# Read your portfolio
**Goal:** make sense of what zfin shows you. This guide walks the five
commands you'll reach for most -- `portfolio`, `analysis`, `review`,
`exposure`, and `perf` -- and explains how to read each one.
Every example below runs against the bundled
[`pre-retirement-both`](../../examples/pre-retirement-both/) household,
so you can follow along verbatim:
```bash
ZFIN_HOME=examples/pre-retirement-both zfin portfolio
```
(Dollar figures depend on live prices, so yours will differ.)
## `portfolio`: positions and value
```bash
ZFIN_HOME=examples/pre-retirement-both zfin portfolio
```
```
Portfolio Summary (examples/pre-retirement-both/portfolio.srf)
========================================
Value: $1,383,137.81 Cost: $658,837.01 Gain/Loss: +$724,300.80 (109.9%)
Lots: 13 open, 0 closed Positions: 5 symbols
Historical: 1M: +3.2% 3M: +13.3% 1Y: +24.5% 3Y: +56.4% 5Y: +56.1% 10Y: +182.6%
Symbol Shares Avg Cost Price Market Value Gain/Loss Weight ...

...
```
How to read it:
- **The header line** is your liquid total, total cost, and aggregate
gain/loss.
- **Historical** is the portfolio's blended price return over trailing
windows -- a quick "how have my holdings done" gut check.
- **Each position** shows aggregated shares, average cost, current
price, market value, gain/loss, and weight. Indented `open` rows are
the individual lots, tagged **LT**/**ST** (long/short-term holding
period) and the account.
- **Cash** is summarized by account at the bottom.
Manual-priced rows render in warning color so you know the price may be
stale. Full output shape: [`zfin portfolio`](../reference/cli/portfolio.md).
### Covered calls
zfin values a written (short) call by **capping the covered shares at
the strike**, rather than pricing the option contract -- it never looks
up a live option quote. When the call is in-the-money (the stock trades
above the strike), the covered shares are valued at the strike, since
that's the price you'd be assigned at; an out-of-the-money call gets no
adjustment, and an expired or closed call stops capping.
This differs from your brokerage, which tracks the call as its own line
with its own mark-to-market gain/loss. Example: you hold 100 MSFT and
wrote a $500 call. If MSFT trades at $510, zfin values those shares at
**$50,000** (100 x the $500 strike), not $51,000 (100 x $510) -- the
$1,000 of upside above the strike now belongs to the call holder. A
brokerage would instead show $51,000 of stock plus a separate,
losing short-call position.
This is deliberate, and for a covered call used as an exit strategy
it's the more useful number: the cap is the value you'll actually
realize when the call assigns. Mark-to-market would understate it,
because an in-the-money call also carries time value you'd only pay to
*buy it back* -- which a let-it-assign writer never does. (At $510 the
call might mark around $14, so a brokerage nets $496/share even though
you'll realize the full $500 at assignment.) The flip side: zfin is
built for covered-call and buy-write investors, not active option
trading -- it deliberately doesn't track the live mark-to-market swings
of contracts you intend to trade rather than hold to assignment.
## `analysis`: allocation breakdowns
```bash
ZFIN_HOME=examples/pre-retirement-both zfin analysis
```
`analysis` answers "how is my money allocated?" along five axes:
**Asset Category**, **Sector**, **Geographic**, **By Account**, and
**By Tax Type**. Each bar is a share of your liquid total.
```
By Tax Type
Traditional (Pre-Tax) █████████████████▋ 58.9% $815,290.06
Taxable ██████▍ 21.6% $299,010.60
Roth (Post-Tax) █████ 16.9% $233,732.95
HSA (Triple Tax-Free) ▊ 2.5% $35,104.20
```
The Sector and Asset Category axes need [`metadata.srf`](classify-holdings.md);
the Tax Type axis needs [`accounts.srf`](set-up-accounts.md). Anything
missing classification lands under "Unclassified" / "Unknown."
