Three checks on your portfolio, each against a stated limit
ShieldWall measures the holdings you save: how much rides on a single stock, whether volatility has suddenly jumped, and how deep a fall the same holdings took over the last two years. Free with an account.
Measurements, not recommendations. ShieldWall places no orders and doesn't tell you what to buy or sell.
What it checks
Concentration
Flags any single stock above 10% of your invested holdings, counting what your funds hold.
Volatility regime
Flags when your portfolio's last 20 sessions are more than twice as volatile as the 60 before.
Drawdown
Flags a peak-to-trough fall deeper than 20% over the last two years, and reports one-day tail risk.
On a saved portfolio, ShieldWall counts what your funds hold.
How it works
- 1
Add your holdings
Build a portfolio from the screener, or import a CSV with tickers and quantities.
- 2
Run a scan
Each check is measured from delayed, split- and dividend-adjusted daily closes, and shows the number behind it.
- 3
Read the findings
A check that can't be measured says so instead of guessing. Recent changes show when a check moves between clear and flagged.
What it doesn't do
- On a free account it doesn't run on its own: scans run when you click Run scan. Nightly monitoring comes with Investor and Pro.
- It doesn't predict losses. Past behavior does not bound future losses.
- It doesn't place orders or give personalized investment advice.
- Holdings without US price history are listed as not measured.
