If you're not seeing a stock on Zoya it might be in a market we don't have support for yet or it might have recently gone public, a new IPO.
We're always adding new stocks and funds to Zoya and are actively working on expanding to more markets.
In general, newly listed companies can take a couple of months to start appearing in Zoya. If the company doing IPO is considered important for the investment community and has released historical annual reports for us to capture info, then we would add it to the database immediately. Otherwise, we would likely wait until they release their first annual report. Factors such as the size of the company, liquidity, and index inclusion will also play an important role when we prioritize which companies to update first. That said, we hope to expedite this process significantly in the coming months.
