Trading Review Pt.5 (26/06/18)

Busy, busy, busy.

I’ve genuinely traded a lot less this stretch, largely because school has been insanely busy — no time to trade, let alone time to write reviews.

I ran my positions pretty full last time in May, close to 80%. Position management, on a long horizon, might be an entropy-increasing process — sometimes you’re just idle and want to buy a little something, without thinking it through enough. That might be a problem.

I shall strike in full-position formation.

Micron and Memory

The original plan was just to beat the Nasdaq for the year — by past-average backtests that might even let me feed myself independently. Instead, the opening move landed me a doubler. Part of it, credit to the tape: the Nasdaq just printed a one-month rally not seen in who knows how many years, actually allowing a company worth hundreds of billions of USD to double within a single month — genuinely never seen before; part of it is a repricing process in HBM and memory. Honestly, the repricing itself isn’t jaw-dropping; the only dizzying thing is how fast all of it happened.

Hooked on MU, this lifetime might be ruined.

My life, at least since high school, has been one long while(true) review. Reviewing might be seen as a data augmentation + self-supervised learning process; the side effect is it can make me more obsessive, but past experience has overall done more good than harm. The vast majority of my reviews are completely unfit for human eyes, but the stock-market ones can be displayed publicly, so let me write one up.

Just a leek's fantasy before the harvest.

Over the past month I’ve collected several rounds of angel funding one after another, and the stuff in my hands is gradually getting unlocked — finally at a scale where trading actually means something. Maybe, if I play my cards right, feeding myself independently isn’t impossible. Of course, the prerequisites for that hypothesis are still a bit hard to meet.
