21OVR (current price) = 37.91
21OVR.OW (current price) = 16.30
At the time of adjust the stock adjusts by 2.7*Opening Weekend. So at current prices 16.3 * 2.7 = 44.01
Hence, $6.1 arbitrage opportunity?
21OVR.OW = 100000 Short
21OVR = 37037 Long
Irrespective of what the weekend gross is, arbitrage gain = $6.1(44.01 - 37.91) * 37037 = $ 225,926
Investment = 37.91*37037 + 16.3 * 100000 = $ 3,034,073
Arbitrage Returns = 7.4463%
- Commission = 2%
Riskless Profit = 5.4463%
Does that make sense? Is there any flaw in the logic?
