The poster child for this chaos is $Roundhill Memory ETF(DRAM)$ , launched in April 2026 to capture the unquenchable AI demand for data storage. Its heavily concentrated Big 3 holdings - $Micron Technology(MU)$ $SK hynix(SKHY)$ & Samsung Electronics experienced a wipeout this week.
I bought at the peak & was up 30% but did not take profits. I have experienced basement in the abyss.
Which one hurts the most? No.5: Unrealised profits turning into unrealised losses.
When I bought at the peak, or get caught in a systemic sector crash, I can blame the market. But when I am sitting on big green gains & did not take profits, I can only blame myself.
The lesson learnt is: the stock market does not pay you for being right. It only pays when you hit sell.
