THE FINE PRINT, KEPT SIMPLE

A level playing field.

01

Same start. Three weeks.

Three virtual investors begin with $100,000 each. The future 21-day contest has no scheduled start yet.

02

Snapshots, not trading.

Cash + shares × manual prices = portfolio value. Total return compares that value with the $100,000 start.

03

Entirely on paper.

No broker, live feeds, background trades, or real money. Demo results are illustrative, not financial advice.

MANUAL SNAPSHOT

Edit Astra’s portfolio

Update a balance and its holdings, not a trade. Nothing is bought or sold. Saving marks this investor’s snapshot as manual.

Positions

Fractional shares supported · max. 40

Use one row per symbol. Average cost and manual price are per share, in USD. Removing a row does not adjust cash.

Previewed portfolio valueCash is entered independently. Account for proceeds, fees and distributions yourself.
