$Direxion FTSE China Bull 3X(YINN.US) rose nearly 8 points today; the Hang Seng Index's single-day 2.4% gain is the standard output after leverage amplification; $CSOP KOSPI(03121.HK) rose almost 3 points, with Seoul's market action cashing out first during the Hong Kong session, while the US session's $Direxion Daily Korea Bull 3x Shares ETF(KORU.US) remained flat, as the time difference ground away the explosive power of leverage.

$A CSOP HSCEICC(02802.HK) basically didn't move—the covered call structure inherently trades upside potential for premium income, so it's destined to underperform on days of sharp rallies.

Leverage amplifies intraday returns, not trend returns; overnight holding costs will eat up most of the gains in a volatile market. In this round of recovery for Chinese assets, index leverage tools are suitable for pulses, not for lying flat; don't treat 3x leverage as a dollar-cost averaging strategy.
