China owns a ton of US treasuries. It will sell some of those in exchange for dollars. It will then buy it's own currency, the Yuan, with those dollars.
Selling treasuries will make US bond prices go down.
Buying Yuan will increase it's price versus the dollar.
So, this is a move by China to prop up the value of it's currency.
I heard a similar story from a Sony employee about the Sony hack. Was able to find it mentioned in a Vanity Fair article:
>...this morning, as she began her day, she discovered that a bizarre specter had hijacked her computer. The screen glowed with a blood-red skeleton baring its fangs, and the words “Hacked By #GOP.”
>The third reason for why individual options are probably worth less now than they used to be is that both employer and employee need to account for the fact that the time until IPO or liquidity is longer than it used to be. This is a big issue. To get the true value of offered comp, employees need to add their offered salary to the present value of the options offered. When calculating that, the further out the payout, the less it is worth today
This assumes a constant payout, which defeats the purpose of options. If there were a set date and set payout, the company should just offer cash bonuses or similar.
The value of an option increases the further the expiration date is [0]. He even says:
>You can be pretty sure that a company currently worth $10mm won't be worth $1b in 3 months, so you have a reasonable band of expectation.
Sure, but it might be in 5 years. You're granted an option as a bet that it might grow that big by the time you cash out - not to lock in some set amount of compensation 3 months from now.
Maybe I'm missing his point. Sure, employee compensation might need to be rethought - but not because options are a bad tool. Companies grant options at an early stage because of the long time horizon and high volatility [1]. That's what makes them valuable. If you want your compensation to be liquid and predictable, you should probably just ask for more cash.
Most HFT players are market makers, not market takers. If you take a look at the fees in that link, the fees for liquidity taking are positive, i.e. $0.0027, whereas the fees for liquidity providing are negative, i.e. $(0.00150).
Exchanges offer rebates to market makers to incentivize market activity on their platform.

One question I think is worth considering: if the quality of STEM education increased, wouldn't that increase the number of vacancies in STEM jobs per year? Theoretically, more qualified people -> better research -> new companies -> new job opportunities.
Having grown up in St. Louis, I will say that the statistics about violence are highly skewed. Yes, the rates of violent crime in East/North St. Louis are extremely high. However, it's not terribly difficult to avoid these areas (unless you're really into strip clubs). The suburbs and most of the rest of the city are no less safe than comparable areas in the bay area.
