Quote from hajimow:
It has happened to me many times but I cannot give up. But when market goes down, everything goes down and diversification makes the account management more difficult when the market melts.
That statement is nothing more than a silly rationalization for being lazy, reckless, and stupid.
FIrst of all, not ALL stocks go down together. And the ones that do drop, go down various percentages, as they may have different BETA's and be in different sectors.
In addition, if your stock does go down, you will likely get a MUCH EARLIER call from your broker informing you, that you're in a margin call you didn't expect.
WHY?
Because brokerage firms often raise the margin requirements of accounts that are overly concentrated, during market downturns.
That margin cushion you think you have, can dissappear in the blink of an eye, if your broker thinks you are over concentrated.
You now have only a matter of hours to come up with additional cash, or they will close a percentage of your trades.
You talk about..... "making account management more difficult when the market melts."
Trying managing your account when you get an unexpected margin call. And if you are not around to answer the phone..... GULP!
