Quick background: I used to code. Studied it in school, wrote some projects, but eventually convinced myself I wasn't cut out for it. Too slow, too many bugs, imposter syndrome — the usual story. So I pivoted, ended up as an investment associate at an early-stage angel fund, and haven't written real code in years. Fast forward to now. I'm a Buffett nerd — big believer in compound interest as a mental model for life. I run compound interest calculations constantly. Not because I need to, but because watching numbers grow over 30-40 years keeps me patient when markets get wild. It's basically…

During the start of the year I was thinking how could I bet against certain stocks (in my case mainly Tesla) without using derivatives and the risks that come with them. After I had success betting on the oil price with a highly correlated investment fond, I came to the conclusion that negative correlations could be used to bet against the price of other assets. Unfortunately, it is not easy to find correlations between assets if you don't know which assets to compare in the first place. So I created a website where you can find the 10 highest and 10 lowest correlations of certain assets.

Hey everyone, we’re JJ and Mark from Double (https://double.finance). Over the past few months we’ve been working on an investing app that lets anyone design and invest in their own stock index. Start by picking one or more strategies. You can find 20+ starting points in Double that vary from direct index versions of classic ETFs (like SPY) to strategies focused on specific industries, market trends, or themes (like YC public companies).

Made this using Power BI and the Crypto Watch API. Started making this in November 2021, but never got around to publishing it, so that is the reason for the 'FOMO' in the title - probably a good thing if you 'missed out' on the crypto hype late last year. Now it serves as a way to see how much you 'saved' by not putting in money. Hope someone finds it fun!

Read the Tape gives players the same 5 S&P500 stock charts per day to predict. You select low, medium or high confidence and then call the chart UP or DOWN. It's a 1d chart which then resolves over 5 days. Alpha is scored against the Monkey Index, a basket of 11 random coin flips at low confidence which provides a tangible win/lose condition. We're two weeks in and some interesting data is being kicked up. Players like to call tops even though stonks go up- 60% of the 70 charts so far resolve higher, players' down calls have only been right 31% of the time. There's a full stats dive at…

Hi HN, A while ago I had a mildly depressing realization. Back in 2010, I had around $60k. Like a "responsible" person, I used it as a down payment on an apartment. Recently, out of curiosity, I calculated what would have happened if I had instead put that money into NVIDIA stock. I should probably add some context. For over 10 years I've worked as a developer on trading platforms and financial infrastructure. I made a rule for myself - never trade on the market. In 2015, when Bitcoin traded about 300 usd, my brother and I were talking about whether it was a bubble. He made a bold claim that…

I built this after realizing my index fund owned companies I'd never choose to support, and there was no easy way to do anything about it. Sylph lets you specify what you want to avoid (and what you want to support), then generates a diversified portfolio of individual stocks based on your priorities. Working demo, no account needed — just try it. Still early and actively building, so feedback is very welcome.

Hello - I’m the founder of Frec. We built a direct indexing product that lets you tax loss harvest the S&P 500 or the S&P Information Technology indexes for a low 0.10% fee and a minimum deposit of $20k. You can start your direct index with cash or contribute stock you already have. Our historical simulations based on 20-years of data show that we harvest ~40% of every deposit back in capital losses over a period of 5 years. I linked to a live demo account with a real $50k deposit made on Dec 5, 2023. The account shows that our trades track the S&P very closely. As of January 21, our direct…
