Hi all, seeking some advice on how to start investing with Vanguard. I have decided to created an account and invest every month some amount. I would like to invest in index funds - diversified but with focus on US companies, mostly around technology, financials and medicine (my reasoning being that in Covid times these companies thrive the most). Is there an index fund people recommend? I am happy to invest long term - at least 30 years. I am from the UK. Also wondering if I should invest in the same index fund every month or try to diversify even more between several index funds and some gov bonds. Any advice for beginners would be appreciated!
