Personal Investment Record

As of 2025.11.30

———————

In October, I bought some $MSTR 2X Long ETF(MSTU.US) and lost big time. Later, I cut my losses at over 60%. I won’t touch these things anymore—just stick to steady index investing. I don’t want to mess with anything else (✋･_･). If it weren’t for MSTU, my monthly return could’ve been positive… Currently, my YTD return is 30.56%. Due to limited capital, selling PUTs isn’t very flexible. I’ll try more options when I have more funds. So this month, I came up with a new strategy: when QQQ drops 5%, 10%...40% from its peak, I’ll sell portions of $Invesco QQQ Trust(QQQ.US) and $iShares US Tech(IYW.US), then add to $Proshares UltraPro QQQ(TQQQ.US) and $Direxion Tech Bull 3X(TECL.US). I’ll clear leveraged ETFs when QQQ’s PE hits 35+. One more thing: when I buy leveraged ETFs, I’ll re-enter only after QQQ drops 5% from a new high, provided the initial buy was at a 10% drop from the previous high. This ensures I only buy leveraged ETFs once near each of the 5%, 10%...40% drop points. Otherwise, it’d be chaotic. Of course, this strategy still feels imperfect and needs more thought.

This involves a reference point—why QQQ’s drop? Because leveraged ETFs have decay (though I don’t care much), and their underlying is these index ETFs. Using QQQ as a reference helps time leveraged ETF trades better.

Lastly, hope December ends well. Wishing everyone big gains!
