Whether what Bloomberg wrote is true, misleading or false was not the argument I made.
I made the argument that it was possibly part of an illegal, criminal scheme of market manipulation:
- Minutes before the article was published I saw suspicious price action, for example a ~30k shares sell order at 11:30 EDT, possibly a trader taking a short position based on insider information with a market order, which is inefficient but has the advantage of executing immediately. I was still wondering about that odd transaction when the big drop happened.
- Furthermore, both the drop and the "catching of the falling knife" was too fast in my opinion and not characteristic of typical bad news price action: the price dropped about 9.8% from its daily high, just short of the 10% drop level that would have triggered an automatic circuit breaker that bans activist short selling trades for two days.
- The fall gave me the impression of well informed market participants stopping the fall with limit orders, then (possibly) re-shorting the stock at higher levels again.
(Yes, I know about algo trading, and no, it's not characteristic of them to trade on random news in such volumes - most of them are parsing predictably timed economic events that have an uncertain outcome. It's also very atypical of algo trading to offer 2+ million TSLA shares of liquidity to "catch a falling knife".)
To what extent the Bloomberg article was truthful or misleading was immaterial to my argument:
both insider trading and market manipulation are felonies, even if the news was presented in an entirely truthful and neutral fashion.
And yes, I think SEC experts and investigators should take a good look at today's tape and should request identifying information for the trades performed before and after the news, to determine whether any crimes were committed.
