The Stock Market minigame as of 2.028

The Stock Market is a minigame implemented in version 2.028 on August 23, 2020. The minigame is unlocked by upgrading Banks to Level 1. In the Stock Market, players can purchase cookies, recipes and ingredients, and sell them at higher prices for $ (meaning seconds of maximum raw CpS).

In addition to buying and selling resources, the minigame includes an Office, which can be upgraded to increase warehouse capacity and unlock Loans; as well as Stockbrokers, which reduce the overhead cost of buying resources. Loans cost cookies and increase the current CpS for a certain amount of time, but after the time is over, CpS is decreased for a significant amount of time.

Each aspect of the Stock Market is associated with a building. The Office is associated with Cursors, the Stockbrokers are associated with Grandmas, and the resources are each associated with one of the remaining buildings.

Stock Market Offices

Upgrading your Office increases the warehouse capacity of each resource, and several upgrades also unlock loan slots. Upgrading costs a certain amount of Cursors and require the Cursors to be at a certain level.

Stockbrokers.png A nice broker to trade more cookies.

  • Buying goods normally incurs overhead costs of 20% extra. Each broker you hire reduces that cost by 5%.
  • Buying a broker costs Money.png 20 minutes of CpS (that's $1200).
  • Maximum number of brokers you can own: the highest number of grandmas you've owned this run, divided by 10, plus your grandma level.
"Brokers are Wall Street-class grandmas versed in the ways of finance. Stockbroker grandmas work hard and play hard, and will fight telephone in hand to get your clients the best possible deals - with a sizeable profit margin for you, of course."


The Overhead is the number of cookies you will pay on top of any stock purchase. By getting Stockbrokers this overhead can be minimized to extremely low values, which makes buying-and-selling stock much more profitable.

The 5% reduction is applied multiplicatively, meaning that each new Stockbroker provides lesser reduction than the previous ones. The formula for calculating the overhead (in %) based on number of brokers is as follows:

The following table shows the number of brokers needed to get the desired overhead reduction, as well as total price to buy that number of brokers (in $). For example, at 59 brokers the overhead is already lower than 1%, compared to the original 20%.

Loans are unlocked by leveling up your offices. The buttons to trigger them are located just under or to the right of the stockbroker information, depending on zoom level and window size. At max level, there are 3 loan slots, each providing a different CpS boost. On every loan, you must pay a downpayment of a certain percentage of your bank.

Slot Type Description
1st Modest loan By taking this loan, you will get +50% CpS for the next 2 hours.
However, you will get -75% CpS for the next 4 hours after that.
You must also pay an immediate downpayment of 20% of your current bank.
"Buy that vintage car you've always wanted. Just pay us back."
2nd Pawnshop loan By taking this loan, you will get +100% CpS for the next 40 seconds.
However, you will get -90% CpS for the next 40 minutes after that.
You must also pay an immediate downpayment of 40% of your current bank.
"Bad credit? No problem. It's your money, and you need it now."
3rd Retirement loan By taking this loan, you will get +20% CpS for the next 2 days.
However, you will get -20% CpS for the next 5 days after that.
You must also pay an immediate downpayment of 50% of your current bank.
"Finance your next house, boat, spouse, etc. You've earned it."

Generally, loans are not worth it in the end, as the costs far outweigh the benefits. The best time to use them is during an Elder Frenzy, Frenzy, Click Frenzy, Dragon Harvest, Building Special or Dragonflight to provide the biggest boost.

A strategy would be to take out a retirement loan, but have your ascension last less than 2 days. This would completely avoid the 5 day penalty. Another strategy would be to, during the Christmas Season, activate the Grandmapocalypse. This would give a chance of the legendary Elder Frenzy and Reindeer combo (an achivement in itself). By purchasing the Christmas-themed upgrade Ho-ho-ho flavored frosting, this would give 12 hours and 6 minutes worth of CpS. By triggering a pawnshop loan slightly before the boost, this would give over a day of regular production. Add a Frenzy, which is fairly easy to get, you'll have over a week's worth of cookies. Loans might have some unfair effects, but the boosts they provide, if used correctly, can seriously offset the negatives.

Stock Market Resources

The base warehouse capacity of each resource is the highest amount of that building you've owned in the current ascension, plus ten times the building's Level. The +50% base capacity from Palace of Greed is calculated solely from the 'highest amount of that building' value before considering each building's Level or the additive capacity upgrades from lower level Offices.

Market Behavior

The value of stocks on the market is random but conform to a number of rules. Each stock has a hidden delta value that decreases by 3% every minute. This delta value is added to the value of the stock every minute and acts as a sort of velocity for the stock. Stocks also have a resting value, based on the Bank level, calculated as follows.

Where id is its index: CRL being 0, CHC being 1, etc.

So, for example, if you have level 10 Banks, the resting value would be $19 for Cereals and $159 for Recipes. Every minute, the value of the stock is gradually shifted toward this value by 2%. Being updated as follows.

