Show HN: Similarity Search Engine for Equities (opens in new tab)

This is cool, I quickly learned about some companies outside my region that I didn't know existed.

two other things 1. I get slightly > 1 similarity scores for exact matches for my ticker query. EX: AAPL -> 1.0000000000000007

2.It seems like it's matching exactly on ticker name. It would reduce some friction if I could search by company name as well. Then I wouldn't have to lookup the ticker every time I have a query!

It is a great idea. I think the algorithm needs some work though. Probably some guidance to the LLM could pick out attributes you could use to form a “vector” to answer questions as “what sector is this company in?”, “describe their main customer” etc. Would get expensive though perhaps.

Apparently a 10-K is a detailed financial report for US public companies https://www.investopedia.com/terms/1/10-k.asp

How is the similarity score calculated? Nike and Google have about the same similarity score relative to Apple.
