@Lionel8383:When facing paper losses, an investor has to ask why is the stock price down from when he purchased it. Are revenues and earnings declining for the past few years, or is the decline due to temporary macroeconomic conditions? What is the intrinsic value of the stock? Has the investor over paid for the stock? Is the business a still a good quality business, with a strong economic moat that its competitors struggle to break into? For example, if you look at Apple's annual filing Form 10-K, it mentions that Apple's competitors often sell electronic products are very thin margins, and sometimes those competitors are loss making selling these electronics, in an attempt to undercut Apple's premium pricing. Eventually when the market conditions turn, good quality businesses will eventually recover
