Profiting off $0.01 changes in real life?
"You can certainly try to do this, but it's risky and very expensive. Consider a simplified example. You buy 1000 shares of ABC at $1.00 each, with the intention of selling them all when the price reaches $1.01. Rinse and repeat, right? You might think the example above will net you a tidy $10 profit. But you have to factor in trade commissions. Most brokerages are going to charge you per trade. Fidelity for example, want $4.95 per trade; that's for both the buying and the selling. So your 1000 shares actually cost you $1004.95, and then when you sell them for $1.01 each, they take their $4.95 fee again, leaving you with a measly $1.10 in profit. Meanwhile, your entire $1000 stake was at risk of never making ANY profit - you may have been unlucky enough to buy at the stock's peak price before a slow (or even fast) decline towards eventual bankruptcy.  The other problem with this is that you need a stock that is both stable and volatile at the same time. You need the volatility to ensure the price keeps swinging between your buy and sell thresholds, over and over again. You need stability to ensure it doesn't move well away from those thresholds altogether. If it doesn't have this weird stable-volatility thing, then you are shooting yourself in the foot by not holding the stock for longer: why sell for $1.01 if it goes up to $1.10 ten minutes later? Why buy for $1.00 when it keeps dropping to $0.95 ten minutes later? Your strategy means you are always taking the smallest possible profit, for the same amount of risk. Another method might be to only trade each stock once, and hope that you never pick a loser. Perhaps look for something that has been steadily climbing in price, buy, make your tiny profit, then move on to the next company. However you still have the risk of buying something at it's peak price and being in for an awfully long wait before you can cash out (if ever). And if all that wasn't enough to put you off, brokerages have special rules for ""frequent traders"" that just make it all the more complicated. Not worth the hassle IMO."
I think what's screwing up my calculation is the (reL), return on equity levereged figure. The beta for KORS apparently is -0.58, so when I use the formula reL = rf + (ßL)(rm - rf), I get -0.0048 as my reL.   Am I doing my beta wrong? Am I supposed to use a different figure for my beta?    ALSO, further in the process, when using the formula for WACC, my E/(D+E) is essentially 1.0 because market value of equity for KORS is 7bill and its market value of debt is only like 147 million.  edit: I'm beginning to believe that my beta of -0.58 is not rightly used. It's what yahoo told me, but other sources are saying that the beta of KORS is more like -0.01 or close to 0. Yes?   edit 2: Using -0.01 beta, I get a rdWACC of 2.2%. Now this seems more plausible. I did some research on negative betas and found out that they basically don't really exist aside from gold. So Yahoo must be giving me a weird beta figure. Other websites are all giving me -0.01, so I believe that is correct. Your desire to travel before starting work is smart and something you should do. There are very few opportunities in life where you will have a chunk of time to do such travelling. Having said that, your life plans may or may not pan out the way you expect. Ideally, you'd take the 0% APR for 18 months and max it out. A 3% balance transfer (BT) fee breaks out to 1.5% APR, but due in 1.5 years. That's a very good loan rate if you can pay it before the APR changes. Say, you take 6 months to travel. When you return, you have one year to pay off your credit card bill. Calculate how much you will borrow and how much your monthly payments will be. $1,500 across 12 months is $125. Can you add that as a monthly expense? What will your life circumstances be when you return from travel? Do you know what your income will be? Do you know what your expected expenses will be? How much padding will you have for emergencies? You'd need millions of dollars to trade the number of shares it would take to profit from these penny variations.  What you bring up here is the way high frequency firms front-run trades and profit on these pennies. Say you have a trade commission of $5.  Every time you buy you pay $5, every time you sell you pay $5.  So you need a gain in excess of $10, a 10% gain on $100.  Now if you wanted to trade on a penny movement from $100 to $100.01, you need to have bought 1,000 shares totaling $100,000 for the $0.01 price movement to cover your commission costs.  If you had $1,000,000 to put at risk, that $0.01 price movement would net you $90 after commission, $10,000,000 would have made you $990.  You need much larger gains at the retail level because commissions will equate to a significant percentage of the money you're investing. Very large trading entities have much different arrangements and costs with the exchanges.  They might not pay a fee on each transaction but something that more closely resembles a subscription fee, and costs something that more closely resembles a house. Now to your point, catching these price movements and profiting.  The way high frequency trading firms purportedly make money relates to having a very low latency network connection to a particular exchange.  Their very low latency/very fast network connection lets them see orders and transact orders before other parties.   Say some stock has an ask at $101 x 1,000 shares.  The next depth is $101.10.  You see a market buy order come in for 1,000 shares and place a buy order for 1,000 shares at $101 which hits the exchange first, then immediately place a sell order at $101.09, changing the ask from $101.00 to $101.09 and selling in to the market order for a gain of $0.09 per share. &gt; (Wouldn't renewable investment be) A positive even if climate change is not REAL?!?!  No, have a look at [the broken window fallacy](https://en.wikipedia.org/wiki/Parable_of_the_broken_window).  Regardless, there is no reason to stoop to this level.  Global warming exists and the evidence is unequivocal.  Anyone who disagrees are profiting from maintaining the status quo or are victims of the propaganda from the former. Line one shows your 1M, a return with a given rate, and year end withdrawal starting at 25,000.  So Line 2 starts with that balance, applies the rate again, and shows the higher withdrawal, by 3%/yr.  In Column one, I show the cumulative effect of the 3% inflation, and the last number in this column is the final balance (903K) but divided by the cumulative inflation.  To summarize - if you simply get the return of inflation, and start by spending just that amount, you'll find that after 20 years, you have half your real value.  The 1.029 is a trial and error method, as I don't know how a finance calculator would handle such a payment flow. I can load the sheet somewhere if you'd like.  Note: This is not exactly what the OP was looking for. If the concept is useful, I'll let it stand. If not, downvotes are welcome and I'll delete. Peer to peer lending such as Kiva, Lending Club, Funding Circle(small business), SoFi(student loans), Prosper, and various other services provide you with access to the 'basic form' of investing you described in your question.  Other funds: You may find the documentary '97% Owned' fascinating as it provides an overview of the monetary system of England, with parallels to US, showing only 3% of money supply is used in exchange of goods and services, 97% is engaged in some form of speculation.   If speculative activities are of concern, you may need to denounce many forms of currency. Lastly, be careful of taking the term addiction too lightly and deeming something unethical too quickly.  You may be surprised to learn there are many people like yourself working at 'unethical' companies changing them within. How should we disregard leverage when it's the leverage that creates the 'wipe-out' potential? If you simply convert 100K EUR to USDollars, you dollars might then fluctuate a few thousand, maybe even 10K over a year, but the guy that only put up 1000 EUR to do this has a disproportionally higher risk. "at $8.50:  total profit = $120.00 *basis of stock, not paid in cash, so not included in ""total paid"" at $8.50: total profit = $75.00"
