$SUPER MICRO COMPUTER INC(SMCI)$ Jane Street increased their position by 52.2 million shares, an 1100% jump, between March 31 and June 11. This now makes it their single largest stock holding, right after their $SPDR S&P 500 ETF Trust(SPY)$ ETF position. Someone must know something. And look at all the runners among their core holdings—wowsa. Smart bears should be worried.
$Micron Technology(MU)$ I get it more than you might think. This is early NVDA, SHOP, MU. It will grow bigger than Barret can handle. The reign that was GOOG, META has to be distributed. The gates have opened. Short sellers are buying back in droves, check the next filing.
$SanDisk Corp.(SNDK)$ $Micron Technology(MU)$ $Roundhill Memory ETF(DRAM)$ Not overcomplicating this. SNDK from $214 to $2100. MU from $62 to $1074. Since that “Bargain of the Century” callout… all the information is still there publicly if you look back. What stands out to me now isn't the PnL, it's how long this theme has persisted. DRAM isn't trading like a one-off cycle anymore. It's starting to behave like a structural repricing of memory as a core input to AI infrastructure. Why does that matter? Because when a sector stops reacting like a normal cycle, you don't get clean tops… you get expansion phases that surprise people on the upside. The
A common misconception is that mega caps don't deliver multi-baggers. The key is to be early on the thesis before the consensus catches up. $Micron Technology(MU)$ ~$118 → $1,000+ (~9x) $Intel(INTC)$ ~$25 → $130+ (~5x) $SanDisk Corp.(SNDK)$ ~$500 → ~$2,000+ (~4x) $Advanced Micro Devices(AMD)$ ~$200 → $500+ (~2.5x) Whether it's small-cap asymmetric swings or large-cap long-term holds, I'll keep sharing notable finds and theses right here.
$SPDR S&P 500 ETF Trust(SPY)$ If they really wanted to, it seems like they could easily take out all the June monthly puts by Thursday. I wouldn't be too shocked by a move to 770 or a 4% weekly gain. Testing 760 feels like a given, unless there's a major disruption to the deal. But that would be a significant setback, which would likely cause some displeasure.
$Micron Technology(MU)$ The first major breakout happened after clearing the heavy positioning shelf around ~$130 – that was the initial "air pocket" move. Now we're seeing a second-leg attempt after consolidation, as price works through the next major supply zone. The key takeaway here: Shelf 1 cleared → impulsive expansion phase. Consolidation → digestion of prior positioning. Shelf 2 test → whether trend continuation stays intact or stalls. This is classic structure-driven price action in memory names – moves tend to come in stages, not straight lines, as positioning gets repriced in layers.
