We have an arbitrageur in the knife biz.
the efficiency of the market
Since there seems to be a certain "investment" flavor to what this scoundrel is doing (I've waited years to be able to use "scoundrel" in a thread

), I thought I'd add one that seems to me more appropriate.
In the stock brokerage world, there is an illegal activity called "free-riding," that approximates what's happening here. Here's how it would work. In the old days, if a customer wanted to buy a stock (but didn't have any money in his account), his broker would still make the purchase for him. He would use what's called "regular way settlement." That meant that if you as a customer, gave me the broker an order to buy 1,000 shares of KnifeKnuts at 10, you would have 5 business days to come up with the $10k to pay for the trade. The customer in essence owned a stock he didn't pay for, but it was understood he would pay in the required amount of time.
Let's then say that later that afternoon, a rumor broke that Spark Industries would try to buy KnifeKnuts at $20 a share, at which point KnifeKnuts spiked up to $20 a share. The customer who entered the buy order (knowing not all takeover offers work out), then calls his broker and says "Sell all my KnifeKnuts at $20." He then has the satisfaction of knowing that he made a quick $10,000 without ever having to put up a single dime, and goes home the richer for it, right?
Wrong!
The securities regulators deem this free-riding. This person has made a quick buck without having a cent of his own money at risk...and that dog won't hunt. In this case, the customer still has to pay $10k for his initial buy order. He will then see another $20k credited to his account, netting him a quick $10k
after he has paid for his initial buy. At that point, everything is on the up and up.
Our boy here is a free rider. geegee
