Are you sure you're thinking this through?
The Fed is actually about to hit the brakes, people are expecting 7 rate increases this year and more next year. The current 30 year mortgage rate is around 3.5%, the median sale price for a house in the bay area is $1.5 million. With 20% down that's $3500 a month for principal and interest. If the Fed follows through and raises rates say 2%, it turns into $5500 a month.
Doesn't do much for affordability.
And if you're thinking prices will fall when rates rise, that's not what has happened in the past. Over the last 50 years, every time there has been an environment with rising interest rates, housing prices have gone up, not down: https://awealthofcommonsense.com/2022/01/will-higher-mortgage-rates-de… So you will be paying a much higher rate on a more expensive house.

>A tale of the worlds worst market timer: https://awealthofcommonsense.com/2014/02/worlds-worst-market...
I see this posted from time to time, but the assumptions are kind of silly. A huge portion of the "miraculous" returns come from the fact that this fictional person was able to put an entire year's worth of salary into the market in one go, 50 years ago. In 1970 the average salary was about $6,000, but he managed to save one third each year to invest?
So, sure it demonstrates the power of compounding. But, to me, an alternative lesson is that you can be an incredibly diligent saver and, through sheer bad luck, have barely enough to retire. I mean, it's not like $1MM in retirement money means "set for life" anymore.

The idea that we've never had a market correction with passive holdings at current levels is accurate. It also was an accurate statement in 2008, and it also applies to foreigners and mutual funds now, both of which have increased their holdings of equities over time and both of which have substantially greater holdings than index funds.

The market is trending will right now we are looking at higher highs. My system suggests it and has been right when everyone was running away from the market in 14/16/18.
You should read the worlds worst market timer [1]. For most people the best way is to just put all their money in stocks. Obviously not just SPY, maybe a world index, SPY and bonds. This way you can sell the bonds if the market drops and use that for living expenses, or to average out the downturn.

"Home prices look remarkably stable when corrected for inflation. Over the 100 years ending in 1990 — before the recent housing boom — real home prices rose only 0.2 percent a year, on average. The smallness of that increase seems best explained by rising productivity in construction, which offset increasing costs of land and labor."

But do you want to invest or do you want to trade? If what you want is to invest your objective should be to get the average of the market as cheaply as possible not beat it. Here are two articles to help you with that:

> A Keynesian beauty contest is a metaphorical beauty contest in which judges are rewarded for selecting the most popular choices among all judges, rather than those they may personally find the most attractive. This idea is often applied in financial markets, whereby investors could profit more by buying whichever stocks they think other investors will buy, rather than the stocks that have fundamentally the best value, because when other people buy a stock, they bid up the price, allowing an earlier investor to cash out with a profit, regardless of whether the price increases are supported by its fundamentals and theoretical arguments.

In short, we are now an army of proofreaders, in addition to readers, interpreters and users/implementers of written material.

I am reminded of the "writing lesson" scene in "A River Runs Through it", pretty obviously reflecting the author's education as a writer.[0]

Well, we don't throw away polished work on the job. The scene is about education. LLM's are uneducated in communicating to readers, compared to skilled writers, and technical writing, especially, is not like summer reading, where nothing really matters but some vague plot…

Could you please substantiate your claims?
This is what I mean and what I do, by always allocating the same amount of savings per year, in good or bad times [1]. You can see how in 2008 such portfolio had a drawdown of more than -50%. Despite that, it performed well above the 8% IRR I mentioned.
Another interesting data point, by investing lump sums of money at the very peak of every market cycle, immediately followed by a massive crash [2]. I believe the IRR in this case is still above 7%, which is absolutely phenomenal considering the horrible investing timing.
If you don't agree, please tell me exactly why I am wrong and why you are right, so I might learn something. I come to HN to read HN-quality comments, not Reddit-quality content. Thank you.

