Hi All,

Still very, very new to stock trading but have been doing quite a bit of reading and was wondering why the OPEN value of a stock is not the same as the previous day's CLOSE and have now come across the concept of AHT (After Hours Trading).

So here is my question:
If you trade in NYSE stocks for example whose trading times equate to 14:30 to 21:00 in the UK, how do you guard against the changes your shares could experience overnight?

I assume it is possible to have a good trading day and be up a few % which could disappear (or even reverse) overnight?

I am asking for the scenario where you manage your own stock and do not rely on software or brokers to manage this possibility.

Thanks in advance.

Victor
