Cash Account

Efficient Market Hypothesis (EMH)
The theory stating that financial markets process all available information directly into prices, making it impossible to consistently beat the market on a risk-adjusted basis.
Weak form EMH
A form of EMH where all historical price data is incorporated into the price; technical analysis is useless here.
Semi-strong form EMH
A form of EMH where all publicly available information is incorporated into the price; fundamental analysis yields no extra return here.
Strong form EMH
A form of EMH where all information (including insider knowledge) is incorporated into the price; insider trading is not profitable here.
Joint Hypothesis Problem
The methodological problem stating that outperformance (α) can never be tested independently of a risk model (like CAPM); a positive alpha could mean an inefficient market or an incorrect risk model.
Prospect Theory
Behavioral theory by Kahneman & Tversky (1979) stating that people evaluate outcomes relative to a reference point rather than absolute wealth.
Loss aversion
The psychological fact that the pain of a loss is experienced as approximately twice as intense as the pleasure of an equal gain.

Risk averse in gain
The phenomenon where people in a gain scenario prefer a certain, smaller amount over an uncertain larger amount.
Probability weighting
The cognitive bias where people systematically overestimate small probabilities (making lotteries and startups attractive).
Frame dependence
The bias where a decision depends heavily on how the choice is presented (framed).
Herding
The irrational imitation of the behavior of the large mass of investors.
Disposition effect
The emotional error where investors hold onto losing stocks too long and sell winning stocks too quickly.
Familiarity bias
The misconception that personal knowledge of a company or country equates to better information, leading to under-diversification.
Regret aversion
The fear of repeating previous psychological pain, which causes long-term goals to be missed.
Limits to Arbitrage
The concept (Shleifer & Vishny, 1997) that rational investors cannot always correct mispricings due to frictions, costs, or risks.
Noise Trader Risk
The risk that irrational investors (noise traders) push a price further in the wrong direction, potentially causing an arbitrageur to go bankrupt before the price corrects.
Value trap
A stock that appears cheap based on a low P/E ratio, but is actually a poor investment due to fundamental problems or high risk.
Support level
A historical price low where many buyers enter, causing the price to stop falling and rise again.
Resistance level
A historical price high where many investors take profits, causing the price to stop rising and fall again.
Breakout
The moment a market price breaks through a support or resistance level with conviction.
Bullish signal
A buy signal in technical analysis, e.g., when a short-term Moving Average crosses a long-term Moving Average from below to above.
Bearish signal
A sell signal in technical analysis, e.g., when a short-term Moving Average crosses a long-term Moving Average from above to below.
Misperceiving randomness
The human tendency to see patterns in completely random price sequences (hot-hand / gambler's fallacy).

Endlessly backtesting historical data until a pattern is coincidentally found that has no predictive value for the future.
Event Study Methodology
A statistical method to test if abnormal returns (AR) occur around a specific event (such as an earnings announcement).
Strategic Asset Allocation (SAA)

Tactical Asset Allocation (TAA)
Deliberately deviating from the SAA in the short term to generate extra return through market timing.
Loser's Game (Stock-picking)
The concept that active stock selection is statistically doomed to lose, as only ~1.3% of global stocks are responsible for all outperformance above the risk-free rate.
Time in the market
The principle that staying permanently invested is more important than market timing, because missing the few best market days dramatically destroys terminal wealth.
Factor Investing
A systematic investment style that filters broad index funds based on specific, structural risk premiums (such as Value or Momentum).
Size premium
The empirical phenomenon that small-cap stocks on average achieve better long-term returns than large-cap stocks.
Granular Economy (Paper)
An economy/market highly concentrated around a small number of mega-companies; high concentration predicts a higher future size premium due to capital misallocation.
Momentum (11/1/1)
A strategy of buying stocks based on performance over the past 11 months, deliberately skipping 1 month (t−1) to avoid micro-reversals, and holding the position for 1 month.
Momentum Crash
An extreme trend reversal where the short side of a momentum portfolio (historical losers) suddenly sky-rockets after a major market crisis, leading to massive losses for the strategy.
Value-factor
Systematically overweighting stocks that are cheap relative to their book value (high Book-to-Market ratio).
Low Volatility Anomaly
The empirical discovery (contrary to CAPM) that low-risk/low-beta stocks provide risk-adjusted returns as good as or better than high-risk stocks.
Leverage Constraints
Institutional restrictions forbidding many professional funds from borrowing money; this forces them to buy high-beta stocks instead, leaving low-risk stocks structurally undervalued.
Agency Issues (Robeco)
The separation between management and asset owner; fund managers focus too rigidly on their benchmark and avoid low-volatility stocks for fear of excessive tracking error.
Quality Minus Junk (QMJ)
A fundamental factor strategy (Asness et al., 2018) that goes long profitable, growing, and safe companies, and short low-quality companies; success is explained academically by mispricing.
Drawdown
The maximum loss measured from the highest peak to the lowest trough (peak-to-trough) in a specific period.
Limited Partnership
The legal structure of most PE and hedge funds, consisting of a general partner (GP) and silent investors (LPs).
General Partner (GP)
The manager of a Private Equity or Hedge fund who makes operational decisions and closes deals.
Limited Partners (LP)
External institutional investors (such as pension funds) who purely provide the capital in an alternative structure.
High-water mark
A protection mechanism stating that a hedge fund manager may only collect a performance fee if the fund value exceeds its highest historical peak.
Hurdle rate
The minimum return (e.g., 5−8%) a fund must achieve before the manager is eligible for a performance fee.
Clawback
A contractual clause requiring the GP to return previously paid performance fees to LPs if the fund suffers heavy losses in later years.
Venture Capital
A Private Equity style focused on startups and young companies with high growth potential, characterized by very high risk and negative operating cash flows.
Leveraged Buyout (LBO)
A Private Equity style where a mature company with stable cash flows is acquired using a very large amount of debt (leverage).
Distressed
Investing in the debt or equity of companies experiencing significant financial or operational difficulties.
Secondaries
The secondary market within Private Equity where investors buy existing LP interests from each other for interim liquidity.
Co-investment
A structure where an LP invests directly in a specific deal alongside the PE fund, avoiding standard 2/20 fund fees on that portion.
J-Curve
The graphical representation of cumulative returns of a PE fund; negative in the early years due to capital calls and fees, then curving steeply upward in later years through exits.
Vintage Risk
Timing sensitivity in Private Equity; market conditions and the economic cycle in the fund's starting year largely determine final success.
Distribution Waterfall
The contractual order of profit distribution in a PE fund (Return of Capital → Hurdle → GP Catch-up → 80/20 Split).
Carried interest
The final performance bonus (usually the 20% from the profit split) received by the GP after successfully passing through the distribution waterfall.
REIT (Real Estate Investment Trust)
A publicly traded real estate fund providing investors liquid access to a diversified portfolio of direct real estate.
Core real estate
The safest real estate strategy focused on stable, well-leased buildings in top locations with low leverage (LTV 20−30%).
Opportunistic real estate
The most risky real estate strategy focused on speculative project development with very high leverage (LTV >75%).
