comment Is there anyone still using Markowitz modern portfolio theory?
@emcor MattWolf is a practitioner. So am I ;O) "Today's methods are much more sophisticated than MPT"? Read Matt's answer.

@devon It isn't bizarre. It is a standard, and adjusted accordingly for context. Regulators use it too. Most of these answers are good, true. Read this for what happens if one totally discards MPT ;O) quant.stackexchange.com/a/15002/999

Every time I visit QuantSE I see that variable name error, "maket value". I had to edit it to MARKET. OP is Austrian, not from Boston or Yonkers.

Market was misspelled "maket", repeatedly! I thought I was in Yonkers, i.e. "mahhhhket" or Boston. I tidied MathJax and grammar, and clarified implication of neg premium: losing $. I'm sorry re my bad attitude, but OP was impudent to the other user who answered.

Contango and clearinghouse requirements are more than mere issues. As @Matthew said, if they undermine the arbitrage, they render the theoretical question pointless as currently stated. You need to determine whether the costs of contango and clearinghouse margin changes are quantifiable (seems unlikely...) and are less than the arbitrage value of the trade strategy.
