Analyzing the Weekly Flows

The Thematic channel gathered $2,255M in net inflows over the trailing five days. Multi-Sector led all categories with $892M in inflows, followed closely by Disruptive Tech at $721M and Infrastructure at $336M, all three also showing substantial YTD accumulation. Natural Resources was the week’s largest outflow category at -$128M, despite carrying a strong $10,249M YTD inflow figure, while Alternative Equity and FinTech saw modest weekly outflows of -$16M and -$6M respectively. The contrast between short-term profit-taking in Natural Resources and sustained longer-term inflows suggests some tactical rotation rather than a broader reversal in thematic sentiment.