After this, the stock's value is fluctuated by a random amount between -0.2 and 0.2 and its delta is fluctuated by a random amount between -0.05 and 0.05. Additionally, there's a 10% chance that the stock's value is fluctuated by a random amount between -1.5 and 1.5 and another 10% chance that its delta is fluctuated by a random amount between -0.15 and 0.15.

On top of that, each stock is in one of 5 modes with custom additional rules. These rules apply once every minute. When a stock changes mode it gets a random duration value between 10 and 1000 that decreases every minute. A new mode is chosen when this time runs out, according to the probabilities below. If the stock is in a Fast Rise or Fast Fall while changing mode, there is a 70% chance that it turns Chaotic instead of choosing a mode normally.

Stable (12.5% chance)

The stock's delta is decreased by 5%, then fluctuates by a random value between -0.025 and 0.025.

Slow Rise (25% chance)

The stock's delta is decreased by 1%, then fluctuates by a random value between -0.005 and 0.045.

Slow Fall (25% chance)

The stock's delta is decreased by 1%, then fluctuates by a random value between -0.045 and 0.005.

Fast Rise (12.5% chance)

The stock's value fluctuates by a random value between 0 and 1, and its delta fluctuates by a random value between -0.015 and 0.135. There is a 30% chance of the stock's value fluctuating by an additional random value between -7 and 3, and its delta fluctuating by a random value between -0.05 and 0.05. There is also a 3% chance of the stock changing mode to a Fast Fall.

Fast Fall (12.5% chance)

The stock's value fluctuates by a random value between -1 and 0, and its delta fluctuates by a random value between -0.135 and 0.015. There is a 30% chance of the stock's value fluctuating by an additional random value between -3 and 7, and its delta fluctuating by a random value between -0.05 and 0.05.

Chaotic (12.5% chance)

The stock's delta fluctuates by a random value between -0.15 and 0.15. There is also a 50% chance that the stock's value fluctuates by an additional random value between -5 and 5, and a 20% chance that its delta is overridden by a random value between -1 and 1.

Lastly, the value of a stock has a hard limit of never falling under $1, and when the value is less than $5 the value of the stock is increased by (5 - value)/2, half the distance to $5. If its delta is negative while the stock value is less than $5, the delta is decreased by an additional 5%. If a stock's value surpasses the market cap, its delta is decreased by an additional 10% if it is positive. The market cap is calculated based on the Bank level as follows.


The under-lying strategy for getting profit in the stock market is to buy low, and sell high. Therefore, it is recommended that you calculate the resting value for each stock (10 x (id+1) + Bank level -1, with id being the stock, CRL being 0, CHC being 1 and so on) and to buy when the stock is significantly below this price, and sell when it goes back to its resting value or higher. Because the game does not show when you bought the stock and at what price you bought it at, it is recommended to make some kind of text document, showing the resting value of each price and then writing down the price you bought the stock at. If you feel as though a stock is in a slow or fast rise, buy it as soon as you can, and sell when it starts to stabilise. You may feel as though you're holding onto stocks for a long time, waiting for them to increase in price; this is normal, as some stocks may stay in the stable mode for hours. Stock market is about patience: waiting for the right time to buy at a low price, and waiting eventually for it to rise. Higher priced stocks are more risky to invest in, due to the fact that making a loss on a sale on a high priced stock will drastically reduce overall profit, but this can happen with all types of stocks.

Alternatively, to avoid calculating the resting value or keeping note of prices when bought, duplicate this spreadsheet and fill it in with your own price data over time. It will give recommendations to buy or sell based on the average prices of your stocks over time.[1]

Unused "Opportunities"

Opportunity tooltip.

In the code for the Stock Market minigame, there is an unused section of code which allows the player to generate opportunities. Opportunities allow the player to manipulate the stock market to "some degree", with 3 options to choose from. It is thought that these opportunities may be similar to the modes currently used, but the player can stop and start them at will, or may have been in place before loans, possibly due to the fact that they depend on the office level and have 3 options, similar to the loans. The tooltips for opportunities can be accessed by adding this code into the console, and hovering over the Cursor:

Game.Objects.Cursor.l.onmouseover = function() { Game.tooltip.dynamic = 1 Game.tooltip.draw(this, Game.Objects.Bank.minigame.oppTooltip(), 'store') Game.tooltip.wobble() } Game.Objects.Grandma.l.onmouseover = function() { Game.tooltip.dynamic = 1 Game.tooltip.draw(this, Game.Objects.Bank.minigame.refillTooltip(), 'store') Game.tooltip.wobble() }

Additionally, this code allows the player to hover over the grandma to see how sugar lumps would've been used. Opportunities can only be used once an hour; sugar lumps refill this timer and also "give a quick burst to the economy".

Opportunity lump use.


  • The stock market is so far the only minigame that doesn't allow the player to spend sugar lumps to speed up the process (although there is an unused piece of code that allows this, see above).

  2. Used to be a normal achievment, changed to shadow in update 2.031, and replaced with an achievement requiring only $10 million profit.