### Umbrella exposure
A personal **umbrella insurance** policy covers liability -- lawsuits
and judgments -- above your auto/home limits, and you size it to the
assets you'd need to protect. The last block estimates that target: how
much of your liquid net worth is **exposed** to a civil judgment
because it sits outside judgment-protected retirement accounts:
```
Umbrella exposure
Total liquid: $1,383,137.81
Shielded (retirement accounts): $1,084,127.21
Exposed (taxable + non-shielded pre-tax): $299,010.60 (21.6%)
↑ approximate umbrella target
```
The default rule treats anything that isn't `taxable` as shielded.
Override per account with `shielded:bool:false` in
[`accounts.srf`](set-up-accounts.md#4-advanced-flags) -- IRA protection
varies by state and isn't modeled automatically.
## `review`: per-holding performance and risk
```bash
ZFIN_HOME=examples/pre-retirement-both zfin review
```
`review` is a dashboard: one row per holding with trailing returns,
volatility, Sharpe ratio, max drawdown, and a taxable-percentage
column, plus automated **findings** at the bottom.
```
Symbol Sector Wt% 1Y 3Y ... 3Y-SR 10Y-SR 5Y-MaxDD Tax%
VTI Diversified 66.9% +30.2% +23.3% ... 1.29 0.90 24.8% 10.9%
QQQ Technology 3.5% +43.1% +29.3% ... 1.41 1.16 32.6% 0.0%
Findings (2 active, 0 acked, 0 resolved)
⚠️ VTI at 66.9% of liquid (warn at 50.0%, flag at 70.0%)
❌️ Diversified sector at 85.7% (warn at 60.0%, flag at 75.0%)
```
The findings flag concentration, sector dominance, volatility
outliers, and tiny positions against configurable thresholds. The
status icons at the top summarize which checks fired. See
[`zfin review`](../reference/cli/review.md).
### Acknowledging findings
Findings are re-derived every run, so one you've already judged
acceptable would otherwise nag you forever. Acknowledge it to record
*why* and drop it from the active list. This is an interactive step --
in the [TUI](../reference/tui.md) Review tab, move the cursor to a
finding and press:
- **`a`** -- acknowledge it (you can type a short reason, saved as a note).
- **`U`** -- un-acknowledge (return it to the active list).
- **`v`** -- toggle whether already-acknowledged findings are shown.
(Those are the defaults; `?` shows your current bindings.)
Acknowledgments persist in
[`acknowledgments.srf`](../reference/config/acknowledgments-srf.md)
beside your portfolio, so they survive across runs and are versioned
with the rest of your data. The CLI honors them -- `zfin review
--show-acked` includes acked findings in the table -- but only the TUI
can add or remove them.
## `exposure`: look-through to a single symbol
```bash
ZFIN_HOME=examples/pre-retirement-both zfin exposure SPY
```
`exposure` answers "how much of *X* do I really own?" -- combining
direct holdings with look-through into the ETFs you hold (matched by
CUSIP against each ETF's latest reported holdings):
```
Exposure to SPY (examples/pre-retirement-both/portfolio.srf)
========================================
Total exposure 17.3% $238,956.80
Direct 17.3% $238,956.80
Look-through 0.0% $0.00
```
This is most interesting for an individual stock you also hold inside
broad-market ETFs (e.g. checking your true NVDA exposure across VTI,
SPY, and QQQ). See [`zfin exposure`](../reference/cli/exposure.md).
## `perf`: trailing returns for one symbol
```bash
ZFIN_HOME=examples/pre-retirement-both zfin perf VTI
```
`perf` shows Morningstar-style trailing returns (price-only **and**
total return), as-of the latest close and as-of the most recent
month-end, plus risk metrics. For what "total return," "annualized,"
and "month-end" mean, see
[Returns and performance](../explanation/returns-and-performance.md).
