Position Limit

  

Categories: Derivatives

No, this is not a kama sutra thing.

Some investment funds have limits on exposure, like, "You can't have more than 10% of the fund exposed to telecommunications stocks," or "You can't have more than 20% of the fund in bonds or cash at any time; you have to be fully invested."

There's a given investment position that is limited by the charter or indentures of the fund itself. So you really wanted to make GE a 25% position at $9 when you thought it was going to $20 next year...but you couldn't, because your fund has a position limit.

Sorry, Charlie. Bring other good things to life.

well rather than throwing your money against the wall to

01:01

see what sticks you could use extensive elaborate data to

01:04

determine the best way to maximize your returns depending on

01:08

how much risk you were willing Teo you know risk

02:10

Yeah all right Well in general mpt skews toward less

02:13

risky investments but it all comes down to risk reward

02:17

Tolerance in the end if for whatever reason you feel

02:20

supremely confident that radio shack is about to make a

02:23
