Is it wise to invest small amounts of money short-term?
You can expect about a 7% return when investing in the general market if your horizon is ten years or more. The market fluctuates, which means that you should be absolutely fine with losing 10% or more of your invested money during this period. You say yourself that: I have been setting aside money (...) into a savings account earmarked for that purpose (repairs/maintenance) so that I don't have to take out loans. It's obvious from your question that the purpose of this money is not savings, this is money that you are already investing, not in stocks or bonds but in your house. While this money sits around, of course you could put it into the market and hope that it grows. It all depends on your horizon, which in your case sounds like about 1 year. Is that long enough to be fairly sure you will make a profit? From what I've written so far, hopefully you can gather that the answer is no. If you choose to invest $6,000 but you need that money back in one year, you need to be aware of the risk that you'll instead end up with $5,400 or even less. Your options are then to: If you're asking for personal advice, my opinion would be this: you're already investing in your house. The housing market, like most markets, fluctuate. Whether you like it or not, you're already a victim (or benefactor) of this value fluctuation. The difference is that a house is something you'll live in for a long time (probably), that will give you daily joy in a way stocks and bonds won't. Of course, saving up money and investing them is always a good idea anyway. You should still save a small amount every month and put it into low/medium risk bonds, in my opinion. This is slightly opinion based. Is it appropriate to invest small amounts for short periods of time?  At your age and the time period, I would say NO. This is because although the index fund do return 6-7% on average, there are several times it blips and goes negative as well. Stock Markets in short periods like 6 months can be unpredictable. At times a downturn will remain stagnant for periods of 2-3 years before suddenly zoom ahead. If you are not to particular about the time when you need the changes done; i.e. the changes can in worst case wait for few years; then yes investing in Index fund would make sense.  Else you are well off keeping this in savings. Try CD's if they can offer better rates for such durations. Even straight index funds grow at about 6-7%. on average, or over long periods of time.  In short time periods (quarters, years), they can fluctuate anywhere from -10% to +20%.  Would you be happy if your bank account lost 10% of its value the week before you had to pay the bill for the repairs?   Is it appropriate to invest small amounts for short periods of time? In general, no.  Most investments are designed for long term appreciation.   Even sophisticated financial companies can't do any better than 1 or 2% (annualized) on short-term cash reserves. Where you can make a huge difference is on the cost side.  Bargain with suppliers, or wait for sales on retail items.  Both will occasionally forego their margin on certain items in order to try to secure future business, which can make a difference of 20% or more in the cost of repairs. I would agree with the other answers about it being a bad idea to invest in stocks in the short term. However, do consider also long-term repairs. For example, you should be prepared to a repair happening in 20 years in addition to repairs happening in a couple of months. So, if it is at all possible for you to save a bit more, put 2% of the construction cost of a typical new house (just a house, not the land the house is standing on) aside every year into a long-term repair fund and invest it into stocks. I would recommend a low-cost index fund or passive ETF instead of manually picking stocks. When you have a long-term repair that requires large amounts of money but will be good for decades to come, you will take some money out of the long-term repair fund. Where I live, houses cost about 4000 EUR per square meter, but most of that is the land and building permit cost. The actual construction cost is about 2500 EUR per square meter. So, I would put away 50 EUR per square meter every year. So, for example, for a relatively small 50 square meter apartment, that would mean 2500 EUR per year. There are quite many repairs that are long-term repairs. For example, in apartment buildings, plumbing needs to be redone every 40 years or so. Given such a long time period, it makes sense to invest the money into stocks. So, my recommendation would be to have two repair funds: short-term repairs and long-term repairs. Only the long-term repair fund should be invested into stocks.
Very wealthy people usually have an investment manager who is constantly moving money between investments and accounts. They hold cash (or cash equivalent) accounts for use in a near-term buying opportunity, for example if they believe certain stocks will go down in price soon. This amount can vary from under 1% (for a money manager with no intention of any short-term trading) to over 20% (for a market pessimist who expects a huge price reduction shortly).  In rare cases they will also hold significant cash because of a planned large purchase, but there's almost never a reason for that to exceed 1% of their net worth. Not charging taxes on a money losing investment or business is much more than humanitarian it is common sense. In general money that is used to invest has already been taxed as income or inheritance to the person making the investment so taxing that money again not just the profit would provide a disincentive for people to invest. Which would be bad for economic growth over the medium and long term. As far as taxing a money losing businesses goes, most businesses don't make money in their couple of years and adding further tax burdens would be counter productive because it would provide a major hurdle for people wanting to start a business. Other have already mentioned that the money losing operation likely paid indirect taxes as well. Small businesses provide a majority of the economic growth and innovation. So in short additional taxes on money losing investments and businesses would be both foolish and shortsighted. Closing a credit card decreases your total available balance, which can have a small negative effect if that credit card is a significant portion of your available credit.  If it is not, then it likely will have little impact on your credit in that department. However, the case you explained - get a card, use it for a short while, then dump it - won't have much long-term impact to your available credit, since you will end up with the same amount as you started. The second factor will be the average age of accounts.  This will affect you both in the short and long term, if you've had accounts open for a fairly long time, but won't impact you much if your credit history is fairly short.  Even closed accounts affect the Average Age of Accounts for FICO scores (but not for some other scoring methods such as VantageScore).  