My suggestion is having a right diversification can help generates a very good return. When I say "right", it means it should be diversification of best of one or two in each category in each industry or each group, but not random picks. Say for instance, In finance industry, pick 2/3 best stocks (best one for large cap and best one for midcap)/best small cap), In transportation industry, pick 1 best stock. In technology, pick 1 and so on. That's what I call it a "right diversification." And it's always wise to diversify the industries.
%% Sounds right; but since DOW transports have changed so much since 1929-33, i may find a more suitable sector than that for me.I guess, now that Mr Buffet diversified in to tech stocks like AAPL; i guess its OK to diversify......
====i guess its OK to diversify......===== diversification is no substitution for the working method those who have it - concentrate those who don't - can diversify (put a bandage on the otherwise exposed ass) Leo Tolstoy once said:"In the life you are either strong or you are asleep"
%% Thats a key to strong health; proper sleep.That's right. NOT sure if it helps GE,or DB but should help most. NOT a prediction
Best diversification? That would be the one when you take a comparison of all picked stocks with its competitor (stocks) fundamentally/ technically. Growth of revenue, debt, dividend plays the major role.
It's a phrase used by advisors to churn accounts. And make others appear like they know what they're talking about. Many BRK investors own 1 stock, and became wealthy. Warren has something to say about the topic.
