Trading : how to deal with crashes (small or big)
caveat: remember that complex derivatives can be very bad for your wealth (even if you FULLY understand them). You can buy out of the money put options that could minimize your losses (or even make you money)  in the event of a huge crash. Put options are good in that you dont have to worry about not getting filled, or not knowing what price you might get filled with a stop-loss order, however, put options cost money and their value decays over time. It's just like buying insurance, you always have to pay up for it.
There's really no right or wrong answer here because you'll be fine either way. If you've investing amounts in the low 5 figures you're likely just getting started, and if your asset allocation is not optimal it's not that big a deal because you have a long time horizon to adjust it, and the expense ratio differences here won't add up to that much. A third option is Vanguard ETFs, which have the expense ratio of Admiral Shares but have lower minimums (i.e. the cost of a single share, typically on the order of $100). However, they are a bit more advanced than mutual funds in that they trade on the market and require you to place orders rather than just specifying the amount you want to buy. A downside here is you might end up with a small amount of cash that you can't invest, since you can initially only buy whole numbers of ETFs shares. So what I'd recommend is buying roughly the correct number of ETFs shares you want except for your largest allocation, then use the rest of your cash on Admiral Shares of that (if possible). For example, let's say you have $15k to invest and you want to be 2/3 U.S. stock, 1/6 international stock, and 1/6 U.S. bond. I would buy as many shares of VXUS (international stock ETF) and BND (U.S. bond ETF) as you can get for $2500 each, then whatever is left over (~$10k) put into VTSAX (U.S. stock Admiral Shares mutual fund). "I think it's apt to remind that there's no shortcuts, if someone thinks about doing FX  fx: - negative sum game (big spread or commissions) - chaos theory description is apt - hard to understand costs (options are insurance and for every trade there is equivalent option position - so unless you understand how those are priced, there's a good chance you're getting a ""sh1tty deal"" as that Goldman guy famously said) - averaging can help if timing is bad but you could be just getting deeper into the ""deal"" I just mentioned and giving a smarter counterparty your money could backfire as it's the ""ammo"" they can use to defend their position.  This doesn't apply to your small hedge/trade? Well that's what I thought not long ago too! That's why I mentioned chaos theory. If you can find a party to hedge with that is not hedging with someone who eventually ends up hedging with JPM/Goldman/name any ""0 losing days a year"" ""bank"".. Then you may have a point. And contrary to what many may still think, all of the above applies to everything you can think of that has to do with money. All the billions with 0-losing days need to come from somewhere and it's definitely not coming just from couple FX punters." I've read some great posts on here and either small business or entrepreneur subs re bars and I've heard the complaints from friends of friends. Apparently theft/wastage is rampant so good cash and alcohol controls are crucial. Even if you don't have outright cash theft, letting bartenders get away with free or big pours for bigger tips ultimately gets you the same result. Your manager should know how many pours he's getting from kegs and bottles. If that adds up (it won't) then it could be a lack of business and you need some marketing. But apparently tracking your pours is the key. There are plenty of books and trade publications out there, so if you don't have a bar background, I'd suggest doing some reading or even talk to/hire someone to help you figure it out. It sounds like you have some systemic issues. In the economic cycle we are are going through the crashing of the monoliths - corporate and political - mass extinction events . As far as investment is concerned where the money can be made is with the small to medium sized businesses - progressive evolution - these will pick up the business from the crashed corporates . You are looking for arbitrage, not in real terms, and you may lose heavily. Big banks would suck out all profit before you get a chance to react. There are thousands of algorithmic trading systems in banks, which specifically predict such situations and try to make money from such moves. If you can invest in such a system, probably you can make a killing, else best is to forget about it. Remember that somebody before you has surely thought about it and put a system in place, so that somebody else cannot make money out of it before he/she does. "I (and probably most considering trading) had a similar thought as you.  I thought if I just skimmed the peaks and sold before the troughs, perhaps aided by computer, I'd be able to make a 2% here, 2% there, and that would add up quickly to a nice amount of money.  It almost did seem ""foolproof"". Then I realized that sometimes a stock just slides...down...and there is no peak higher than what I bought it for.  ""That's OK,"" I'd think, ""I'm sure it will recover and surpass the price I bought it for...so now I play the waiting game.""  But then it continues sliding, and my $10k is now worth $7k.  Do I sell?  Did I build a stop loss point into my computer program?  If so, what is the right place to put that stop?  What if there is a freak dip down and it triggers the stop loss but THEN my stock recovers?  I just lost $14,000 like this last week--luckily, only virtually! The point is, your idea only has half a chance to work when there is a mildly volatile stock that stays around some stable baseline, and even then it is not easy.  And then you factor in fees as others mentioned... People do make money doing this (day traders), and some claim you can use technical analysis to time orders well, so if you want to try that, read about technical analysis on this site or elsewhere." "Being long the S&P Index ETF you can expect to make money. The index itself will never ""crash"" because the individual stocks in it are simply removed when they begin performing badly. This is not to say that the S&P Index won't lose 80% of its value in an instant (or over a few trading sessions if circuit breakers are considered), but even in the 2008 correction, the S&P still traded far above book value. With this in mind, you have to realize, that despite common sentiment, the indexes are hardly representative of ""the market"". They are just a derivative, and as you might be aware, derivatives can enable financial tricks far removed from reality. Regarding index funds, if a small group of people decide that 401k's are performing badly, then they will simply rebalance the components of the indexes with companies that are doing well. The headline will be ""S&P makes ANOTHER record high today"" So although panic selling can disrupt the order book, especially during periods of illiquidity, with the current structure ""the stock market"" being based off of three composite indexes, can never crash, because there will always exist a company that is not exposed to broad market fluctuations and will be performing better by fundamentals and share price. Similarly, you collect dividends from the index ETFs. You can also sell covered calls on your holdings. The CBOE has a chart through the 2008 crisis showing your theoretical profit and loss if you sold calls 2 standard deviations out of the money, at every monthly interval. If you are going to be holding an index ETF for a long time, then you shouldn't be concerned about its share price at all, since the returns would be pretty abysmal either way, but it should suffice for hedging inflation." There are a couple of things you could do, but it may depend partly on the type of orders your broker has available to you. Firstly, if you are putting your limit order the night before after close of market at the top of the bids, you may be risking missing out if bid & offer prices increase by the time the market opens the next day. On the other hand, if bid & offer prices fall at the open of the next day you should get your order filled at or below your limit price. Secondly, you could be available at the market open to see if prices are going up or down and then work out the price you want to buy at then and work out the quantity you can buy at that price. I personally don't like this method because you usually get too emotional, start chasing the market if prices start rising, or start regretting buying at a price and prices fall straight afterwards. My preferred method is this third option. If your broker provides stop orders you can use these to both get into and out of the market. How they work when trying to get into the market is that once you have done your analysis and picked a price that you would want to purchase at, you put a stop buy order in. For example, the price closed at $9.90 the previous day and there has been resistance at $10.00, so you would put a stop buy trigger if the price goes over $10, say $10.01. If your stop buy order gets triggered you can have either a buy market order or a limit order above $10.01 (say $10.02). The market order would go through immediately whilst the limit order would only go through if the price continues going to $10.02 or above. The advantage of this is that you don't get emotional trying to buy your securities whilst sitting in front of the screen, you do your analysis and set your prices whilst the market is closed, you only buy when the security is rising (not falling). As your aim is to be in long term you shouldn't be concerned about buying a little bit higher than the previous days close. On the other hand if you try and buy when the price is falling you don't know when it will stop falling. It is better to buy when the price shows signs of rising rather than falling (always follow the trend).
