QSI Quantum-Si Incorporated - Ordinary Shares - Class A

$QSI Imagine someone deliberately shorting a life sciences company developing groundbreaking technology that could one day help diagnose and treat a wide range of diseases—from cancer to Alzheimer’s—and actually rooting for the company to fail, all to make a few dollars. How low can people go? To the shorts: What if one day you—or someone you love—needs one of these treatments? What if the technology you’re hoping will fail could someday make a difference in your own family’s life? And what if karma is real? There’s nothing wrong with investing based on your convictions. But celebrating the failure of companies working to advance human health is a different matter. Shame on you!

$QSI Strong close. What a week this was! I really think we will have a major news coming soon. no wonder shorts are worried...we have a couple of those here on our board. They are in trouble.

$QSI third rally day in a row. As i said, this is a monster and could make rich us all. Remember, this is just the beginning

$QSI honestly im seriously impressed. We only got the detection of 18 - 3 weeks ago and now we have 19! The 20 amino acids are coming soon for sure. Mgmt have repeatedly been confident on saying the goal will be by end of 2026! Only a matter of time

$QSI Fair question. QSI is not targeting small academic labs with Proteus. That’s what Platinum Pro is for and it’s not going away. $400K vs. $80K. In fact, I would not be surprised to see QSI lower the price of PP to expand the TAM. Proteus is targeting commercial wet labs, large academic research labs (think Harvard, Northwestern), biopharma, government, and non-human verticals. No other instrument, including mass spec, can sequence the protein at single amino acid resolution, and no other instrument recognizes the full array of 20 amino acids. Faster, more accurate, and able to work with smaller protein fragments than mass spec. For all intents and purposes, Proteus is the next generation upgrade for the 14K installed base of mass spectrometers in the US. Will everyone upgrade on day one? Of course not. But between market expansion and legacy upgrades, there’s an opportunity to capture significant marketshare.

$QSI Just to put things into perspective.l bought qbts warrents at 23.6 cents,new technology that is far behond my payscale just like QSI is,but held on to it because of new tech,again QSI is cutting edge that it appears no one else has or is even close to having.Anyway long story short l sold qbts for $37+..Not saying it will happen with QSI,but it could..Know what you own.

$QSI 14% intraday swing into the green, on a day when all three major indices were down. That is some solid relative strength. The price action strongly suggests the proteomics category is starting to show up on the market's radar. Both $QSI and $NAUT, two of the only pure play proteomics names, have caught major bids in the last week. QSI is, by far, the better name of the two. But a rising tide lifts all boats and the tide appears to be rising quickly. From the perspective of institutional investors, AI and quantum computing are both crowded trades at this point, so proteomics may be where they look next.

$QSI Close above $1.50 means I am having a drink today, and most likely tomorrow and Sunday as well. You can take my word on that.

$QSI Read my lips, their cash runway extends to Q4 28. They have zero debt. THEY'RE NOT DILUTING DOWN HERE. People need to read the actual filing before posting this nonsense. Company makes it clear in the filing that the instrument mix was designed as a poison pill to prevent QSI from being taken over for pennies on the dollar. This is very common by the way. Even mega caps with tons of cash on the balance sheet and huge cash flows frequently maintain a large shelf for exactly this same purpose.

$QSI I don’t know if you all remember, but I said this is another 2021 SAVA. It went from virtually nothing to 122 pps in a day. When this shows some form of active function that’s what will happen here.

$QSI Average full day volume~ 4.5 -5.0M. Have already traded more than a full days volume. Imo, this is not casual retail buying flow. Institutional repositioning, liquidity algos...Given bond mkt closed, this is not a sleepy session. Tape is alive and imo under accumulation.

$QSI $NVDA fruits of collaboration finally becoming apparent as investors look downstream from their AI chips 20 Amino Acids very soon by year end! Next known catalyst.

$QSI Just a thought,but one more day and we are back in compliance with Nazdaq rules..that alone could epic..Peace Out.

$QSI today's dip took out most if not all of the penny flippers, don't be shocked when moves to $3 very quickly.

$QSI is on fire, up nearly 90% this week with aggressive call buying leading the charge The action is wild with a 4,402-contract Nov 20 $1.50 call sweep at the ask on InsiderFinance showing some serious upside positioning Over the last five sessions, it’s been all call flow, 100% That’s 5,102 sweep contracts and options volume up 251 times IV is flying high between 130 and 180% which screams high volatility and gamma sensitivity in that $1 to $1.50 range The interim Proteus data is a key driver here with performance gains and a Q2 2027 commercial launch target keeping the hype alive But watch out, any slip could change the game

$QSI The real move of the day might start soon. If the platform proves itself Quantum-Si has the potential to become the next illumina in the protein space. The main contender, Encodia ceased operations in January 2026. Take a look at the ILMN chart from the early 2000's. Long hold.

$QSI I just love the performance over the last 3 days on solid news release. Risk reward is still very good. So delighted for anyone who has believed in this stock .

$QSI Fascinating price action and volume—even the name! Let's see if this is just a quick pump or if it's got real legs.

$QSI Just here waiting patiently for the big payout..Its called an investment not instant gratification.And if l agreed with you then we'd both be wrong.

$QSI All this is, is a little breather on the daily chart. It was bound to happen before the next big spike. Still looks solid....
