There isn't any right or wrong answer I guess....... after my first 2yrs of investing in shares via HALIFAX sharebuilder I think I hold shares in at least 50 different companies bought between £5 to £20 a pop las time I tried counting them...... some worked out (one hit 250% in profit today last time I looked), while others bummed out big time (over 80% loss).This is my favourite article in on investing in shares:
http://www.fool.co.uk/school/2006/sch060130.htmAnd further on, where it tells you about some of the world's greatest investors (e.g. Warren Buffett, Benjamin Graham, etc). Here's the page on Warren Buffett:
http://www.fool.co.uk/school/2005/sch050930.htmAnd here's a quote from him on this:"If you are a know-something investor, able to understand business economics and to find five to ten sensibly-priced companies that possess important long-term competitive advantages, conventional diversification makes no sense for you. It is apt simply to hurt your results and increase your risk. I cannot understand why an investor of that sort elects to put money into a business that is his 20th favourite rather than simply adding that money to his top choices - the businesses he understands best and that present the least risk, along with the greatest profit potential. In the words of the prophet Mae West: 'Too much of a good thing can be wonderful.'"So, going by that (and personal experience) I'd say try sticking with shares in no more than 10 different companies & gradually build your holding in them over time.... perhaps 5 stable & established big name companies for getting good dividend payments (such as RBS.L, LLOY.L, HBOS.L, SVT.L, KEL.L)... the rest for trying to get good growth out of them (research them at
