He describes this as a simplified version of the strategy employed by Warren Buffett and Charlie Munger of Berkshire Hathaway. He touts the success of his magic formula in his book 'The Little Book that Beats the Market' (ISBN 0-471-73306-7 published 2005, revised 2010), stating it averaged a 17-year annual return of 30.8%.

However the 10-year vs 3-month portion did not invert until March 22, 2019 and it reverted to a positive slope by April 1, 2019 (i.e. only 8 days later). [26] [27] The month average of the 10-year vs 3-month (bond equivalent yield) difference reached zero basis points in May 2019. Both March and April 2019 had month-average spreads greater than ...
For an MBS, the word "option" in option-adjusted spread relates primarily to the right of property owners, whose mortgages back the security, to prepay the mortgage amount. Since mortgage borrowers will tend to exercise this right when it is favourable for them and unfavourable for the bond-holder, buying an MBS implicitly involves selling an ...
The bear put spread improves the breakeven price, which would be $19 with a long put alone, but is now only $19.50 with the spread strategy, or the long put’s strike price minus the net premium.
A long butterfly options strategy consists of the following options: Long 1 call with a strike price of (X − a) Short 2 calls with a strike price of X; Long 1 call with a strike price of (X + a) where X = the spot price (i.e. current market price of underlying) and a > 0. Using put–call parity a long butterfly can also be created as follows:
The binomial model was first proposed by William Sharpe in the 1978 edition of Investments (ISBN 013504605X), [2] and formalized by Cox, Ross and Rubinstein in 1979 [3] and by Rendleman and Bartter in that same year. [4] For binomial trees as applied to fixed income and interest rate derivatives see Lattice model (finance) § Interest rate ...
Yield spread can also be an indicator of profitability for a lender providing a loan to an individual borrower. For consumer loans, particularly home mortgages, an important yield spread is the difference between the interest rate actually paid by the borrower on a particular loan and the (lower) interest rate that the borrower's credit would allow that borrower to pay.
Suppose S 1 (t) and S 2 (t) are the prices of two risky assets at time t, and that each has a constant continuous dividend yield q i. The option, C, that we wish to price gives the buyer the right, but not the obligation, to exchange the second asset for the first at the time of maturity T. In other words, its payoff, C(T), is max(0, S 1 (T ...
