I'm a retail investor/trader with a few years' experience in the markets. Previously I relied on the abundance of free data out there, e.g. finviz, marketwatch, on and on it went, aggregating data into a sprawling folder of spreadsheets. You know what it's like. Then a couple of friends recommended Koyfin so I gave it a try, and I'm blown away by the quality vs price of the platform and the depth of data it provides. Extensive analyst coverage data, financials, earnings transcripts, filings, and not just the US either - many stocks are covered in markets such as Vietnam, Singapore and so on. I honestly couldn't be happier with this platform, highly recommended for any trader or investor who can't afford a Bloomberg terminal.