Typically, no. It's been shown time and time again that people cannot reliably time the market. If they could, with leverage you could become the richest person on the planet in a short time.
You have to understand that if indeed people could in general know that the market was going to crash, then people would have already sold, and the impending crash would already have been priced in.
It follows from that, that the current price essentially is our collective best guess at what the future will bring, including any expectations of recessions. Selling beyond that point means you're seeing something that nobody else does, which either makes you a genius (or lucky), or wrong, and the odds are typically not in your favour.
You can find articles on recession indicators flaring up every month for the past decade. Suppose we had no sense of time, and just a sense of the daily weather to track the seasons. A few warm days in a row may indicate summer has landed, or it's just a normal fluctuation, a few weird days as winter turns to spring. And vice versa with cold days. There'll always be some indicators which may signal something bigger, and it could be just noise, or it could be truly indicative. You don't really know until after the fact. And if you could predict it, then it's likely everyone else could, too, and it'd have already been priced in so trying to time the market tends not to work.
This simplifies things a bit, but unless you're close to retirement (at which point…

Highlights from the article:
- More people in the 18-25 years old age group regularly watch and play esports than any other traditional sport.
- A small town in Poland hosted an event this year that was watched live by people from 180 different countries. The audience was 3x as large as it was for the most recent MLB World Series. More people attended this event in person than the last 3 Super Bowls combined.
- The esports audience in Asia is 4x larger than it is in the U.S., so this is truly a global phenomenon.
- One event in a tournament called the League of Legends was viewed by 80 million fans.
- Twitch is one of the streaming services that allows people to view these events. The service already has a bigger audience than CNN or MSNBC. They get more than 15 million daily unique viewers. They’re owned by Amazon (because of course, Bezos was on top of this trend before anyone else).
- The video gaming audience is 5x the size of Netflix subscribers.
- There’s a league called Overwatch which has teams owned by people who already own a professional sports team. This list includes Robert Kraft (New England Patriots), Jeff Wilpon (New York Mets), Stan Kroenke (LA Rams and Denver Nuggets) and Dave Scott (Philadelphia Flyers). The teams cost them $20 million a piece.

> Their rates have gone negative, from time to time.
Nobody disputes that occasionally, real rates have turned negative (Great depression, 1970's, or after the GFC 2011-2013 in the USA, with some countries in Europe even having negative nominal rates). However, predominantly real rates are positive [1, 2, 3 or even your 1], and some of the earlier episodes were arguably caused by the gold standard.
> non-bank institutions who couldn't find a buyer for their Treasuries fast enough to avoid default on short-term debt.
That's a liquidity problem, as you say yourself, unrelated to rates, no?
EDIT: ah, you're refuting the notion that treasuries are safer than cash. Again, though, you could call that a liquidity problem - if you have loads of cash deposited with a local bank, you might not be able to withdraw it all at once, either.

I think this....
> Mr. Dalio returned to run Bridgewater earlier this year after stepping back to a mentor role six years ago.
Is what's driving almost all of his new found desire for a unified AI to run everything.
Here you have a man who by any measure has been wildly successful, he tried stepping back and letting other take over but ended up finding that the team he left in charge didn't make the exact decisions he would have.
If the story ended there it wouldn't be in any way surprising, who hasn't left a team and second guessed the decisions that the new leaders have made.
It turns out that when you are worth 15 Billion one of the things you can do is hire a shit load of AI experts, like one of the heads of IBM's Watson team, to build an AI to make decisions based on WWRDD, "What would Ray Dalio Do"?
Since his first retirement failed, this is his new take on how to have his second retirement go smoother. Just build an AI that bases all decisions on the Bridge water principles that he wrote down years ago.

As an aside, he recently let Tony Robbins publish his ideal portfolio, the all weather portfolio. It's actually a pretty strong portfolio for the average person.

And this was explained to me by Mario Joiner who cracked this puzzle that I could not figure out what the hell happened. That money became everything. What happened because it was not like that in the seventies. In the seventies, it’s how cool is your job? How cool is what you’re doing? If your job’s cooler than my job, you beat me."

Are you saying the average american doesn't have a disposable monthly $100? That is demonstrably false - the statistics about current income and life costs paint the opposite picture: not only Americans but average people all over world are wealthier than they've ever been.
There are inequalities, of course, (like Europeans falling behind) but the Americans are doing very well indeed. So please stop with your propaganda.
