In my opinion, if we invest only in bluechip stocks issued by a trusted company, it will not necessarily be profitable both in the short and long term. because there is a lot of information that blueship shares belonging to a well-known company are not profitable so we don't get dividends, so in my opinion it would be better if we invest in a lot of bluechip stocks from several reliable and trusted companies, so that if there are some unprofitable stocks it will be closed with other stocks. profitable, What do you think?
