generally for a solid portfolio, I would advise to have at least 50% in blue chips as base
the rest.. u want to add more blue chips or go for mid caps or even higher risk small caps.. up to you
but basic is at least 50% blue chips
during GFC 2007, blue chips like banks/telcos are the ones that recovered
during crisis... small caps will have problems renewing debt.. banks will avoid them, investors will not pump money into them
during crisis... blue chips will be saved... can you imagine DBS/SIA/SINGTEL going down and thousands of people jobless????
