Please, don't ever put yourself in the position of having a margin call happen. If that happens to you, you're not trading in a safe way. Never use more than 50% of available margin. (That number is probably high, too.)

In the current market conditions, I recommend Buy-Writes on the best growth stocks (e.g. MELI, PLTR, and SE, or CDNA and ONDS if you want to take on some more risk, or SOFI and STNE if you want still more risk), or buying LEAPS calls that expire in Jan 2024. I only recommend short puts occasionally, when there's strong evidence that a particular (fundamentally strong and not severely overvalued) security is highly unlikely to drop below an already very low price level.

You don't run the tests...Wanna know how I know?
Because first you have to purify the RNA then run an RT reaction, then purify and amplify the cDNA (you can do RT-QPCR in one step with supermixes but you still need to purify the RNA). There is no pineapple juice or interfering substances by the time you get to the RT step.

AMD has two architectures (as does Nvidia). MI200 is CDNA and they are mainly designed for compute (scientific calculations and ML/AI). While their other architecture is called RDNA. Tencent recently announce they are using V620 which are RDNA based GPU for their server farms.

You can use RDNA for compute and I suppose CDNA for graphics, but they are better suited for their intended tasks.

Well lots more than Ryzen only. Datacenters cDNA 2 coming, Exascale supercomputer due this year first of two wins of 3 the Dep of Energy has awarded to use AMD's chips,... then we have Samsung launching AMD's Exynos in a big way this year. .a lot is going on. .then Xilinx's merger with new TAMs coming. .etc...

Right on! What are some picks that have you interested?

There is nothing better IMO than a company that is actively making the world a better place. Check out $CDNA if you have some time. Biotech that I bought into sub $20. They developed a way to monitor transplant hearts via blood test instead of open heart surgery. How cool is that?! They are moving on to kidneys as well!

Check out $CDNA. Talk about a company with products that materially affect quality of life for transplant patients. Used to just be heart transplant monitoring, but they have recently developed/expanded into kidney monitoring as well. Incredible company. Constantly beating earnings and expectations.

AMD launched their Monster 'Instinct MI100 32GB CDNA GPU' just before Q1, so I'm thinking they specifically wanted to highlight their Datacenter sales this quarter, I'm hoping they finally break down Datacenter sales for EPYC and Instinct into their own categories on their Q1 report, everyone has been asking for it, now might be the time.

Appreciate your .02. I really like CDNA as well, and ur right can’t really compare Illumina and Guardant. Back on CDNA though, I love what the company is doing - and being a recent transplant donor myself, I feel a bit of an attachment lol. Something is in the air though, a buyout makes sense. Saw Ark pulled away though, that gave me some pause. I see them as a great buying opp either way.

I interviewed there a few years ago when they were just $40/share. Not a bad company and a lot to look forward too. I wouldn’t compare it to illumina though as that is a whole other animal. (Illumina basically created the liquid biopsy space with their sequencers, running PCR out the door.) But the two founders are ex-Illumina through another buyout so I was hopeful for one here.

It’s a good steady company, but at 15b for diagnostic products, I don’t know how far it can go without some serious pharma partnership or CDx indications. I do prefer CDNA at their price and growth prospects. A buyout at 2-3x current market cap is possible.

By AMD's roadmap, they will release Zen 4 later this year. Supposedly on TSMC 5nm.
Yesterday the rumor was circulated that their Genoa Zen 4 server processor will have a +29% performace boost compared to their current Milan Zen 3 server processor.
Of course those are just rumors, but that's also a huge generational improvement, again.

And before Zen 4 there will be a Zen 3+ this year, combined with the releasse of the AM5 socket and DDR5 support. And there's going to be RDNA 3 and CDNA 2 this year. AMD is going to have another big year.

I work with these technologies on a daily basis and I can say that CDNA is not going to be enough. AMD might compete in that segment at some point but that can't possibly happen until at least 2025. I don't think AMD is after that segment right now anyway

There is no announcement. It just my personal assessment of the scientific data. BioNTech uses an engineered RNA sequence to maximize protein production and drive immune response. this reduces costs but could have side effects if the engineered sequence has off target effects. Moderna uses a natural mRNA sequence to increase protein production (assumed based on their patents) and randomizes the cDNA sequence so the vaccine mRNA is less likely to combine with the virus. They both are safe and effective short-term. What I'm saying isn't a currently proven risk, but if I had to choose between these two amazing feats of science, I'd go with moderna.

