Every downturn in the market that experts cite always came back base the statement on long term historical gains and losses and assume you would never cash out of the market (because it would be stupid to pull out of the market in their opinion). Do they really have your best interest at heart here? Aren't they assuming that the risk of loss of your principal is acceptable to you if you need to cash out of the market for some reason prematurely. Everyone's risk tolerance is not the same, and the perceived risk of loss of principal can be stressful to anyone to decide. Don't let greed or fear dictate your decision making or thinking.
Diversify and understand risk. Talk to a professionally licensed insurance and annuity agent that is legally bound to look out for your best interest in determining suitability of risk. The managed fund brokers/dealers will make you think that accepting some level of risk to achieve this incredibly better gain is far smarter than just leaving principal in a cash value life insurance plan or fixed rate annuity contract, or certificate of deposit. But it is your money. Understand the risk and your levels of risk tolerance to feel good about what you are doing with your money. Call 301-892-0207 for assistance in selecting a life insurance or annuity agent that I would trust in your state.
