# Investing Basics

## When to use this skill
Use when the user says things like:
- "How do I start investing?"
- "Explain investing basics for beginners"
- "What is dollar-cost averaging?"
- "Tell me about index funds"
- "What’s the best way to invest with little money?"


## Core Philosophy
Investing is the practice of putting money to work so it grows over time
through the power of compound returns. The core principle is that time in
the market consistently outperforms timing the market. A disciplined,
diversified, long-term approach is the most reliable path to wealth
accumulation for the vast majority of investors.

## Key Techniques
- **Index Fund Investing**: Purchase broad market index funds that track
  entire markets at minimal cost. This approach consistently outperforms
  most actively managed funds over long periods.
- **Dollar-Cost Averaging**: Invest a fixed amount at regular intervals
  regardless of market conditions. This reduces the impact of volatility
  and removes emotion from investment decisions.
- **Asset Allocation**: Divide investments among different asset classes
  (stocks, bonds, real estate, cash) based on risk tolerance, time horizon,
  and financial goals.
- **Rebalancing**: Periodically adjust portfolio holdings back to target
  allocations. This enforces a buy-low, sell-high discipline automatically.
- **Tax-Loss Harvesting**: Sell losing positions to offset capital gains,
  reducing tax liability while maintaining desired market exposure by
  purchasing similar but not identical replacement securities.

## Best Practices
- Start investing as early as possible. The difference between starting at
  25 versus 35 can be hundreds of thousands of dollars by retirement.
- Keep investment costs low. Expense ratios, trading fees, and advisory fees
  compound against you just as returns compound for you.
- Maintain an emergency fund of three to six months expenses before investing
  in volatile assets. This prevents forced selling during downturns.
- Understand the difference between tax-advantaged accounts (401k, IRA, Roth)
  and taxable brokerage accounts. Maximize tax-advantaged space first.
- Diversify across geographies, sectors, and asset classes. No single
  investment should represent a life-changing risk.
- Ignore daily market noise. Check portfolio performance quarterly at most.
- Reinvest dividends to maximize compound growth during accumulation phase.

## Common Patterns
- **Three-Fund Portfolio**: A total US stock market fund, a total international
  stock market fund, and a total bond market fund. Simple and effective.
- **Target-Date Funds**: A single fund that automatically adjusts asset
  allocation based on expected retirement date. Ideal for hands-off investors.
- **Core-Satellite Strategy**: Build a core of low-cost index funds and add
  small satellite positions in areas of conviction or interest.
- **Bucket Strategy**: Divide portfolio into time-based buckets. Short-term
  bucket in cash and bonds, medium-term in balanced funds, long-term in
  growth-oriented equities.

## Anti-Patterns
- Trying to time the market by moving in and out based on predictions or
  headlines. Missing even a few of the best days destroys long-term returns.
- Chasing past performance by buying whatever asset class or fund performed
  best recently. Past returns do not predict future results.
- Holding too much cash out of fear. Inflation erodes purchasing power
  steadily, making cash the guaranteed losing investment over long periods.
- Over-concentrating in employer stock or a single sector. Diversification
  is the only free lunch in investing.
- Panic selling during market downturns. Declines are normal and temporary;
  selling locks in losses permanently.
- Paying high fees for active management that statistically underperforms
  passive index approaches over meaningful time horizons.
