Assuming the lease rates are within normal bounds, is there any merit to buying a seat on CME/NYMEX/COMEX, as opposed to leasing? For example do the seats still correlate with activity in the underlying contracts, as they used to back in the days of pit trading? Any other factors to consider? At the moment the seats I'm looking at are reasonably cheap, and I'm fairly bullish on the prospects for trading volume growth in the long-term. Any advice from people who have owned seats or know much about it?
