) are also neutralized. The targets are in effect Numerai's custom "specific return" or "residual return".target_20d
). This score is simply referred to as corr
throughout this doc and the website.corr
is a measure of how well your signal correlates to a target that is neutralized to all signals known to Numerai, Meta Model Contribution (MMC) is a measure of how well your signal correlates to a target that is neutralized to all signals known to Numerai and all other staked signals on Numerai Signals. This score is simply referred to as mmc
throughout this doc and the website.mmc
of a signal is computed by first constructing a special signal called the Signals' Meta Model, which is defined as the stake weighted average of all the (ranked and neutralized) signals on Numerai Signals for a given round. The mmc
of a signal is the correlation of the signal to the target after being neutralized to the Signals' Meta Model.corr

) you want to stake on.stake_value
is the value of your stake on the first Friday (scoring day) of the round.stake_cap_threshold
is a number that determines when the payout_factor
begins to decay. At the time of this writing, the Signals stake_cap_threshold
is 150K. The stake_cap_threshold
can change per round at Numerai's discretion.payout_factor
is a number that scales with the total NMR staked across all models in the tournament. When the total NMR staked across all models exceeds the stake_cap_threshold
, the payout_factor
is reduced.corr_multiplier
and mmc_multiplier
are configured by you to control your exposure to each score. You are given the following multiplier options.data_date
- dates corresponding to the underlying stock market data. All data_dates
refer to the market close of that date and do not include a time. For example, values in the friday_date
column of submissions are of type data_date
.effective_date
- dates corresponding to actions or events that take place on Numerai Signals and may include a time which is always specified in UTC. There is usually a delay between the data_date
and the effective_date
because of time zones and the time it takes for stock market data to be processed. Unless otherwise specified, all dates mentioned in the website and this doc are of type effective_date

. The deadline for submissions and staking is at Monday at 14:30 UTC
. Late submissions will not be scored and will not count for payouts. Stake changes made after the deadline will apply to the next round.round
is defined by the data_date
of the prior Friday. The 20 days of scoring and payouts are based on 3day-2day
through 22day-2day
neutralized returns. There is a 2 day lag between market close for a day and when the data becomes available for scoring. For example, the 22day-2day
neutralized returns are up to Tuesday market close, but only become available on Thursday.corr
