How expensive is it to keep minimal cash at a brokerage?
You're trying to mitigate the risk of having your investments wiped out by fraud committed by your broker by using margin loans to buy stock secured by other, non-cash assets in your account. The solution that you are proposing does not make any sense at all. You mitigate a very low probability/high impact risk by doing something that comes with a high probability/medium impact risk.  In addition to interest costs, holding stocks on margin subjects you to the very real risk of being forced to sell assets at inopportune times to meet margin calls. Given the volatility that the markets are experiencing in 2011, there is a high risk that some irrational decision in Greece could wipe you out. If I were worried about this, I would: If you have enough money that SIPC protection limits are an issue, you desperately need a financial adviser. Do not implement any strategy involving margin loans until you talk to a qualified adviser. "Losses at a brokerage firm due to fraud are insured up to $500,000 per account for securities  by the SIPC (Securities Investors' Protection Corporation), which is the stock market version of the FDIC (that insures deposits). The protection amount for cash is $250,000. That's small comfort to ""big"" players in MF Global. But it does protect ""small"" investors like you."
"One reason is that it is not possible (at Vanguard and at many other brokerages) to auto-invest into ETFs.  Because the ETF trades like a stock, you typically must buy a whole number of shares.  This makes it difficult to do auto-investing where you invest, say, a fixed dollar amount each month.  If you're investing $100 and the ETF trades for $30 a share, you must either buy 3 shares and leave $10 unspent, or buy 4 and spend $20 more than you planned.  This makes auto-investing with dollar amounts difficult.  (It would be cool if there were brokerages that handled this for you, for instance by accumulating ""leftover"" cash until an additional whole share could be purchased, but I don't know of any.) A difference of 0.12% in the expense ratios is real, but small.  It may be outweighed by the psychological gains of being able to adopt a ""hands-off"" auto-investing plan.  With ETFs, you generally must remember to ""manually"" buy the shares yourself every so often.  For many average investors, the advantage of being able to invest without having to think about it at all is worth a small increase in expense ratio.  The 0.12% savings don't do you any good if you never remember to buy shares until the market is already up." @JoeTaxpayer gave a great response to your first question. Here are some thoughts on the other two... 2) Transaction fees for mutual funds are tied to the class of shares you're buying and will be the same no matter where you buy them. A-shares have a front-end 'load' (the fee charged), and the lowest expenses, and can be liquidated without any fees. B-shares have no up-front load, but come with a 4-7 year period where they will charge you a fee to liquidate (technically called Contingent Deferred Sales Charge, CDSC), and slightly higher management fees, after which they often will convert to A-shares. C-shares have the highest management fees, and usually a 12- to 18-month period where they will charge a small percentage fee if you liquidate. There are lots of other share classes available, but they are tied to special accounts such as managed accounts and 401-K plans. Not all companies offer all share classes. C-shares are intended for shorter timeframes, eg 2-5 years. A and B shares work best for longer times. Use a B share if you're sure you won't need to take the money out until after the fee period ends. Most fund companies will allow you to exchange funds within the same fund family without charging the CDSC. EDIT: No-load funds don't charge a fee in or out (usually). They are a great option if they are available to you. Most self-service brokerages offer them. Few full-service brokerages offer them. The advantage of a brokerage versus personal accounts at each fund is the brokerage gives you a single view of things and a single statement, and buying and selling is easy and convenient. 3) High turnover rates in bond funds... depending on how actively the portfolio is managed, the fund company may deliver returns as a mix of both interest and capital gains, and the management expenses may be high with a lot of churn in the underlying portfolio. Bond values fall as interest rates rise, so (at least in the USA) be prepared to see the share values of the fund fall in the next few years. The biggest risk of a bond fund is that there is no maturity date, so there is no point in time that you have an assurance that your original investment will be returned to you. I think this is off topic, but here is a stab: So these are cashless.  It could be a way to smooth out the harsh reality of capitalism (I overproduced my product, I have more capacity than I can sell) and I can trade those good to other capitalists who similarly poorly planned production or capacity. Therefore the market for a system like is limited to businesses that do not plan well.  Business that plan production or capacity to levels they can already sell for cash do not need a private system to offload goods. Alternatives to such a system include: (I don't know how many businesses are really in this over production / over capacity state.  If my assumption that it isn't many is wrong, my answer is garbage.) This is a bartering system with a brokerage.  I think we have historically found that common currencies create more trade and economic activity because the value of the note in your pocket, which is the same type of note in my pocket, is common and understood.  Exchange rates typically slow down trade.  (There are many other reasons to have different currency or notes on a global sale, but the exchange certainly is a hurdle to clear.) This brokerage is essentially adding a new currency (in a grand metaphor).  And that new currency is only spendable on their brokerage, which is of limited use to society as a whole, assuming that society as a whole isn't a participating member of that brokerage. I can't really think of why this type of exchange is better than the current system we have now.  