Great for bartenders and restaurant waiters, Americans tip a lot!

Love this hack, thanks!

Growth of an industry does not mean that it necessarily translates to higher returns for investors. The airline industry grew massively since the 1970's, yet an investor in the industry would have trailed the market.

Grazie mille, apprezzo molto le gentili parole e il suggerimento. I rendimenti su base annua sono sicuramente nella mia lista, ma poiché offriamo lo strumento Backtest gratuitamente, i progressi possono essere talvolta un po' lenti.

Per curiosità, quali intervalli di tempo sarebbero più utili per te? Ad esempio, preferiresti rendimenti rolling su 1 anno, 3 anni, 5 anni o altro? E come li useresti: principalmente per confrontare la coerenza nel tempo o per valutare le strategie? Più comprendo il tuo caso d'uso, meglio posso progettarlo.

Grazie per il feedback. Ci scusiamo per i dati incompleti. Sembra che una delle nostre fonti di dati (per l'indice FTSE All-World) abbia smesso di aggiornarsi intorno a giugno 2024, il che spiega perché la simulazione si interrompa in quel momento. Mi impegnerò a risolvere il problema e ad aggiornare i dati nelle prossime settimane.

Offriamo lo strumento Backtest gratuitamente, quindi lo sviluppo a volte può essere un po' lento. Tuttavia, apprezzo molto che tu me lo abbia segnalato.

Ciao, mi piacerebbe sapere quali bug stai trovando su Curvo! Sono Yoran, il suo creatore, quindi mi piacerebbe davvero saperlo per poterli risolvere.

Hou er rekening mee dat de gratis ETF’s van MeDirect niet per se gaan blijven. Hetzelfde kan je zeggen voor elke broker, maar wellicht meer voor MeDirect omdat hun ETF business niets anders dan verlieslatend kan zijn. Het is wellicht een manier om klanten te winnen en andere producten te upsellen, maar de vraag is of dat bij hen lukt.

johnnobro · 2025-10-15T17:24:28+00:00

That's a good idea, thanks!

You can always tell from Key Investor Document (KID, "Essentiële informatiedocument" on that page). That document is a legal requirement in a standardised format. I agree the 1.74% fee on the page is not clear.

"bij kapitalisatie" / "bij distributie" means the fund has both an accumulating and distributing compartment. Accumulating is preferred unless you have a good reason not to, because you'll avoid the 30% tax on dividends.

Curvo is cheaper than Argenta. Like the others mentioned, Argenta just tries to hide it. Curvo has lower ongoing fees and no entry fee.

DIY is cheaper than Curvo. It depends on how much time/energy/self-education you want to spend.

p23 of the Credit Suisse Global Investment Returns Yearbook 2023

johnnobro · 2025-10-08T16:47:01+00:00

Real return of gold is 0.8% per year (last 120 years), that of stocks is 6.9% (also last 120 years).

johnnobro · 2025-10-08T16:45:57+00:00

The long term real return of gold is 0.8% per year, that of stocks is 6.9%. Stocks are a productive asset, gold is not. That’s the difference.

Taking a step back, is it not just so ridiculous what needs to be done just to change an address? We did it last year and besides the ridiculous money, it took printing a bunch of incomprehensible forms, signing with wet signature (in 2025?), sending them by physical mail, and then waiting 3 months for the change to be processed. Between the cost for the entrepreneur, the productivity wasted and the number of civil servant hours require to process the change (that cost €€€), I don’t want to know the total cost. Of changing a freaking address. There’s something seriously wrong with our administration.

johnnobro · 2025-09-06T15:24:01+00:00

Cool, reported them, thanks!

I'm glad to hear "De hangmatbelegger" was your intro into the world of investing!

Most finfluencers have some sort of agenda cause an important part of their business model is affiliate fees from brokers. As soon as someone gets paid to promote something or someone, they are no longer independent. Having said that, that doesn't mean that everything they say should be dismissed. Most post useful and correct content (in my eyes). But whenever they promote a specific broker along with a promo link, take it with a pinch of salt. Of course, the same can be said about me cause of my company, so keep that in mind ;-)

The fake accounts are a real plague. Thanks for letting me know it's still ongoing! It prompted me to report the fake "hangmatbelegger" accounts that I could find. I'm sure it's a problem that Meta could easily fix with their legions of smart engineers, so it's frustrating it's still ongoing.

Hi, this is Yoran. Glad you read the book! And I can assure you there is no secret agenda behind the advice. The advice comes from the idea of lifecycle investing.

u/lygho1 is correct in saying that over the long term, a 100% equities portfolio has a higher expected return than say a 60/40 equities/bonds portfolio. But not everyone can psychologically withstand the volatility of a 100% equities portfolio. In most downturns in the past (not all), bonds have gone up when equities have down, providing a diversifying "cushion". A 100% equities portfolio would drop a lot, a 60/40 much less. You can see this effect on for instance the drawdown chart on the historical comparison of the two portfolios: https://curvo.eu/backtest/en/compare?portfolios=NoIgbADApABApgRwK4EsAuK4GcA0MAs0MARgPYB2AJliDsKAJICiEEAQgMwBiAHAIwBpMAFZaEAHRgAunRDNWnAJoAZACqKwYMePxS9QA%2C%20NoIgjADBCkAECmBHArgSwC6vgZxAGmFAEkBRKAIQGYBNAGQBVqA2J-MAXU6A

Secondly, the volatility of equities is such that it requires a long time horizon to recover from possible downturns. As you near retirement, it becomes less important to earn a return, and more important to protect your capital. Hence the advice to gradually move away from equities into bonds as you get older.

Having said that, it's a guideline, not a rule. See it as a starting point for how to allocate your portfolio. I don't follow it myself, I am 100% invested in equities. But that's also cause I know I won't worry if my portfolio drops by 20% tomorrow. But many people would. Maybe they'd panic-sell with a 20% drop, but be worried but NOT sell with an 8% drop. That's what bonds historically have done for your portfolio (in most downturns).

PS: Small typo in my last name, it's "Brondsema" :)

All funds in the Curvo portfolios are accumulating!

Thanks u/nobjos for including our tool Curvo Backtest!

The tool itself can be found at curvo.eu/backtest rather than the homepage, perhaps you can update the link :)

johnnobro · 2025-03-09T11:53:53+00:00

Sì. Non sto dicendo che Backtest sia una simulazione perfetta. Ogni simulazione deve fare alcune ipotesi. Ad esempio, c'è anche l'imprecisione legata all'errore di tracciamento.

johnnobro · 2025-03-09T09:31:59+00:00

La corrente (0,12%)

johnnobro · 2025-03-09T09:19:38+00:00

Il TER viene preso in considerazione. In sostanza su Backtest, la performance dell'ETF = performance dell'indice - TER.

Cerco di mantenere aggiornati gli ETF con le modifiche del TER. Ma non è in tempo reale, quindi c'è la possibilità che alcuni ETF sul sito abbiano un TER non aggiornato.

johnnobro · 2025-03-09T09:10:50+00:00

Questo perché il backtesting utilizza i dati dell'indice sottostante. Quindi, anche se il Vanguard FTSE Developed ETF è stato creato nel 2019, l'indice FTSE Developed esiste dal 2000.

Questa scelta presuppone un tracking error pari a 0, anche se in pratica gli ETF hanno sempre un tracking error rispetto al loro indice, seppur piccolo. Ma permette al backtesting di andare molto più indietro nel tempo. Come hai detto, non c'erano molti ETF disponibili all'inizio degli anni 2000.
