If you take a look at 10 or 30 year trends then it's not really that optimistic at all. For instance, Detla Airlines was at 60 bucks a share before things tanked. There was talk about airline bailouts etc.

I bought it at around 20 dollars a share. This was the riskiest stock I purchased as it was theoretically possible they'd completely dissolve. But, at 20 dollars a share Delta should eventually go back up to 60. It might take 10 years for Delta to get back to 40 but it'd still be profit.

Anyone trading on a time scale of less than a few years is basically always optimistic. Buy and hold is generally the safest strategy. And the famous quote is timing in market beats timing into the market. In March you were able to effectively get on both trains simultaneously.

If your bear case is a 10-year recovery to 40 from 20 that's a CAGR of 7.18%, about the same as the long-term average CAGR of the S&P. The difference is that the S&P doesn't have bankrupty risk, whereas airlines do [1]. So on a risk-adjusted basis, that kind of trade isn't too appealing unless you'd done significant research to show that the risk of bankruptcy or a buyout by a competitor at a reduced valuation was unlikely.

While you might have done that kind of research, the article implies (correctly, in my view) that the typical Robinhood user did not. No surprise; that sort of research is time consuming and requires significant familiarity with the industry. Yet airlines, cruise companies, and other risky assets were preferred by Robinhood users throughout the pandemic.

I think they bought those stocks(options) because they knew that of course those industries would be bailed out and thus there would be a huge catalyst event that would increase the implied volatility and thus the profits they make. And the other and perhaps more important factor was that those stocks were simply much cheaper than spy shares, and therefore their options would be cheaper too.

This is exactly the point; be careful of thinking like this. Some of the biggest profits come from being contrarian to the market view.

To me, this is the kind of thinking that justifies today's blinders about it: it basically can never go down for extended periods because people always buy the dip, but also the government will also always support struggling companies if a crisis happens and companies traded on the stock market have no risk to be dissolved.

Essentially that means there's not any real risk to investing now apart from options or penny stocks. I mean, congrats, we might've eliminated risk, but surely something else has to give to support that.

Well, with things like inflation these stocks HAVE to go up. A dollar in 2022 is stronger than a dollar in 2020 so stocks need to AT LEAST outpace inflation to make it worthwhile at all.

Now, government bailouts is a different can of worms and I am not entirely sure my opinion on that. Generally I would have to say I am against it, as it doesn't actually favor businesses that can properly adapt to the markets and new blockers. But, things like dropping the fed rate to encourage consumer spending does seem okay to me.

If we removed bailouts then there would be risk involved. And there is still risks involved in stocks. Not all stocks only go up. Nikola is basically a pump and dump scheme that likely wont be around in 3 years to grow with the rest of your portfolio. Plenty of companies seem flash growth and then equalize down to something more reasonable.

However, in general, if you buy diverse stocks and ETFs or index funds you should only see it go UP over 10-20 years. You will have dips, and you can even have a recession. The people most impacted by dips in stocks are people trying to retire during that retraction period.

What you described seems to be like intuition though. Stocks are high, people can't afford them and they cannot see a lot of growth. When stocks drop you can capture more growth potential for cheaper. So it seems like a natural progression that people would buy back into the markets, thus helping the markets stabilize.

This isn't what the word "inflation" means? Besides inflation is not that high now. (Admittedly, it's not as low as we pretend it is...)

Re:Pandemic Villains: Robinhood by JakeTheAndroid on Thursday December 10, 2020 @05:16PM (#25379524)
Yeah, someone else corrected me here as I inverted inflation in the wrong direction. It doesn't change the logical premise of the strength of money changing is what will motivate increased value in stocks either way.

I was tired and only half paying attention, but I should have vetted this better before posting it. My bad.

Re:Pandemic Villains: Robinhood by jessaustin on Thursday December 10, 2020 @08:14PM (#25381121)
No worries, but I remain unconvinced. There are nations that have seen high inflation, and that hasn't been so good for their stock markets.
Re:Pandemic Villains: Robinhood by lkjaero on Tuesday December 15, 2020 @02:58AM (#25428053)
Low inflation and high inflation are entirely different things, especially if you mean hyperinflation. During high inflation, monetary transactions break down because nobody wants to hold cash. Why would you sell things today if you would be better off selling tomorrow? Business breaks down, and that's reflected in the stock market.

I find it mind boggling that people can still believe so deeply that infinite growth is possible on a finite planet.

Just looking at climate change as one example, in 20 years or so we're looking a serious portion of the planet being uninhabitable. We'll be having trouble producing enough food to feed people. And climate change is just one of the many systemic problems that we're facing.

I find it mind boggling that people still can't believe infinite growth is possible when all it takes is combinatorial explosion from the outputs becoming inputs in new products (CPU -> computers -> AWS -> SAAS -> some app, etc)

Re:Pandemic Villains: Robinhood by sudosysgen on Thursday December 10, 2020 @12:19AM (#25370060)
Sure you can. It's pretty simple. Growth in resource consumption and energy usage in the past 80 years tracked extremely closely to economic growth.

Combinatorial explosion in production possibilities does not mean anything close to combinatorial expansion in possibilities for growth. It's an increase, but nowhere near factorial.

