Values use the units disclosed in the source. Where a dollar scale cannot be established, the original amount is shown as filed. Rows may include separate allocations, options and principal amounts; these are kept separate from the covered-stock portfolio used for performance.

How copying its 13F would have done

CopyS&P 500 $10,000 copying Ostrum Asset Management's usable filed holdings in companies we cover from February 15, 2019, rebalancing at the first weekly close after each usable filing and holding until the next, against the S&P 500 (total return). Missing prices carry their last observed value. Marked weekly, log scale. Before costs and taxes; misses trading within each quarter and anything 13F does not show (shorts, cash, bonds, non-US holdings).

Biggest drop −45.2% (S&P 500 −31.8%); beta 0.94; alpha −2.4% a year (t = −0.68); last 12 months +11.7% against +12.1%.
