Are leverage/ko products the only reasonable way to trade stocks?
I am assuming you mean derivatives such as speeders, sprinters, turbo's or factors when you say "derivatives". These derivatives are rather popular in European markets. In such derivatives, a bank borrows the leverage to you, and depending on the leverage factor you may own between 50% to +-3% of the underlying value. The main catch with such derivatives from stocks as opposed to owning the stock itself are: Counterpart risk: The bank could go bankrupt in which case the derivatives will lose all their value even if the underlying stock is sound. Or the bank could decide to phase out the certificate forcing you to sell in an undesirable situation. Spread costs: The bank will sell and buy the certificate at a spread price to ensure it always makes a profit. The spread can be 1, 5, or even 10 pips, which can translate to a the bank taking up to 10% of your profits on the spread.  Price complexity: The bank buys and sells the (long) certificate at a price that is proportional to the price of the underlying value, but it usually does so in a rather complex way. If the share rises by €1, the (long) certificate will also rise, but not by €1, often not even by leverage * €1.  The factors that go into determining the price are  are normally documented in the prospectus of the certificate but that may be hard to find on the internet. Furthermore the bank often makes the calculation complex on purpose to dissimulate commissions or other kickbacks to itself in it's certificate prices.  Double Commissions: You will have to pay your broker the commission costs for buying the certificate. However, the bank that issues the derivative certificate normally makes you pay the commission costs they incur by hiding them in the price of the certificate by reducing your effective leverage. In effect you pay commissions twice, once directly for buying the derivative, and once to the bank to allow it to buy the stock.  So as Havoc P says, there is no free lunch. The bank makes you pay for the convenience of providing you the leverage in several ways. As an alternative, futures can also give you leverage, but they have different downsides such as margin requirements. However, even with all the all the drawbacks of such derivative certificates, I think that they have enough benefits to be useful for short term investments or speculation.
