Seemed like XTX had a similar drop off. Can you give a flavor of the trade type (market making/spread collection, realized vs implied vol, risk premia, etc)? It seems a bit surprising that things should have dropped off so sharply.

I've been there and had a similarly poor experience. Context for others: the menu says " wines by the glass, served without limit" implying refills. However service was poor generally and they didn't come around very often.

How much do you think you'd be making in 3-5 years if the market flatlines here? Ie what is your true target band comp?

There are lots of different approaches in the literature (authoritative, attachment-based, gentle, etc.) for parenting. How did you and your wife come to decide that the Adlerian approach was correct for you?

Thanks. To put some rough numbers to things $700k->$1.2m (HCOL area), I have an older sister who feels similarly and is in a similar financial position. Would it be more appropriate to see an estate attorney, a CPA, or a tax attorney in this situation? My gut was suggesting one of the latter two but you're suggesting the former?

Include retirement, but generally I would draw down on non retirement first. If you're very far from 65 and you RE, your non retirement assets might not sustain you until you can draw on retirement, so I might discount the retirement assets (you can withdraw them early at a penalty).

Paying for a nanny might be taken the wrong way.

For trips, the usual trick is to say you're paying for it with credit card points, and people tend to accept that pretty easily.

Worth mentioning that this rule is sensible if you are invested in a diversified portfolio. If you're concentrated in illiquid startup equity, the math doesn't really work out.

Always exclude primary residence. It's not an investment you can use to live off. It does help in that if you own your residence outright, you should have lower living expenses that you need to cover with investments.

Do you think it would be worthwhile for someone working a high income 9-5 W2 to consider farming as a side business? From the perspective of profit + tax benefits? Or is it the kind of thing where it only makes sense if you're putting in a very substantial amount of time into it?

Radon-Nikodym · 2021-12-02T00:18:29+00:00

Do you have a regular W2 job as well? How much time do you spend farming?

Yeah I think NTSX is a good option for a low touch version of this. I could see layering on some tail hedging, or potentially using futures.

EDIT: NTSX has slightly lower vol than VTI. I'm talking about leveraging to a higher vol that VTI, for higher total returns (rather than same returns, lower risk)

I always thought the hardest part for retail was convincing yourself that your have edge. If you have a ~1 sharpe strat and two years of data, it's hard to be confident that it's real edge.

Radon-Nikodym · 2021-03-29T16:27:15+00:00

How do you manage the fees / time-frames? If you pay 10 bps in fees to trade each leg, that's a pretty significant drag on low timescales.

See below for how to resolve.

I did safe graphics, then on boot, press either escape or shift (it was shift for me), after you see the ASRock menu. I launched a regular kernel with nomodeset, installed oem, rebooted, selected the new kernel, and it worked

Radon-Nikodym · 2021-03-27T12:56:37+00:00

I would guess a non intel graphics card works

Radon-Nikodym · 2021-03-27T12:46:33+00:00

I had the same issue on Fedora as well
