Definition of Uncovered call
A short call option position in which the writer does not own shares of underlying stock
represented by his option contracts. Also called a "naked" call, it is much riskier for the writer than a covered
call, where the writer owns the underlying stock. If the buyer of a call exercises the option to call, the writer
would be forced to buy the stock at market price.
The sum of cash, accounts receivable, and short-term marketable
investments (if any) is divided by
total current liabilities to compute this ratio. Suppose that the short-term
creditors were to pounce on a business and not agree to roll over the
debts owed to them by the business. In this rather extreme scenario, the
acid test ratio reveals whether its cash and near-cash assets are enough
to pay its short-term current liabilities. This ratio is an extreme test that
is not likely to be imposed on a business unless it is in financial straits.
This ratio is quite relevant when a business is in a liquidation situation
or bankruptcy proceedings.

Put-call parity relationship
The relationship between the price of a put and the price of a call on the same

exercise price. The call value equals C=S+P-PV(k).
A short put option position in which the writer does not have a corresponding short stock
position or has not deposited, in a cash account, cash or cash equivalents equal to the exercise value of the
put. Also called "naked" puts, the writer has pledged to buy the stock at a certain price if the buyer of the
options chooses to exercise it. The nature of uncovered options means the writer's risk is unlimited.
Yield to call
The percentage rate of a bond or note, if you were to buy and hold the security until the call date.
This yield is valid only if the security is called prior to maturity. Generally bonds are callable over several
years and normally are called at a slight premium. The calculation of yield to call is based on the coupon rate,
length of time to the call and the market price.
