In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are often denoted by Greek letters.

感谢您的反馈，我们会尽快进行适当修改！This Demonstration shows the price and &Greeks& for binary call and put options together with the corresponding vanilla European option as a function of underlying spot price (the option strike price
is set to 100). The controls let you explore the effect of the model's input parameters.

Binary options are a type of exotic option for which the payoff is determined by whether the final stock price
is greater or less than the strike price . A binary call option pays out if , while a binary put option pays out for . In this Demonstration we set the payoff amount to be the strike price . As this Demonstration shows, the price of binary options—and its derivative with respect to the various model inputs—displays some interesting differences compared to the more well-known behavior of European options. For example, the &delta& of at-the-money binary options becomes very large close to expiry, which in practice makes such options difficult to hedge (Snapshot 1).Another example is the &theta& of binary calls, which can be positive when the option is &in the money& (that is, when spot
strike); by contrast, the theta of European options is always negative (Snapshot 2).J. C. Hull, Options, Futures, and Other Derivatives, Upper Saddle Creek, NY: Prentice Hall, 2006.

The mathematical characteristics of the Black-Scholes model are named after the greek letters used to represent them in equations. These are known as the Option Greeks. The 5 Option Greeks measure the sensitivity of the price of stock options in relation to 4 Changes in the underlying stock price, interest rate, volatility, time decay.
Option Greeks allow option traders to objectively calculate changes in the value of the option contracts in their portfolio with changes in the factors that affects the value of stock options. The ability to mathematically calculate these changes gives option traders the ability to hedge their portfolio or to construct positions with specific risk/reward profiles. This alone makes knowing the Option Greeks priceless in options trading.
Delta measures the sensitivity of an option's theoretical value to a change in the price of the underlying asset. It is normally represented as a number between minus one and one, and it indicates how much the value of an option should change when the price of the underlying stock changes by one unit.
Puts have a negative delta because they have what is called a "negative...

Characteristics of Options
r? Definitions and Positions:
- A Call Option gives its owner for a specified time the right to purchase an underlying good at a specified price (= exercise price or
strike price)
- A Put Option gives its owner for a specified time the right to sell an
underlying good at a specified price (= exercise/strike price)
- An American Option permits the owner to exercise (=buy/sell
underlying) at any time before or at expiration.
A European Option can be exercised only at expiration
- There are always two positions in an option contract:
BUYER and SELLER.
The buyer of an option has to pay a “price”, the so-called option premium. The seller of an option receives the option premium.
The option premium is an immediate expense for the buyer and an immediate return for the seller, whether or not the owner (=buyer) ever
exercises the option
- Four basic positions in options:
(1) Buying a Call à? Long Call
(2) Selling a Call à? Short Call
(3) Buying a Put à? Long Put
(4) Selling a Put à? Short Put
Buyer (Long)
Seller (Short)
- Obligation to deliver the
underlying, if buyer
exercises the option

...Question 1: (three pages maximum)
Homer in 750 B.C. wrote The Iliad and The Odyssey. Hesiod another Greek poet wrote Works and Days in 700 B.C. Compare and Contrast both authors as it relates to Greek Society.
Homer, known as the great epic poet of ancient Greece, though when he lived is unknown, Herodotus estimates that he lived 400 years before his own time, which would place him at around 850 B.C. Others ancient sources puts him nearer to the supposed time
of the Trojan War, in the early 12th century BC. However, most modern researchers place Homer in the 7th or 8th centuries BC. Of all is works, his greatest contribution can be said to that of Literature i.e. considering that about fifty percent speeches, provided models in persuasive speaking and writing (one of the many Greek influence on the western world). Two particular works that stood out being The Iliad and The Odyssey. For Homer, these works were written in his point of view of the Gods illustrating how men were pawns to their will. Equally, however, Homer through these epic stories, showed the resilience of men to overcome struggles in their achievement of power, glory and heroism i.e. the Homeric approach “doer of great deeds”.
Homer’s The Iliad gives account for the ten year battle between Greece (the Greek King Agamemnon) and Troy (Priam, the Trojan King). This epic story tells of a war started as a result to Priam’s son Paris who took with him on...

