Mosaic attracts unusual put activity

MOS is 2.5 percent to $48.78 today in midday trading as shares remain in their range of the last week but climb off a two-year low of $44.43 reached on June 4. The fertilizer company has been trending lower from the $60 level in the last two months and was trading above $70 as recently as September.
A trader bought 4,000 June 55 puts for $6.50 against open interest of 3 contracts, then sold two blocks of 2,000 September 55 puts for $7.85 and $7.90 in the next minute, according to optionMONSTER's systems. The open interest at the latter strike was 1,517 contracts.
This short calendar spread is a bit odd because it is in the money and using options that finish trading today. On Monday the trader will simply have the September 55 short puts unless he or she buys more near-term puts to hedge the position. (See our Education section)
