I am an individual investor nearing retirement (within the next 10 years). My portfolio is diversified among a 401k, an IRA, and a retail trading account. I manage my 401k by tactically rotating between a varying mix of stock and bond mutual funds using momentum and trend-following strategies.. My IRA is managed by an outside firm who maintains it in a balance of dividend-paying stocks and ETFs, with an overlay of covered-call strategies. A portion is also maintained in cash to take advantages of opportunities as they arise. I manage my retail trading account trading options based on overall market volatility using underlying vehicles such as VIX, VXX, XIV, and SVXY.
