There are too many factors involved to give a straight yes or no answer!
Ignore the fact that there is an economic downturn and just consider the same points you would at any other time - such as would you be trading at a significant loss and if so, would reinvesting recover any trading loss you make? If gold is at a top price now, is the only way back down? How relatively 'safe' are the shares you hold (eg scarred for life's comment)? Are you invested for the long-term etc.
Stock market trading is a gamble, some you win, some you lose. Hopefully you win more than you lose!