I wouldn't invest in this as a business, or invest in this as a person looking for opportunity. "It's a real pain in the rear to get cash only from a bank teller (the end result of cutting the card as suggested). There is a self control issue here that, like weight loss, should ultimately be addressed for a psychologically healthy lifestyle. You don't mention a budget here. A budget is one of the first tools necessary for setting spending limits. Categorizing your money into inviolable categories, such as:  will force you to look at any purchase in context of your other needs and goals. Note that savings is at the top of the list, supporting the aphorism to, ""Pay yourself first."" Make realistic allowances for each budget category, then force yourself to stick to this budget by whatever means necessary. Cash in several envelopes labeled with each category can physically reinforce your priorities (the debit card is usually left at home for now).  Roll remaining funds from each month over into the next month to cover irregular larger expenses, such as auto repairs.  What sort of investing are we talking about? If you are just talking about retirement savings, an automatic deduction of just $50 to a Roth IRA account at a discount brokerage every pay check is a good start. An emergency fund of 6 months expenses is also common financial advice, and can likewise be built from small automatic deductions. In defense of wise use of plastic, a debit card can be a great retroactive budgeting tool because it records all spending for you. It takes a lot more effort to save and enter receipts for cash, and a compulsive spender without a budget is just as likely to run out of money whether or not he uses plastic. You could keep receipts in the envelope you take the cash out of when you're getting started. If you are so addicted to spending that you must cut your debit card to enforce your budget, at least consider this a temporary measure to get yourself under control. When the bank issues you a new card, re-evaluate this decision and the self control measures you've implemented to see if you've grown enough to keep the card." "Before the prevalence of electronic trading, trading stocks was very costly, dropping from ~15c in the late 1970s to less than a nickel per share today.  Exchange fees for liquidity takers are ~0.3c per share, currently. When orders were negotiated exclusively by humans, stocks used to be quoted in fractions rather than decimal, such as $50 1/2 instead of something more precise like $50.02. That necessary ease of negotiation for humans to rapidly trade extended to trade size as well.  Traders preferred to handle orders in ""round lots"", 100 shares, for ease of calculation of the total cost of the trade, so 100 shares at $50 1/2 would have a total cost of $5,050.  The time for a human to calculate an ""odd lot"" of 72 shares at $50.02 would take much longer so would cost more per share, and these costs were passed on to the client. These issues have been negated by electronic trading and simply no longer exist except for obsolete brokerages.  There are cost advantages for extremely large trades, well above 100 shares per trade. Brokerage fees today run the gamut: they can be as insignificant as what Interactive Brokers charges to as high as a full service broker that could charge hundreds of USD for a few thousand USD trade.  With full service brokerages, the charges are frequently mystifying and quoted at the time a trade is requested.  With discount brokerages, there is usually a fee per trade and a fee per share or contract.  Interactive Brokers will charge a fee per share or option only and will even refund parts of the liquidity rebates exchanges provide, as close as possible to having a seat on an exchange.  Even if a trader does not meet Interactive Brokers' minimum trading requirement, the monthly fee is so low that it is possible that a buy and hold investor could benefit from the de minimis trade fees. It should be noted that liquidity providing hidden orders are typically not rebated but are at least discounted. The core costs of all trades are the exchange fees which are per share or contract.  Over the long run, costs charged by brokers will be in excess of charges by exchanges, and Interactive Brokers' fee schedule shows that it can be reduced to a simple markup over exchange fees.   Exchanges sometimes have a fee schedule with lower charges for larger trades, but these are out of reach of the average individual." "You can move most or all of those financial products into a single account at one institution, but I wouldn't go with a ""mutual fund account"" like Vanguard. The big online brokerages should offer: Consolidating everything into one statement can vastly simplify your record keeping. With a balance of $250k, you should be able to get a paper statement without a fee. Depending on where the accounts are currently held (e.g. if the stocks are at a full-service broker), you may also be able to save on fees." "Yes.  I heard back from a couple brokerages that gave detailed responses. Specifically: In a Margin account, there are no SEC trade settlement rules, which means there is no risk of any free ride violations. The SEC has a FAQ page on free-riding, which states that it applies specifically to cash accounts. This led me to dig up the text on Regulation T which gives the ""free-riding"" rule in §220.8(c), which is titled ""90 day freeze"". §220.8 is the section on cash accounts. Nothing in the sections on margin accounts mentions such a settlement restriction. From the Wikipedia page on Free Riding, the margin agreement implicitly covers settlement. ""Buying Power"" doesn't seem to be a Regulation T thing, but it's something that the brokerages that I've seen use to state how much purchasing power a client has. Given the response from the brokerage, above, and my reading of Regulation T and the relevant Wikipedia page, proceeds from the sale of any security in a margin account are available immediately for reinvestment. Settlement is covered implicitly by margin; i.e. it doesn't detract from buying power. Additionally, I have personally been making these types of trades over the last year. In a sub-$25K margin account, proceeds are immediately available. The only thing I still have to look out for is running into the day-trading rules." Merrill charges $500 flat fee to (I assume purchase) my untraded or worthless security. In my case, it's an OTC stock whose management used for a microcap scam, which resulted in a class action lawsuit, etc. but the company is still listed on OTC and I'm stuck with 1000s of shares.
