But, I have always had one problem, and that is the ending. Now, it is a masterpiece of editing and directing. You have no trouble keeping up with what is happening, how the plan is working, and the pacing of the scene really ratchets up the tension, even if, like me, you are relatively clueless about how the stock market works. The scene relies on the characters' actions and reactions to convey what is happening.
But I wanted to know EXACTLY what was happening, how exactly this scheme worked. One of the guys who sometimes hangs out on line does know the stock market. He taught me about futures trading and how it influenced gas prices a couple of years ago. Since the climax hinges on futures trading, I figured he would know. He did. So, as a public service, here is the ending demystified.
The key to everything is to understand how the futures market works. The way capitalism works is you make something and sell it to make a profit. When you are dealing with finite resources, like say, printing comic books to sell, it is easy to build business plans with this, because the price doesn't fluctuate. But when you are building a business based on natural resources, you have to take into account availability. Will there be a big strike of gold here? Will the current oil well run dry? It becomes impossible to set prices and plan around them.
This is where the futures market comes in. The person selling the future is basically saying that he will sell you X amount of whatever and price Y. Now, if the stuff he is selling comes in at a lower price than he is selling, he makes a profit. If it comes in at a higher price, he loses money. Basically, the seller is assuming the financial risk, and the seller is gambling that he can outguess supply and demand. This is why gas prices shot up so high a couple of years ago. With China subsidizing the price of oil for its country, futures traders were able to charge whatever they wanted, and they got it. It wasn't until China said they wouldn't do it anymore that the futures traders started losing money, forcing the price down, because they could no longer get whatever they were charging.
Everybody with me so far? That's good!
Now, there is a key difference between gas and concentrated frozen orange juice, the lynchpin of the scheme in the movie. Gas prices at the pump can be adjusted almost instantly. I've been at the gas station and seen the price go up while I was in the middle of gassing up (because I started pumping before the price changed, I got the 5 cent cheaper price). FCOJ, the price is constant, regardless of how much the futures prices fluctuate. So, whatever happens, you are stuck and really need to plan in advance. In case you are wondering why futures traders have ulcers, hypertension, hair loss, and heart attacks relatively early in life.
Now, one other thing to keep in mind is the concept of the margin call. This happens after the scheme succeeds. Buying on margin means you are putting up collateral. Whatever happens, the money is guaranteed to be transfered to whoever is supposed to get it. This enables you to start trading without having to pay everything up front.
Okay, the wheels are set in motion with a phony crop report. There's an orange harvest coming up. It's a seasonal crop, so everyone wants to guess this one right -- there isn't a chance to do it over for a whole other year. Now, if the crop of oranges is damaged by weather, that means fewer resources, and the people who have the oranges can charge more from them. Who else are you going to get them from? So, the question was, was the weather going to ruin it? The answer, according to the real report, was no. So the price would stay the same. However, the phony report made the Dukes think the available resources would get smaller. So they were buying up FCOJ futures, certain they would turn a profit, no matter how much they spent.
So, the climax starts. Winthorpe and Valentine wait for the price to go up, and start selling futures. Now, as it is the futures market, they are free to sell what they don't already have. As far as the rules of the exchange are concerned, their only obligation is, when trading concludes, they provide whatever they have promised to sell. They provide the merch, not the price. So, when they buy back the futures at the end, they are doing it for a fraction of what they sold for. They can't help but make a huge profit with what's left over after all the transactions are completed. Because the Dukes bought so high, they could only sell when the price is going down, losing every step of the way. When trading concluded, they had to provide all the merch they promised at that price. The margin the Dukes had wasn't enough to cover the money they owed, and they had to either pay more into the margin fund or get out. They didn't have enough money, and were forced out.
Now, I understand there have been some adjustments to trading rules since then to cut down on insider trading. So this scheme wouldn't work this day in age. But at the time, it was perfectly feasible. And that's how the whole thing worked.