Meanwhile if you look at AMD’s pipeline, they have 7nm and 5nm tech in the works, while Nvidia has just planned on releasing 7nm in Ampere.

AMD Epyc processors trumps Nvidia’s server chips and thus AMD is ahead on the Cloud game

AMD is in Xbox and Playstation, set to release Q4

Even though Apple divorced with Intel, but they will still continue to use AMD to provide GPU for their MBP and Mac line.

While Nvidia is ahead in Cuda, AMD has already started on CDNA to compete against Cuda.

AMD still has loads to give. Just my 2 cents.

Verizon is expensive, but I see you also went balls deep on an expensive phone. I usually buy my phones outright and I go middle of the road so they're not cutting edge but also not bottom of the barrel cheap. I prefer vanilla Android and hate all the changes and bloat that different manufacturers add. My past phone progression with price paid has been(from current to older):

  1. Motorola X4 Android One Edition financed through Google Fi 0% interest across 24 months(last payment is next month) on sale for <$250(retailed for $399 at the time) so monthly payment of $10.38

  2. Nexus 5X(LG/Google) financed through Google Fi 0% interest across 24 months on sale for $399(was $449 retail at the time, larger storage option) so monthly payment was $16.67/month for 24 months.

  3. Nexus 4(LG/Google) bought outright for $399

In regard to service, I used to have T-Mobile and used to pay $50/month for unlimited talk text and data. I moved from the East Coast back to the Mid West in 2013 and found that T-Mobile had great service near my work, but horrible service near my house. That was right when Google Fi(known at the time as Project Fi) opened up for beta sign up. I got on the waiting list and got my invite 3 months later. I love Fi because they support both CDNA and GSM networks and leased their tower usage from T-Mobile and Sprint among others. They automatically connect you to the stronger signal so suddenly I had great reception and data speeds everywhere I went. It also supports WiFi calling so I can even make calls in my basement. Lastly the best part for me is that I never use much data as I'm on WiFi almost everywhere I go. They've changed pricing of data a few times over the years but it's always been exactly $10 per GB. And they don't round, so if you use 1 GB and 628 MB your data bill for that month is $16.28 added to your talk and text(which is only $20 per month). So, in that scenario my monthly bill with my $10.38 phone charge would've only been $46.66 which isn't bad considering the phone financing in there as well. Lastly, they now no longer charge for over 6GB per month and from 6GB-22GB there isn't a fee. Once you hit 22GB they will throttle you unless you agree to pay $10 per GB again for un-throttled data. That's pretty much the same as most carrier's unlimited plans($20 for talk/text + $60 data(unlimited but throttled after 22GB for a total of $80/month).

For me personally this plan is great because I average less than 200-500 MB per month since I'm always on WiFi at both home and work(before I got laid off last week) so my bill with phone financing has been usually right around $35/month, and after next months bill that pays off my phone my bill will drop to around $25/month until I decide to get a new phone(I average once every 3-4 years on a phone).

Those PE guys have missed the train. AMD is a growth company with <20% CPU share in desktop & notebook and 5% in data center. Intel has literally no growth for few years and revenue may compress overtime. AMD is backed up by superior TSMC process along with superior architecture on all three platforms datacenter, desktop and mobile.

NVDA had literally no competition from AMD in the last five years in the high end and ultra high end market especially in the notebook and data center market but that may about to change soon as AMD will be launching RDNA2 GPUs for gaming and CDNA for data center (high end GPUs). NVDAs revenue will feel the impact of increased competition.

Give it few months. Its going to come down. Their revenue is still below 2018 peak. This is when they have zero competition in the high end gaming market and little competition in the data center space for last 5 years. This is going to change later this year when AMD launches RDNA2 GPUs for gaming and CDNA for data center.

Genuinely curious, what makes you think AMD is overvalued? It's the company I'm most bullish on by a very significant margin.

2020 earnings are expected to be quadruple 2019's, which alone would bring the P/E down to a sane-ish level. Guidance is an average yearly revenue growth of 20% for the next 5 years. AMD has always matched or outperformed guidance since Lisa Su took the helm. AMD have stated they guide on the assumption that their competitors stick to their roadmaps - Intel has already gone off course since AMD's investor day with Comet Lake-S 1/2 socket being cancelled, meaning they have nothing in the boarder server market to compete with AMDs 64 cores for not only Zen 2 but also Zen 3. I wouldn't trust Intel's roadmap to not slip further.

