Let's say hypothetically that I have turned $50,ooo profit during the first 11.5 months of 2012. Then during the last week or two of DEC, I invest all of it back into the market where it will remain until sometime in 2013. What percentage would I be income taxed if my re-ienvestment was put into actual shares? How about if my entire re-investment was put into options contracts, is there a difference? I am currently studying tax law, but was interested in what ever it is others here would like to share about the topic.
