Minimize Product Costs
Actively managed mutual funds are expensive and mostly underperform their benchmarks. Index and index-like ETFs and funds are inexpensive and transparent. Index funds and ETFs are tax-efficient due to their low turnover, which also lowers transaction costs and contributes to their low expense ratios. They are built to track the indexes they are benchmarked to, eliminating negative surprises. In short, trying to guess which of the very few mutual funds that will consistently outperform the market is an expensive gamble that will probably not be successful for wealth management solutions.
Most people understand the risks involved in "having all your eggs in one basket". Many people fail to understand that simply owning a fund that tracks the S&P 500 does not make a diversified portfolio. Research has shown that a truly diversified portfolio, one that contains US stocks (large and small), international stocks (Emerging and Developed), fixed income, and real estate, in other words, one that looks like the world allocation, reduces risk (volatility) and improves returns for wealth management solutions.
Emotion is the enemy of the investor; it causes bad decisions and, inevitably, unchecked, produces costly mistakes. Sometimes these mistakes take years to recover from. Sometimes these mistakes cause losses that will never be recovered; imagine selling your equity portfolio late 2008/early 2009. Markets are impossible to predict; leaders from last year may be laggards (or worse) the next. Moving your money around according to what markets are doing doesn't work. Make a good plan, let the markets work for you, and stay the course for wealth management solutions.