AMD just paid off over half their debt. All the major cloud providers (AWS, Azure, Google Cloud) have AMD platforms now. A majority of the recent supercomputers are AMD based. Cloudflare swapped to AMD. Around now-ish we should see AMD hardware starting to get certified for enterprise software. The next consoles are all AMD and they sound swish. Nokia is using AMD for their 5G platform at least in part (not many details on this one but they talked at AMD's investor day).

All of the problems with AMDs mobile platform (high chipset idle draw, no LPDDR) have been rectified with Zen 2 - all the leaks point to Ryzen 4000 mobile trading blows with Intel on perf but at a lower power draw and much lower price.

GPU side is dicier. Lack of CUDA is still an issue. Drivers still aren't reliable enough. Miles behind Nvidia on efficiency. That said, they are still gaining market share from Nvidia. Recent updates have improved drivers dramatically, RDNA has been a massive step forward on the efficiency front, and RDNA2 looks to be a similar step again. Splitting gaming and compute into two different archs (RDNA and CDNA) is exactly the kind of move they should be making.

All serious obstacles as I see them (competitive ARM server chips, Intel chiplet design, viable x86 emulation on ARM) are at least 3 years out.

Sorry, should specify. Synthetic construct (cDNA) constructs can be patented, native DNA cannot. Since CRISPR/Cas9 is a native protein/proto-immune system occurring in bacteria the IP surrounding it is a bit sketchy (who was the "inventor"). I'm not saying it can't be done, just that I wouldn't hang my hat (or dollar) on it. See the supreme court decision Association for Molecular Pathology et al. v. Myriad Genetics for more information on this, I expect it will be heavily sighted as precedent moving forward in biotechnology.

I'd have her look into her usage habits and see what tiers she'd fall into. If she uses more than 2GB of data a month, Ting may not be the best option.

My BF and I average 1GB a month, <500 min, and <2000 txts, so our bill will typically be $48 a month. If any of those go up a tier, we'll be ~$60.

As for service, its been flawless so far. BF has been using it for 3 months, myself 1 week, and there hasn't been a single issue.

Also note that they have 2 networks available- GSM or CDNA (I think those are right). You'll have to chose one when you sign up.

> Doesn't the legal definition of gene the important part? Even if gene really means nothing to scientists wouldn't what it means to a lawyer be more important in terms of patents.

I suppose that is correct. However, then the headlines proclaiming victory for the lack of patentability of a human 'gene' turn on quite the absurd use of the noun. If the definition of gene in those headlines is the legal one and not the scientific one - and those definitions differ - then there is quite a bit of misconstruction going on.

Regarding the 'methods' patent. The methods for obtaining cDNA have changed (read, imporoved) dramatically in the nearly two decades since Myriad did their thing. It is now doable by a robot. And there are many other ways to extract cDNA now. Most notably with direct sequencing. You just sequence the stuff. You can also work backwards from a protein sequence if you have it. There is so much prior art in this space it would be quite difficult to defend the process of obtaining a cDNA. The only thing Myriad could have claimed was the process of finding this cDNA - but that's quite a narrow reading of the technology - and was struck down by the ruling.

cDNA is not used for most of the genetic tests (it was back in the day, not anymore). A lot of companies like Ambrygen and GeneDX use gDNA(genomic...i.e naturally occurring) to report the mutations. Hence, its a huge victory.

Edit: My guess is Myraid also uses gDNA, i might be wrong.

theBPPE has a good comment, but it's lacking some science. As a biochemist who is sitting in lab synthesizing some DNA right now behind me, I'll say this:

The ruling is poorly formed. DNA in a human body exists in a kind of obfuscated form for various reasons. When it comes time to actually read it, the body compresses and trims it down to its useful, temporary form (as mRNA). Scientists then copied that mRNA back into DNA. And then patented that DNA.

So there are 3 items up for grabs here:

  • the method for getting a 'gene' (btw, "gene" is about an antiquated term as 'aether' - it was a placeholder science word that makes no sense and has no solid definition in modern science)

  • the sequence of DNA found in the body (which is on the order of 10,000-100,000 bases long

  • the 'cleaned up' sequence of DNA (which is on the order of 1,000 bases long).

The court ruled the method is patentable (but no one cares, as there are many other ways to do it. No one uses or needs Myriad's method).

The court ruled that the natural full-length 'gene' is not patentable (again no one cares, because it's 90% useless. No one ever cares about the actual sequence in the body because it is not a functional unit either for study or for the body).

The court ruled that the cleaned up DNA is patentable. It is technically true that that molecule does not exist in nature. But as others have said the transformation is trivial. But this is the most useful/used form of DNA. In lab I have a freezer full of cDNAs I use in my study of breast cancer. If each of those molecules was patented I'd only be able to afford a very small fraction of them.

