“Yes, you need to diversify... mix your more established growth names–e.g., your Microsofts, your Intels, your Ciscos, your Yahoos, basically, the reliable blue chip stuff–with higher-risk bets–something like an Astroturf.com, or an Iomega, or a JDS Uniphase, that will offer high-powered upside if things work out for those companies. That will give your portfolio balance, without sacrificing growth."
It's really a joke for this portfolio from some TV gurus from that time around '99, as every "blue chip" companies on the list mostly worth significant lower in '16 from their '99-00 heights: >-50%+ INTC, CSCO, YHOO (not to mentions it's on the selling block). Maybe MSFT is an exception. Those high-risk bets? more like busts: astroturf (?, never heard of it), IOM (from $100 to $3.56 when acq'd by EMC), JDSU (from ~$300 to $6 as VIAV and $25 as LITE). I really do not see what growth in such portfolio.
This just reminds me the moment that Jim Cramer and other pundits on TV urging investors to buy and hold Lehman Brothers stocks before its fall in '08 "because it's too big to fail".
