ops:In theory, it may seem so -- but in reality...the short, basic answer is basically no.ops:
cdc...I agree with the spirit of your reply but not with the specifics. Arbitrage is defined as buying a selling the same thing to earn a risk-free return. Anything else is not arbitrage, but people keep calling it as such.
Statistical arbitrage expands on the concept. Although, I agree it is a bit of a misnomer. However, I sort of agree that the expanded version of arbitrage into statistical arbitrage is a good extension of the idea in this case and the pluses of the extension outweighs the minuses.No. Arbitrage means riskless profit. It doesn't mean buying and selling the same thing. If you could buy a call option for zero, that would be considered arbitrage because you cannot lose money.
