Investing for Programmers
Leverage is the use of debt financing to increase the scale of a company’s assets or investments relative to its equity.
- How it is used
- Assesses how debt supports assets, growth, or trading exposure while highlighting the resulting ability to absorb losses.
- How deep it goes
- Defines D/E and interest coverage, compares companies, and illustrates trading losses, but stops short of detailed valuation or modeling.
- Examples
- Uses Apple, Walmart, NVIDIA, and a hypothetical $500,000 leveraged purchase to contrast strategic debt with trading losses.
- What you can do after
- Evaluate leverage by combining debt, interest coverage, liquidity, profitability, costs, and downside-risk evidence.

Leverage is the use of borrowed funds to increase the size of an investment position relative to the investor's own capital.
- How it is used
- Uses borrowing or weight scaling to raise portfolio exposure and expected return, especially when unlevered risk-parity returns are comparatively low.
- How deep it goes
- Explains scaling, margin mechanics, financing costs, and liquidation risks, but defers institutional derivatives-based leverage.
- Examples
- Uses scaled risk-parity weights, a 60/40 comparison, and a $1 million portfolio borrowing $500,000 for a $1.5 million tangent-portfolio position.
- What you can do after
- Apply it via margin borrowing or a risk-free asset to scale exposure while accounting for interest costs and margin calls.
