Bayes' Theorem
P(A∣B)=P(B∣A)⋅P(A)P(B)P(A|B) = \frac{P(B|A) \cdot P(A)}{P(B)}

Fisher relation (real vs nominal return)
(1+Rnominal)=(1+Rreal)(1+i)(1 + R_{nominal}) = (1 + R_{real})(1 + i); R_nominal = nominal, R_real = real, i = inflation. Subtracting inflation is only an approximation; it breaks down when inflation is high.
Time-weighted return (TWR)
(1+TWR)=∏i=1n(1+ri)(1 + TWR) = \prod_{i=1}^{n}(1 + r_i) — r_i = holding-period return for sub-period i, n = number of sub-periods between external cash flows

Fisher effect
(1+rnom)=(1+rreal)(1+π)(1 + r_{nom}) = (1 + r_{real})(1 + \pi)
Approx: rnom≈rreal+πr_{nom} \approx r_{real} + \pi
r_nom = nominal rate, r_real = real rate, π\pi = expected inflation
Breakeven and shutdown points
Breakeven: P=ATCP = ATC (price covers all costs).
Shutdown (short run): P<AVCP < AVC. If AVC<P<ATCAVC < P < ATC, keep operating short-run because contribution covers some fixed cost.
Price elasticity of demand
Ed=%ΔQd%ΔPE_d = \frac{\%\Delta Q_d}{\%\Delta P}
∣Ed∣>1|E_d| > 1: elastic (revenue rises when P falls). ∣Ed∣<1|E_d| < 1: inelastic. =1= 1: unit-elastic (revenue maximized).
Cross-rate calculation
AC=AB×BC\frac{A}{C} = \frac{A}{B} \times \frac{B}{C}

r = risk-free rate, T = time to expiration
Forward contract price
F0=S0(1+r)TF_0 = S_0(1+r)^T
With continuous dividends: F0=S0e(r−q)TF_0 = S_0 e^{(r-q)T}
S_0 = spot, r = risk-free rate, T = time, q = dividend yield
Forward price with discrete income or cost
F0(T)=(S0−PV(I)+PV(C))(1+r)TF_0(T) = (S_0 - PV(I) + PV(C))(1 + r)^T
I = discrete income (dividends, coupons) over T; C = carrying cost (storage). PV at risk-free rate. Income reduces the forward; cost raises it.

Long call: max⁡(ST−X,0)\max(S_T - X, 0); Long put: max⁡(X−ST,0)\max(X - S_T, 0)
STS_T = price at expiry, X = strike. Short positions are the negative of long. Subtract premium paid for profit.
Intrinsic value and time value
Call intrinsic: max⁡(S−X,0)\max(S - X, 0); Put intrinsic: max⁡(X−S,0)\max(X - S, 0)
Time value = Option price − intrinsic. ATM/OTM intrinsic = 0; deep ITM time value → 0 near expiry.
Lower bound on European options (no dividends)
Call: c≥max⁡(S0−X(1+r)−T,0)c \geq \max(S_0 - X(1+r)^{-T}, 0)
Put: p≥max⁡(X(1+r)−T−S0,0)p \geq \max(X(1+r)^{-T} - S_0, 0)

Debt Service Coverage Ratio (DSCR)
DSCR=NOIDebt serviceDSCR = \frac{NOI}{\text{Debt service}}
Debt service = annual principal + interest. DSCR > 1 means cash flow covers debt; CRE lenders typically require ≥ 1.20–1.30.