If you have only one other account, and it was 10 years old, then opening and closing this decreases your average age of accounts from 10 to 5 years - a significant hit which will not go away for years (10+ years in some cases, though usually 7 years).  This will lower your score some.  If you have had a lot of accounts, though (including things like mortgage, student loan, etc.), this won't have as significant of an impact, and if you had a short history in the first place, it won't hurt you much either. The third factor will be the hard credit pull.  That will have a small negative impact for around six months; so don't do this just before getting a mortgage, but mostly this won't be a significant impactor for you. In the US, the key to understanding the benefits of retirement accounts is to understand capital gains taxes and how they work. Retirement accounts are designed for making investments throughout your career, then after several decades of contributions, withdrawing that money to pay for your needs when your full-time employment has concluded. Normally when you invest money in a brokerage account, if the value of your investment increases, and you sell in less than a year, those investments are considered short-term gains and taxed as ordinary income. If you hold that same investment for over a year, the same investment is taxed at a lower capital gains rate (depending on which tax bracket you are in during that year, the amount due could be up to 20%, but much lower than your regular income tax rate). When you place your money in a retirement account, you are choosing to either pay the tax due on the income when you put it in the account, or put the money in tax free and pay the tax when you withdraw (these are called tax-deferred accounts). When you have money invested several decades, the raw dollar amount increases greatly, but inflation is also reducing the value of those dollars. Imagine you bought some bonds that payed 4% over 40 years, but inflation was 2% during those same years. When you sell those bonds 40 years later, you will owe capital gains on the entire gain even though half of the gain came from inflation. Retirement accounts allow you to buy and sell according to your investment needs and goals without any consideration about whether the gains are short-term or long-term, and they also allow you to pay taxes just once, either when you put it in, or when you take it out, with no worries about whether you're paying taxes on inflated gains. "Sending your money off to do the heavy lifting is just a stylish way to say ""investing"".  He is saying hold back 6 months of living expenses and don't invest it.   Keep it in cash or some cash-like investment (genuinely safe and liquid).  It's good basic solid advice you'll also get from Dave Ramsey, Suze Orman and any financial advisor worth a darn.    While this is good advice, that does not mean all of his advice is good.  A classic con-man trick is to tell you three things you know are true, mixed with a lie they want you to believe.  They want you to think ""I know 3/4 are true so the fourth probably is too.""" You really have asked two different questions here: I'm interested in putting away some money for my family Then I urge you to read up on investing. Improving your knowledge in investing is an investment that will very likely pay off in the long-term - this can't be answered here in full length, pointers to where to start are asset allocation and low-cost index funds. Read serious books, read stackexchange posts, and try avoid the Wall Street marketing machine. Also, before considering any long term investments, build an emergency fund (e.g. 6 months worth of your expenses) in case you need some liquid money (loss of job etc.), and also helps you sleep better at night. What things are important to consider before making this kind of investment? Mainly the risk (other answers already elaborate on the details).  Investing in a single stock is quite risky, even more so when your income also depends on that company. Framed another way: which percentage of your portfolio should you put into a single stock? (which has been answered in this post). If after considering all things you think it's a good deal, take the offer, but don't put a too great percentage of you overall savings into it, limit it to say 10% (maybe even less). "I'm not an expert by any means, but pretty much every source I've seen says that one year is far too short for any sort of real ""investment"".  Most guides suggest that anything less than 3-5 years should stay in no-risk accounts like savings or CDs.  If you need to be sure you get all of the money back after just one year, any sort of market-based investment (e.g., stocks or bonds) is too risky. One option is to buy I-bonds.  You can buy up to $10,000 worth in a calendar year, and 12 months is the minimum holding period.  The advantage of I bonds is that the interest rate is indexed to inflation, so that (roughly speaking) they cannot lose value in real dollars.  Right now they pay 1.94% per year, which is substantially better than you're likely to get with a savings account or 12-month CD.  This would come to $194 if you buy $10k of I Bonds. If you sell before holding them for five years (which you will under your plan) you forfeit the last 3 months' worth of interest.  Even so, your effective rate will likely be better than a savings account or CD.  (Also you could get 12 months' worth of interest if you're able to buy them slightly early and/or postpone your sabbatical slightly so that you hold them for 15 months.) Your other option is to find the best rate you can in a CD or savings account.  Nerdwallet for instance suggests you could get between 1% and 1.1% for a $10k deposit in a 1-year CD, which would be about $100. As you can see, either way your money is not going to grow that much.  You'll be gaining somewhere in the ballpark of a couple hundred dollars at most.  There just isn't a way to earn more than that in one year without some risk of losing principal. (I'm assuming based on your Texas flag pic that you live in the USA. :-)  To buy I Bonds you must be a US citizen, resident, or government employee.)" "Chris - you realize that when you buy a stock, the seller gets the money, not the company itself, unless of course, you bought IPO shares. And the amount you'd own would be such a small portion of the company, they don't know you exist.  As far as morals go, if you wish to avoid certain stocks for this reason, look at the Socially Responsible funds that are out there. There are also funds that are targeted to certain religions and avoid alcohol and tobacco. The other choice is to invest in individual stocks which for the small investor is very tough and expensive. You'll spend more money to avoid the shares than these very shares are worth.  Your proposal is interesting but impractical. In a portfolio of say $100K in the S&P, the bottom 400 stocks are disproportionately smaller amounts of money in those shares than the top 100. So we're talking $100 or less. You'd need to short 2 or 3 shares. Even at $1M in that fund, 20-30 shares shorted is pretty silly, no offense.  Why not 'do the math' and during the year you purchase the fund, donate the amount you own in the ""bad"" companies to charity.  And what littleadv said - that too."
