What name is given to a value such as this?
"This is called ""change"" or ""movement"" - the change (in points or percentage) from the last closing value. You can read more about the ticker tape on Investopedia, the format you're referring to comes from there."
"All else being equal, you should look for more volatile (riskier) stocks. Technically, it was all time value - the entire value of an ""out of the money"" option is time value.   What's confusing is that time value is affected by numerous variables, only one of which is time. The reason volatility is the one to look at is that all the rest are likely already intuitive to you, or are too minor an influence to worry about: Current risk-free interest rates and a stock's dividend payout during the life of the option affect the value of the call, but are usually minor infulences.   (Higher interest rates makes call values higher, and higher dividend yield makes call values lower.) Longer time to expiration will increase the value of the call, but you're pretty likely already focused on that. The strike price's proximity to the current price affects the call's value - agreeing to sell a stock 5% above current levels will pay more than agreeing to sell it 10% above current levels - but again, this is likely obvious to you. Volatility, or the percent by which the stock is likely to move up or down on a given day, is almost certainly the variable that's not already obvious. Stocks that jump all over the place have higher volatility than those that move more predictably.     The reason that options (calls and puts) cost more on higher volatility names is that options' payout is asymmetrical.  In the case of calls, the option holder gets all the upside, but none of the downside, other than what they paid for the opotion.     If one stock goes up or down $5 every day, and another goes up or down $20 every day and you could pay some fixed amount to get that stock's upside, but not have any exposure to its downside, other than that fixed amount, you'd pay more for the one that pays you $20 or $0 than you would for the one that pays you $5 or $0.    That's why higher volatility (meaning larger daily moves) makes optimum prices higher." I'm calculating that to about a 7% apr, which given loan rates available today seems a bit high.   I wouldn't get too caught up on what that equates to over the life of the loan.  There are a lot of forces in play over a 30 year period, namely the time value of money.  30 years from now a dollar will be less valuable in real terms due to the forces of inflation.  At 2% per year in inflation today's $1 will be worth about $0.55 in 30 years. "An option is a financial instrument instrument that gives you the right, but not the obligation, to do some transaction in the future at a given price. An employee stock option is a kind of ""call option"" -- it gives you the right, but not the obligation, to buy the stock at a certain price (the ""exercise price"", usually set as the price of the stock when the option was granted). The idea is that you would ""exercise"" the option (buy the stock at the given price as provided by the option), if the value of the stock is higher than the exercise price, and not if it is lower. The option is gifted to you. But that does not mean you get any stock. If and when you choose to exercise the option, you would buy the stock with your own money. At what time you can exercise the option (and how many shares you can exercise at a given time) will be specified in the agreement. Usually, you can only exercise a particular share after it has ""vested"" (according to some vesting schedule), and you lose the ability to exercise after you no longer work for the company (plus perhaps a grace period), or after the option expires." I don't see how it goes any other way. This is a company for which their entire value proposition is rooted in data security and integrity. That shown to be a farce, what's left? Also, there are direct competitors who weren't affected, which means they aren't uniquely positioned to rebound.  It's not unlike Arthur Andersen. Once your name is tarnished in that kind of an industry, there's not really a road back. "I'd personally display ""n/a"" The only other answer that makes sense to me other is ""infinity"" (phone keyboard doesn't allow me to input the symbol). This would at least allow you to show direction by using positive and negative  infinity and mathematical as the the initial value approaches zero the percentage change approaches infinity which is the closet you can get to a meaningful value" Unless stated otherwise, these terms apply to all bonds. The par value or face value of a bond refers to the value of the bond when it's redeemed at maturity. A bond with a par value of $10,000 simply means that if you purchase the bond and hold it until the maturity date specified in the contract, you receive $10,000.  The purchase price, however, is exactly that: it's what you paid for the bond. Bonds may sell below, at, or above par. Continuing the example from above, if you paid $9,800 for a bought a bond with a $10,000 par value, you bought the bond below par. A bond selling below par is said to be selling at a discount. For bonds selling above bar, they're selling at a premium. If the purchase price and the par value are the same, the bond is selling at par. These terms apply to callable bonds only, which are bond contracts that allow the issuer of the bond (in the case of municipal bonds, the institution or agency who created the contract) to buy back from bond holders at a given date (the call date) and at a given price (the call price) before the bond reaches maturity and pays the holder the full par value.  Yes, the coupon rate is essentially the interest paid. It's usually represented as a percent of the par value, so if the $10,000 in the example above had a 5% coupon rate, this means that it paid out 0.05 * 10,000 = $500 each year. Usually, this payment is made as two semi-annual payments of $250. Some bonds are zero-coupon bonds, which means exactly what you would think; they don't make any coupon payments. U.S. Treasury Bills are one example of a zero-coupon bond. All of these factors are linked, because the coupon rate, callable provisions, and par value, along with the overall economic environment, can affect the purchase price of a bond. P/E = price per earnings. low P/E (P/E < 4) means stock is undervalued. I'll try.  First forget everything OP said (your point? yay!).  Gold has value because it is stamped with a value on the front (say, 10 denarius).  This coin can then be used to pay taxes to Rome.  The value of the coin is the stamp value, not the value of the underlying gold.  The seignorage is the difference in price between the underlying metal and the marked value.    Because the coin has a very valuable use (paying taxes) that the metal doesn't have, the government gets to keep the difference between value and coin price.  Paper dollars are just like gold coins with a higher seignorage value.
