| But on what time scale? Before a few connected entities make a profit or after? |

| The time scale is at least a thousand times faster than necessary for your retirement savings to be safe. The problem of investment companies selling stupidly at 3am solves itself as they either learn or go bankrupt. And the counterparties making money off those dumb moves don't need to be 'connected'. |

| Milliseconds? Any overnight mispricing is going to become an arbitrage opportunity for market makers, hedge funds, and HFT firms...whom will then compete with each other to mine that arbitrage opportunity until profits go to zero, solving the market inefficiency and mispricing problem over time (and by over time, I mean like probably the first few nights and then it stops being an issue forever). In other words, a liquidity-based mispricing that happens consistently every night is going to quickly stop being mispriced since its so predictable. |

| ▲ | pembrook 4 hours ago | parent [-] | | Yes, when you correct a mispricing in markets that is a valuable service and you tend to get paid in proportion to the mispricing you correct (this is why markets work so well, they provide dynamic incentives in a decentralized way). In case you aren't aware, a world outside the US exists on different time zones and also invests in US capital markets. Having 24/7 trading a massive value-add for the entire world who also invests in US companies, which benefits US companies tremendously given they will continue sucking up the world's capital. This is yet another reason why global companies will continue going public in US markets instead of their own. Meanwhile Europe will continue struggling to form a capital markets union over the next 50 years while they slowly translate legal documents back and forth to each other in 42 languages, growing the fine dining economy of Brussels more than their domestic economies. |

| If you're not trading overnight and there's a flash crash that corrects itself overnight... it's the people who are trading overnight taking money from each other. |
