I just spent a bit of time searching and reading old threads.......
Trading on margin is an excellent way for leverage, I have been using it for decades. However, in light of your questions, I suspect that you need to do a lot more research to fully understand both how it works and the risks.
....... and actually speaking with the lenders didn't seem to be very helpful ..........
That lender is obviously one you do not use if he can't be helpful from the start. I am not trying to be difficult, but could it be you are not asking the right questions of the lender?
1. If I am using my current portfolio as security, how much can I borrow?
Depends on the shares you hold in your portfolio or what other security you put up. Can't help you with the second one but your lender will have a list of the LVRs for the shares you are using for security similar to
this one for the calculation of the loan amount.
2. If I purchase shares with my margin loan, and then wish to sell them for a capital gain; how does that gain affect my loan? Can I take it out and do what I want with it?
Yes, (keep in mind the tax on profits) and as long as it does not reduce the overall LVR of your account to the point it no longer covers your margin.
3. If I were to have, say, a margin loan of 50k, and used only 25k of it; if the value of the stock I owned went down, it would have to go down significantly (ie: more than the 50% of the loan I wasn't using) before getting a margin call?
Depends on the LVRs of the shares you are holding. The
FAQs here may help understand this. Anybody managing their portfolio effectively will never have a margin call because they will have already sold the shares falling too far in price. My view is that anybody subject to margin calls should not have a margin account or maybe shouldn't be trading shares.
4. If the margin loan is secured against the value of my current portfolio, can I still buy and sell the shares I already owned with ease? And how would this affect my margin loan?
Again, this can be calculated from the LVRs of the securities you hold - and should be done so consistently so that you know exactly where your margin account stands at all times. This can be done by a simple spreadsheet. Whether it is with ease or not depends on whether the trading platform you use has a seamless system with the margin lending or the margin lender.
5. Am I only able to purchase stock with the margin loan that are on that lenders list of approved stocks? I think I read in one thread (can't find it now) where someone was saying that you can use it to purchase any stock, just that if it's one that is not on the list that you can't get extra leverage out of it... or something?
You can buy any share you like in your margin account but too many of the ones not on the acceptable securities list can go a long way to negating the benefit of a margin loan.
Chris, I would suggest you do a lot more research so that you fully understand margin lending and this requires a lot more work than asking questions on forums. There are numerous articles you can find on the internet. I have attached one such article.
