The spring has been streteched by gravity, with the energy from the extension stored in the spring. It makes sense that the potential energy in the spring balances the downward force of gravity until the top "catches up". Based on that hypothesis, I have two other testable ones. The first is if you extend the spring past its gravitational relaxation, the bottom will move up when you release it. The second is if you compresses it up from its relaxation point, the bottom will fall down.
