What are the disadvantages of using a small leverage?
The major drawback to borrowing to invest (i.e. using leverage) is that your return on investment must be high enough to overcome the cost of finance. The average return on the S&P 500 is about 9.8% (from CNBC) a typical unsecured personal loan will have an interest rate of around 18-36% APR (from NerdWallet). This means that on average you will be paying more interest than you are receiving in returns so are losing money on the margin investment. Sometimes the S&P falls and over those periods you would be paying out interest having lost money so will have a negative return! You may have better credit and so be able to get a lower rate but I don't know your loan terms currently. Secured loans, such as remortgaging your house, will have lower costs but come with more life changing risks. The above assumes that you are getting financing by directly borrowing money, however, it is also possible to trade on margin. This is where you post a proportion of the value that you wish to trade with as collateral against a loan to buy the security. This form of finance is normally used by day traders and other short term holders of stocks. Although the financing costs here are low (I am not charged an interest rate on intraday margin trading) there are very high costs if you exceed the term of the loan. An example is that I am charged a fee if I hold a position overnight and my profits and losses are crystallised at that time. If I am in a losing position at that time the crystallisation process and fee can result in not having enough margin to recover the position and the loss of a potentially profit making position. Additionally if the amount of collateral cash (margin) posted is insufficient to cover the expected losses as calculated by your broker they will initiate a margin call asking for more collateral money. If you do not (or cannot) post this extra margin your losing position will be cashed out and you will take as a loss the total loss at that time. Since the market can change very rapidly, such as in a flash crash, this can result in your losing more money than you had in the first place. As this is essentially a loan you can be bankrupted by this. Overall using leverage to invest magnifies your potential profits but it also magnifies your potential losses. In many cases this magnification could be sufficient to lose you more money than you had originally invested. In addition to magnification you need to consider the cost of finance and that your return over the course of the loan needs to be higher than your cost of finance as well as inflation and other opportunity costs of capital. The S&P 500 is a relatively low volatility market in general so is unlikely to return losses in any given period that will mean that leverage of 1.25 times will take you into losses beyond your own capital investment but it is not impossible. The low level of risk automatically means that your returns are lower and so your cost of capital is likely to be a large proportion of your returns and your returns may not completely cover the cost of capital even when you are making money. The key thing if you are going to trade or invest on leverage is to understand the terms and costs of your leverage and discount them from any returns that you receive before declaring to yourself that you are profitable. It is even more important than usual to know how your positions are doing and whether you are covering your cost of capital when using leverage. It is also very important to know the terms of your leverage in detail, especially what will happen when and if your credit runs out for whatever reason be it the end of the financing period (the length of the loan) or your leverage ratio gets too high. You should also be aware of the costs of closing out the loan early should you need to do so and how to factor that into your investing decisions.
Leverage increase returns, but also risks, ie, the least you can pay, the greater the opportunity to profit, but also the greater the chance you will be underwater. Leverage is given by the value of your asset (the house) over the equity you put down. So, for example, if the house is worth 100k and you put down 20k, then the leverage is 5 (another way to look at it is to see that the leverage is the inverse of the margin - or percentage down payment - so 1/0.20 = 5). The return on your investment will be magnified by the amount of your leverage. Suppose the value of your house goes up by 10%. Had you paid your house in full, your return would be 10%, or 10k/100k. However, if you had borrowed 80 dollars and your leverage was 5, as above, a 10% increase in the value of your house means you made a profit of 10k on a 20k investment, a return of 50%, or 10k/20k*100. As I said, your return was magnified by the amount of your leverage, that is, 10% return on the asset times your leverage of 5 = 50%. This is because all the profit of the house price appreciation goes to you, as the value of your debt does not depend on the value of the house. What you borrowed from the bank remains the same, regardless of whether the price of the house changed. The problem is that the amplification mechanism also works in reverse. If the price of the house falls by 10%, it means now you only have 10k equity. If the price falls enough your equity is wiped out and you are underwater, giving you an incentive to default on your loan. In summary, borrowing tends to be a really good deal: heads you win, tails the bank loses (or as happened in the US, the taxpayer loses). Investopedia has a nice article on this here The Key benefit looks like better returns with lower capital. The disadvantage is few brokers offering that can be trusted. Potentially lower return due to margins / spreads. Higher leverage and can become an issue. "A ""junk bond"" is one that pays a high yield UP FRONT because there is a good chance that it could default. So the higher interest rate is necessary to try to compensate for the default Junk bonds are used in leveraged buyouts (LBOs) because such deals are INHERENTLY risky. ""Normal"" companies may have 20%-30% debt and the rest equity, so that the company will have to lose 70%-80% of its value before the debtholders start losing money on ""normal"" bonds. But in an LBO, the company may have only 10%-20% equity and the rest debt. Meaning that if it loses that small equity cushion, the value of the ""junk"" bonds will be impaired." "You start with an error.  &gt;a known disadvantaged minority.  This tells me that you buy into the liberal ""no man is responsible for himself"" bullshit. As you probably do not know, the poorest counties in the US are 95% white, but somehow you need to be a fucking minority to fit into your little box.

