speaking as the child of a financial advisor, i gleaned a few bits of advice from my dad through the years. the biggest one, though, is that he hardly ever advises his clients to invest in tech stocks-they are wildly unpredictable and still have not stabilized since the dot.com boom, at least not for long term-investing. for that more traditional companies are still the best bet.
and it makes sense. with the exception of an enron-type scandal, a company that deals in utilities or manufacturing won't typically see gigantic leaps forwards and backwards like techs will, because those industries are not innovating/changing as fast as technology companies do.
