Surprise... occasionally I trade. Sold my new issue shares of Snap at $24.12 today. A quick 40% profit You? Did you buy into this one? Did you even have access to it from your nvestment firm? I'd guess a company like BMO discount broker was not one that said "hey Cat, we have all of these new issue (cheap, low priced) shares, how many would you like?"Are you still holding them?  Or did you miss out on this almost guaranteed 40% + trade? 

Your questions sound as if you do not understand this process.  Not as if. Almost guaranteed to be another help meout and then criticize the answer.

Dodgy you say? Not dodgy at all. 

Only if you don't understand how this works . Dodgy to you  = costly to you . 

A single day +40% would certainly help those looking to maybe eke out an annual 10% return.
