lying instrument. Upon finding such discrepancies, the trader attempts to take
|
||||
advantage by constructing a more or less neutral position, preferring not to predict
|
||||
price so much, but rather attempting to predict volatility.
|
||||
Most volatility traders attempt to buy volatility rather than sell it, for the rea
|
||||
sons that the strategies inherent in doing so have limited risk and large potential
|
||||
rewards, and don't require one to monitor them continuously. If one owns a straddle,
|
||||
any major market movements resulting in gaps in prices are a benefit. Hence, mon
|
||||
itoring of positions as little as just once a day is sufficient, a fact that means that the
|
||||
volatility buyer can have a life apart from watching a trading screen all day long. In
|
||||
addition, volatility buyers of stock options can avail themselves of the chaotic move
|
||||
ments that stocks can make, taking advantage of the occasional fat tail movements.
|
||||
However, since volatility and prices are so unstable, one cannot predict their
|
||||
movements with any certainty. The vagaries of historical volatility as compared to
|
||||
implied volatility, the differences between the implied volatility of short- and long
|
||||
term options, and the difficulty in predicting stock price distributions all compli
|
||||
cate the process of predicting volatility. Hence, volatility trading is not a "lock," but
|
||||
its practitioners normally believe that it is by far the best approach to theoretical
|
||||
option trading available today. Moreover, most option professionals primarily trade
|
||||
volatility rather than directional positions.
