P.S. I think several centralized exchanges offer access to stock markets but I rather use a DEX.
I saw some DEX that offers tokenized stocks that you are looking for when I check the coinmarketcap tokenized stocks category. I can’t vouch for the reputation of these project but you can check below some DEX that offers tokenized stocks. Do your own research regarding the project.

Let's however not call them stocks. Even when those sites do, they are not speaking the whole truth
They are not "stocks", they are called synthetics, meaning that they represent the value of the stock.
When you buy synthetics, you are not owning a stock, you won't have any rights that come with it. Just the promise of the value you will get by buying / selling it.
