Time to check the hoses and fluids and fire this baby back up. I am sure there have been other additions to the jargon with the onset of the corona-geddon so I thought I would pop in and see if she hums. New readers need an introduction to some of the early entries anyway.
Timing the Market: Attempts to go in and out of the stock market based on news, trends, Fed movements, 10 year bond rates, bad feelings, phases of the moon, viruses, etc. Generally frowned on yet endlessly attempted and written about in these forums. "This time it is different!"
Top: A relative high point in the market which injects fear into market timers as well as average folk. Never the actual top.
IBKR: Interactive Brokers. Currently the cheapest place to get a margin loan if you want to access cash without selling stock. Reference MMM blog posting of January 29, 2021.
Marginability: The bullet proof quality of whatever stock you are trying to take a margin loan against. Proceed with caution, see also "Buying Power".
Wall Street Bets subreddit: A sand box for both the truly stupid and also the incredibly smart and ballsy, some of which attempt to manipulate stock prices by pumping. Hard to tell the difference most days, it is reality TV for investors. Take from it what you want and leave the rest.
So many more, but that is my start.
