INDIVIDUAL METHODOLOGY单项方法论How RBI-MCW is constructedRBI-MCW 的构建方式Expand +展开 +
01
Hypothesis假设
A transparent market-cap construction may outperform the thesis-weighted index by letting public-market scale determine position size.
02
Universe样本范围
Every listed robotics company passing the shared reconciliation, governance, valuation, and tradeability screen at the snapshot date.
03
Weighting权重方法
Float-agnostic market capitalization using price times current shares outstanding, with iterative capped redistribution.
04
Caps权重上限
8% per company.
05
Cash现金
Fully invested; residual weight is redistributed among uncapped names.
06
Rebalance再平衡
Quarterly using market capitalization on each rebalance date.
07
Benchmark基准
SPY for broad-market comparison; RBI-system-ce-I for the weighting-method test.
Backtest limitations回测局限
- No dividends, buybacks, or transaction costs -- price return only.
- Non-USD prices converted to USD daily via yfinance FX history, unhedged.
- Shares outstanding is a single current snapshot applied across the whole window.
- Fixed small universe -- no survivorship-bias reconstruction.
- Mechanical construction, not analyst-reviewed the way RBI-system-ce-T/-I are: no per-company sourcing, caveat, or exclusion-gate review beyond the shared reconciliation/governance/valuation/tradeability screen.
