Yes there is. First make an empty list:
stock_market = []
Now when you create the instance:
stuff = GetStuffFromTheUserIfNecessary()
stock_market.append(Stock(stuff))
This leaves the new instance in the last position in the list.
When you have done that as many times as you wanted,
to create the stocks in the market, you can do:
for stock in stock_market:
DoThingsWithThisOneStock(stock)

This means your program must be looking for that input.
Either look at thread and threading, or write a simple
loop that gets input, appends a stock, gets more input
if required, does something with all the stocks, and
either loops or terminates. Or some variation of that
like first building the market and then manipulating it.

I honestly cannot tell if your mindset is right or
wrong - I suppose it depends on your definitions
of the two terms.
