QB Stocks - Game Rules
Your comprehensive guide to understanding how to play, strategize, and win in our virtual QB trading beta.
Overall Objective
The goal of the game is to outperform the other investors and increase your 'Portfolio Value'. This is a competitive game of skill and NFL knowledge.
You increase your portfolio value in two primary ways:
- Long Positions: Pick QB stocks that you expect will increase in price week-over-week. (Think: Who will perform better than expected this week?)
- Short Positions: Pick QB stocks that you expect will decrease in price week-over-week. (Think: Who will underperform this week?)
Every week, each investor's portfolio value will go up or down based on the accuracy of their picks.
Your performance is relative to the overall market. Your portfolio has to generate a better return than the average market to increase in value.
The market is defined as the other investors' weighted average performance for that week.
The game is typically played throughout the NFL regular season. At the end of the season, the investor with the highest 'Portfolio Value' is declared the winner.
General Rules
Starting Capital
At the beginning of the season, each investor sets a starting 'Portfolio Value' (e.g., $200 virtual dollars). Usually the group admin will recommend an amount for everyone in the group.
Weekly Picks Mandate
Each week, you must select:
- 3 QB stocks to be long.
- 1 QB stock to be short.
Portfolio Allocation for Longs
For your three long positions, you will select the percentage of your portfolio you want to allocate to each QB stock. These percentages can sum up to 100% of your 'Portfolio Value'.
Example: You allocate 30% of your portfolio to Long 1, 20% to Long 2, and 50% to Long 3. This adds up to 100%.
Short Position Allocation
Your short position is automatically set at an additional 30% of your current 'Portfolio Value'. This 30% for the short does not count against the 100% allocated to your long positions.
(This gives you 130% effective exposure: 100% for longs + 30% for the short)
Cash Rollover
All unused portfolio cash (i.e., if your long positions don't sum to 100% and you explicitly hold cash, or if you default to "all cash") will roll over to the next week but is subject to market relativity. It is generally recommended to invest 100% of your portfolio in long QB positions, because holding cash typically yields a 0% return and may underperform the overall market.
Submission Deadline
You must submit your QB stock picks before the kickoff of the first game relevant to your chosen QBs for that week.
Consequences of No Submission
If you forget, or do not make any new picks, your three long positions will enter the new week holding "all cash" (100% of your investable portfolio is cash). "All cash" usually does not perform well relative to the market.
Price Changes for Non-Playing QBs
QB stock prices will change each week based on performance. If a QB does not play in their scheduled game or records no stats, their price will remain unchanged from the previous week.
Weekly Results Finalization
Weekly results will be finalized after the last NFL game of that week (typically Monday Night Football). These results are used to determine the new QB prices and the new portfolio values for all investors.
The 'Market Multiple' and Real Portfolio Value
- The 'Total Market Value' is equal to all of the investors' aggregate starting portfolio values for that week.
- After the results come out each week, each investor will have a 'Nominal Portfolio Value' based on the raw performance of their picks.
- The 'Market Multiple' for the week is calculated as: Total Nominal Value of all Investors (after results) / Total Market Value (aggregate starting values).
- Each investor's 'Nominal Portfolio Value' is then divided by that week's 'Market Multiple' to arrive at their 'Real Portfolio Value'.
- The sum of all investors' 'Real Portfolio Values' will always equal the original 'Total Market Value' for that week.
Example: An investor begins the week with a $200 Portfolio Value. Based on their QB's performance, their 'Nominal Portfolio Value' increases to $450. If the 'Market Multiple' for that week is 1.5x, their 'Real Portfolio Value' is adjusted to $450 / 1.5 = $300. This $300 becomes their buying power for the following week.
Elimination
If your 'Portfolio Value' drops to zero or goes negative, you are out of the game.
How are QB Stock Prices Calculated?
QB stock prices are calculated based on the following updated formula (effective 2025 season):
Price =
[(Previous Week's Price) / 4]
+ [(Completion Percentage * 10) / 4]
+ [(Total Yards * 2.5 / 100) / 4]
+ [(Total TDs - Total Turnovers) * 2.5 / 4]
+ [$0.25 for a WIN or -$0.25 for a LOSS]

QB stock prices cannot go below $0.01. (The components like (Total TDs - Total Turnovers) can be negative, and a loss adds a negative value, potentially driving the raw calculation negative before the $0.01 floor is applied.)
