what is unlimited risk 
unlimited risk refers to a situation where there is potential for unlimited losses on a trade or in a particular investment in practice unlimited risk would be practically realized as a total loss or bankruptcy moreover positions that have unlimited risk can be hedged using other market instruments understanding unlimited riskany time an asset s price can move indefinitely against a trader s position means they are facing unlimited risk a short trade is an example of a strategy with unlimited risk while unlimited risk trades theoretically have unlimited risk the trader doesn t actually have to assume unlimited risk they can take steps to limit actual losses such as hedging or setting stop loss orders unlimited risk is the opposite of limited risk with unlimited risk there is the potential to lose more than your initial investment which is possible in short selling in trading futures contracts or when writing naked options risk itself refers to the probability that an investment will have an actual return different from the return that the investor expected risk ranges from losing some of one s investment to potentially losing the entirety of the original investment with unlimited risk it is possible but not necessarily likely to lose many times the amount of the original investment risk varies from investment to investment and one form of assessing risk can be calculated by using the standard deviation of the historical returns or average returns of a specific investment with a higher standard deviation indicating a higher degree of risk though the process may be intimidating investors make high risk investments regularly and for various logical reasons the main justification is that in finance theoretically the greater the risk to an investor the greater the potential return the higher potential return compensates for the additional risk taken on by the investor controlling risk and unlimited riskunlimited risk may make it sound like making certain trades or certain investments is not worthwhile for instance since short selling has theoretically unlimited risk certain traders may avoid it while risk is theoretically unlimited it isn t actually unlimited unless a trader and their broker allow that to happen a trader could enter a short trade in a stock at 5 and decide that they will close the short trade if the price moves up to 5 50 in this case their actual risk is 0 50 per share and is not unlimited the price could gap above their stop loss price of 5 50 say to 6 or 7 this would certainly increase the loss but the loss is still capped to 1 or 2 where the stop loss would trigger in these cases the same concept applies to futures contracts or writing naked options when losing money a trade can be closed the price at which a trader closes the position determines their actual loss it is possible that the loss could be more than they initially invested in the trade or even more than they have in their trading account when this occurs it is called a margin call and the broker will ask the trader to deposit funds in order for them to maintain their position if still open or bring their account balance up to zero if the trading account drops below zero due to a trading loss this means the trader has a debt to the broker example unlimited risk when writing naked optionsassume that a trader is interested in writing naked calls on apple inc aapl the writer will receive the option premium which is their maximum profit if the price of aapl is below the strike price at expiry the option writer gets to keep the premium as their profit on the trade if the price of aapl rises above the strike price the option writer faces theoretically unlimited risk since there is no cap on how high the price could rise the writer has agreed to sell shares of aapl at the strike price to the buyer of the call option this means the option writer will need to buy shares of aapl in order to sell them to the buyer at the strike price regardless of the market price of aapl at that time assume one call option is written with a strike price of 250 which will expire in three months the current price of aapl stock is 240 50 the option is sold for 6 35 which means the writer receives 635 6 35 x 100 shares for one contract if the price of aapl stock stays below 250 the writer keeps the 635 or a portion of it if they close the position early if aapl rises above 250 then they face unlimited losses but they can still control how much they lose to an extent for example if aapl rises to 255 before expiry they may decide to cut their losses and exit their options trade if the price of aapl is trading at 255 at expiry the writer still hasn t lost money this is because they can buy aapl for 5 above the strike price 255 in order to sell it at the strike price 250 they lose 5 there but made 6 35 on the option so they still pocket 1 35 per share less fees if the price of aapl is trading at 270 at expiry the naked option writer has lost money they need to pay 20 more than the strike price 270 250 in order to sell the shares at the strike price 250 they lose 20 here but made 6 35 on the option sale so they end up losing 13 65 per contract their theoretical loss was unlimited but the actual loss was 13 65 per contract this could potentially be reduced through the use of stop losses exiting early when losing buying the shares for a covered call strategy or hedging
