Investment in sole proprietorship

hello..... my 1st query is "can we show the personal invesments made by a sole proprietor in shares, mutual funds etc as drawings"......... i dont think its compulsory to show it in p/l ac as it is not related directly to the business and it can be termed as personal for sole proprietorship.. my 2nd query is dat normally we show investment(capital) losses in the p/l ac, but there is no such coloumn in p/l ac of itr4 where we can show this loss,, should we show this loss as other expense ???........ its urgent, pls reply asap
