Hi guys, just have some basic options questions I was hoping you could help out on.. 1. Should I never worry about how many options I am buying/selling, and whether that will effect me down the road as I try to sell and buy them back because market markers have to provide a liquid market? For example, I am worried about buying some vertical spreads as it seems like in even some pretty heavy volume stocks and ETFs, if I wanted to take on a $3,000(this is hypothetical as I am still in paper money) vertical spread. I could end up owning more volume then there is trading in the day. And sometimes own maybe a 8th of open interest, is this a problem? 2. As a follow up to the above question, does it make sense with spread positions to widen out your strikes. For instance, on the SKF I could buy a Mar 150/155 put spread that is trading at $2.00(4/10 ratio) or I could buy a Mar 150/160 put spread that is trading at $4.00(4/10 ratio again). With the latter spread I have a better break even price (150/160 is $156.00 and 150/155 is 153.00) pay half as much in commissions both ways, and hopefully could sell the spread a little quicker since I would have less options to move. Is there a downside that I am not seeing to this? 3. If you can tell by an optionâs pricing that the market is already expecting a price decline, would you be better of shorting a stock then buying the options if you believe the stock will decline since a lot of the downside is already priced into the options(same theory applies to the upside as well)? 4. And just to check that I am on the right path, when you believe that a stock has upside potential but has a super high IV due to a recent decline, it would make more sense to buy the stock alone or the vertical call spreads right due to the vol. skew the calls will suffer from? 5. And also this is just somewhat of a philosophical question that probably has no right answer for all investors but I would be interested to see what you guys have to say. Do you believe that it would be better to master one stock/index/ or etf and trade all kinds of options strategies within that stock that you know so well, or would it be better to master a specific options strategy and try and trade that across all stocks and markets, or would you just say that it is better to have a combination of the two? Thanks for all the answers you guys have been providing on this board as I have been reading just about every thread and is has certainly helped along with everything else I am doing.
