Back Up the Truck
What it is:
Back up the truck is slang for bullish sentiment about a market or security.
How it works (Example):
In the transportation world, drivers often back up the truck when they’re getting ready to get a load from a warehouse. Similarly, in the finance world, the term back up the truck refers to a positive outlook on or even the purchase a large quantity of a particular security. Thus, for example, if John Doe is feeling very good about Company XYZ’s prospects and is going to purchase a large position in the company, we would say he’s going to back up the truck on Company XYZ.
