Yes, somewhat. Not as proper as it should. But it does the job. Esp with such events as splits, mergers, renames you can see it's not a very professional setup. I've had to hack around it by adding and then nulling some assets like "emission claims". Or, in my country, dividend-tax is extracted immediately so I now hack around that by adding that tax as "fee" to ghostfolio. It works. But isn't a replacement for actual book- and portfolio-keeping.
