After reading some posts here and listening to some investing podcasts the term āmarket correctionā keeps croping up. Could some one explain exactly what this means please?
I understand that it is related to the share price changing but how is it different from just normal fluctuations in price that we expect to see?
Itās just a term for a larger decrease in price of most or all shares.
People been talking about it for years, just ignore it. Nobody knows anything.
Thank you 
I will ignore it when people mention it.
A correction is a 10% fall, it is a very specific circumstance.
In the crypto world an example of when the term was used A LOT
Bitcoin jumped from circa 3k to circa 20k in a few monthsā¦ possibly driven on by the hopes and dreams of the masses thinking their money would just multiplyā¦
At some point some people with lots of bitcoin or lots of people with some bitcoin decided theyād made gains and it was a safe time to sell and take their profitsā¦ this triggered a very quick down turn, so the masses followed and continued the selling and bitcoin was back to sub 5kā¦
So people would say the market corrected itself to a much more fathomable bitcoin price, not supported fully supported by the sheep
Now I have no idea if thatās the correct use for the term but it lines up with Wikipedia ā¦ and Iām one of the sheep 
So I think what people are saying right now is that because the market is and has been for a while very bullish (throw some cash at Tesla or Apple and youād expect it to go up) it mirrors an environment which could experience a correction ā¦ but as said before itās hard to predict these things (well maybe not so much with the last bitcoin fall)
A market correction is a rapid change in the nominal price of a commodity, after a barrier to free trade has been removed and the free market establishes a new equilibrium price. It may also refer to several of these single-commodity corrections en masse, as a collective effect over several markets concurrently.
