bubble

An economic bubble is a situation in which asset prices are much higher than the underlying fundamentals can reasonably justify. Bubbles are sometimes caused by unlikely and overly optimistic projections about the future. It could also be described as prices which strongly exceed the asset's intrinsic value.
Bubbles are sometimes referred to as a speculative bubble, a financial bubble, or a speculative mania.
In the early stages of a bubble, many investors do not notice the bubble for what it is. People notice the prices are going up and often think it is justified. Therefore bubbles are often conclusively identified only in retrospect, after the bubble has already popped and prices have crashed.

    Megaflo Air Bubble not taking expansion

    I noticed today that the pressure gauge on my incoming water supply was showing over 5 bar and creeping up fairly rapidly until it went past 6 (that's the max it goes to) and continued. The Megaflo pressure reducing valve should be 3 bar, and this is normally what the gauge shows. The only thing...
