How much cash on hand should one have?
You seem to have a grasp of the basic principles involved, but your estimation of the risk you are taking seems a bit low. Your non-investment reserves are unlikely to cover your expenses for more than a month, so the chance that you would need to sell investments to cover additional expenses is high. You mention that I am flexible with the 'cash on hand' amount. For instance, for about three months I put a very tight spending/investing freeze on my life because I knew I'd be leaving jobs and moving (I already had the other job lined up). Those savings presumably went toward moving expenses, as your usual savings were insufficient. In the event that you are laid off suddenly, you might find yourself in the same position again, with added unplanned expenses like fees for breaking a lease. Your current plan involves selling investments to cover the gap. Based on your age you have probably only invested in a predominantly positive market, so the chance that you might need to sell investments for cash seems like a reasonable trade-off for the added potential gains. Your perception might change if the markets go south and you are forced to sell into a down market, possibly at a significant loss. You also don't indicate if your investments are currently sufficient to cover an extended period of unemployment. You are taking on a lot of risk under your current plan. Essentially you are trading possible investment gains for flexibility and time. By making small changes like saving at least enough to move as you did previously, you can give yourself time to react to job loss or other unexpected financial need. Rather than give the traditional emergency funds advice, I suggest you look at the broader picture. The total amount of savings/risk is up to you, but you should consider your current savings as insufficient to rely on as a safety net.
