That seems like an extremely foolish investment strategy. If you don't even have $400 in cash you can't even cover some minor unexpected car or house maintenance. Even a minor market correction at the same time as a month or two spent out of work could end up costing you many times more than you could lose in investment income by keeping a few months of expenses in cash..
