The guaranteed way to make money on the oil contango is to charter a tanker, fill 'er up! and park it in a fjord somewhere, sell the oil six months ahead and then deliver into the sale.
How can you be serious about shares and not own any resource stocks? Beats me. If there is contango in oil (I'm taking your word for that) why wouldn't you own an oil stock, Caltex even (not one I recommend)? Their oil inventory will increase in value all year.
Let me turn your question around. Do you own a diversified portfolio at the moment? do you have some nice banking shares, REITS etc? I'm guessing not.
Being serious about shares doesnt necessarily mean holding a diversified portfolio.
Diversification can often lead to
diworsification of investment performance.
Now why would me holding resource shares lead to diworsification, yet its still possible for you to profit from resource shares?
Because you understand the sector better than i do, i would be buying blind. I have absolutely no idea how to value them, especially at current prices.
Because of my lack of understanding, i might be tempted to buy resources when they are:
1) trading under the net tangible asset value; or
2) operating on an excellent CFP (cash flow per share) basis during a period when
resource prices are at depressed levels.
Neither of these conditions exist at the moment.
In regards to the current positive contango carry trade in oil. I feel this is actually a negative for oil shares in the short term (short term being a couple of years, longer term i still think peak oil is a relevant risk). I'm no expert in this area however a postive contango position (and especially one with sufficient positive contango to make arbitrage a profitable exercise) is prima facia evidence of an abundance of supply relative to demand which is bearish for oil shares.
Why dont oil companies participate in the contango trade to the full extent possible?
I have no idea, but i speculate two reasons:
1) the market wouldnt look kindly on it (ie could look like they are trying to corner the market)
2) the contango trade works best in conjuction with heavy leverage. I suspect that the market wouldnt be comfortable with oil companies taking on extreme leverage
