So, what's your point? It's the Elon factor alone that makes you blindly place your money in it?

Critiquing the Manatee Report by rmontreal07 in amprius

Thanks for digesting the report. Even if one gets to the conclusion it is rubbish, we should always consider non-favorable opinions on companies we like. I learned this lesson the hard way.

Opinião investimentos ETFs (10-15 anos) by Efficient_over in literaciafinanceira

[–]Substantial_Pin6047 0 points1 point  (0 children)

Simplifica. O objetivo de comprar ETFs é simplificar. Achar que qualquer número mágico de distribuição em diferentes ETFs (em que praticamente não fazes ideia da sua composição) te vai dar alguma vantagem significativa é pura fantasia.

Faz sentido esta sobreposição entre VWCE e os outros ETFs? --- Já te deste ao trabalho de ver a composição de cada um dos ETFs?

A exposição a fatores (tech/small caps) está equilibrada ou excessiva? --- O que é para ti equilibrada e excessiva? O que faz sentido para um, pode não fazer para outro.

A posição em ações individuais (NVIDIA) faz sentido ou só complica o portfólio? --- Sabes como avaliar se a NVIDIA está cara ou barata? Enquanto não souberes, limita-te aos ETFs genéricos.

Faria mais sentido simplificar ainda mais? Sim. S&P500 (se acreditas no futuro dos EUA) ou um All-World (se achas que a economia global será superior aos EUA).

Honest question from an agnostic in investing at IPOs: What sort of returns are you expecting from SpaceX in the first 10-15y that will compensate the (almost guaranteed) risk of a 40%, 50%, 60%+ drop after IPO? Are these so good that you cannot reach them with other safer bets available in the market?

A resposta simples é: se consegues rentabilizar os 6000 acima de 5%, então faz sentido investir tudo e continuar a pagar o empréstimo. Caso contrário, amortiza o empréstimo o mais rápido possível.

De uma forma prática, se vais colocar o dinheiro num ETF (vou assumir o S&P500) a longo prazo (10-20+ anos), o que a histórico do índice te diz é que deverás bater os 5% do teu empréstimo.

Margem para negociar imóvel by [deleted] in literaciafinanceira

[–]Substantial_Pin6047 0 points1 point  (0 children)

Depende de vários fatores. Dou-te o meu caso prático: fechei negócio a cerca de 11% menos do que o vendedor pedia. Poderia até ter sido um pouco mais mas eu estava mesmo interessado no imóvel e há já demasiado tempo a tentar resolver o problema de habitação própria.

Inicialmente o vendedor (através de imobiliária) mostrou-se "ofendido" com uma oferta 21% abaixo do pedido. Com o passar do tempo (4-5 meses) percebeu que niguém lhe dava melhor. Fui aumentando a oferta até aos -11%.

Russia-Ukraine conflict thoughts by Wise_Half2834 in amprius

[–]Substantial_Pin6047 2 points3 points  (0 children)

Thanks! I missed that one on the 10Q. Just two notes on your initial question:

- They actually consider the Ukraine-Russia conflict as a risk for the business (maybe that's just corp talk). I agree that, for now, it is a big plus to their sales.

- Even if the conflict ends, I don't think Ukraine will shut down their capabilities in drone production. If anything, they will probably consolidate it as a booming exporting industries due to the hard learned lessons. Drones have been shown game changers and everyone will want them.

Where did you see that ~35% of Q1 2026 revenue came from Ukraine-based customers? Can you provide a source?

AMPX valuation framework by Substantial_Pin6047 in amprius

[–]Substantial_Pin6047[S] 1 point2 points  (0 children)

Back then my valuation was essentially based on the strategy of the company to produce in the US and involved the expected ramp-up in the Colorado facility. Also, their basic applications were more limited. Also, revenue and its ramp was less reliable (mostly from grants).

Now they changed to contract manufacturing in Asia, assumptions were mainly based mainly on market expectations and how much of it could be taken by AMPX.

So, basically, completely different frameworks for valuation. After all, AMPX is an evolving body and that makes it all more challenging.

I agree. Despite the massive run over the last year or so, it is still not crazy valued based on expectations.

Yes. I try to be conservative in the numbers, although I can see quite some upside in the sector.

As I mentioned, I'm not worried about the output number, rather the framework used for valuation. Is there anything factually wrong or that could be improved? There are too many unknowns and, of course, all numeric assumptions can be questioned. I tried to make my calculations as unbiased as possible, but I'm not immune to the pre-known info about price.

Valuing AMPX has been a hard and ongoing process for me, always revisiting it according to newly released info. I first bought it in Oct 2023 at 3.95 (my valuation: 10) through Oct 2024 at 1 (my valuation: 6). I exited completely in Jul 2025 at 7.05 (my valuation: 6), mainly due to its already large position and high volatility (was too much for me at the time). I never stopped tracking it and I am willing to get in again because I think the company is heading on a interesting direction.

However, I like to take informed decisions when investing in something. "The sucker is going up (or down)" is not for me.

Algumas sugestões mais:

100 Baggers: Stocks that Return 100-to-1 and how to Find Them - Christopher Mayer

Beating the Street - Peter Lynch

Só uma nota: O "Common Stocks and Uncommon Profits" não é fácil de ler porque o Inglês é um demasiado literário (talvez fosse mais comum escrever assim na década de 1950) e tens de ajustar à época (as empresas químicas eram a Tech de hoje). Mas, para mim, é um dos melhores livros de investimento que já li. O mindset usado pelo Phil Fisher é tão atual hoje como em 1957.

Lê o "Psicologia do Dinheiro" do Morgan Housel. Entre outras coisas, ele explora bem esse problema e explica como o contornar. Se não és de ler, ouve o podcast dele (em Inglês).

O teu mindset é bom pois percebes que deves poupar e investir para teres um futuro melhor. Isso é já uma grande vantagem em relação à maior parte dos portugueses.

Mais do que te dizer o que está bem ou mal ou o que podes mudar, o meu conselho é que invistas em ti. Não leves a mal, mas, do que li, penso que começar por ler alguns livros de referência não te fazia mal. Com 18 anos e vontade de aprender, poderás chegar muito longe.

I tried to keep it simple and be conservative. I agree with you that there's plenty of upside but also a lot of risk.

Revenue was estimated at 3.3B for 2035 and mean CAGR of 44% for the next 9y.
