If you have heard it once, you have heard it a thousand times: 'don't put all of your eggs in one basket'. The investment market is volatile. You could be riding high one minute with mining investments, then the next, your fortune tumbles because an earthquake wipes out a sector of the mining industry.

Diversifying your investment portfolio is critical if you want steady gains. With so many investment options, having a diversified portfolio leaves you with lots of choices. Diversifying doesn't mean compromising. You can still focus on ethical investments, just hold them in different industries: ethical bonds, ethical money markets, ethical properties, ethical energy.

Even though this example shows all of your investments are in ethical markets, the markets are all different, so theoretically, if one does badly, the others will not be affected.

There will always be swings and changes in investments: an investment that has brought in great returns may one day turn sour, but other investments will be going up at the same time as one goes down. Spread your risk, and your investment funds, and you should be set to weather any storm.
