Thats a tough one. Ideally I would sit on it if you can. If you pull them out now at a much lower value than your initial investment, even if you put them into something else you deem low risk, you are still holding a loss. Even those companies supposedly more stable than others are not immune to great losses, as we are seeing in the current market crash.

It depends on the specific investment though. Do you expect these stocks to resume value as the market recuperates? This may take a good few years and you would need to be able to see them through to that period.

There is the other side of the coin however, is that with many historically stable high return stocks trading lower than usual, it can be an ideal time to buy.

If I were you I would speak to a financial advisor and make an informed decision based on your portfolio and the current stock market.

hello  , dear ...this a so so question...as you mentend that you there is a massive loss in my suggestion it is better to stop at that point .wait i am not finisiing ..let me describe if you give a break for a while..there will be some benefits .the are as follows :-

1. you get at least some figure of money in your hand ..i know it is not so much but enough to think back to cover loss. 

2. the fear of insecurity will not grow rapidly which will if rapidly grow there will be a issue with your heath in future...it will not happened

3. you have now a free of tension brain which is as most need as need oxizen for live. to cover loss. which you would not got if you do not stop suddenly at this point

these are some of the points i figuared-out . ok but your problerm still exsist.In this moment my advice is to add some more money and get a 100% loss proof method (just kidding) there is nothing such that....but but there is defenately almost low profit and low risk plan...invest on them......and recover your loss by slowly but seadily ....

                                 HOPE I HELPED YOU AT LEAST MINIMUM POINT THANKS
