Everyone expects it to go up to 100. There was strong investor sentiment and pressure to push it up all morning. Only, since everyone expects it there were more than 2x the number of calls sold as puts. Therefore, the HFT market makers with the large share of the market just wait until the big money runs out in the morning and then drops the price a dollar on negligible volume by flashing out quotes on one side of the book. Up, 100k shares traded 2 cents, up 250k shares traded 3 cents, up 50k shares traded 1 cent, down 20 cents 10k shares traded. Oh look, whoever sold those options just saved a couple million dollars. What a coincidence (not)
