Learn the Stock Market in 80 Flashcards: From Open Outcry to Dark Pools

Deck YV8100 — Stock Market & Trading (80 cards) is a clean glossary: real definitions, no padding, no duplicates. But it is two decks stitched together. Cards 1-28 are the institution — how exchanges work, where they came from, how they break. Cards 29-80 are the practitioner's vocabulary. Study the second block first: it makes the first one readable.

What the 80 cards cover

Plumbing and history: stock exchange vs stock market, NYSE, NASDAQ, open outcry, bid-ask spread, market makers, liquidity, OTC trading, the Van der Beurze inn of 13th-century Bruges, the Dutch VOC, circuit breakers, S&P 500, Dow Jones, FTSE 100, the efficient market hypothesis, herding behaviour, pattern-recognition bias, bubbles, the dot-com crash.

How people actually trade: fundamental vs technical analysis, short selling and covering, margin buying, margin calls, naked shorting, ETFs, options, futures, derivatives, primary vs secondary markets, IPOs, dividends, stock splits, bull and bear markets, volatility, diversification, P/E ratio, blue-chip and penny stocks, price discovery, limit, market and stop-loss orders, insider trading, the SEC, mutual, index and hedge funds, value vs growth investing, day and swing trading, dollar-cost averaging, forex, bonds, yield, capital gains, systemic risk, dark pools.

Eight cards that show the level

Four cards to repair first

• Cards 47 and 48 are asymmetric. A bear market gets a hard threshold (down 20% from recent highs); a bull market only gets "prices are rising or expected to rise". Give card 47 the mirror rule: up 20% from a recent low.
• Maintenance margin is missing. Card 34 gives the 50% initial requirement (Reg T), card 35 defines the margin call — but the level that triggers it (25% FINRA minimum, often 30-40% at brokers) never gets a card.
• Card 19 credits the wrong body. The 7/13/20% halts are market-wide circuit breakers keyed to the S&P 500, not an NYSE rule; the 20% level closes the market for the day.
• Card 36 overstates. Naked shorting is restricted in the US by Regulation SHO (2005, tightened 2008) rather than flatly illegal everywhere.

Two fronts are also corrupted by the editor: card 14 ("Origin of the word 'bourse", unclosed quote) and card 32 ("Covering' a short position").

Two tips for this deck

Define the words the backs lean on. Intrinsic value carries cards 27 and 66, earnings per share hides inside the P/E back, and bid and ask are used in card 6 before card 7 explains them. Four new fronts fix the chain.

Nothing here computes anything. Add five numeric cards and the glossary becomes usable: a P/E from a price and an EPS, the price at which a 50%-margin position gets called, a 3-for-1 split on a $150 share, a 20% drawdown, a dividend yield.

Hints are empty on all 80 cards — a good place to park the regulator or the year behind each term.
