VOLATILITY PROBABILITY

By Surly Trader

Trading is much easier when you try to stay away from the losing team. When markets are rising, do not short them. When markets are falling, be wary of catching a falling knife. To be successful at trading over the long haul, you do not have to be a winner all of the time, you just have to be a winner slightly more often then not. If you cannot achieve a probability edge, then you need to be able to “cut your losers and let your winners run”. If you are successful with both conditions, then let the money roll in.

Volatility is interesting because it is mean reverting, so we can generally say under normal times that 5% annualized volatility is low and 25% annualized volatility is high. A lot of italics in the previous statement. Due to the magnitude of the global financial recession, the extent of imbalances in current accounts, the size of government intervention and the massive debt load of developed country governments – I would call this less than a normal time. This is why I continually expect the unexpected. The risk flare can come from an earth quake, turbulence in the middle east, a missed payment by a Eurozone member, a collapse of commodity prices, a double dip in housing, an inability to raise the US debt ceiling, a spike in inflation, a subtle slowdown in the economy to stall speed, the withdrawal of government stimulus measures, or maybe something that is not even on our radar. The point is that we are in fragile times with a global economic recovery that is anything but robust. With that as a backdrop, we need to be prepared more for risk flares than a return to normalcy.

Return to normalcy or at the bottom of the range?

I read the above graph to mean that we are at the bottom of the risk level’s trading range rather than entering into normal trading volatility ranges. I fully expect to see volatility spikes return on a regular basis for the next few years, so when implied volatility is below 15 I am more of a buyer than a seller of risk protection.

If you truly believe that the economic recovery is roaring, then rationalize the drop in the level of the economic surprise index (average % outperformance of economic data versus analyst/economist forecasts) versus a somewhat euphoric march upward in equities:
