#assignment NTGR

Back in July I sold a Dec. NTGR 55 put, rolled it to January, then February, then March. It had become an NS option. I was assigned and also received 198 shares of ARLO, a spin-off. I was assigned at 41.25, even though it was a 55 put. ARLO is going for 3.83, but TDA says I was assigned at 6.93. I’m down about $500 on the two positions. Always something new.
