Survey the damage
How did your portfolio hold up under the strain of a market crash? Did your overall account balance fall more than the overall market? This may be indicative of a portfolio that is too aggressive for your goals.
Or, there may be a specific investment that is upending your otherwise stable portfolio.
Conversely, if your portfolio weathers the storm better than anticipated, you should zero in on what investments were the most resilient so you can formulate a strategy can help you withstand future market volatility.
