How we're different
The investment industry tends to silo its recommendations, such as you need stocks for growth and bonds for income. Instead, almost every portfolio needs wide diversification to safely achieve your objectives, because you never know what asset class will perform well.
It is also important to know the history of performance of what you are investing in and how well it has done over long periods, through recessions, interest rate increases, inflation, bear markets, etc.
This is my specialty. I have been an investment writer and researcher since I began in the industry and am most interested in finding the best custom fit.
If you are interested, please contact me, and we can evaluate your goals to determine if there is a way I may help you. There is no charge for this initial evaluation.
