Document(page_content='Hello everyone,\n\nI would really like to invest in an ETF that follows spy or another big index, as I think this form of investment suits me best. \n\nThe problem is, that I live in Denmark where ETFs and funds are taxed annually on unrealised gains at quite a steep rate. This means that an ETF growing say 10% per year will only grow about 6%, which really ruins the long term effects of compounding interest.\n\nHowever stocks are only taxed on realised gains which is why they look more interesting to hold long term.\n\nI do not like the lack of diversification this brings, as I am looking to spend tonnes of time picking the right long term stocks.\n\nIt would be ideal to find a few stocks that over the long term somewhat follows the indexes. Does anyone have suggestions?\n\nI have looked at Nasdaq Inc. which quite closely follows Nasdaq 100. \n\nI really appreciate any help.', metadata={'post_subreddit': 'r/investing', 'post_category': 'new', 'post_title': 'Stocks that track an index', 'post_score': 7, 'post_id': '130auvj', 'post_url': 'https://www.reddit.com/r/investing/comments/130auvj/stocks_that_track_an_index/', 'post_author': Redditor(name='LeAlbertP')})]
