"every generation does not need to learn the ravages of war."

Would not be so sure of that. I suspect the "great generation" has a lot better understanding about the value of peace than more recent generations.

It would likely only work if the instrument being invested in was small and illiquid (i.e., that pumping it up would actually move the price). Otherwise it would be a waste of time.

I've really only heard of this in penny stocks which are illiquid.

This would not work in liquid markets like rates, fx or equity indexes.

I'm pretty sure this isn't true regarding gold. I.e., that some firm has a lot it wants to dump and then spends money convincing people to invest in gold.

Gold is liquid, and the vast majority of it is not held for investment purposes. That is, even if you convinced some people to invest in it, it would not matter much regarding the price.

And consider the costs involved in getting people to actually consider and then act on this recommendation?

But if you have a reference link that refutes this, please provide it.

HFguy··on The Apple $2T Economy
Why this is right? You just responded with a list of their product lines?
HFguy··on Scientists are working to bring the woolly mammoth back
Good thinking!!!
HFguy··on Huawei reportedly building 'secret' semiconductor fabs
Dell???

Agree on Intel, MS, Boeing. And there are others.

But how is Dell strategic?

HFguy··on AI predicts certain esophageal and stomach cancers three years before diagnosis
While paper is paywalled, it doesn’t sound that sophisticated.

The blurb mentions the prediction requires a couple of measurements that aren’t usually taken like stomach and waist circumference.

From my experience with building models (in other domains), the key to break through is very often new data that previously wasn’t considered as it wasn’t easily available.

HFguy··on AI predicts certain esophageal and stomach cancers three years before diagnosis
“When early detection occurs, patients can take additional steps to help prevent cancer.”

Blurb doesn’t say what those are. Paper is paywalled.

The extra data points as inputs into the prediction are things like waist and stomach measurement. So suspect one thing is weight loss.

HFguy··on McKinsey: Yes, you can measure software developer productivity
Disagree. I’m exMck too. Whether senior person wrote it is irrelevant. Just ask whether it is good or bad advice. Lots of smart mid-level people (and some not so smart). And some senior people really good and some are not. My view is it is all about the particular person.

I’ve since been responsible for tech teams as leader of larger businesses.

My take is it seems basic but sensible.

HFguy··on All of Physics in 9 Lines
Not a physicist.

How would someone go from these to maxells equations?

Wondering just how big a leap is required?

HFguy··on The New York Times attacks e-bikes while ignoring the real danger all around us
What the poster is saying is objectively true. At least in NYC. I would add they are particularly dangerous to pedestrians.

Whether the poster has previously slow rolled through a stop sign or cars are dangerous to bikes are separate points.

I would say e-bikes are not the root problem. They are fine. It is the drivers not following any rules is the primary problem.

HFguy··on American universities have an incentive to seem extortionate
Because why???
HFguy··on Serotonin booster leads to increased functional brain connectivity
My experience is quanty people (I'm one also) have too much confidence in their answers.

To make good predictions, you need to make good estimates AND understand what your confidence in your estimate should be.

HFguy··on Serotonin booster leads to increased functional brain connectivity
FWIW, I work in finance and often listen to Hackernews discussions on finance and investing. It is often some horrendously bad takes.

I then have the thought, "Am I doing this in areas where I don't have much experience?".

I can only assume there are some pretty stupid thoughts bouncing around my brain.

HFguy··on A Tradecraft Primer (2009)
Probably for the best.

Don’t really want your various 3 letter agencies operating apart from elected leaders.

HFguy··on When markets melt down, these traders cash in
A fixed allocation to a one-size-fits-all tail risk fund doesn't work. It won't have positive returns over the long run. And its diversification benefit will not be enough to overcome the drag on performance.

A tail risk strategy that is tailored to the portfolio, point in time, in an opportunistic way (e.g., when vol is cheap) can potentially work. But you need a strat like that to be part of the portfolio construction process.

I dont believe that is what they are doing.

HFguy··on War Is a Racket (1935)
Hasn't 2000 Mules been debunked multiple times? It is basically "election was stolen" nonsense. Why do you think it is true?

HFguy··on Nvidia Short Sellers Lose $2.3B in One Day as Stock Soars
Does anyone know how tied OpenAI is to CUDA? I would imagine it is not locked in. Seems like that would be an easily avoidable mistake.
HFguy··on Nvidia’s Blowout Forecast Sparks $260B AI Rally
You can argue that this PE, at this market cap implies, it will eventually have the world's largest market cap (larger than apple...maybe 2X).

Would think OpenAI and others would tire of buying chips from NVIDIA at some point well before that and make their own (like Google does).

HFguy··on This time, it feels different
This is true only if you look narrowly at developed countries. If you look more broadly, a tremendous number of people have had huge increases in income in places like China.

That might even be related (i.e., wages for workers are being depressed in developing world as workers see competition from other workers in developing nations). And capital owners benefiting from increased availability of labor.

TBC, agree that gini coefficient re: wealth in developing world is increasing.

"Consequently they cannot generate and recognize matching brackets correctly."

Can you expand on this? Not quite following.

HFguy··on Federal Reserve pushes interest rates above 5% for first time since 2007
They have a mandate to do sensible things. And a massive 2nd round of additional fiscal stimulus was not sensible.

Additionally, fiscal policy is little slower or more crude than monetary levers. They could be part of the solution.

But putting on the breaks is not going to get them elected.

So we have the Fed who get to be the bad guys.

HFguy··on Fire Sale: $300M San Francisco Office Tower, Mostly Empty
There are a ton of issues. For example, plumbing is very expensive. And in office towers, plumbing is typically run only to service bathrooms near the core of the building. Not bathrooms and kitchens spread all over the floor plan.

HFguy··on Frank founder allegedly defrauded JPMorgan out of $175M hit with federal charges
I think the author is just talking like they normally do.

There is generally a lot of jargon and acronyms used here. All the time. Just that most of it is regarding programming/development, so people don't notice it.

Also, even if they were spelled out, you'd still need to google the term to understand what it means. I.e., LOI and "Letter of Intent" are still just tokens that represent a concept.

HFguy··on The secret joke at the heart of the Harvard affirmative-action case
Legacy at top schools means if your parents went there, you are fast tracked to admissions. It matters a lot. More than test scores.

If you are in that group, you have way higher chance of admission. TBC, you still need high test scores.

The point here is that good test scores and grades prob won’t get you in today unless you are legacy or a preferred group.

HFguy··on How Silicon Valley Bank Avoided Oversight
How would this explain...that vast majority of banks were not doing what you say they were incentivized to do?

Maybe they weren't?
