Waters Corp (WAT) was mentioned intraday Wednesday, with unusual call action and it continued throughout the day with shares closing near highs, up 1.6% while IV spiked 13% higher. More than 6,600 calls traded, which is 35X average, and comes after the recent takeover of Millipore has many thinking Waters could be next as a filtration play. The March 65/70 and April 70 calls attracted buyers, mostly offer side on the 100+ contract orders. Shares trade 15.4X earnings and 18.8X cash flow. The recent breakout has shares eyeing a move to 2008 highs around $70, although a takeover would likely fetch a 25% or more premium.

Norfolk Southern (NSC) is often considered the best managed rail company, but the stock is not at 52 week highs like it’s counterparts Union Pacific (UNP) and Kansas City Southern (KSU). That could change with a break of $55, which would target a move to $60. Option traders were decisively bullish Tuesday, with 4,425 calls trading, 3X average, and 90% offer side buys. The April and June $55 calls both saw buyers, with 2,800 in April $55’s changed hands. Shares trade 13.2X earnings and 18X cash value, and recently were raised to Overweight at Barclays with a $62 target. Recent improvements in pricing, shipping volumes, and improved outlook for coal were cited as reasons for the upgrade.

Quest Diagnostics (DGX) had a large straddle sell at 3:15pm Tuesday, as 2,000 March 55 straddles were sold for $3.25, believing shares are trapped between $51.75 and $58.25 through March. That puts shares between a gap as resistance and a double bottom support level, so a fairly high probability trade, although the value is not all that great as IV is already depressed at 22%, near 52 week lows. At a fair valuation of 12X earnings and 13.5X cash flow, and no near term catalysts, the trade might make some sense.

Shares were hanging around the 200 day EMA and are breaking out of a bullish flag today, and also out of a longer term downtrend. Earnings are scheduled for 2/17 and large cap Biotech stocks have done well so far this earnings season with Gilead (GILD) and Amgen (AMGN) reporting solid forecasts. Genzyme has a PDUFA date set for June 17th for Lumizyme in Pompe disease. This trader may be looking for an early response from the FDA or is just playing the technical strength.

Merck (MRK) with a large trade Thursday, as 10,000 of the April $40 calls are sold and 10,000 of the January 2011 $40 calls are bought for a $1.04 calendar call spread. There has also been the sale of around 10,000 February $40 calls today, so the move higher may be slow, but looking for Merck to be above $40 next year, and look for volatility to come down.