Example: Russell Wilson had a completion percentage of 64.3%, 339 total yards, 4 total TDs, 1 total turnover, the Broncos won, and his previous week's price was $6.50. His new stock price is calculated as: ( (6.50)/4 ) + ( (64.3 * 10)/4 ) + ( (339 * 2.5 / 100)/4 ) + ( ((4-1) * 2.5)/4 ) + 0.25 = $1.63 + $1.61 + $2.12 + $1.88 + $0.25 = $7.49
Minimum Snaps
There are no minimum snaps needed to create a price as long as the QB records at least one statistic. If a QB is inactive, or active for a game but records zero in all statistical categories, their price will remain unchanged from the previous week.
Trading Restrictions
Position Concentration Limits
Hold a single long stock that represents over 50% of your portfolio value or under 10% of your portfolio value. (This rule encourages diversification and meaningful position sizes.)
Exception: The 'pink-sheet' or 'hard-to-borrow' rules described below.
Long Position Aggregate Limit
Have your three long positions, in aggregate percentage allocation, be greater than 100% of your 'Portfolio Value'.
'Pink-Sheet' Restriction (Low-Priced Stocks)
Buy a QB stock that has a price of less than $3.00.
Reasoning: Very low-priced stocks can have extreme percentage volatility with small absolute price changes, potentially distorting game balance.
Exception: If one of your existing long positions drops below $3.00 (becomes a 'pink-sheet'), you can choose to keep it for the following week. If you do, the number of shares will stay the same as the previous week.
'Hard-to-Borrow' Restriction (High-Priced Stocks for Shorting)
Short a QB stock that has a price greater than $7.00.
Reasoning: Very high-priced stocks are easy short picks. We want the decision to short a QB to come with some risk.
Exception: If your existing short position rises above $7.00 (becomes 'hard-to-borrow'), you can choose to keep it as your short for the following week. If you do, the number of shares will stay the same as the previous week.
Viewing Picks
Historical Picks
To see past picks, click on an investor's name on the 'Investors' tab (or equivalent section).
Current Week's Picks
Refer to the 'Picks' tab (or equivalent) to see picks submitted for the current, unplayed week.
Injured or Non-Playing QBs
QB Does Not Play/No Stats
If the QB does not play in the game or does not record any statistic, his price will remain unchanged from the previous week.
QB Injured During Game
If the QB gets injured during the game, his recorded stats up to that point will count when calculating his new price. There is no minimum snap count required if stats are recorded.
Pick Submission Confirmation
Successful Submission
If you see your name and picks on the 'Picks' tab (or receive a confirmation message), your picks have been submitted successfully.
Changing Picks
You can change your picks by submitting again. Changes can be made up until that specific QB's game has started or the general weekly deadline.
Error Messages
If you see an error message on the 'Trade' tab (or equivalent), you must correct your picks before they can be successfully submitted.
Troubleshooting
If having trouble submitting (especially on a computer), try using a phone, refreshing the browser, and trying again.
Real-Time Pricing (During Games)
Concept
Real-time pricing uses live stats to show indicative performance of stocks and investor portfolios while NFL games are being played.
Calculation
A QB's real-time price is an estimate, often calculated as: (QB's previous week stock price * % of game time remaining) + (calculated stock price based on QB's live stats in the current game so far)
.
Example: A QB enters the week with a price of $4.00. He's played one quarter (75% of game time remaining). In that quarter, his live stats equate to a $2.00 current game segment price. His 'Real-Time' stock price estimate: ($4.00 * 0.75) + $2.00 = $3.00 + $2.00 = $5.00.
Impact
These real-time stock price estimates can be used to show real-time portfolio value changes and indicative 'Market Multiple' shifts during game day.
Finality
After all games are over, the real-time stock prices should converge to the final calculated stock prices. These final prices are official and used for making picks for the subsequent week.
Pick Basis
Weekly picks are always made using final prices from the previous week, never based on in-game real-time prices.
