What the Buck Investment Papers are stock certificates that land in your tray instead of on the table. You open one, watch its price chart, buy extra shares while the price is low, and tear the paper for cash while it is high. confirmed They are the last money mechanic in the game, unlocked from the $100 branch of the skill tree, and they decide how fast you close the final gap to the ending. confirmed

How to unlock Investment Papers

Buy Paper Trail in the $100 branch of the skill tree. On release day its text read: a 0.04% chance for a withdrawn bundle to be an investment paper with stocks; tear it while the chart is high to destroy the most money, and while the chart is low buy extra shares so the next high pays more. confirmed Unlocking it earns the Paper Trail achievement. confirmed

The papers collect in a tray at the side of the table. A pre-release key showed the tray holding up to 99 papers. confirmed

When to cash out What the Buck stocks

The rule is in the node text itself: buy shares while the chart is low, tear while it is high. confirmed A few practical points from release-day play:

  • Time seems to stop while the stock screen is open. The release-day 100% player noticed the chart only moved after he started the market, so you can read the chart without losing table time. reported
  • Buy in bulk at a dip. That player used an auto clicker to buy dozens of shares at a low point, then waited for a spike above his entry line. confirmed
  • Early papers are not worth much waiting. Before his upgrades, one trade returned about 4 quintillion and he judged the waiting not worth it. reported
  • Late papers are huge. With share-value nodes bought, single trades returned 283 quintillion, and doubling his money through stocks a few times took him over the $1 sextillion goal. confirmed

Upgrades for Investment Papers

The $100 branch continues past Paper Trail with share value, shares on every withdrawn paper, the chance for a bundle to be a paper, paper payout and a “controlling stake” node (+22% share value seen on release day). A pre-release key also showed a node that makes papers arrive a grade higher. confirmed

Buy share value and shares per paper first. Paper chance matters less, since the tray fills up anyway late in a shift.

How Investment Papers fit the endgame

By the time you have Paper Trail, your panels are close to max and the shift price is in the quadrillions. Papers are the only income that scales with patience instead of upgrades, which is why the release-day 100% run spent its final minutes trading stocks. See the ending and 100% guide for that last stretch.

Investment Paper checklist

  • Unlock Paper Trail once the $100 income nodes are bought.
  • Open papers when you have spare money to stake.
  • Buy shares only below your entry line.
  • Tear on a spike above the line; do not wait for a perfect top.
  • Use papers to double money near the goal, not as your main income mid-game.
