Once a portfolio has been designed and implemented, what happens next? Studies show that asset mixes as well as proper rebalancing are keys to successful ROI. However, a portfolio based on certain historical statistical and financial analysis during a specific period in the past may only be valid for an indeterminate length of time.

Be Cautions When Considering Backtests of a Proposed Investment Strategy
When evaluating new investment portfolios, the use of backtesting to justify portfolio construction and trading methods is a common marketing tool among many firms.
