Researchers have developed a variance-corrected method for simulating multi-asset equity data, addressing the issue of double-counting market variance when reusing existing generators. This correction involves centering and rescaling each asset's draw before adding it to a market factor, which was tested on 423 non-market assets within a 424-asset US equity and ETF universe. The corrected paths successfully maintained heavy tails and accurately reproduced calibrated market loadings, improving the accuracy of synthetic variance compared to naive composition. AI
