Stock Market

The Stock Market minigame as of v2.052

The Stock Market is a Minigame in Cookie Clicker based on the Bank building. In the Stock Market, players can purchase cookies, recipes and ingredients, and sell them at higher prices for a surplus of cookies measured in the American dollar ($), where each dollar is equivalent to 1 second of highest unbuffed CpS obtained during the ascension.

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 progress (profits/losses, office levels, and bought goods) does not persist between ascensions.

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.

Icon	Name	Description	Office Level	Cost to Upgrade
	Credit garage	This is your starting office. Upgrading will grant you: +25 warehouse space for all goods	1	100 Cursors (level 2+)
	Tiny bank	This is your office. Upgrading will grant you: +1 loan slot +50 warehouse space for all goods	2	200 Cursors (level 4+)
	Loaning company	This is your office. Upgrading will grant you: +75 warehouse space for all goods	3	350 Cursors (level 8+)
	Finance headquarters	This is your office. Upgrading will grant you: +1 loan slot +100 warehouse space for all goods	4	500 Cursors (level 10+)
	International exchange	This is your office. Upgrading will grant you: +1 loan slot +50% base warehouse space for all goods	5	700 Cursors (level 12+)
	Palace of Greed	This is your office. It is fully upgraded. Its lavish interiors, spanning across innumerable floors, are host to many a decadent party, owing to your nigh-unfathomable wealth.	6	N/A

Stockbrokers

Icon	Description
	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 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."

Overhead

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 based on number of brokers is as follows:

${\text{Overhead}}=0.01\times 20\times 0.95^{\text{Brokers}}$

This graph shows the number of brokers needed to get the desired overhead reduction. For example, at 59 brokers the overhead is already lower than 1%, compared to the original 20%.

Loans

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."

The costs of a loan is very steep, and they must be used at the right opportunity to be worthwhile. The best time to use them is during a Golden Cookie combo (stacking multiple Golden Cookie effects at once). A loan's bonus is multiplicative and stacks with other buffs (including other loans).

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. Some rules are affected by Dragon Auras; Supreme Intellect and Reality Bending. Each stock has a hidden delta value that decreases by 3% every tick (2% with Supreme Intellect, 2.9% with Reality Bending, or 1.9% with both). One tick occurs every minute. This delta value is added to the value of the stock every tick and acts as a sort of velocity for the stock. Stocks also have a resting value, based on the Bank level, calculated as follows.

${\text{Resting value}}=10\times (id+1)+{\text{Bank level}}-1$

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 $179 for Publicists. Every tick, the value of the stock is gradually shifted toward this value by 1%. Being updated as follows.

$value+=({\text{Resting value}}-value)\times 0.01$

After this, the stock's value is fluctuated by a random amount between -3 and 3 using the following formula:

$value+=3\times {\text{random}}[-1,1]^{11}$

Then its delta is fluctuated by a random amount between -0.05 and 0.05. There is a 15% chance that the stock's value is fluctuated by an additional random amount between -1.5 and 1.5 (with linear distribution), a 3% chance that the value is fluctuated by another additional random amount between -5 and 5 (between -10 and 10 with Supreme Intellect, between -5.5 and 5.5 with Reality Bending, or between -10.5 and 10.5 with both), and a 10% chance that the stock's delta is fluctuated by an additional random amount between -0.15 and 0.15 (between -0.25 and 0.25 with Supreme Intellect, between -0.16 and 0.16 with Reality Bending, or between -0.26 and 0.26 with both).

On top of that, each stock is in 1 of 6 modes with custom additional rules. Stock modes are stored as numerical IDs between 0 and 5. These rules apply once every tick, in addition to the rules listed above that apply regardless of mode.

Standard Mode Selection

ID	Mode	Chance	Details
0	Stable	12.5%	The stock's delta is decreased by 5%, then fluctuates by a random value between -0.025 and 0.025.
1	Slow Rise	25%	The stock's delta is decreased by 1%, then fluctuates by a random value between -0.005 and 0.045.
2	Slow Fall	25%	The stock's delta is decreased by 1%, then fluctuates by a random value between -0.045 and 0.005.
3	Fast Rise	12.5%	The stock's value fluctuates by a random value between 0 and 5, 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.
4	Fast Fall	12.5%	The stock's value fluctuates by a random value between -5 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.
5	Chaotic	12.5%	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 (between -4 and 4 with Supreme Intellect, between -1.3 and 1.3 with Reality Bending, and between -4.3 and 4.3 with both).

