For a very short-term trade, I have shorted Interactive Brokers (Nasdaq: IBKR) today.
There is no excuse for their account management and quotation server system being down for the duration of a trading day, which I believe represents their largest reliability failure at least in the past decade, if not ever.
Their trading systems are still active, but this is probably due to the fact that they need them online in order to liquidate customer accounts that are caught on margin in a timely manner and manage risk. I had issues logging into their trader workstation earlier today.
My suspicion is they got hacked. Perhaps now that Spectre and Meltdown are public knowledge, the people that knew about this in advance are trying to “cash in” on this before the loopholes are closed and major system providers are in the race as well.
If this trade works, it will be a high gainer. If this blows over the weekend, the cover will cost a few bucks but it won’t be anything catastrophic. It is the high risk/reward ratio that I typically like for these sorts of trades, even if the desired result doesn’t materialize. There is a significant amount of information which hasn’t permeated to the public on this and when it does hit, the price will probably take a short-term drop.
(Update, January 5, 2018: They got their data server back up around 1:00pm Pacific Time, which corresponded to the closing of the market… very interesting)