ALSO, because the cleaned up form is patented, every time I did some basic experiments I'd likely be infringing on their patents. Though it was a bit tricky at the time (1997), it is now a truly routine thing to pull out these cDNAs. Whole companies exist to trade these molecules.

tldr; 'gene' is a useless word, and 'genes' are not patentable - no one cares. The (natural) cDNA is the functional unit we use in the lab. This was declared patentable. The human sequence for the proteins made naturally in YOUR body was declared patentable. I make hundreds every day in the lab - it's a really weird rendering of the science.

I'm really not sure about the implications of this. Would be interested to hear somebody else who knows more.

It seems to only cover testing and research, since anytime you create a novel molecule (e.g. a drug) it can be patented. If a particular gene were patentable, it would mean that anybody who wanted to test for that gene in any way would need to pay a license fee. It would also mean anybody researching the effects of that gene would need to pay for the privilege. Basically it means you can't patent a gene, but you might be able to patent artificially created products of that gene. And you can't stop other people from researching a gene.

The fact that cDNA is patentable means that tests/research which involve genomic DNA -> mRNA -> cDNA would likely need to pay a license fee. This would cover a lot of research, RNA-seq is a vital research tool and it would be a shame to have it be so constrained.

It also likely means clinical testing can't cut costs by only sequencing an exome instead of the genome. But if you're only looking at a specific genomic region I don't think it's too costly to just sequence the gDNA, so maybe it's not so bad.

I don't know if Myriad holds a patent on the relevant cDNA, my guess would be not. But their patent was expiring next year anyway. So the implications for this company is pretty minimal (unless they hold other gene patents)

Somebody should also tell the supreme court that cDNA is naturally occurring.

If you are talking about non-coding regions of the DNA, sure I guess so? To my knowledge those areas of genes are filled with redundant noise and evolutionary artifacts. But coding regions of genes aren't noise. They need to be VERY precise sequences in order to make the functioning proteins. So yes, maybe through some mutations any relatively short segment you can think of will probably be "naturally occurring" in non-coding regions, but in the regions of DNA that actually make proteins (the money regions, basically) any deviation from the natural code could limit the functionality of or even destroy the protein.

cDNA is the complement to mRNA, which is the complement to DNA with all those pesky non-coding regions (called introns) cut out. Essentially, cDNA is the DNA that is only used for making proteins. This DNA is not "naturally occurring" only because DNA usually has a lot of useless pieces in it, and this process takes those out.

>“We hold that a naturally occurring DNA segment is a product of nature and not patent eligible merely because it has been isolated,”

Genuine question, couldn't any DNA segment have the potential to be naturally occurring?

>The court did rule that synthetically created DNA, known as cDNA, can be patented “because it is not naturally occurring,” Thomas said.

What if the synthetically generated DNA is identical to naturally occurring DNA?

All corporations start with an idea, and that idea defines the "corporate DNA" so to speak. That cDNA determines what endeavors the company will be good at, and what it won't. Just look at Cisco as one example. Whenever they've purchased another company that makes networking gear, its turned out more or less pretty good. All their efforts at improving their networking gear go well. But, let them try to make phones or tablets. Suddenly, failure errupts. It's rare for a corporation to step significantly outside their DNA and have it go well. But, at a certain point in their growth line, they also can't really fail. Lots of places have invested in Cisco VoIP infrastructure, yet it's the lesser of the choices out there. It's as though there's a halo effect, and if a company is successful enough, they can sell bags of poo on reputation alone. Case in point is the success of coffee percolators in the fifties. Percolated coffee basically liquid shit you make at home. People were told how great it was, and so the story goes.

Google has been becoming more and more annoying, constantly bugging me to link things without really giving me a practically compelling reason to do so. Link my google account with my youtube account. Why? Why sign into google at all was my first reaction when they started asking me to. I just come here to search, I thought. I do think the innovative google tools and applications are compelling, and I'd use them more if google would just get the hell out of my way, and not bug me so much.

I'm quite annoyed by facebook bugging me too. I don't go there much mostly because I always feel like they're pushing too hard. It's like the difference between the neighbor grocer and Sam's club, the latter of which gives me a headache, and I don't leave feeling better than when I walked in. Google+ is like that, shoving other people's shit in my face. I'm not saying G+ is altogether bad, but its certainly not altogether good. Google should stick with searching, not try to be someone else.