In adult world we make decisions based on data, not what our social justice handlers tell us are disadvantaged minorities.. Read the links assmunch.   Here is my solution.  1.If you are willing to work and show progress we as a society will support that process. If you sit back and ""woe as me"" because you are a disadvantaged minority you can fuck right off.  2.If you as a regular person want to give them some money or start a charity because you feel bad about things we cannot measure, then fine. Has nothing to do with society owing you a thing. Life, Liberty and the Pursuit of Happiness. Not a check for 50 years, like Detroit and Baltimore.  3.Family and Church support worked pretty well until the welfare society.   **'When the people find that they can vote themselves money that will herald the end of the republic.'**  -------------Ben Franklin" I do this, and as you say the biggest downside is not having a separate account for your savings.  If you're the type of person who struggles with restraint this is not for you. On the other hand this type of account gives more interest than any other type of US Checking or Savings account I've seen, so you will benefit from the interest. "If there's one thing the futures markets don't lack, it's leverage. It's more than even most of the most aggressive investors use.  Trading options might make more sense for some investors, but I can't think of how this would be ""a safer way"" compared to owning actual futures contracts, even at relatively high leverage." "I would say that you should keep in mind one simple idea.  Leverage was the principal reason for the 2008 financial meltdown.  For a great explanation on this, I would HIGHLY recommend Michael Lewis' book, ""The Big Short,"" which does an excellent job in spelling out the case against being highly leveraged. As Dale M. pointed out, losses are greatly magnified by your degree of leverage. That being said, there's nothing wrong with being highly leveraged as a short-term strategy, and I want to emphasize the ""short-term"" part.  If, for instance, an opportunity arises where you aren't presently liquid enough to cover then you could use leverage to at least stay in the game until your cash situation improves enough to de-leverage the investment.  This can be a common strategy in equities, where you simply substitute the term ""leverage"" for the term ""margin"".  Margin positions can be scary, because a rapid downturn in the market can cause margin calls that you're unable to cover, and that's disastrous. Interestingly, it was the 2008 financial crisis which lead to the undoing of Bernie Madoff.  Many of his clients were highly leveraged in the markets, and when everything began to unravel, they turned to him to cash out what they thought they had with him to cover their margin calls, only to then discover there was no money.  Not being able to meet the redemptions of his clients forced Madoff to come clean about his scheme, and the rest is history. The banks themselves were over-leveraged, sometimes at a rate of 50-1, and any little hiccup in the payment stream from borrowers caused massive losses in the portfolios which were magnified by this leveraging.  This is why you should view leverage with great caution.  It is very, very tempting, but also fraught with extreme peril if you don't know what you're getting into or don't have the wherewithal to manage it if anything should go wrong. In real estate, I could use the leverage of my present cash reserves to buy a bigger property with the intent of de-leveraging once something else I have on the market sells.  But that's only a wise play if I am certain I can unwind the leveraged position reasonably soon. Seriously, know what you're doing before you try anything like this!  Too many people have been shipwrecked by not understanding the pitfalls of leverage, simply because they're too enamored by the profits they think they can make.  Be careful, my friend." The only drawback is if you spend more than you can with the new limit and end up having to pay interest if you can't pay the balance in full. Other than that, there are no drawbacks to getting a credit increase.  On the flip side, it's actually good for you. It shows that the banks trust you with more credit, and it also decreases your credit utilization ratio (assuming you spend the same).
