Once you choose to venture beyond U.S. Treasury bills, whatever you do with your money carries some risk.
Don't think you can avoid making a choice; inertia is also a decision.
It took a long time to accumulate whatever wealth you have; your financial well-being is definitely not some thing to trifle with.
For this reason, I recommend that you adopt a value-investing philosophy and either
- find an investment professional with a record of value-investment success or
- commit the requisite time and attention to investing on your own.
There are a number of issues that investors should consider in managing their portfolio.
While individual personalities and goals can influence one's trading and portfolio management techniques to some degree, sound buying, and selling strategies, appropriate diversification, and prudent hedging are of importance to all investors.
Of course, good portfolio management and trading are of no use when pursuing an inappropriate investment philosophy, they are of maximum value when employed in conjunction with a value investment approach.
