HR gate is a relatively localized phenomenon - almost entirely considered fluff by the markets.

Data: "A company is making its workers work hard. They have bad press."

Questions: "Has anyone been fired/resigned? is there a new policy change which increases wages and reduces money to shareholders?"

Answers: "as of no, no one significant. No policy change, and no significant damage to brand.

Questions: "Is hiring/firing within normal ranges? How long will people remember this?"

Answers: "mostly normal. No impact to EBITDA. People will forget in a month, unless there is a significant miss step. Insufficient support for a policy or legal bill to be raised."

Conclusions: Has happened before, will happen again, with near 0 impact to cash flow. If something happens theres many ways to mitigate damage to shareholders.

In all honesty, this has near nil impact on the market.

Full thing: It might not have moved because of the liquidity of the market. Due to their stock price, people won't generally own lots of the stock, so any sell orders would go through the SOES (https://en.wikipedia.org/wiki/Small-order_execution_system). I'm not sure whether a Level 1 book would include that information, I have a feeling it doesn't. [citation needed]

However, SOES only works for lots of at most 1000 and only on stocks up to a value of $250. Amazon is currently trading at $535.

Occasionally another instrument will be set up that works in parts of the stock, which will be a lot more volatile, so you could buy 1/10 of an Amazon share. Alternatively, people start trading in options on the stock.

So you get the situation where the share price for Amazon looks fine, but the options market dries up or the volatility of derivative instruments is massive.

Stock markets don't respond only to the possible long term effect.
