Final Ladder Positions: Simulations After Round 19

Two of the markets for final ladder positions are no longer being offered by TAB Sportsbet. Collingwood's victory over the Cats has, it seems, all but determined the destination of the minor premiership, and the Lions' last-gasp win over the Eagles has done something similar for the Spoon.

MAFL 2010 : Round 19 Results

The only conclusion that a reasonable person could reach is that the Recommended Portfolio, concerned about causing undue alarm, has determined the best way to prepare the TAB Sportsbet bookie for its eventual profitability is to do so very, very slowly.

MAFL 2010 : Round 19

It's a strange round indeed - and a pivotal one - that footy fans can look forward to this weekend.

Strange because of the number of games where the outcome appears to be a near coin-toss - a point that we'll come back to a little later in this blog - but not at all strange in terms of the activity level of the MAFL Funds.

Thank the Crows and Blame the Saints

Which teams do you think have generated the most profit for each Fund, and which have inflicted the greatest losses?

When I've looked at this question in the past I've tended to take the most obvious approach to the analysis whereby I've calculated for each team the Return on Net Funds that has resulted from wagers on that. In short, what I've done is to determine how many cents each team has added to or subtracted from the value of a particular Fund as a result of the wagering returns it has directly provided.

The weekend results for St Kilda, Fremantle, Melbourne, Richmond and West Coast were the ones that most reshaped the various ladder position markets.

MAFL 2010 : Round 18 Results

Every Fund returned a profit on the weekend's wagering, leaving the Recommended Portfolio closer to profitability at the end of the round than it's been since it slipped carelessly into unprofitability in Round 8, and inching the portfolios of MIN#002 and MIN#017 just a little closer to daylight too.
