- Initial balance: The amount of starting capital used to invest in the asset or portfolio. In this case, we're starting with a $10,000 investment on October 1978.
- Final balance: The amount of capital we've accrued over time as of December 2024.
- Annual return: Also known as annualized return, or CAGR (Compound Annual Growth Rate), measures how much an investment has increased on average each year, during a specific time period. The time period in this case is approximately 46 year(s). Even a small difference in return can have a big impact on the final balance over a long period of time.
- Annual volatility: Basically indicates how much, in percentage points, the investment can deviate from its annual return, under most circumstances. An investment with an annual return of 5% and an annual volatility of 10% would indicate returns from approximately -5% to 15% most of the time. A lower volatility is usually preferred to ensure more steady returns over time.
- Best year: The best performance attained over its lifetime in a given year.
- Worst year: The worst performance undergone over its lifetime in a given year.
- Max drawdown: The largest percentage drop from a peak to a trough of an asset or portfolio, before a new peak is attained. Maximum drawdown is an indicator of downside risk over a specified time period.
- Sharpe Ratio: The Sharpe ratio measures the performance of an investment compared to a risk-free asset, after adjusting for its risk. A Sharpe Ratio above 1 is considered good.
- Sortino Ratio: The Sortino Ratio is a variation of the Sharpe ratio that only penalizes the investment for negative volatility/outcomes, and not for positive volatility. A Sortino Ratio above 1 is considered good.
- Adjusted Sortino Ratio: Sortino Ratio/√2. To allow for comparing the Sortino ratio to the Sharpe ratio, we multiply the risk measure of the Sortino ratio by the square root of 2 (which is the same as dividing the Sortino ratio by the square root of 2).
- Ulcer Index: The Ulcer Index (UI) is a technical indicator that measures downside risk in terms of both the depth and duration of price declines.
- Gain to Pain Ratio: The sum of all returns divided by the absolute value of the sum of all negative returns. In essence, the GPR shows the ratio of net returns to the losses incurred in getting those returns.

Drawdown Periods
Simply said, a drawdown is the "pain" period experienced by an investor between a peak (new highs) and subsequent valley (a low point before moving higher). In the table below are the fifth largest drawdowns encountered for the portfolio/asset in question.
Western Digital Corporation
| Start | Valley | End | Days | Drawdown |
|---|---|---|---|---|
| 1997-08-21 | 2001-09-27 | 2013-04-10 | 5711 | -96.2% |
| 1987-05-13 | 1991-12-12 | 1996-08-02 | 3369 | -93.75% |

| 2014-12-23 | 2016-05-13 | 2018-03-16 | 1179 | -67.69% |
The Western Digital Corporation took approximately 96 months on average to recover from a major drawdown. The longest drawdown lasted 190 months.
Underwater plot
The underwater plot shows you the drawdown periods on a chart. Whereas the performance chart usually gives you a positive viewpoint, the underwater plot gives you a pessimistic viewpoint. It helps you to visualize downtrends that occurred and how long it took for the portfolio's value to rebound to hit a new high after suffering a loss.
