Remaining positions are held as changes are marginal and thesis remains intact. Gross leverage stays well within the 3.0x limit. Avoiding overtrading by holding all active positions with no clear deterioration signals."

Avoiding overtrading by holding all active positions with no clear deterioration signals."
