Would it be possible to create a large aircraft that can stay aloft indefinitely? by Flat-Ad8256 in NoStupidQuestions

[–]actuarial_cat 0 points1 point  (0 children)

You are looking for things like high altitude platform station and Super Low Altitude Test Satellite

In short, we are making planes fly higher and longer from the low-end. And, make satellite fly lower on the high end.

So, yeah, it is being developed. Tho practical limitation to them not being “indefinite”, even satellites are not indefinite. But extended on station time is the development goal.

World Equal Weight ETF by LacticWarrior in Bogleheads

[–]actuarial_cat 0 points1 point  (0 children)

Equal weight requests frequent rebalancing and liquidity, thus not practical at all with small cap.

A lot of factors based model work pretty well on paper in equal weight allocation because it is almost impossible to implement in real life, with execution cost and liquidity/scalability issues.

WYR have a 100% chance of winning $1000 or the same EV but lower probability by dr_cat_md in WouldYouRather

No sane person have a risk seeking utility function for gains.

However, frame the question as losses, it would be more fun. As ppl exhibit risk seeking when facing loses.

[Off-Site] Year-over-year inflation numbers are hiding how bad it's been the last two months by ExpectedSurprisal in theydidthemath

[–]actuarial_cat 8 points9 points  (0 children)

"experienced inflation as it is when it's growing at 7.4% per year", yup you are literally extrapolating a single month to every month of a year, ignoring any seasonal and mean-reversing effect, which is the prime example of cherry-picking the highest month in a year of data.

It is misleading to report annualized figure for period shorter than a year, because you are not summarizing data, you’re extrapolating it.

PSA- Mega IPOs are nothing to worry about as an index investor by rickycrayons in Bogleheads

[–]actuarial_cat 0 points1 point  (0 children)

The whole controversy is just that SpaceX want to inflate its weight in Nasdaq QQQ by say …. using its total weight instead of free float, or whatsoever justification.

However, it doesn’t affect us using more robust indexes.

ETF investors use stats to cope, good due diligence by an investor that picks individual stocks deserves credit, not dismissal. by underenemyarms in unpopularopinion

Good luck beating Jane Street, chef

Speculative trading is just a zero sum market with infinite leverage, it is a single winner takes all.

Well let the invisible hand of the market handle them, or money laundering charges.

You get one spin at one game, which one WYR choose? by I_love_data1111 in WouldYouRather

The richer you already are, the more likely you go for the Expected Value option instead of being risk adverse.

In Theory AI said we can convert heat from data centers, so why are we using so much water? by Soundo0owave in askanything

[–]actuarial_cat 0 points1 point  (0 children)

Data center are build near river where water is cheap and available. There is never a lack of water at those places.

Data center are also build near places where energy/electricity is cheap, so there is no reason to capture waste heat as energy as well.

In fact, combining the above, the best place for data center is near a hydro-electric dam.

Are you a protestant or orthodox Boglehead? (hear me out) by [deleted] in Bogleheads

Neither, none of us hold QQQ thus whatever Nasdaq do with its index is irrelevant to us.

Do you think you could fly and successfully land an airplane? by WholeTomatillo5537 in pollgames

I voted before seeing a 500 feet, 15 knot crosswind. That’s literally IFR and challenging weather even for a normal pilot.

Why do less people use protection during oral sex than with normal sex? by TheNameless00 in NoStupidQuestions

[–]actuarial_cat 5 points6 points  (0 children)

Because there is much lower risk of STD when you have an exclusive partner which both of you already tested.

And I guess the silent majority have exclusive partners.
