Ok another rookie question to the options traders. I have seen many references to the fact that MMs attempt to make the most widley held stock options worthless by walking the actual stock to the most logical price for this. 1. 1st of all is this really true or is it BS from traders who blame MMs for everything that moves against them. 2. If it is true is it only the NAZ listed MMs or do NYSE specialists play this game too. 3. Can anyone point me to a website or book that will explain in the best terms how I would compute the most likely target price if this is true. Obviously I can figure out how to make some options worthless vs. the stock. I have a few guesses as to possible formulas to make the best case scenario for MMs on option expiration day also. I'm interested in this information so I'm better equipped for tommorro and then the next expire date, but for an example: I hold a very happy short position on REI currently which closed at $14.50 today. I see various levels of open interest at various strike prices here: http://finance.yahoo.com/q?s=REI&d=o Now since this is an NYSE stock I'll assume (maybe stupidly) that the specialist doesn't have any interest or care about what happens to the folks dealing the options. Right? He simply marches the price around based on buy/sell orders coming in. I realize I know very little about options so please don't state that as I'm aware of it. I understand the concept of options but that's it. Any insight greatly appreciated.
