$QSI You know this may be one of the most attractive buying opps out there in that the SP has not participated in the gargantuan Q rally. Looks promising, stepped in with a small chunk & will let it run once it can separate from the 2’s. MM could spin this positively with nice long GREEN candles!!

$QSI The stock has a larger than normal after hours volume. Looks like a good pre market tomorrow. May move down in the pre market then bounce up into the liquidity being created by BIGS moving into the stock. Dailey volume has doubled and picking up!

$QSI When to sell, you ask? When a friend — who’s never mentioned a stock in his life — suddenly tells me, “Hey, check out this hot new one called QSI.” That’s my sell signal. Until then, diamond hands!

The fact that he said this is a Quantum firm means it IS A QUANTUM FIRM. This is going to freaking fly. $RGTI $QUBT $QBTS $IONQ
