Investing Foundations
  • Investing is long-term ownership of assets for income or appreciation
  • Speculation is short-term betting on price movement
  • Short-term markets are unpredictable
  • Price movements are often emotional not intrinsic
  • Past performance doesn’t predict future results
  • Experts can’t consistently beat randomness
  • Bubbles are driven by greed and hype over fundamentals
  • Bubbles can last a long time but eventually correct
  • Most people fail to exit before crashes
  • Big innovation does not guarantee early profits
  • Focus on whether an industry can sustain profits
  • Long-term success favors diversified buy and hold strategies
  • The hardest part is resisting speculation
    Early History
    • Tulip Mania: rare bulbs became speculative status symbols, worth as much as houses, then collapsed to near zero
    • South Sea Bubble: hype-driven company with royal backing inflated stock, then collapsed, triggering financial crisis
    • Great Depression crash: margin buying and speculation drove extreme boom, then a ~50 percent market collapse in weeks
      1960s – 1990s
      • 1950s-60s tech boom: anything electronic surged on hype, then fell in 1962
      • Conglomerates: acquisitions inflated earnings, expectations collapsed, stocks fell 40%
      • Story stock era: narrative-driven hype led to extreme valuations
      • Nifty Fifty: “safe” blue chips priced for perfection, then suffered major valuation declines
      • Biotech/microelectronics: IPO and small-cap speculation ended in ~90% declines
      • Japan: massive real estate and stock mania, Tokyo property worth more than all the U.S., stock value was 2x the world’s, then a decades-long crash after 1989 peak
        2000s
        • Dot-com: internet hype, new metrics replaced profits, NASDAQ tripled then collapsed
        • Valuations detached from fundamentals with extreme P/E ratios and IPO spikes
        • Massive wealth destruction across major tech stocks and indices
        • Housing bubble: mortgages bundled into securities, risk obscured by the system
        • Rising demand drove home prices up, then collapse caused widespread negative equity
        • Defaults and foreclosures surged, freezing credit markets and triggering recession
