One name seeing notable options trading is DISH Network Corp (NASDAQ:DISH). The stock is snapping back after three straight down days, last seen trading 2.3% higher at $35.98, and more than 26,000 calls have crossed already -- compared to a daily average volume of just 1,402. Most of the action has been driven by the weekly 9/27 36-strike call, where more than 21,100 contracts have traded.

Alder Biopharmaceuticals Inc (NASDAQ:ALDR) is one of the best stocks on the Street today thanks to a $2 billion buyout offer from Denmark-based Lundbeck. The shares were last seen up 83.2% at $18.43, running to fresh 52-week highs in the process. This comes just days after ALDR stock touched an all-time low of $8.39.

On the flip side, Aimmune Therapeutics Inc (NASDAQ:AIMT) is volatile again, last seen down 6.7% at $23.09, after earlier trading sharply higher. The up-and-down price action comes after a Food and Administration (FDA) panel recommended approving the company's peanut allergy drug. AIMT shares are still down 17.5% year-over-year.
