Hi there,
Essentially the question you are asking relates to a concentrated vs. diversified investment. Obviously one is FAR riskier than the other. ETFs have moved on in this country and you can now buy ETFs that provide specific exposure and also exposure to particular strategies (e.g. high yield such as YMAX for example).
For a long term buy and hold it will always be safer to invest in a portfolio of assets rather than a single bet!
