What is quotational loss in stock market?
Been a long while since I've read it but if I remember correctly with quotational loss Graham refers to an unjustified decline in stock price because of Mr. Market's fear and loathing where the business prospects of the company are actually still sound.  This is opposed to "actual" loss of capital which he would consider to be a company going bankrupt or just more generally turning out to have way worse business prospects than expected with the justified decline in stock price that entails.
