Checking freshness

Portfolios

Baskets built on this board, each a paper book of fractional shares booked at a real session close and marked nightly on total return.

New basket

No baskets yet. Build one — a name, a kind, capital and the weights — and it is booked at the last session close by the next mark, within five minutes.

A basket is booked once, at the latest SPY session’s close, with each name sized to its target weight of capital; its NAV is replayed from that day on close_tr every night. Since-inception is NAV over capital; vs SPY is the relative form (1+r)/(1+rSPY) − 1 over the same span. Nothing here is rebalanced.
