try to never predict the stock market as a whole but the cycles show this as a down year (BIG down). this advice is worth less than you paid for it if past predicts future. I would start by identifying stocks that show a distinct tendency to be weak in the first half of the year and try sales there. That way, you have a seasonality chance as well as a general market chance. Ideally, both hit and you get the real high volatility. I sometimes had some luck buying puts in Feb/Mch. with May/June strikes. around that time frame. If weakness is to come in the second half, you'd try the same seasonals with other issues (that is, What shows weakness in the fall, generally). Ideally, BOTH seasonals work.
the gbp should top the first 3 days of the new year (Wed., Thurs., Fri.) around 167 + or -. More of a medium time turn. Not a likely re-buy any time soon.
everything subject to change without notice, of course.
