It tells you something about how much a gambling place the market is when a site like this has a one day default for the price change. When it comes to a high level view of the market, why would I care for a comparison of todays prices to ... YESTERDAY??
My first reaction was to look for a 10 year option. There is none, so I took the 5 year option. All of the big names roughly doubled or tripled over the last 5 years. Amazon lagging a bit behind. I could start to reason about the numbers but .. 5 years is just too short. I would play with it more if there was a 10 year option.
And I would love Love LOVE a European version of this.
Because earning 10% in passive index funds over 20-30 years will not make you rich.
Subtract taxes and inflation, and you’re at low single digit returns.
The average tech person “gambling” with stock picking will have the same quality of life as the passive index fund investor.
However the gambler has higher chance at generational wealth. The index fund investor does not.
And a symmetrically higher chance of ruin, and in the process the "averaged out" gain might actually be worse than the index investor after taxes, fees, and inflation are factored in.
Most average investors would be happy with guaranteed single digit returns, however boring.
Treeviews are pretty common views for traders trying to get into new markets. Just like a software engineer understands that the backbone of our networks is retries and waits, traders will create funds that smooth over this kind of daily volatility for people that just want to have their capital appreciate. Imagine explaining to a non software engineer that actually things on the internet are failing all the time and turning them off and on again (retries) is actually how we make sure it all works ;) (and obviously the math that underpins it all is pretty much the same. Networks and markets run on RVs and time-series.)
There is undoubtedly European versions of this btw. If I get around to it after work I'll try and post some.
Real returns are expected to be in the 2-8% range which means that most people should be looking at timeframes around 10-50 year. Unfortunately at that range the money printing has a real impact so the chart needs to be adjusted for inflation and, realistically, changes in the money supply [0] and so it is more work for the implementer.
[0] If it hasn't gone up 33% since 2020 it probably lost value in real terms.
I guess that’s just Comcast and Disney, since Paramount went private, and WarnerBros is about to also.
Tesla is an automobile, solar and robotics company.
Facebook is a media company.
Google is a highly diversified media company.
The list goes on and on...
Fun fact: Goldman Sachs spends $1.9B on technology ever year. Palantir spends about $1B (if you add COGS/Infra + R&D).
I use it all the time and its one of my favorite ways to visually see what is happening.
IOW, I don't expect people's 401K to dip below what it would have been had the AI bubble never existed.
A few suggestions: 1) Sector/subsector drill-downs (AI, cloud, semis, autos) so you can zoom into sectors/clusters 2) Hover/tap cards with basics like revenue, P/E, EV/EBITDA, or YTD return 3) AI “explanations mode”: tap a ticker -> auto-generate a 1-sentence summary of why it moved today (“AMD up 3%: fabs reporting stronger wafer starts; NVDA sympathy move”)
Congrats on the ship @krkb :)
