This is really interesting and worth explaining in simple terms. - AI "theme" stocks ( $Micron Technology(MU)$ $SanDisk Corp.(SNDK)$ $NEBIUS(NBIS)$ $Intel(INTC)$ etc) are so hot right now traders/hedge funds "have to" own them. - If you're a long/short/leveraged fund you need to go long Stock A/short Stock B. That's the "game." - What do you short if you're going long parabolic AI stocks? Something that isn't going to burn you. A stock that's solid but stodgy or could be disrupted would be perfect. - So you buy NBIS and go short $Uber(UBER)$ - Maybe you buy MU and short
