I don’t think Nasdaq is free float based.

Also, I would be a lot more pessimistic of the index tracking fund managers’ ability or willingness to find extra shares: their goal is to match the index, not beat it. If the index includes the new firm at a blown-up price because everyone sent their buy orders at the same closing auction, then all the index-tracking funds still track their underlying index. They do not care that after that closing auction, the price of the new firm—and likely the index itself—is going to drop.

Do you have an example of an algorithm that learns, rather than is trained/trains itself? I don’t really see the boundary between the two concepts.

I think people were asking you to explain what kind of strategies people run at sharpe 4

One thing is fiduciary duty to the shareholders, another is “pleasing the shareholders” as you describe it. Pleasing the shareholders is necessary only when displeasing them means they will sell the stock when there is no buyer. If there is a buyer, the current shareholders are less relevant — as long as management cannot be accused of not fulfilling their fiduciary duty to them.

If a friend doesn’t give you 4% of their net worth, how can you be certain you are one of their 25 closest friends?

I may be wrong, but I believe spending time in a deeper gravitational well means you observe everything outside of the well to be happening much faster; at the singularity, the entire future of the parent universe will appear to you as happening all at once. There is no notion of “matter that falls in later” — once you reach the singularity, you travel to the end of time in the parent universe. And the passage of time in our universe isn’t a continuation of time in the parent universe; it’s not even the same dimension, the latter is collapsed.

Right--in log scale, the gap has stayed roughly the same until around 1980.

How much do we know about military AI’s capabilities? As in, is there any evidence that the government/military was ahead of big tech on the AI research front?

Presumably, the energy output from a fusion plant (if we ever get there) should be self-sustaining. For starting up, I’m guessing the plant can draw power from the grid itself, no?

So his one eye goes through his face and you see it from both sides. Wonderful

And just a clarification that some (many) ETFs also distribute dividends on a quarterly basis as they accrue them from their holdings, so technically you want to be looking at the total return indices.

Being willing to use them is not the same as being willing to use them first.

I don’t even think this is satire. This feels like the kind of made up stories that children come up with (and place themselves at the center of).