Here's an example. Imagine that you are a barber shop. What advantage does 10 years of computing advances give you? You might be able to save 15 hours in accounting time and lower appointment friction by 20% over phone calls. The expansion in the productive possibilities linked to tech was combinatorial, but even in a period of ten years it barely improved your business.

The truth is that every frontier has a point of diminishing returns. Your point is that you believe that we can iterate on the value - resources front indefinitely. Well, empirical data just disagrees with you. We're at 2% annual growth on average and slowing down, despite increases in consumption, and even less than that when correcting for population growth.

Yes, Malthiusianism is wrong. You can't equate Malthiusianism with the belief that infinite growth is impossible, that's just a total non-sequitur.

We might still see a lot of economic growth left in the future, but it's clear there will be plateaus and it's clear that we are nearing one.

Growth in power consumption of laptops, is falling.

Growth in total material consumption for say cars will fall too, as less maintenance is required for electrical engine vs internal combustion.

Many people believe we've reached peak oil, as demand will decrease. So it's not so clear.

> The expansion in the productive possibilities linked to tech was combinatorial, but even in a period of ten years it barely improved your business.

If you are focusing on one business, there's little change between barbering now and not just 10 years ago, but even 200 years ago. But small changes are enough - even taking appointments online frees the barber time. So there's some growth.

> The expansion in the productive possibilities linked to tech was combinatorial, but even in a period of ten years it barely improved your business.

However, you are missing the 99% of businesses that are impossible with 1800 technology.

This cause growth, and much more than the little growth seen in barbering.

> The truth is that every frontier has a point of diminishing returns

Diminishing returns are perfectly compatible with asymptotic behavior.

> We might still see a lot of economic growth left in the future, but it's clear there will be plateaus and it's clear that we are nearing one

You don't understand (or you do, but don't want to see it): as long as f(yu) >= f(yt) for yu>yt, there's infinite growth.

It may be less and less, if it's asymptotically going to 0, but it will never reach g=0.

Plateaus are fine - just like recessions. Yes, the economy is not strictly increasing with a time granularity that too small. But group years by pack of 20, do a moving average and you'll see a strictly increasing function. g>0 which means infinite growth is possible, even if g may not be to your liking.

Perfect? No. Good enough? Yes!

> This cat is catching downvotes but that Club of Rome thing and (Limits of Growth, which is a paper this group published) is interesting economic stuff

I'm used to downvotes here since facts are not popular (bitcoin ...)

The "infinite growth in a finite world" is a traditional line from the school of thought this Club of Rome started.

However, as you correctly found out in the wikipedia article, it's dubious at best "the forecasts of the world's future are very sensitive to a few unduly pessimistic key assumptions. The Sussex scientists also claim that the Meadows et al. methods, data, and predictions are faulty, that their world models (and their Malthusian bias) do not accurately reflect reality"

I gave a very simple example (combinatorial explosion) that shows how the whole thing is wrong, and why (here, attacking a key assumption) - but there are many many more holes.

It's not really redeemable, after having been proved wrong more than wrong - just like Malthusianism actually.

> It's worth two minutes of reading

Indeed, in just 2 minutes you can notice even more holes - I just pointed to the most glaring one for people used to algorithm.

Hopefully you will not fall prey to ideological arguments based on a castle of cards with such a flimsy base

The latest javascript front end framework sure but fates help anybody who takes investing advice from this place. Reminds me of the infamous r/buttcoin subreddit. On the front page there you can see when the sub was created. From then until now while they were busy being permabears bitcoin's price has exploded over 1000x.

Infinite growth isn't necessarily the concept. While it's somewhat related, there is a bit of a divergence here.

As I said in another comment, stocks will naturally rise at the very least due to inflation. Prices will go up because the value of the dollar goes up, and the companies perceived value is still roughly the same and grew with inflation.

If inflation is on average around 2%, then stocks ideally increase 2% year over year. This can happen to infinity. That's not the same as infinite growth, but it does hit a lot of the same concepts.

Add this to efficiencies over time, expansion of service offerings which might include capturing new verticals, companies have plenty of room for growth.

This is also why people invest into specific stocks depending on their objectives and risk tolerance. Investing in Apple isn't likely to make you a crap load of money today. But, it's fairly stable. It should outpace inflation so it's a good way to save money with a higher possible yield than say a high interest savings account.

You can also apply this to dividend stocks. Some people make their gains off constantly returning dividends even if the stock itself doesn't increase drastically year over year.

And then you factor in that a lot of companies don't have physical products today. So you can squeeze out even more gains because you can have a relatively fixed cost pricing model that scales well. This is more and more common today than 30 years ago.

As for bringing in an externality like climate change, in an ideal capitalistic situation you'd have companies that would pop up that address these issues thus creating value.

But, if we look at these types of existential threats (which I totally believe are real and matter, don't want to twist that at all) they essentially collapse our current economic system. Therefore, literally nothing matters in terms of buying or selling stocks. We will be facing a massive global crisis that overshadows economic gains to the point that the stock market doesn't matter, and fiat currency is largely diminished.

>Prices will go up because the value of the dollar goes up

sorry to nitpick but inflation is the value of the dollar going _down_. if the value of a dollar were to increase, the price of a thing denominated in dollars (i.e. stocks) would decrease (you can buy more with fewer now-more-valuable dollars), ceteris paribus.