When a stock changes mode it is assigned a random duration value between 10 and 700 (between 10 and 500 with Supreme Intellect, between 10 and 680 with Reality Bending, or between 10 and 480 with both) that decreases every tick. A new mode is chosen when this time runs out, according to the probabilities above. 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. With Supreme Intellect, there is a 50% chance the stock completely bypasses normal selection and instead turns Chaotic (5% with Reality Bending, and 50% with both).

Additionally, every tick there is a 10% chance of triggering a round of instant mode changes (20% with Supreme Intellect, 11% with Reality Bending, or 21% with both). When this happens, a single random value between -1 and 1 is chosen to apply to all affected stocks, called globD, and each stock is selected at random (25% of them on average) to instantly reselect its mode and suddenly fluctuate its value and delta based on this globD as follows:

• The stock's value is randomly fluctuated between 2 and 9 + 7×delta scaled by -globD:

$value+=-globD\times (2+7\times {\text{random}}[0,1]^{3}+7\times delta\times {\text{random}}[0,1]^{3})$

• The stock's delta is uniformly fluctuated between 1 and 5 scaled by globD:

$delta+=globD\times {\text{random}}[1,5]$

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.

${\text{Market cap}}=100+3\times ({\text{Bank level}}-1)$

With Supreme Intellect

The Stock Market without (top) and with (bottom) Supreme Intellect, starting from the same point.

The following is a summary of all the aspects of the Stock Market affected by Supreme Intellect (Base Value / Supreme Intellect / Reality Bending / Both Auras):

1. The severity of base delta decrease each tick
   • Severity: 3% / 2% / 2.9% / 1.9%
2. The severity of the 3% chance to randomly change the stock value
   • Severity: -5 to 5 / -10 to 10 / -5.5 to 5.5 / -10.5 to 10.5
3. The severity of the 10% chance to randomly change the stock delta
   • Severity: -0.15 to 0.15 / -0.25 to 0.25 / -0.16 to 0.16 / -0.26 to 0.26
4. The severity of the 20% chance of selecting a new random stock delta when the stock is Chaotic
   • Severity: -1 to 1 / -4 to 4 / -1.3 to 1.3 / -4.3 to 4.3
5. The maximum possible duration for a newly selected stock mode
   • Maximum duration: 700 / 500 / 680 / 480
6. The chance to bypass standard mode selection and instead become Chaotic
   • Bypass chance: 0% / 50% / 5% / 50%

Strategy

If you feel as though a stock is in a slow or fast rise, buy it as soon as possible, and sell when it starts to decrease. While selling when the stock price is over resting value seems like a good idea, it has been made nearly irrelevant since the stock market rework.

Supreme Intellect often makes stocks reach abnormally high or low prices, which makes obtaining the stock market achievements easier.

After you unlock all achievements, it is recommended to not use the Stock Market again (except for loans) as a lot of time is required for minimal gain as compared to other minigames.

Increasing the highest raw CpS after buying a stock will make the stock sell for more while not needing to wait for it to rise or fall. This may be used to pay back the initial investment dozens of times over.

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:

Code

Game.attachTooltip( Game.Objects['Cursor'].l, Game.Objects['Bank'].minigame.oppTooltip(), this ); Game.attachTooltip( Game.Objects['Grandma'].l, Game.Objects['Bank'].minigame.refillTooltip, this );

Opportunity lump use.

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".

Trivia

• 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).
• The text 'Dough Jones Index' in the stock market background is a reference to the Dow Jones Index.
• Do note that your progress towards achievements like Liquid Assets (earn $10 million in profit) and Gaseous assets (earn $31 million in profit) will be reset upon ascension.
• The stock market is generated when unlocked, so reloading and unlocking will change the stock market's prices and modes.
