I recommend investors avoid margin altogether. The idea is to invest to build wealth, not to invest and build wealth if you are lucky. The nature of markets is such that use of margin exposes the small investor to things they shouldn't be exposed to. It always seems like those things cannot and will not happen right up until they actually do. These events happen with regularity in every investors life, some more severe than others and all such events have one thing in common: they don't pre-announce their arrival.
<The following is NOT an ADVICE just my personal speculation>
While I agree with need for caution, and fallibility of human judgment, the reality is that cash has negative rate of return, conversely debt has positive return. With margin rates around 1% and inflation 4% one could use margin to buy truck of bricks and still have positive 3% return.
That being said one has to be aware of:
- how much I am paying for margin and is it good deal
- under which conditions margin would be exhausted,
- what margin is spend on - do I stack up the risks,
- automated warning in place when margin cushion is getting thinner, way ahead of margin call,
- viable and tested plan of action when it happens (other source or liquidity, pre-planned tax selling etc)
Two examples of margin use with dramatically different risks:
A - using margin to buy VOO while having a backstop LOC ready and available at a bit higher cost, which is already linked to brokerage account and fund transfer was tested and timed,
B - buying some OTM LCID call because TSLA went up this week and so did my available margin
