On the back of what reddit has done I learnt there's more than "buy low and sell high"
Yes, I did think the stock market was only that. I've learnt that there's borrow stocks, you can earn $xxx for every $x over a share price there is. My head is blown and currently struggling to understand it all.
Short selling is pretty straightforward, wait until you start reading about the myriad various derivatives products
When I was working in investment banks I used to understand it all....but it's been a while now, probably a whole new breed of products these days!
