Formal languages

Terminal yield

In formal language theory, the terminal yield (or fringe) of a tree is the sequence of leaves encountered in an ordered walk of the tree. Parse trees and/or derivation trees are encountered in the study of phrase structure grammars such as context-free grammars or linear grammars. The leaves of a derivation tree for a formal grammar G are the terminal symbols of that grammar, and the internal nodes the nonterminal or variable symbols. One can read off the corresponding terminal string by performing an ordered tree traversal and recording the terminal symbols in the order they are encountered. The resulting sequence of terminals is a string of the language L(G) generated by the grammar G. * v * t * e (Wikipedia).

Par yield

The yield (aka, yield to maturity, YTM) is the single rate that correctly prices the bond; it impounds the spot rate curve. For each coupon bond, there is a different implied yield. The PAR YIELD is the yield (YTM) for a bond that happens to price at par, and therefore is equal to this bon

Yield to Maturity Interpretations (FRM T3-10)

[my xls is here https://trtl.bz/2HifflO] Superficially, the yield to maturity (YTM, aka yield) simply inverts the usual time value of money (TVM) inputs by solving for the yield as a function of four inputs: face (future) value, coupon (payment), maturity (time), and current price (present

The Dividend Yield - Basic Overview

This video provides a basic introduction into the dividend yield. It explains what it's used for and how to calculate it. The dividend yield is equal to the annual dividend divided by the current stock price times 100%. The annual dividend is equal to the quarterly dividend times 4 or t

Fixed Income: Twists are steepening or flattening of the yield curve (FRM T4-23)

[my xls is here https://trtl.bz/2v5jXvc] The drawback of yield-based duration and convexity is that implicitly they must assume a parallel shift in the rate curve. While there can be many non-parallel shift, the two most common are twists and butterflies. A twist is when the curve steepens

Par yields are swap rates (FRM T3-13)

[my xls is here https://trtl.bz/2HPIDMX] The par yield is the coupon rate that prices a bond to par. It is also effectively the swap rate. Discuss this video here in our FRM forum: https://trtl.bz/2VMMOVa.
