With a multiple Billions$ port, I used to continually have at least 300-400 millions of available H$ to spend... Everything I wanted being already maxed out (as pruchase or short...), so whenever something new was coming, just max it (either way), I have the $$$ anyways...
Now, with the new limits, I finally ended up again with liquidities not always available... So I do have to do some choice, when I want to buy/short some more expensive titles, I have to find and get rid of some other titles I would consider not as good investments... Meaning I do have to think and analyse before some IPO or big switches...
Like I said, fun is back... ;)
