You still stock and jump. For techers, stocking starts around the 5th week of the reset.

For casher/farmer, stocking starts about 2 weeks from end of set (about now). If food prices are extremely high, it can start as late as 10 days from end of set (on between 40k-60k land - in the past this used to be 80k land before the building cost formula and military losses for bottomfeeding are increased). Due to large land sizes, (unlike a techer on 25k-35k land), it is still positive cash flow to cash to the last turn of the reset.

In the current food prices, it is likely people will stock the cash on hand as it is and eat corruption. If food is above a certain price, it is calculable that eating corruption is a lesser loss compared to buying food at $60 and selling it at $35 to your PM. You will see, for example, none of the countries above 40k land have started stocking yet; it is still better to grow (grab land), rather than start stocking for another 1-3 more days at most. That is, you can calculate whether gaining X land's worth of production for the remainder Y turns of the entire reset, will give you back more than what you spend grabbing it. What you spend grabbing it includes the cost of jets loss, the oil used, the additional cashing income lost by not using the turns to cash (you use it to spy, PS, build), the construction costs of that X land, and the tech cost (to buy) for maintaining your tech %.

For commies, they don't stock at all because of the 10% commission, it equals a 20% loss of stock right away (sell units, buy food). They instead perform something called a "cash-out" (hitting the cash button), in which they spend money to produce units, until their "upkeep in 1 turn" divided by "NW of units produced in 1 turn" is larger than $254/NW, after which it is better to buy troops and tanks from your PM. This scenario does not happen on Primary because you need to be about 90k-100k land in size before you have any chance of getting close to this $254/NW figure, so Commies cash to the last turn of the reset.

The rules of stocking are the same as on Alliance, the larger your land size, the later stocking starts, and your defenses needs to scale gradually over the course of the reset so you do not look land fat at any time. Comparatively, the land-traders on Alliance that landtrade to 80k land only stock for 6-7 days and take ~2 days to jump, so their stocking only starts 1 week from end of set.
