Group analysts in a note. “But despite an enormous surge in credit spreads, bonds didn’t drop very far or for very long.”

Over the past decade, the likes of pension funds invested on the conviction that bonds would reliably keep producing steady income to offset equity losses in any market downturn. It largely worked, with the 60/40 strategy only ending down in two of the past 15 years -- all while posting modest volatility to boot. Even in the throes of the financial crisis, when stocks sapped performance, rallying Treasuries softened portfolio losses.

But this year, inflation has become a risk too big to hedge, hitting both bonds and equities together. The cross-asset selloff intensified in the past week thanks to the biggest Fed interest-rate increase since 1994 with another jumbo hike in the offing. All that is hurting American pension funds to a degree that few saw possible even just weeks ago.

The Pitfalls of Asset Management Research

How can we improve?

The problem of p-hacking is not unique to finance. Indeed, many other academic areas are realizing they have the same problem and are taking steps to address it. Indeed, the cost of p-hacking is arguably much higher in medical research—where a study’s results might mean the difference between life and death—than in finance where the primary concern is the size of the alpha.

Curiously, we are experiencing an ongoing debate in academic finance about whether p-hacking in financial research is a crisis. Our field is not special compared to other fields of study and does not warrant a free pass.

Investors can take a number of steps to mitigate the problem. First, be skeptical of both academic and practitioner research. Often a predetermined agenda or incentives make the results seem stronger than they are.

Second, take the research culture into account. For example, when presented with a new strategy, ask if the company keeps a record of all variables that were tried.

Third, try to quantify the costs of different mistakes (selecting a bad manager versus missing a good manager, see Harvey and Liu (2020b)).

Fourth, make sure the strategy has a solid economic foundation. Also, beware of ex-post theorizing (after discovering the result, a story is concocted).

Fifth, strategically ask questions such as “Did you try X?” If the answer is “Yes, and it does not work” and X is not reported, interpret this as a red flag. On seeing one cockroach, you can safely assume a dozen are behind the wall.

When Do Investors Freak Out? Machine Learning Predictions of Panic Selling
MIT Laboratory for Financial Engineering
https://jfds.pm-research.com/content/4/1/11
...


...

Second, we find that 30.9% of the investors who panic sell never return to reinvest in risky assets; however, of those who do, more than 58.5% reenter the market within half a year.

Third, we analyze the demographics of the investors who tend to ‘freak out’ under our definition (i.e., they make panic sales during periods of sharp market downturns), and find that a higher proportion of investors who are male, above the age of 45, married, have a greater number of dependents, or have declared themselves to have excellent investment experience or knowledge tend to freak out. (*)

Fourth, we find that the median investor earns a zero to negative return after panic selling. Calculating the opportunity cost of panic selling over time reveals that panic selling is suboptimal if executed in an improving market, but it is beneficial as a stop-loss mechanism in rapidly deteriorating markets.

Finally, we develop machine learning models to predict when investors might panic sell in the near future. Our set of predictive features includes the demographic characteristics of the investor, the investor’s portfolio histories, and current and past market conditions. This task is made difficult by the extreme rarity of panic sales. Nonetheless, our best-performing deep neural network achieves a 69.5% true positive accuracy rate and an 81.2% true negative accuracy rate, demonstrating that artificial intelligence techniques can assist in identifying individuals at risk of panic selling in the near future.

...


Panic sales are not random events. Specific types of investor, such as those with less than $20,000 in portfolio value, tend to liquidate more frequently than others. Subtle patterns in portfolio history, past market movements, and demographic profile can be exploited by deep neural networks to accurately predict whether an investor will panic sell in the near future.

Unfortunately, the problem of causation cannot be addressed with the data we have.

Therefore, our study does not address why investors panic sell. This topic, however, would doubtless be an interesting direction for future research.

Zum TeamViewer-Desaster z.Z.:
Zitat von Dreiseitensteak: ...Preise werden gemacht, sie entstehen nicht zufällig.
...

nein, Preise an nicht-manipulierten Finanzmärkten entstehen weitestgehend zufällig.

Auch der Kursverlauf der TeamViewer-Aktie entspricht weitestgehend, aber nicht vollständig, dem einer Zufallsvariablen. Auch hier sind die Preise in grober Näherung lognormal-verteilt.

Zitat von faultcode: das "TSI-System" ("TSI-Depot") des AKTIONÄRS wird wieder überarbeitet:
...

ich halte mal fest:

26.01.2021
Zitat von elmago: ...
Das TSI-System im Aktionär ist nicht viel wert, denn es wird als Musterdepot dargestellt, wo alle Kosten und Steuern unterschlagen werden. Dieser Thread entstand übrigens wegen der Schwächen des TSI 2.0.
Ich habe mal den TSI 2.0 über 5 Jahre nachgebildet, und zwar ohne Kosten und Steuern (siehe Chart). Mit einem DAX-ETF (buy and hold) fährst Du besser, weil während der Haltedauer keine Steuern und Kosten anfallen.

Antwort auf Beitrag Nr.: 69.572.544 von faultcode am 12.10.21 14:50:58HTML5 in der Chartechnik:

ich habe keine Ahnung welche Frameworks TSO benutzt, sehe aber, daß HTML5 + JavaScript für die Chartechnik im Web massiv um sich gergriffen hat.
Auch TradingView benutzt es: https://www.tradingview.com/HTML5-stock-forex-bitcoin-charti…

Hier, und woanders, scheint wohl der geradezu manische Zwang zur "Mobility" oft ausschlaggebend gewesen zu sein: HTML5 Canvas technology ensures that (unlike pictures) this chart will always look perfect on any device.

z.B.:

www.chartworks.io


Der rasche und massive Aufstieg der "Mobile Stock-Trading App Robinhood" ist hier mMn Ursache und Sympton zugleich.

=> für mich sind aber "Pictures" (ohne Echtzeit- und Intraday-Daten) auf dem Windows 10-Desktop gut genug ;)


Im Hintergrund spielt mMn auch der anhaltende Krypto-Boom eine Rolle; ein Umfeld, wo ganz offensichtlich kein besonderer Wert auf ausgefeiltere Charts gelegt wird.

Und ich meine Technical stock charts, also keine Watchlisten oder Portfolio-Verwaltung mit Analysen oder Dashboards mit Market overviews.

Und auch kein Wertpapierhandel aus einer App heraus; ja, dort war/ist das große Geld mit zu machen. Zumindest hoffen das die Macher :rolleyes:


nebenbei: Volume by price charts (volume profile) sind bei der ansonsten hochgelobten Koyfin-Plattform wo zu finden?