...Examples of Futures and
Options Contracts – Speculation and Hedging
As Dr. Cogley said in class the other day, sometimes futures contracts and options are
hard to wrap your head around until you see them a few times. So I’ve written up some
examples similar to those Dr. Cogley did in lecture, with a little more explanation about
how we get the results that we do. But before we jump into that, we need to revisit our
1. Forward contract: A buyer and a
seller agree to a specific price/quantity exchange
sometime in the future. Forward contracts are done between individuals (no
intermediary), so all financial risk is born by those in the contract, which may
result in some sort of risk premium factor being included.
2. Futures contract: Similar to forward contracts, but sold via exchange markets
which act as intermediaries. By charging small transaction costs, the
intermediaries cover possible default by either party, meaning those in the
transaction no longer have to concern themselves with default risk.
3. Options contract: Similar to futures contracts, but without the binding effect – you
pay a premium now to have the right to buy or sell in the future, but you don’t
have to if you decide you don’t want to.
a. Call vs. put: call is the option to buy a security in the future at a set price,
whereas a put is an option to sell at a set price.
b. European vs. American: European options...
...Option Valuation
Chapter 21
Intrinsic and Time Value
intrinsic value of in-the-money options = the payoff that could be obtained from the immediate exercise of the option
for a call option: stock price – exercise price for a put option: exercise price – stock price
the intrinsic value for out-the-money or at-themoney options is equal to 0 time value of an option = difference
between actual call price and intrinsic value as time approaches expiration date, time value goes to zero
Determinants of Option Values
Call + – + + + – Put – + + + – +
Stock price Exercise price Volatility of stock price Time to expiration Interest rate Dividend rate of stock
Binomial Option Pricing
consider a stock that currently sells at S0 the price an either increase by a factor u or fall by a factor d (probabilities are irrelevant) consider a call with exercise price X such that dS0 & X & uS0 hence, the evolution of the price and of the call option value is uS0 Cu = (uS0 – X) C S0 dS0 Cd = 0
Binomial Option Pricing (cont.)

...Greek Colonisation in the Archaic Period
Rachel So-Mahng Truong Yr11 Ancient History
The city states of Cyrene and Sicily were founded by the Greeks in ancient times, circa 7th century BC. These colonisations were due to the land hunger, need for trade, overpopulation and political and civil disputes that were prevalent during the time period, making it necessary to colonise other parts of the Mediterranean such as the Italian islands and northern Africa.
This colonisation also led to changes in class structure, trade practices, lifestyles, agriculture and the spread of Greek ideas..
Agriculture was always a huge foundation of the ancient Greek economy with nearly 80% of the population being involved with its progression. Therefore, it was no surprise when near the beginning of the Greek people began to realize the considerable lack of arable land in the Greek Peninsula. In addition to this lack of land, the majority of suitable farmland was owned by rich aristocrats who passed down their lands through primogeniture, leaving poorer peoples and their own younger sons in shortage. The lack of farming area and the rapidly growing population made it urgently necessary to relocate to other lands.
The 7th century BC in Greece was usually rife with political and civil discontent, mostly due to disputes over land, resources and the aristocracy. There was often fierce...
1. The early Greek city-state was divided into four social classes and they were: eupatrids, agroikoi, demiourgoi and the slaves. Eupatrids (“sons of noble fathers”) are citizens with full legal
free adult men born legitimately of citizen of parents. They had the right to vote, be elected into office, bear arms, and the obligation to serve when at war. Agroikoi are the farmers, which had no formal political rights but full legal
rights. Demiourgoi are the “public workers” in which chose to reside elsewhere (the metoikoi); they are free-born and possesses full rights in their place of origin and full legal rights but no political rights in their place of residence. They could not vote, could not be elected to office, could not bear arms and could not serve in war. The slaves were under the full possession of their owner with no privileges other what their owner would grant at will. The advantage of belonging to one class to another is having political and economical advantages.
2. The economical development complicated the traditional class system by increasing economic gap. The rich with land kept getting richer and the poor reduced to selling land, sharecropping or debt slavery. Number of “Thes” increased, contributing to large rise in “thetic” class.
On top of that, due to creation of hopla (a new kind of heavy shield) and hoplite, the agrikoi and demiougoi began to break into the aristocratic ranks for larger...
...The oracles always had a hidden meaning behind the surface one
* Meaning of the oracle
* Character is destined
* Oedipus even if he is told what he is going to do
* He still does it – because he fails to understand some of the forces that move him
* In Oedipus’ constant challenges to this voices like the Delphic oracle, like Tyresius
* Sophicles pointing to other sources of knowledge that have better insight into deep human realities
poetry itself (tries to decypher motives for war)
* Prophecy
* Like intoxication (getting out of your mind)
* Glimpse of natural world in different state
6: Socrates for example was very critical of many aspects of the Greek enlightenment (we can see this in the critic of the sophis)
* Sophists lack self knowledge
* Oedipus lacks insight into the deeper realities of his inner self
* Maybe sophicles is suggesting that the way out of being moved by forces which we don’t understand is to gain self-knowledge and to free ourselves in this way
* Self-knowledge is the road to freeing...
