OBV
On Balance Volume (OBV) is a momentum indicator that relates volume to price change.

On Balance Volume is a running total of volume calculated by adding the day's volume to a cumulative total when the price closes up, and subtracting the day's volume when the security's price closes down.

It shows if volume is flowing into or out of a security.

When the security closes higher than the previous close, all of the day's volume is considered up volume. When the security closes lower than the previous close, all of the day's volume is considered down volume.

Odd Lot
This refers to a trade order for less than the generally accepted number of units or shares for a security. For bonds, it is an order for less than 100 bonds.

For example, a trade order for less than 100 shares of stock is for an odd lot.

Offering Period
A period of time, with a stated beginning and end date, during which payroll deductions are accumulated for the purchase of stock in an employee stock purchase plan. Each offering period may have its own rules for employee eligibility, stock purchase discount, and other terms. Refer to your plan rules for more information.

For new issue fixed income securities (e.g., bonds), this is the expected start and end date of the period during which you can place an indication of interest in a new issue offering.

Offer Price
The price at which mutual fund shares were sold.

For a no-load fund, this price is the same as the NAV.

For fixed-income securities (e.g. bonds), this is the price for the securities.

144(k)
Securities have this restriction if the securities are restricted, but the stock owner is not an affiliate of the company and the securities were acquired from the company or affiliate of the company more than two years ago.

You can sell this type of stock without having to satisfy most of the requirements of Rule 144.

1 Yr. %
The percent gain or loss that the portfolio has achieved over the previous one-year period. Refer to the "as of" date to determine the exact period.

On the Close
A time-in-force restriction that can be placed on the execution of an order. This restriction requires that the order is executed as close as possible to the closing price for a security. All or any part of the order that cannot be executed at the closing price is canceled.

On the Open
A time-in-force restriction that can be placed on an order. This restriction requires that the order is executed as close as possible to the opening price for a security. All or part of the order can be executed. Any part of the order that cannot be executed at the opening price is canceled.

One Cancels the Other (OCO)
A one cancels the other order is an order whose execution results in the immediate cancellation of an order linked to it. Cancellation of the linked order happens on a best efforts basis. In a one cancels the other order, both orders may be live in the marketplace at the same time. The execution of either order triggers an attempt to cancel the unexecuted order. Partial executions will also trigger an attempt to cancel the other order.

100-Day Moving Average
The average closing price of the stock ove rthe last 100 trading days. Moving averages can be used to guage the direction of price movement in a stock.

One Triggers the Other (OTO)
A one triggers the other orders involves two orders—a primary order and a secondary order. The primary order may be a live order at the marketplace. The secondary order, held in a separate order file, is not. If the primary order executes in full, the secondary order is released to the marketplace and becomes live. An OTO order can be made up of stock orders, option orders, or a combination of both.

Open Interest
The total number of outstanding option contracts for this security, that is the number of option contracts that have not been exercised, closed out, or allowed to expire.

Open Order
This is an order status indicating that an order that has been placed and no part of the order has been executed.

Open Price
The price of the security at the start of the current trading day.

Operating Margin, TTM (%)
This value measures the percent of revenues remaining after paying all operating expenses. It is calculated as the trailing 12 months (TTM) operating income divided by the trailing 12 months total revenue multiplied by 100.

Option
An option is a right to buy or sell shares at a guaranteed price for a specific period of time. With a call option, the buyer has the right to buy shares of the underlying security at a specific price for a specified time period. With a put option, the buyer has the right to sell shares of the underlying security at a specified price for a specified period of time.

Option Adjusted Convexity
Option Adjusted Convexity is the change in price of the bond not explained by option-adjusted duration. It is a measure of the curvature of the price-yield relationship of a bond after adjusting for any embedded options. The calculations are based on the Black-Karasinski model (an option valuation model in which the interest rate term structure is lognormal), for which the key assumptions are:

The calculations use the current offered price as the price input versus the previous day's closing yield curve. All calculations are provided by BondDesk, LLC.

Option Adjusted Duration
Option Adjusted Duration is the modified duration of a bond after adjusting for any embedded optionality. The Option Adjusted measure of duration takes into account the fact that yield changes may change the expected cash flows of the bond because of the presence of an embedded option, such as a call or put. The calculations are based on the Black-Karasinski model (an option valuation model in which the interest rate term structure is lognormal), for which the key assumptions are:

The calculations use the current offered price as the price input versus the previous day's closing yield curve. All calculations are provided by BondDesk, LLC.

Option Adjusted Spread
Option Adjusted Spread is a measure of a bond's extra return over the return of a comparable Treasury bond net of the cost of any embedded options. It is calculated as the spread over the Treasury spot curve that equates the present value of a bond's cash flows to its market price, incorporating the fact that the bond's cash flows may change under different interest rate environments. The calculations are based on the Black-Karasinski model (an option valuation model in which the interest rate term structure is lognormal), for which the key assumptions are:

The calculations use the current offered price as the price input versus the previous day's closing yield curve. All calculations are provided by BondDesk, LLC.

Option Adjusted Yield
Option Adjusted Yield is calculated by adding/(subtracting) the value of a call option/(put option) to the bond's market price to obtain the price of an otherwise equivalent but option-free bond. The yield that equates this new higher/(lower) price to the bond's cash flows to maturity is the Option Adjusted Yield.

OID reports the earned portion of the difference between the stated redemption price at maturity (if greater than one year) and the issue price of a bond, debenture, note, or other evidence of indebtedness issued at a discount (e.g., zero-coupon bond, long-term CD) that is attributable to the selected tax year.

When viewing bond details, the OID field displays L (long term) if the security is subject to OID and the period of time between the maturity date and the dated date is greater than 10,000 days. If the period of time is equal to or less than 10,000 days, S (short term) displays.

Important:   Tax reporting of OID obligations is complex; if you paid acquisition or bond premium, or if the obligation is a stripped bond or stripped coupon, you must compute the proper amount of OID. If you must compute your proper OID, refer to IRS Publication 1212, List of Original Issue Discount Instruments, to figure the correct OID.
